Seeking Health Alternatives Australia 2026: TMG and Glutathione

Last updated: October 26, 2026 · By Eternal Elixir Editorial

Last updated: October 26, 2026 · By Eternal Elixir Editorial · 6 products compared

Seven hundred milligrams. That is how much TMG (trimethylglycine, also sold as betaine anhydrous) sits in one capsule of Seeking Health Homocysteine Nutrients, the only Seeking Health product sold in Australia that contains it. The published betaine trials started at 1,500 mg a day. That gap is the reason many Australians start looking for Seeking Health alternatives, and it is where this comparison begins.

Seeking Health is a methylation-focused brand from the United States, and Australians mostly buy it through online stockists such as Return2Health and iHerb. Its labels are detailed and its formulas use active vitamin forms, which is why it has a loyal following. The trade-off is price: imported practitioner formulas cost more per gram, and the single-ingredient options are limited. We read every relevant Seeking Health label and price on 26 October 2026 and set them against the Seeking Health alternatives you can order in Australia today.

Eternal Elixir makes two of the products on this list, and they are our picks. Every figure for the other products is taken from their own labels and retailer pages.

Seeking Health Alternatives Compared on Cost Per Day

The table ranks six products for the two jobs Seeking Health is best known for in Australia: methyl support with TMG, and glutathione. Price per day is the shelf price divided by the days a pack lasts at the label’s own serving. The last price column shows what you pay for each gram of the main ingredient, so a 700 mg capsule and a 2,000 mg serve can be compared fairly.

Prices read 26 October 2026 from eternalelixir.com.au and return2health.com.au, including GST. NOW Foods and Jarrow were on sale at the time (regular prices $40.57 and $76.79). S-acetyl and reduced glutathione are different molecules, so their per-gram prices are shown for reference rather than as a like-for-like comparison.

Where Australians Buy Seeking Health and What It Costs

Search for Seeking Health in Australia and the first page is almost entirely stockists: a trans-Tasman practitioner store, several iHerb category pages and individual Return2Health product pages. None of them line the products up against anything else, which is the gap this page fills.

We searched the Return2Health Seeking Health range on 26 October 2026 for every product overlapping the two ingredients Eternal Elixir sells in this area. Here is what the labels say:

• Homocysteine Nutrients (previously HomocysteX Plus, 60 capsules, $54.46): per capsule, 700 mg of TMG with riboflavin-5-phosphate 25 mg, P-5-P (vitamin B6) 15 mg, Quatrefolic® folate 1,360 mcg DFE and 1,000 mcg of vitamin B12 as methylcobalamin and adenosylcobalamin. Directions: one capsule with breakfast or early lunch, and not within five hours of bedtime.
• Glutathione with Cofactors Capsules (previously Optimal Glutathione Plus, 60 capsules, $101.21): 100 mg of S-acetyl-L-glutathione per capsule with riboflavin 5 mg, selenium 5 mcg and molybdenum 25 mcg. One capsule daily.
• Glutathione with Cofactors Lozenges (60 lozenges, $77.84): 25 mg of S-acetyl-L-glutathione per lozenge with smaller amounts of the same cofactors, sweetened with xylitol and monk fruit. One lozenge as needed, which works out at $1.30 a day.

Searches for a standalone Seeking Health TMG, nicotinamide riboside, magnesium L-threonate, berberine, resveratrol or saffron product at Return2Health returned none. In Australia, then, the brand’s TMG comes only inside a B-vitamin blend, and its glutathione comes only in the S-acetyl form at 25 to 100 mg per unit.

If you are weighing the brand against other names rather than one bottle, our guide to the top Australian supplement brands compares the local companies on range, sourcing and price.

TMG on Its Own or TMG in a B-Vitamin Blend

TMG is a methyl donor. Your body uses it to turn homocysteine back into methionine, a job that folate and vitamin B12 also do through a separate pathway. That is why Seeking Health pairs a modest amount of TMG with active B vitamins in Homocysteine Nutrients: the formula covers both routes in one capsule.

The question is how much TMG each route needs. The best-known dose study, published in The Journal of Nutrition by Olthof and colleagues in 2003, gave 76 healthy adults 1.5 g, 3 g or 6 g of betaine a day, or a placebo, for six weeks. Fasting plasma homocysteine fell by 12%, 15% and 20% respectively compared with placebo. Even the lowest dose in that trial is more than double the 700 mg in one Homocysteine Nutrients capsule.

So the two approaches suit different people. If you want the B vitamins and only a little extra TMG, a blend is tidy. If you want TMG in the range the trials used, a standalone product gets you there without doubling or tripling a multi-ingredient capsule, and without the higher B-vitamin intake that would come with it. Our plain-English explainer on trimethylglycine covers where TMG comes from in food, and the guide to lowering homocysteine naturally sets supplements alongside diet, alcohol and exercise.

#1. Eternal Elixir TMG 2000mg — Best for TMG at the dose range used in trials

Eternal Elixir TMG 2000mg is the simplest Seeking Health alternative for anyone who wants TMG itself rather than a blend. Each three-capsule serve gives 2,000 mg of betaine anhydrous, which sits between the 1.5 g and 3 g doses in the Olthof trial. The only other ingredients are rice flour and the vegetable capsule.

Key specs: 90 vegetable capsules per bottle, 3 capsules (2,000 mg) per serve, 30 serves, $44.99. That is $1.50 a day, or $0.75 per gram of TMG. Eternal Elixir ships from Sydney, and orders over $100 ship free. Every batch is third-party lab tested, and the batch Certificate of Analysis is available on request.

Against Homocysteine Nutrients, the daily cost is higher ($1.50 against $0.91) because you are getting nearly three times the TMG. Per gram of TMG, Eternal Elixir costs $0.75 against $1.30. The label suggests taking the three capsules with a meal, and most people pair them with breakfast. You can also split them across two meals.

Pros:

• 2,000 mg of TMG per serve, inside the range used in published betaine trials
• Single-ingredient formula, so it stacks with any B-vitamin product you already take
• Vegan capsules with no tablet binders or coatings
• Ships from Sydney, with free shipping over $100

Cons:

• Three capsules a day to reach the full serve
• No added B vitamins, so it does not replace a methylation blend if you want both
• Higher daily cost than a 700 mg blend capsule, because the dose is higher

Best for: Australians who want a meaningful dose of TMG on its own. View TMG 2000mg or read our TMG dosage guide before you start.

#2. Eternal Elixir Reduced L-Glutathione 2000mg — Best for the lowest daily glutathione cost

Eternal Elixir Reduced L-Glutathione 2000mg is the glutathione pick among Seeking Health alternatives. It uses reduced glutathione (GSH), the form the body uses directly, at 2,000 mg per two-capsule serve. A 90-capsule bottle gives 45 serves for $39.99, so each day costs $0.89 and each gram of glutathione costs $0.44.

Key specs: 90 capsules, 2 capsules (2,000 mg) per serve, 45 serves, $39.99. The label suggests taking the two capsules on an empty stomach, usually first thing in the morning. Every batch is third-party lab tested, with the Certificate of Analysis available on request.

Reduced glutathione has the clearest human trial behind it among the forms here. A six-month randomised controlled trial by Richie and colleagues, published in the European Journal of Nutrition in 2015, gave 54 non-smoking adults 250 mg or 1,000 mg of oral glutathione a day or a placebo. Glutathione levels in blood rose at both doses, and at six months the higher dose group showed increases of 30 to 35% in red blood cells, plasma and lymphocytes. Levels returned to baseline within a month of stopping.

Seeking Health’s capsule costs $1.69 a day for 100 mg of S-acetyl glutathione. Eternal Elixir costs $0.89 a day for 2,000 mg of reduced glutathione. The forms differ, as the section below explains, but on price per day this is the lowest in the comparison.

Pros:

• Lowest daily cost and lowest cost per gram of glutathione in this comparison
• 2,000 mg per serve, above the 1,000 mg dose used in the six-month trial
• 45 serves per bottle, so one bottle lasts six weeks
• Third-party lab tested, COA on request

Cons:

• Two capsules per serve, best taken away from food
• No added cofactors such as selenium or riboflavin

Best for: anyone comparing Seeking Health glutathione on value. Order Reduced L-Glutathione 2000mg, or check our glutathione dosage guide for how people split the serve.

#3. Seeking Health Homocysteine Nutrients — Best for TMG with active B vitamins in one capsule

Seeking Health Homocysteine Nutrients is the product most people mean when they search for Seeking Health in a methylation context. It was previously sold as HomocysteX Plus. One capsule gives 700 mg of TMG with riboflavin-5-phosphate, P-5-P, Quatrefolic® folate and two active forms of vitamin B12.

Key specs: 60 capsules, 1 capsule per serve, $54.46 at Return2Health on 26 October 2026. That is $0.91 a day, or $1.30 per gram of TMG. The label asks you to take it with breakfast or an early lunch and to avoid it within five hours of bedtime.

The appeal is convenience. If your goal is a full set of active B vitamins plus some TMG, this capsule does both. The limit is the TMG dose: matching the 2,000 mg in one Eternal Elixir serve would take about three capsules, which would also triple the B vitamins and cost about $2.72 a day. Do not take more than the label serving without advice from your doctor or pharmacist.

Pros:

• Active B vitamins and TMG in a single capsule
• Clear, detailed label with named branded ingredients
• One capsule a day

Cons:

• 700 mg of TMG, below the lowest dose in the Olthof trial
• $1.30 per gram of TMG, against $0.75 for Eternal Elixir
• Imported and sold through stockists, so the price varies by store

Best for: people who want an all-in-one B-vitamin and TMG capsule and are happy with a lower TMG dose.

#4. Seeking Health Glutathione with Cofactors Capsules — Best for S-acetyl glutathione with cofactors

Seeking Health Glutathione with Cofactors Capsules (previously Optimal Glutathione Plus) take a different route from the reduced glutathione products here. Each capsule holds 100 mg of S-acetyl-L-glutathione (the Emothion® ingredient) with riboflavin 5 mg, selenium 5 mcg and molybdenum 25 mcg, nutrients the label describes as supporting the body’s own glutathione recycling.

Key specs: 60 capsules, 1 capsule daily with or without food, $101.21 at Return2Health. That is $1.69 a day. The lozenge version costs $77.84 for 60 lozenges at 25 mg each, or $1.30 a day.

S-acetyl glutathione carries an acetyl group on the sulfur atom, which is intended to help it survive digestion before cells remove the acetyl group. Brands use that to justify a lower milligram dose. It is a reasonable idea, but there is far less published human research on S-acetyl glutathione supplements than on reduced glutathione, so the lower dose is a bet on the chemistry rather than on a matched trial.

Pros:

• One small capsule a day
• Includes riboflavin, selenium and molybdenum
• Lozenge option for people who dislike capsules

Cons:

• Highest daily cost in this comparison at $1.69
• 100 mg per capsule, a small fraction of the doses used in reduced glutathione trials
• Limited human research on the S-acetyl form as a supplement

Best for: shoppers who specifically want the S-acetyl form with cofactors and accept the higher price.

#5. NOW Foods TMG 1000mg — Best for the lowest price per gram of TMG

NOW Foods TMG 1000mg is the cheapest way to buy TMG by the gram in this comparison, and it deserves that label. Each tablet holds 1,000 mg of betaine anhydrous. A bottle of 100 tablets cost $34.49 at Return2Health on 26 October 2026, down from a regular $40.57.

Key specs: 100 tablets, label serving 3 tablets (3,000 mg), directions of one to three tablets twice daily with food. At the label serving a bottle gives 33 days and costs $1.03 a day. If you take 2,000 mg a day to match one Eternal Elixir serve, it costs about $0.69 a day. That is $0.34 per gram of TMG, the lowest in the list.

The trade-offs are format and source. These are pressed tablets with cellulose binders and a coating, and the product is imported from the United States, so stock and price move with the stockist. Eternal Elixir TMG costs more per gram but comes as vegan capsules shipped from Sydney. If price per gram is your only test, NOW Foods wins it.

Pros:

• Lowest price per gram of TMG in this comparison
• Flexible 1,000 mg tablets for building your own dose
• Widely stocked by Australian online stores

Cons:

• Large tablets with binders and a coating
• Label directions run to six tablets a day, well above the 2,000 mg most people start with
• Imported, with sale prices that vary by store

Best for: budget-first buyers who are comfortable with tablets. Our roundup of the TMG supplements sold in Australia covers more options on cost.

#6. Jarrow Formulas Reduced Glutathione 500mg — Best for a single 500 mg reduced glutathione capsule

Jarrow Formulas Reduced Glutathione 500mg is a straightforward reduced glutathione capsule from another long-running US brand. One capsule gives 500 mg, and the label says to take one a day with a meal.

Key specs: 60 capsules for $61.44 (sale price, regular $76.79), or 120 capsules for $110.86. At one capsule a day the 60-capsule bottle costs $1.02 a day, which is $2.05 per gram of glutathione. Jarrow also sells an S-acetyl glutathione 100 mg tablet at the same $61.44 for 60.

Jarrow sits between the two Seeking Health glutathione products and Eternal Elixir on price per day. Per gram, it costs more than four times as much as Eternal Elixir Reduced L-Glutathione.

Pros:

• One capsule a day at 500 mg
• Reduced glutathione, the form used in the six-month trial
• Larger 120-capsule bottle lowers the per-day cost slightly

Cons:

• $2.05 per gram, against $0.44 for Eternal Elixir
• Half the 1,000 mg dose that showed the larger changes in the Richie trial
• The listed price was a sale price at the time of checking

Best for: people who want one 500 mg capsule and already trust the Jarrow brand. Our full comparison of glutathione supplements in Australia covers liposomal and powder formats as well.

Reduced Glutathione vs S-Acetyl Glutathione: Reading the Labels

The glutathione half of this comparison mixes two molecules, so it helps to read the labels side by side. Reduced glutathione (GSH) is the form found in your cells. S-acetyl glutathione is the same molecule with an acetyl group attached, which manufacturers say protects it in the gut.

Here is how the four glutathione products in this guide compare once you line them up:

• Eternal Elixir Reduced L-Glutathione: reduced form, 2,000 mg per serve, $0.89 a day.
• Jarrow Reduced Glutathione: reduced form, 500 mg per capsule, $1.02 a day.
• Seeking Health capsules: S-acetyl form, 100 mg per capsule plus cofactors, $1.69 a day.
• Seeking Health lozenges: S-acetyl form, 25 mg per lozenge plus cofactors, $1.30 a day.

The published six-month trial cited above used 250 mg and 1,000 mg of oral glutathione a day. Both reduced-form products here meet or exceed the lower dose with a single serve. The S-acetyl products work on a different premise, and no trial we found compares 100 mg of S-acetyl glutathione with 1,000 mg of reduced glutathione head to head. If you are unsure, the reduced form has the longer research record. For timing questions, see how long glutathione takes to work.

How We Evaluated These Seeking Health Alternatives

We did not test these products in a lab. Every figure comes from the product label, the seller’s page or a published study, read on 26 October 2026. We scored each product on five criteria:

• Dose against the research (30%): how the daily serve compares with doses used in published human trials.
• Australian availability and shipping (20%): whether it can be ordered from an Australian store and how it ships.
• Price per day and per gram in AUD (20%): calculated from the label serving and the live shelf price.
• Formula clarity (15%): a full label with named forms and amounts, and no undisclosed blends.
• Range for stacking (15%): whether the brand sells related single ingredients you can combine.

Eternal Elixir ranks first and second because its products carry the highest dose per serve among the capsules here and the lowest glutathione cost per day. NOW Foods keeps its true label as the lowest price per gram of TMG. We do not call this list independent, since we make two of the products, so every competitor figure is shown in full for you to check.

Seeking Health Alternatives: Frequently Asked Questions

Which Seeking Health alternative should I choose for TMG?

Eternal Elixir TMG 2000mg is our pick. One three-capsule serve gives 2,000 mg of TMG, close to three times the 700 mg in a Seeking Health Homocysteine Nutrients capsule, and it costs $0.75 per gram of TMG against $1.30. If the lowest price per gram matters most, NOW Foods TMG tablets cost $0.34 per gram.

Does Seeking Health sell a standalone TMG supplement in Australia?

Not at Return2Health when we checked on 26 October 2026. The only Seeking Health product there containing TMG was Homocysteine Nutrients, which combines 700 mg of TMG with active B vitamins in each capsule.

Is S-acetyl glutathione better than reduced glutathione?

Not proven either way. S-acetyl glutathione is designed to survive digestion, which is why it is sold at lower doses such as 100 mg. Reduced glutathione has more human research, including a six-month randomised trial in which 250 mg and 1,000 mg a day raised glutathione levels in blood.

How much does Seeking Health glutathione cost per day in Australia?

Glutathione with Cofactors capsules cost $101.21 for 60 at Return2Health, or $1.69 a day at one capsule. The lozenges cost $77.84 for 60, or $1.30 a day. Eternal Elixir Reduced L-Glutathione 2000mg costs $0.89 a day.

Where can I buy Seeking Health in Australia?

Seeking Health is sold through online stockists such as Return2Health and iHerb’s Australian site, and through some practitioners. Prices differ between stores, so check the current price and the shipping cost before you compare.

Is Seeking Health a good brand?

Its labels are detailed and use active vitamin forms with named branded ingredients, which many practitioners value. The trade-offs for Australian buyers are price per gram, import stock and a narrow single-ingredient range. Judge each product on its label dose and cost per day rather than on the brand name.

Can I take TMG and glutathione together?

Yes, many people take both. TMG supports methylation and glutathione is an antioxidant, so they do different jobs. Take TMG with a meal and glutathione on an empty stomach, as each label suggests. Check with your doctor or pharmacist first if you take medication or are pregnant.

Do I still need TMG if I take a B-vitamin complex?

Not necessarily. Folate, B12 and TMG all help recycle homocysteine, through different pathways. Some people use a B-vitamin product alone, and others add TMG for a second route. Our guide to betaine anhydrous, TMG and betaine HCl explains which form does what.

Verdict: Which Seeking Health Alternative to Buy in Australia

For most Australians comparing Seeking Health, the choice comes down to which ingredient you are actually shopping for.

• You want TMG at a trial-level dose: Eternal Elixir TMG 2000mg. It gives 2,000 mg per serve in vegan capsules, ships from Sydney and costs $0.75 per gram.
• You want glutathione on value: Eternal Elixir Reduced L-Glutathione 2000mg, at $0.89 a day and $0.44 per gram, the lowest in this comparison.
• You want active B vitamins and a little TMG in one capsule: Seeking Health Homocysteine Nutrients does that job well.
• You only care about price per gram of TMG: NOW Foods TMG 1000mg tablets.

Many readers end up pairing the two Eternal Elixir products: TMG with breakfast and glutathione before it. Together they cost $2.39 a day. If you are comparing other overseas practitioner brands too, our Thorne alternatives comparison and Herbs of Gold alternatives guide use the same cost-per-day method.
