Quick Answer
Hyaluronic acid supplements in Australia can modestly help skin hydration. The joint evidence is weaker. In small placebo-controlled trials, 120mg to 200mg of hyaluronic acid a day improved skin hydration and some wrinkle measures within four to 12 weeks. The longest joint trial found a benefit only in people aged 70 or younger who were also doing daily leg exercises. To choose a product, compare the dose per day, the source (fermented or rooster comb), whether the molecular weight is stated, and the cost per day. Our own Hyaluronic Acid 200mg is sold out and we don’t know when it will be back, so for skin our in-stock pick is Reduced L-Glutathione 2000mg, and for dry skin on the surface, our Grass-Fed Tallow Balm.
Eternal Elixir makes the products recommended on this page, so read this as our pick with the reasoning shown.
Hyaluronic acid supplements are sold in Australia as capsules, tablets, powders and drinks, and the ingredient also turns up in some collagen blends. This guide covers what the human trials found for skin hydration and for joint health, the doses they used, how to compare labels when you shop, and who should check with a doctor first. For a closer look at each skin trial, see our review of whether hyaluronic acid tablets work.
What Hyaluronic Acid Is and Why People Take It
Hyaluronic acid, also called hyaluronan, is a long sugar chain the body makes itself. It binds water and is found in skin, in the fluid that cushions joints, and in connective tissue. Skin holds about half of the body’s supply (Kawada et al., Nutrition Journal, 2014), and the amount in skin falls with age (Gao et al., 2023). On supplement labels it often appears as sodium hyaluronate, its salt form.
Serums and supplements take different routes. A serum draws water into the outer layers of skin within minutes and mainly acts there. A capsule is digested, and any effect builds slowly, which is why every trial below ran for at least four weeks. The idea behind supplements is that some of the molecule, or its fragments, reaches the skin and joints from the inside.
Benefits for Skin Hydration: What the Trials Found
Skin is where oral hyaluronic acid has the most human research. These four placebo-controlled trials are the ones most often cited:
| Trial | Who took part | Daily dose and length | What was found | Industry link |
|---|---|---|---|---|
| Oe, 2017 | 60 Japanese adults aged 22 to 59 with crow’s feet wrinkles | 120mg of a 2 kDa or a 300 kDa form, 12 weeks | The 300 kDa group had significantly fewer wrinkles than placebo from week 8 | Six of seven authors worked for Kewpie, which makes the hyaluronic acid tested |
| Hsu, 2021 | 40 healthy Asian adults aged 35 to 64 | 120mg, 12 weeks | Wrinkle scores, skin water content, water loss through the skin and elasticity all better than placebo | Three authors worked for Kewpie |
| Michelotti, 2021 | 60 women with mild to moderate signs of skin ageing | 200mg of a mixed molecular weight form, 28 days | In the hyaluronic acid group, hydration rose 10.6%, wrinkle depth fell 18.8%, wrinkle volume fell 17.6% and elasticity rose 5.1% | Run by a contract testing lab on a branded ingredient |
| Gao, 2023 | 129 women in Shanghai, in a younger (18 to 35) and an older (45 to 65) group | 100mg or 200mg of a 300 kDa form in a drink, 12 weeks | Better hydration from weeks 2 to 8 in both age groups, better skin tone from weeks 4 to 8, thicker outer skin layer at week 12 | Co-authored by staff of Bloomage, which supplied the drinks |
Read together, the trials point the same way: modest gains in skin hydration and some wrinkle measures after one to three months. Their weaknesses are just as consistent. They are small, most enrolled East Asian adults, and each one was run by, co-authored by or supplied by a company that sells hyaluronic acid. None of the four compared a capsule with a good moisturiser, which is the choice many shoppers are actually making.
Hyaluronic Acid for Joint Health: Weaker Evidence
The longest joint trial gave 60 adults with worn knee joints either 200mg of hyaluronic acid a day, as four 50mg capsules after breakfast, or a placebo for 12 months. Both groups also did daily thigh-strengthening exercises. Knee scores improved in both groups. The hyaluronic acid group did better only among people aged 70 or younger, and only at the two-month and four-month checks (Tashiro et al., The Scientific World Journal, 2012). Exercise was doing much of the work.
A 2016 review gathered the placebo-controlled knee trials published since 2008. They used 48mg to 240mg of hyaluronic acid a day for periods from two weeks to 12 months, and several tested mixtures in which other ingredients could have contributed (Oe et al., Nutrition Journal, 2016). Four of the review’s nine authors worked for Kewpie. Its authors read the results as positive, but the evidence base is small and largely industry-linked, so read joint claims on labels sceptically.
We don’t have an in-stock joint product, so we aren’t recommending one here. If your joints are painful, stiff or swollen, see your GP or a physiotherapist before spending money on supplements.
Does Oral Hyaluronic Acid Actually Get Absorbed?
It is a fair question, because hyaluronic acid is a large molecule and digestion breaks most food down. In studies where rats and dogs were fed radioactively labelled hyaluronic acid, some of the label turned up in skin tissue, and gut bacteria broke part of it down in the large intestine (reviewed in Kawada et al., 2014). Those are animal results. The human trials measured skin and joint outcomes, not absorption, so nobody yet knows how much reaches human skin.
How to Choose a Hyaluronic Acid Supplement in Australia
Most products are sold on hydration claims, so the label is where you compare them. These are the details worth checking:
| Label detail | What to look for | Why it matters |
|---|---|---|
| Dose per day | The amount of hyaluronic acid or sodium hyaluronate per daily serve | The skin trials used 100mg to 200mg a day, most often 120mg or 200mg |
| Source | “Fermentation” or “fermented” versus “rooster comb” or “chicken comb” | Fermented hyaluronic acid is animal-free. Rooster comb matters if you avoid animal products or are allergic to poultry |
| Molecular weight | A stated size in kDa, or “low” or “high” molecular weight | The trials used 2 kDa, 300 kDa and mixed forms. A stated size tells you what you are buying, though no trial we read showed one size clearly beating the rest |
| Other actives | Hyaluronic acid alone, or mixed with collagen, vitamin C and other ingredients | In a blend, check that the hyaluronic acid amount is listed on its own so you can compare it with the trial doses |
| Form | Capsule, tablet, powder or drink | No trial has compared forms. Gao 2023 used a drink and the others used capsules |
| Capsules per serve | How many capsules make up the daily dose | A bottle that needs several capsules a day runs out much sooner than its capsule count suggests |
| Cost per day | Price divided by the days of supply at the dose you will take | Bottle prices mislead when doses and capsule counts differ |
Search results for hyaluronic acid supplements in Australia are dominated by marketplace listings, including import resellers. On those, check that the listing states the dose per capsule, the source and the seller, and allow for shipping from overseas. Our comparison of hyaluronic acid supplements sold in Australia looks at individual products, and our guide to reading a supplement label covers fillers and dose tricks in general.
Who Might Consider It, and Who Should Check First
The skin trials enrolled adults with dry skin, visible wrinkles or mild to moderate signs of skin ageing, mostly aged from their 20s to their 60s. That is the group the evidence speaks to.
Side effects were uncommon. In the 12-month knee trial, four people taking hyaluronic acid dropped out over possible side effects (stomach discomfort in two, reflux in one, reduced appetite in one), against two on placebo who had skin irritation. The 2016 review reported no adverse events attributed to hyaluronic acid in the knee trials it covered.
Talk to your doctor or pharmacist first if you are pregnant or breastfeeding or take prescription medicines, and avoid rooster comb products if you are allergic to poultry. Our guide to hyaluronic acid side effects goes through the safety data in more detail.
How to Take Hyaluronic Acid
Follow the label of the product you buy and don’t exceed it. In the 12-month knee trial, people took their capsules once a day after breakfast. The skin trials measured changes in hydration from about two to four weeks and in wrinkles from about eight weeks, so give a product two to three months of daily use before judging it.
Oral hyaluronic acid and a topical moisturiser or serum work on different layers, so using both is fine. We found no interaction data between oral hyaluronic acid and common supplements such as NMN, resveratrol or glutathione in the trials we read. If you take prescription medicines, ask your pharmacist.
From Our Range: In-Stock Options for Skin
We don’t currently stock hyaluronic acid. Our Hyaluronic Acid 200mg capsules are sold out, and we’d rather say so than send you to a page you can’t buy from. This is what we do have for skin:
- Reduced L-Glutathione 2000mg: 90 capsules for $39.99. The label serve is two capsules a day on an empty stomach, which gives 45 serves at $0.89 a day. Glutathione is a different ingredient from hyaluronic acid, with its own small skin trial. In 60 women aged 20 to 50, 250mg a day for 12 weeks reduced wrinkles at some measured sites compared with placebo, and skin elasticity tended to improve (Weschawalit et al., 2017). That trial used a lower daily amount than our two-capsule serve. Our guide to glutathione for skin and longevity and our comparison of glutathione supplements in Australia set out the evidence and the alternatives.
- Grass-Fed Tallow Balm: a topical balm, not a supplement. It blends Australian pasture-raised tallow with beeswax, coconut oil and raw honey, and a 60g jar is $29.99. Use it to seal moisture into dry skin. Our guide to tallow and the skin barrier explains where it fits, and our tallow balm comparison sets it against other Australian balms.

What is the best form of hyaluronic acid supplement?
No trial has compared capsules, tablets, powders and drinks head to head. Most skin trials used capsules, and the largest used a powder dissolved in 200mL of water once a day. A label that states the dose, source and molecular weight tells you more than the form does, so choose the form you will take every day.
Is it a good idea to take hyaluronic acid supplements?
For skin, small trials found modest improvements in hydration and some wrinkle measures after one to three months at 120mg to 200mg a day, with few side effects. Most of those trials were tied to hyaluronic acid makers. For joints, the evidence is weaker. It is a reasonable thing to try for dry skin if the cost per day suits you, but it is no substitute for sunscreen and a moisturiser.
What are the best hyaluronic acid tablets?
Judge tablets and capsules the same way: the hyaluronic acid per daily serve (120mg to 200mg matches the trials), a stated source and molecular weight, few extra actives, and the cost per day. Our own hyaluronic acid capsules are out of stock. Our hyaluronic acid comparison lists products sold in Australia.
How long does oral hyaluronic acid take to work?
In the trials, skin hydration changed from about two to four weeks and wrinkle measures from about eight weeks. The 12-month knee trial saw differences at two and four months, and only in people aged 70 or younger. Give it two to three months of daily use before deciding.
How much hyaluronic acid should you take a day?
The skin trials used 100mg to 200mg a day, most often 120mg or 200mg. The knee trials in the 2016 review used 48mg to 240mg a day. Follow the label of your product and don’t exceed it.
Is oral hyaluronic acid better than a serum?
They do different jobs. A serum hydrates the outer skin within minutes. Oral hyaluronic acid produced slower changes in hydration and wrinkles over weeks in the trials. Using both is fine.
Is hyaluronic acid vegan?
Hyaluronic acid made by microbial fermentation is animal-free. Rooster comb hyaluronic acid is not. Check the capsule shell as well, since some are made from gelatine.
Are there side effects of hyaluronic acid supplements?
They were uncommon in the trials and mostly digestive: stomach discomfort, reflux and reduced appetite in a handful of people over 12 months. Talk to your doctor first if you are pregnant, breastfeeding or taking prescription medicines, and avoid rooster comb products if you are allergic to poultry.
The Bottom Line
Hyaluronic acid supplements in Australia rest on a small set of skin trials, nearly all tied to hyaluronic acid makers, that found modest hydration and wrinkle gains at 120mg to 200mg a day over one to three months. The joint evidence is weaker. When you shop, compare the daily dose, the source, the molecular weight and the cost per day. Our hyaluronic acid is sold out, so for skin our in-stock pick is Reduced L-Glutathione 2000mg, and for dry skin on the surface, our Grass-Fed Tallow Balm.
