Blackmores Alternatives Australia 2026: Sleep, Mood and Liver

Last updated: November 1, 2026 · Originally published: October 29, 2026 · By Eternal Elixir Editorial

Blackmores alternatives in Australia are worth comparing when you want one studied ingredient at a clear dose, rather than a herbal blend in a pack that runs out within a few weeks. Blackmores is on almost every chemist shelf in the country, and its sleep, mood and liver products are easy to find. This guide lines up three of them against four single-ingredient capsules from Eternal Elixir on price, serve, dose per serve, cost per day and pack size. Eternal Elixir makes the four capsules ranked first, so read it as a comparison from a brand with a stake in the answer.

Quick answer: The Blackmores alternative we rank first in Australia is Eternal Elixir Saffron Extract 30mg. Eternal Elixir makes Saffron Extract 30mg; it is our pick for mood and everyday wellbeing because each capsule carries 30mg of affron saffron, close to the 28mg a day that improved mood scores in a 4-week trial, and a 90-capsule bottle costs $49.99, about $0.56 a day. Blackmores Calm & Relax, the nearest Blackmores tablet in this lane, works out to about $0.87 a day at its full label serve.

If sleep is the priority, our pick is Eternal Elixir Magnesium L-Threonate 2000mg, $59.99 for 30 serves. For liver and antioxidant support, Eternal Elixir TUDCA 500mg costs about $0.67 a day and Eternal Elixir Reduced L-Glutathione 2000mg about $0.89 a day, against about $1.71 a day for Blackmores Milk Thistle at three tablets daily. The full table, the trial details and the trade-offs follow.

Blackmores alternatives in Australia compared on cost per day

Each row uses the serve printed on the label. Cost per day is the pack price divided by the number of days one pack lasts at that serve, rounded to the nearest cent. Eternal Elixir prices come from our product pages and Blackmores prices from the Blackmores Australia website.

Prices as of Oct 2026. Blackmores prices are the ones shown on blackmores.com.au; Chemist Warehouse, Priceline and other chemists set their own shelf prices and run regular promotions, so the price in your local store may differ. Every Eternal Elixir batch is third-party lab tested for purity, and the current batch certificate of analysis is sent on request.

Why these three Blackmores products? Each one is sold in a single pack size at a single price on the Blackmores website, so the cost per day is exact rather than based on a “from” price that may belong to a small pack. Sleep Sound Magnesium is the Blackmores sleep product with the clearest single-nutrient dose, Calm & Relax is the closest Blackmores product to a mood-lane capsule, and Milk Thistle is the Blackmores liver product most shoppers know. Products sold in several sizes, such as Deep Sleep and Magnesium Glycinate, are covered further down but not ranked.

This guide is a roundup of alternatives across three lanes, not a brand-against-brand contest. If you are choosing between the two big chemist brands, our Swisse vs Blackmores comparison puts their berberine, saffron and liver products head to head.

1. Eternal Elixir Saffron Extract 30mg: our mood pick

In the Blackmores range we checked, mood is the clearest gap. Of the nine products in the Blackmores stress relief and sleep support category in Oct 2026, none is a saffron extract; the range leans on B vitamins, magnesium and traditional herbs such as lavender, passionflower and valerian. Saffron is the ingredient with the most direct human mood data at a one-capsule dose, which is why Eternal Elixir Saffron Extract 30mg leads this ranking.

Each capsule holds 30mg of affron, a saffron stigma extract standardised to 3.5% Lepticrosalides, and it is the branded extract used in the trials below. The label serve is one capsule daily with a meal, so a bottle of 90 capsules lasts three months. At $49.99, that is about $0.56 a day, and bundle pricing takes 10% off two bottles, 15% off three and 20% off five.

The main mood trial, published by Kell and colleagues in Complementary Therapies in Medicine in 2017, randomised 128 healthy adults who reported low mood to affron at 28mg a day, affron at 22mg a day or placebo for 4 weeks. The 28mg dose improved total mood disturbance scores against placebo, while the 22mg dose showed no difference from placebo. Screening and outcomes were self-reported, and one author was affiliated with Pharmactive Biotech Products, the company behind affron. Our 30mg capsule sits just above the dose that worked.

Saffron also has sleep data. In a 2020 trial in the Journal of Clinical Sleep Medicine, Lopresti and colleagues gave 63 adults with self-reported poor sleep 14mg of affron twice a day or placebo for 28 days. The saffron group reported greater improvements in sleep-quality questionnaire scores, restorative sleep scores and sleep-diary quality ratings, and Pharmactive funded the trial. Mood and sleep tend to move together, so one capsule with data in both lanes is good value.

Against Blackmores Calm & Relax, the trade is simple. Calm & Relax is a four-herb tablet built on traditional use, at two tablets a day and about $0.87 a day. Saffron Extract 30mg is one capsule of one studied extract at about $0.56 a day, in a bottle that lasts three times as long.

For a plain-language look at the ingredient itself, our guide to saffron supplement benefits covers mood, sleep and stress. If you are also weighing another chemist brand, our Herbs of Gold alternatives roundup covers saffron and magnesium threonate against that range.

Pros

• One capsule a day of a single branded extract, at a dose just above the 28mg a day that improved mood scores.
• 90 capsules per bottle, a three-month supply.
• Lowest cost per day in this comparison, about $0.56.
• Human trial data for both mood and sleep quality.

Cons

• Both trials ran for about four weeks, and the extract’s maker was involved in both.
• The trials measured change over weeks, so do not expect a big difference on the first night.
• Sold online, so you cannot pick it up from a chemist on the way home.

Best for: adults who want daily support for mood and everyday wellbeing from one capsule, at the lowest cost per day in this comparison.

Facts: 30mg affron per capsule; 90 capsules, 90 serves; $49.99, about $0.56 per day. As of Oct 2026.

2. Eternal Elixir Magnesium L-Threonate 2000mg: our sleep pick

Magnesium runs through the Blackmores sleep offer: it appears in Deep Sleep, in Sleep Sound Magnesium and as a stand-alone glycinate tablet. Eternal Elixir Magnesium L-Threonate 2000mg uses a different form, magnesium L-threonate, which is the form tested on its own for sleep in the trial below. That is why it is our pick for sleep rather than a higher-magnesium powder.

Each serve is three capsules, giving 2,000mg of magnesium L-threonate and about 144mg of elemental magnesium. A bottle holds 90 capsules, 30 serves, for $59.99, which is about $2.00 a day. The label says to take the three capsules daily with a meal, and our product page suggests taking all three in the evening if sleep is your goal.

The trial, published by Hausenblas and colleagues in Sleep Medicine: X in 2024, randomised 80 adults aged 35 to 55 with self-reported sleep problems to 1g of magnesium L-threonate a day or placebo for 21 days. The magnesium group kept good sleep quality and daytime functioning while the placebo group declined, and wearable-ring data showed better deep sleep and REM sleep scores. Participants taking magnesium also rated their energy, mood and mental alertness better than placebo. Author affiliations include the ingredient company AIDP, and this is one 21-day trial rather than a body of work.

Our serve is 2,000mg, twice the 1g a day used in the trial, so you are taking more than the studied amount rather than less. We state that plainly so you can decide with the full picture.

Here Blackmores wins on two numbers. Sleep Sound Magnesium gives 320mg of magnesium per scoop, more than twice the 144mg in our serve, and costs about $1.80 a day against our $2.00. What it does not give you is the threonate form, which is the one with a stand-alone sleep trial; its magnesium comes mainly from citrate, with glycine and hops added. For the wider field, including sleep ingredients beyond magnesium, our ranking of sleep supplements in Australia compares the main options on cost.

Pros

• The magnesium form with a stand-alone sleep trial in adults aged 35 to 55.
• Capsules, with no scoops or mixing.
• Single ingredient, so it is easy to combine with saffron for a mood and sleep routine.
• 2,000mg per serve, above the 1g a day used in the trial.

Cons

• Highest cost per day in this list, about $2.00.
• Less elemental magnesium per serve than Blackmores Sleep Sound Magnesium.
• 30 serves per bottle, so you reorder monthly.
• One trial with industry-linked authors, not a large body of research.

Best for: adults who want to support sleep quality with the magnesium form studied on its own for sleep, in capsules rather than a powder.

Facts: 2,000mg per 3-capsule serve (about 144mg magnesium); 90 capsules, 30 serves; $59.99, about $2.00 per day. As of Oct 2026.

3. Eternal Elixir Reduced L-Glutathione 2000mg: our antioxidant pick

Glutathione is an antioxidant your own cells make from three amino acids, cysteine, glutamate and glycine, and the liver holds some of the highest concentrations in the body. We did not find a stand-alone glutathione capsule in the Blackmores Australia range we checked for this guide. So if antioxidant support is the goal, Eternal Elixir Reduced L-Glutathione 2000mg fills a gap rather than replacing a like-for-like product.

Each serve is two capsules, 2,000mg of reduced glutathione, taken daily on an empty stomach. A bottle holds 90 capsules, 45 serves, for $39.99, which is about $0.89 a day and the lowest shelf price of our four picks. Reduced glutathione is the form the body uses directly, and the only other ingredients are rice flour and the capsule.

Oral glutathione was long assumed to break down before it could do much. A 6-month randomised trial by Richie and colleagues, published in the European Journal of Nutrition in 2015, tested that in 54 non-smoking adults taking 250mg or 1,000mg a day or placebo. At 6 months, the higher dose raised glutathione levels by 30 to 35% in red blood cells, plasma and lymphocytes, showing that daily oral glutathione can increase the body’s stores. Our 2,000mg serve is above the highest dose in that trial.

Glutathione does not work like a traditional liver herb. It supports the body’s normal antioxidant defences, including in liver cells, and the trial above measured glutathione levels rather than how people felt. If you are comparing glutathione costs across practitioner brands, our BioCeuticals alternatives guide works out the price per gram, and our Metagenics alternatives roundup covers glutathione and liver formulas from another practitioner range.

Pros

• Lowest shelf price of our four picks, $39.99.
• 2,000mg per serve, above the doses used in the 6-month human trial.
• Reduced form, single ingredient, short ingredient list.
• 45 serves per bottle, a month and a half at the label serve.

Cons

• Best taken on an empty stomach, which takes a little planning around meals.
• Two capsules per serve.
• The evidence measures glutathione levels, not day-to-day feel.
• No direct Blackmores equivalent, so this is an addition rather than a straight swap.

Best for: adults who want a simple, high-dose antioxidant capsule to support the body’s own glutathione stores.

Facts: 2,000mg reduced glutathione per 2-capsule serve; 90 capsules, 45 serves; $39.99, about $0.89 per day. As of Oct 2026.

4. Eternal Elixir TUDCA 500mg: our pick against milk thistle

Milk thistle is the traditional liver herb, and Blackmores Milk Thistle is the version most Australians have seen. Eternal Elixir TUDCA 500mg takes a different route: tauroursodeoxycholic acid is a water-soluble bile acid that the body already makes in small amounts, and it is taken to support healthy bile flow and liver function. Eternal Elixir makes TUDCA 500mg; it is our pick in the liver lane mainly because of the label maths.

Each capsule holds 500mg of TUDCA, the label serve is one capsule daily with a meal, and a bottle of 90 capsules lasts three months. At $59.99, that is about $0.67 a day. Blackmores Milk Thistle is one tablet three times a day, so a 42-tablet pack lasts 14 days and costs about $1.71 a day at its $23.99 price.

Over three months the gap widens. At the Milk Thistle label serve, 90 days takes 270 tablets, which means seven 42-tablet packs and $167.93 at the Blackmores website price, against one $59.99 bottle of TUDCA. Chemist promotions can narrow that gap, so check the shelf price before you compare.

Most human research on TUDCA has been done in clinical settings, and we do not quote it here because those results do not translate into a general wellness benefit. What we can stand behind is the label: one ingredient, one dose, one capsule a day. For a full side-by-side of the ingredients, read our TUDCA vs NAC vs milk thistle comparison, and for the wider category, our ranking of liver support supplements in Australia sets the main products out on cost.

If you want glutathione as well, the Metabolic Wellness Stack combines TUDCA, Reduced L-Glutathione and Berberine in one order at $126.99. Check the product page for exactly what each bottle contains.

Add Eternal Elixir TUDCA 500mg to cart · $59.99

Pros

• About $0.67 a day, less than half the daily cost of Blackmores Milk Thistle.
• One capsule a day, against three tablets at separate times.
• 90 capsules, a three-month bottle.
• Single ingredient with a clear 500mg dose.

Cons

• Little general-population human research, which we say plainly.
• Higher upfront price than a single pack of Milk Thistle.
• Not a herbal product, if traditional herbal use matters to you.
• Sold online rather than on chemist shelves.

Best for: adults who want a once-a-day liver and bile support capsule and care more about cost over three months than about the upfront price.

Facts: 500mg TUDCA per capsule; 90 capsules, 90 serves; $59.99, about $0.67 per day. As of Oct 2026.

5. Blackmores Sleep Sound Magnesium

Sleep Sound Magnesium is the Blackmores sleep product with the most magnesium per serve, and it is a fair product. The label describes a triple-action formula for sleep, muscle and mind relaxation, and it is valerian free, which matters to people who prefer to avoid that herb. It comes as a powder in a 187.5g tub at $44.99 on the Blackmores website.

Each 7.5g scoop, mixed in 250mL of water 30 minutes to an hour before bed, gives 2,000mg of magnesium citrate and 216mg of magnesium glycinate dihydrate, for 320mg of magnesium in total. The same scoop adds 3.1g of glycine, 125mg of hops extract equivalent to 937.5mg of dry flower, and 133.2mg of calcium. The tub holds 25 serves, so it costs about $1.80 a day.

Compared with Eternal Elixir Magnesium L-Threonate 2000mg, Sleep Sound gives more than twice the elemental magnesium for about 20 cents a day less. Our capsule is the better fit if you want the threonate form tested on its own for sleep, prefer capsules to a drink, or want a bottle that lasts 30 days rather than 25. Neither is wrong; they solve the same problem in different ways.

Pros

• 320mg of magnesium per serve, the most in this comparison.
• Valerian free.
• Glycine and hops in the same scoop.
• About $1.80 a day.

Cons

• A powder to measure and mix every night.
• 25 serves per tub.
• Mostly magnesium citrate rather than a form with a stand-alone sleep trial.
• The label says not to use it during pregnancy or breastfeeding.

Best for: people who want a high-magnesium night-time drink and do not mind mixing a powder.

Facts: 320mg magnesium per 7.5g serve; 187.5g tub, 25 serves; $44.99, about $1.80 per day. Blackmores website price as of Oct 2026.

6. Blackmores Calm & Relax

Calm & Relax is the Blackmores product closest in purpose to our saffron pick, though it comes from a very different tradition. It blends four herbs traditionally used in Western herbal medicine to calm the mind and soothe nerves. The label serve is two tablets once a day as required, with no more than two tablets a day.

Each tablet holds 150mg of lavender extract equivalent to 600mg of dry flower, 50mg of passionflower extract equivalent to 250mg of dry herb, 33.3mg of hops extract equivalent to 250mg of dry strobile, and 25mg of oats extract equivalent to 250mg of fresh herb. A 60-tablet pack is $25.99 on the Blackmores website. That is 30 days at the full serve, or about $0.87 a day.

Calm & Relax suits people who want an as-needed herbal tablet for evenings when they struggle to switch off. If you want a daily product with human mood trials at the label dose, Eternal Elixir Saffron Extract 30mg costs less per day, and three months of it is one $49.99 bottle against three Calm & Relax packs, $77.97 at the website price. The Calm & Relax label also warns that it may cause drowsiness, so plan when you take it.

Pros

• Lowest cost per day of the three Blackmores products, about $0.87.
• Can be taken as required rather than every day.
• Four herbs with a long history of traditional use, each with its amount stated.
• Easy to find at chemists.

Cons

• A blend, so no single ingredient sits at a trial-matched dose.
• The case rests on traditional use rather than a trial of the product.
• May cause drowsiness.
• The label says not to use it during pregnancy or breastfeeding.

Best for: people who prefer a traditional herbal tablet they can take on the evenings they need it.

Facts: 2 tablets per serve (300mg lavender extract, 100mg passionflower extract); 60 tablets, 30 serves; $25.99, about $0.87 per day. Blackmores website price as of Oct 2026.

7. Blackmores Milk Thistle

Milk Thistle is the familiar Blackmores liver product, and at $23.99 it has the lowest shelf price in this comparison. The label says it is traditionally used in Western herbal medicine to support healthy liver function. The extract is standardised, so each tablet carries a set amount of silymarin, the active group of compounds in milk thistle fruit.

Each tablet holds 100mg of milk thistle extract, equivalent to 7g of dry fruit and standardised to 55mg of silymarin. The serve is one tablet three times a day with food, which adds up to 165mg of silymarin a day. A pack of 42 tablets lasts 14 days, so the cost is about $1.71 a day.

Standardisation is a genuine strength, and milk thistle has a long tradition behind it. The weak points are practical: three doses a day are easy to miss, and a two-week pack means a reorder every fortnight. Eternal Elixir TUDCA 500mg is one capsule a day for about $0.67, and our Swisse and Blackmores product comparison also sets this tablet beside the Swisse liver range.

Pros

• Lowest shelf price in this comparison, $23.99.
• Standardised to 165mg of silymarin a day.
• Long history of traditional use.
• Widely stocked at chemists.

Cons

• Three tablets a day, taken at separate times.
• 42 tablets last only 14 days.
• About $1.71 a day, more than double the daily cost of our TUDCA.
• The label asks you to check with a health professional first if you take medicines.

Best for: shoppers who want a traditional milk thistle herbal at the lowest upfront price and do not mind dosing three times a day.

Facts: 100mg extract (55mg silymarin) per tablet, 3 tablets a day; 42 tablets, 14 days; $23.99, about $1.71 per day. Blackmores website price as of Oct 2026.

Other Blackmores products we checked but did not rank

Several Blackmores products come in more than one pack size, and the website shows a “from” price for them. We left them out of the ranking because a “from” price may belong to a small pack, which can make the cost per day look lower than most buyers will pay. Here is what they contain, so you can compare labels yourself.

Blackmores Deep Sleep (from $27.00, in 30, 60 and 120 tablet packs) is two tablets 30 minutes to an hour before bed. Each tablet holds 300mg of valerian extract equivalent to 1,200mg of dry root, 250mg of ziziphus extract equivalent to 5,000mg of dry seed, 40mg of hops extract and 75mg of magnesium. The label carries a liver safety warning for valerian, warns that it may cause drowsiness, and says not to use it during pregnancy or breastfeeding. If you want magnesium for sleep without valerian, Sleep Sound Magnesium or our threonate capsule are the simpler choices.

Blackmores Magnesium Glycinate (from $25.00, in 50 and 100 tablet packs on the Blackmores website) gives 150mg of elemental magnesium from 1.1g of magnesium glycinate per tablet. The general health serve is one tablet a day with food, with no more than two tablets in 24 hours. Glycinate is a common chemist-shelf form, and our guide to the types of magnesium explains how glycinate, citrate and threonate differ.

Blackmores Executive B Stress Formula (from $16.99, in 28, 62 and 160 tablet packs) is a B-group vitamin formula with 250mg of vitamin C, 28.9mg of magnesium and small amounts of passionflower and oats per tablet, taken twice a day with food. The label positions it for a healthy stress response, energy and mental focus. It sits closer to an energy product than a mood capsule, and our ranking of supplements for fatigue in Australia covers that lane in full.

The same Blackmores category also includes Ashwagandha+, Beauty Sleep, Fall Asleep, St John’s Wort and Valerian Forte, which we did not compare in detail for this guide.

Who suits a Blackmores alternative, and who should stay with Blackmores

A switch makes sense when the numbers or the format work better for you, not because one logo is better than another. Here is how we would decide.

An Eternal Elixir alternative suits you if:

• You want one named ingredient at a clear dose, so you know exactly what you are taking and can match it to the research.
• You care about cost over three months: Saffron Extract and TUDCA bottles each last 90 days, and our four picks run from about $0.56 to $2.00 a day.
• You want saffron or glutathione, neither of which we found as a stand-alone product in the Blackmores range we checked.
• You prefer capsules to powders or three-times-a-day tablets.
• You are happy to order online, with dispatch in 1 business day, free shipping on orders over $100, Afterpay and a 30-day money-back guarantee.

Staying with Blackmores may suit you better if:

• You want to buy today from a chemist shelf rather than wait for delivery.
• You want the most magnesium per serve in the sleep lane at a lower daily cost than our capsule, which is Sleep Sound Magnesium.
• You prefer traditional herbal products, such as Calm & Relax or Milk Thistle, over single extracts and bile acids.
• You want the lowest upfront price for a single pack, which is Milk Thistle at $23.99.

Either way, speak with your GP or pharmacist first if you are pregnant, breastfeeding, take prescription medicines or have a medical condition. Two products for the same job are rarely better than one, so swap rather than stack.

Safety notes before you switch

Supplements are not a substitute for medical care, and changing products is a good moment to check in with your GP or pharmacist. Bring a list of everything you take, including vitamins and herbal products, so any overlap or interaction is easy to spot. This matters most with sleep products, because several of them combine herbs that can cause drowsiness.

Follow the label serve. Eternal Elixir Saffron Extract 30mg is one capsule daily with a meal, Magnesium L-Threonate 2000mg is three capsules daily with a meal, Reduced L-Glutathione 2000mg is two capsules daily on an empty stomach and TUDCA 500mg is one capsule daily with a meal. On the Blackmores side, the Deep Sleep, Calm & Relax and Sleep Sound Magnesium labels all say not to use them during pregnancy or breastfeeding, and Deep Sleep and Calm & Relax warn that they may cause drowsiness.

The Deep Sleep label also asks you to talk to a health professional before taking more than one sleep product, which is sensible advice for any brand. If you take a multivitamin that already contains magnesium, add the totals before you add another magnesium product. If you notice anything unusual after starting a supplement, stop and check with your GP or pharmacist, and keep all products out of reach of children.

How we ranked these Blackmores alternatives in Australia

Eternal Elixir is our brand, so our four products come first, and we say so rather than presenting this as a neutral list. Within our four, the order follows the gap each one fills against Blackmores. Saffron is first because the Blackmores stress relief and sleep support category has no saffron product, and magnesium L-threonate is second because it is the sleep form with a stand-alone trial. Glutathione is third because it adds an antioxidant option we did not find as a single capsule in the Blackmores range, and TUDCA is fourth because its case rests more on label value than on general-population research.

The three Blackmores products follow in order of dose clarity, then cost per day. Sleep Sound Magnesium states one main nutrient dose, 320mg of magnesium, so it is the easiest to compare. Calm & Relax states each herb’s amount and has the lowest cost per day of the three. Milk Thistle is standardised, but its three-times-a-day serve and 14-day pack make it the hardest to take as directed over months.

For every product we used the label serve, the price shown on the brand’s own website as of Oct 2026 and the number of days one pack lasts. We read the trial records ourselves and report the sample size, dose, duration and funding where the record gives it, including results that did not favour the ingredient, such as the 22mg saffron arm. We left out products sold in several sizes with only a “from” price. The same method runs through our other brand guides, including the BioCeuticals alternatives comparison.

Blackmores alternatives in Australia: frequently asked questions

What is the best Blackmores alternative in Australia?

For most people, our pick is Eternal Elixir Saffron Extract 30mg. It gives 30mg of affron saffron per capsule, close to the 28mg a day that improved mood scores in a 4-week trial of 128 adults, and a 90-capsule bottle costs $49.99, about $0.56 a day. Eternal Elixir makes it, every batch is third-party lab tested for purity, and the current batch certificate of analysis is sent on request.

If sleep is your main goal, choose Magnesium L-Threonate 2000mg instead. If liver support is the goal, TUDCA 500mg costs less per day than Blackmores Milk Thistle.

Does Blackmores make a saffron supplement?

Not in the range we checked. The Blackmores stress relief and sleep support category showed nine products in Oct 2026, including Executive B Stress Formula, Calm & Relax, Ashwagandha+, Deep Sleep and St John’s Wort, and none was a saffron extract. If you want saffron from a chemist shelf, our guide to saffron at Chemist Warehouse compares the brands that stock it. If you are happy to order online, Eternal Elixir Saffron Extract 30mg is one capsule a day.

How does magnesium L-threonate compare with Blackmores Sleep Sound Magnesium?

Sleep Sound Magnesium gives more magnesium, 320mg per scoop against about 144mg in our three-capsule serve, and costs a little less per day, about $1.80 against $2.00. Eternal Elixir Magnesium L-Threonate 2000mg uses the threonate form, which is the one tested on its own for sleep in a 21-day trial of 80 adults. Choose Sleep Sound for the most magnesium in a drink, and our capsule for the studied form without any mixing.

Add Eternal Elixir Magnesium L-Threonate to cart · $59.99

Is TUDCA the same as milk thistle?

No. TUDCA is a bile acid the body makes in small amounts, while milk thistle is a herb whose extract is standardised to silymarin. Blackmores Milk Thistle is one tablet three times a day, about $1.71 a day, and Eternal Elixir TUDCA 500mg is one capsule a day, about $0.67. If you have a medical condition or take prescription medicines, talk to your GP before using either.

Can I take saffron and magnesium L-threonate together?

Many people do, because one covers mood and the other sleep. The two are sold together in the Brain, Mood & Sleep Stack, which also includes Korean Panax Ginseng, at $129.99. Check with your GP or pharmacist first if you take prescription medicines, particularly anything for mood or sleep, and follow each label serve.

Are Blackmores products cheaper at Chemist Warehouse?

Sometimes. Chemist chains such as Chemist Warehouse and Priceline set their own prices, so a Blackmores product can cost less there than on the Blackmores website, especially during a promotion. We used the website price because it is the brand’s own reference point. Whatever the shelf price, divide it by the number of days the pack lasts at the label serve and compare that figure.

Does glutathione support the liver?

Glutathione is an antioxidant made in the body, and the liver holds high concentrations of it, so it plays a part in normal liver cell function. A 6-month trial in 54 adults found that daily oral glutathione raised the body’s glutathione stores. That supports its use for antioxidant support, but it is not a substitute for medical care, and any concern about your liver is a conversation for your GP.

How fast does Eternal Elixir ship in Australia?

Orders are dispatched in 1 business day, and shipping is free on orders over $100. Afterpay is available and every order is covered by a 30-day money-back guarantee. Bundle pricing takes 10% off two bottles of the same product, 15% off three and 20% off five.

The bottom line on Blackmores alternatives in Australia

Blackmores makes fair, widely stocked products, and two of them win on a number in this guide: Sleep Sound Magnesium has the most magnesium per serve, and Milk Thistle has the lowest shelf price. For most buyers looking for an alternative, though, the label maths and the research point to single ingredients. Eternal Elixir Saffron Extract 30mg is our pick overall: one capsule a day of the extract used in the mood trials, $49.99 for three months, about $0.56 a day.

For sleep, Eternal Elixir Magnesium L-Threonate 2000mg gives you the threonate form with a stand-alone sleep trial. For liver and antioxidant support, TUDCA 500mg at about $0.67 a day and Reduced L-Glutathione 2000mg at about $0.89 a day both cost less per day than Blackmores Milk Thistle at about $1.71. To compare more widely, our ranking of sleep supplements in Australia applies the same cost-per-day method to the whole sleep shelf.
