Quick Answer
Do hyaluronic acid tablets work? For skin, probably a little. In small placebo-controlled trials, 120mg to 200mg of hyaluronic acid a day improved skin hydration and some wrinkle measures over four to 12 weeks. Most of those trials were run or funded by companies that make hyaluronic acid. For joints the evidence is thinner: one 12-month trial found a benefit only in people aged 70 or younger. Our own Hyaluronic Acid 200mg is out of stock, and we don’t know when it will be back. For skin, our in-stock pick is Reduced L-Glutathione 2000mg, a different ingredient with its own skin trial, 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 working shown.

Hyaluronic acid supplements promise from the inside what serums do from the outside. This guide looks at what swallowing hyaluronic acid actually does, trial by trial, for skin and for joints. It also covers how tablets compare with serums and fillers, what to look for on the label (including rooster comb versus fermented sources), how much to take, and who should check with a doctor first.
What Hyaluronic Acid Does in the Body
Hyaluronic acid, also called hyaluronan, is a long sugar chain your body makes itself. It holds water and gives tissues their cushioning. It is found in skin, in the fluid that lubricates joints, in the eyes and in connective tissue, and skin holds about half of the body’s supply (Kawada et al., Nutrition Journal, 2014).
Serums put it on the surface of the skin, where it draws water into the outer layers. Fillers inject it where a clinician wants volume. Tablets and capsules take a different route: they are swallowed and digested, and the question is whether enough of the molecule, or its fragments, reaches skin and joints to make a difference.
Do Hyaluronic Acid Tablets Work for Skin?
Oral hyaluronic acid has more human trials for skin than for anything else. These are the main ones:
| Trial | Who took part | Daily dose and length | What changed compared with placebo | Who ran or funded it |
|---|---|---|---|---|
| Oe, 2017 | 60 Japanese adults aged 22 to 59 with crow’s feet wrinkles | 120mg, 12 weeks | Fewer wrinkles in one of the two hyaluronic acid groups from week 8 | Most authors employed by Kewpie, a hyaluronic acid maker |
| Hsu, 2021 | 40 healthy Asian adults aged 35 to 64 | 120mg, 12 weeks | Better wrinkle scores, skin water content, water loss and elasticity | Three authors employed by Kewpie |
| Michelotti, 2021 | 60 women with mild to moderate signs of skin ageing | 200mg, 28 days | Hydration up 10.6%, wrinkle depth down 18.8%, wrinkle volume down 17.6%, elasticity up 5.1% | Run by a contract testing lab on a branded ingredient |
| Gao, 2023 | 129 Chinese women, younger and older groups | 100mg or 200mg in a drink, 12 weeks | Better hydration from weeks 2 to 8, skin tone from weeks 4 to 8, thicker outer skin at 12 weeks | Co-authored by staff of Bloomage, which supplied the drink |
Read together, these trials point the same way: modest improvements in skin hydration and some wrinkle measures after one to three months. Their limits are real. They are small, most were in East Asian adults, and every one was run by, co-authored by or supplied by a company that sells hyaluronic acid. The 2014 review that summarised the earlier Japanese dry-skin trials came from Kewpie researchers too (Kawada et al., 2014).
How it works in people isn’t settled. Animal studies suggest fragments are absorbed and reach the skin, and cell studies suggest they signal skin cells to make more of their own hyaluronic acid. The human trials measured skin outcomes, not those steps.
If skin is your goal and you’d like an in-stock option from us, our Reduced L-Glutathione 2000mg is a different ingredient with its own trial: in 60 women aged 20 to 50, 250mg a day for 12 weeks lowered wrinkles at some measured sites compared with placebo, and skin elasticity tended to improve (Weschawalit et al., 2017). Our guide to glutathione for skin, immunity and longevity sets out that evidence and its limits.

The best-known joint trial gave 60 adults with knee joint wear 200mg of hyaluronic acid a day, or a placebo, for 12 months, along with 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 second and fourth months (Tashiro et al., The Scientific World Journal, 2012). That is a weak and mixed result, and exercise was doing much of the work.
We don’t have an in-stock product for joints, so we aren’t recommending one here. If your joints are painful, stiff or swollen, see your GP or a physiotherapist.
Hyaluronic Acid Tablets vs Serums vs Fillers
- Serums and creams work on the surface. They draw water into the outer skin within minutes and work best with a moisturiser on top.
- Tablets and capsules work slowly, if at all, over weeks to months, and the trials above measured changes in hydration and wrinkles, not volume.
- Fillers are injected by a clinician to add volume in a specific spot. They act immediately, last months, and carry their own risks such as bruising, swelling and, rarely, blocked blood vessels.

Rooster Comb or Fermented: What to Look for in a Hyaluronic Acid Supplement
Hyaluronic acid for supplements comes from two sources: chicken (rooster) combs, which are naturally rich in it, and microbial fermentation. Production has shifted towards fermentation because it is cheaper to make in bulk (Kawada et al., 2014). That matters if you avoid animal products or have a poultry allergy, so check the label for the source. If a label doesn’t state the source, ask the seller before you buy.
Other things worth checking on the label:
- Dose per day. The skin trials used 100mg to 200mg a day, and most used 120mg or 200mg.
- Molecular weight. Some labels state it. The Oe trial tested two sizes, and both helped, so a stated weight is useful information but not a guarantee.
- Other ingredients. Many “skin” formulas mix hyaluronic acid with collagen, vitamin C or other actives, often at lower hyaluronic acid doses than the trials.
- Cost per day. Compare the price of a day’s dose, not the price of the bottle.

Drinking Hyaluronic Acid vs Taking Tablets
Hyaluronic acid is also sold as powders and drinks. The largest trial above, Gao 2023, used a powder dissolved in 200mL of water once a day, and the others used capsules. We found no trial comparing drinks with tablets, so choose the form you’ll take every day.
How Much Hyaluronic Acid to Take, and When
The skin trials used 120mg to 200mg a day, and the joint trial used 200mg a day. People in the 12-month joint trial took their capsules after breakfast, and the Oe trial found no adverse events at 120mg a day. Follow the label on the product you buy. Trials measured changes from four weeks onwards, so give it at least two to three months before deciding whether it helps.
Side Effects and Who Should Check First
Oral hyaluronic acid caused few side effects in the trials. In the 12-month joint trial, four people on hyaluronic acid left over possible side effects (stomach discomfort in two, reflux in one and reduced appetite in one), against two on placebo with skin irritation. The two 12-week Kewpie skin trials reported no adverse events linked to hyaluronic acid.
Check with your doctor first if you are pregnant or breastfeeding, having cancer treatment, taking prescription medicines, or allergic to poultry (for rooster comb products). Our guide to hyaluronic acid side effects covers each trial and the difference between tablets, serums and fillers in detail.
From Our Range: In-Stock Options for Skin
Our Hyaluronic Acid 200mg capsules are out of stock, and we’d rather tell you that than send you to a page you can’t buy from. Here is what we do have for skin:
- Reduced L-Glutathione 2000mg: 90 capsules for $39.99, two capsules a day on an empty stomach, which is $0.89 a day. It is a different ingredient from hyaluronic acid, and its skin evidence is summarised above.

Is it good to take hyaluronic acid supplements?
For skin, small trials suggest a modest benefit to 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 run or funded by hyaluronic acid makers. For joints, the evidence is weak.
Do hyaluronic acid tablets actually absorb, or does your stomach destroy them?
Much of it is broken down, but animal studies suggest some fragments are absorbed and reach the skin. The human trials measured skin outcomes rather than absorption itself, and those outcomes did improve modestly.
How long do hyaluronic acid tablets take to work for skin?
Changes appeared from about two to four weeks for hydration and from about eight weeks for wrinkles in the trials. Give it two to three months before judging it.
Which food is high in hyaluronic acid?
Chicken combs are one of the richest known sources, which is why they are also used to make supplements. Animal connective tissue contains it too. We found no reliable data on how much hyaluronic acid from food reaches your skin.
What are the side effects of taking hyaluronic acid orally?
In the trials they were uncommon and mostly digestive: stomach discomfort, reflux and reduced appetite in a handful of people over 12 months. Check with your doctor first if you are pregnant, breastfeeding, having cancer treatment or taking prescription medicines.
Is hyaluronic acid vegan?
Fermented hyaluronic acid (often listed as sodium hyaluronate from fermentation) is suitable for vegans. Rooster comb hyaluronic acid is not. Check the capsule shell as well.
Can hyaluronic acid help with joint pain?
The evidence is weak. In a 12-month trial with daily exercise, 200mg a day helped only people aged 70 or younger, and only at some time points. See your GP or a physiotherapist about painful joints.
How does oral hyaluronic acid compare to fillers?
Fillers add volume in one spot straight away and are given by a clinician. Tablets work slowly, if at all, on overall skin hydration and fine lines, and don’t add volume.
What is the best hyaluronic acid supplement in Australia?
Our own Hyaluronic Acid 200mg is out of stock, so we aren’t naming a best one today. Look for 120mg to 200mg a day, a stated source (fermented or rooster comb) and a fair cost per day. If you want an in-stock skin supplement from us, our pick is Eternal Elixir Reduced L-Glutathione 2000mg at $0.89 a day. Eternal Elixir makes it.

The Bottom Line
Hyaluronic acid tablets have a small but consistent body of skin trials: 120mg to 200mg a day improved hydration and some wrinkle measures over one to three months, with few side effects, though almost every trial was tied to a hyaluronic acid maker. The joint evidence is weak. Our hyaluronic acid is out of stock, so for skin our in-stock pick is Reduced L-Glutathione 2000mg, and for dry skin on the surface our Grass-Fed Tallow Balm.
