Hyaluronic Acid: What's the Right Daily Dose?

There is no officially recommended daily dose of oral hyaluronic acid. What exists are doses that clinical trials have tested: in a randomised, double-blind, placebo-controlled trial in 150 healthy Caucasian adults, 120 mg per day of sodium hyaluronate for 12 weeks improved skin hydration and elasticity and reduced transepidermal water loss compared with placebo, with similar but more modest effects at 60 mg per day ¹. A meta-analysis of 7 randomised controlled trials on oral hyaluronic acid found statistically significant improvements in hydration, elasticity and wrinkle depth, although the studies are few and heterogeneous ².

So the honest answer is that, in the available evidence, the doses tested sit between 60 mg and 120 mg per day — and that the dose you should follow is the one on the label of the product you choose, not an invented number. Gummies for Skin Hydration and Firmness provide 130 mg of hyaluronic acid per 2-gummy serving, a dose slightly above the studied range. Study doses are not dosing instructions.

If you are thinking of taking more than the label indicates, ask yourself why. If it is because you think it will work better, the available evidence does not support that idea: there are no studies showing a benefit from exceeding the tested doses, and very high doses can cause gastrointestinal discomfort in some people. If it is because the product you bought has a low dose, it may make more sense to choose another with a dose within the studied range than to double your intake on your own.

Why is there no official daily dose?

Dietary reference values (DRVs) exist for vitamins and minerals with authorised health claims in the European Union ³. Hyaluronic acid is neither a vitamin nor a mineral: it is a polysaccharide that the body produces naturally, so there is no official reference value and no percentage of the DRV on the label. When you see "DRV not established" on a pack, that is exactly what it means — there is no official value to compare against.

Without a reference value, the only possible anchor is the doses used in research. And those vary: 60 mg and 120 mg per day in the 12-week trial in healthy adults ¹, and varied doses across the 7 trials included in the meta-analysis ². The dose is not a universal constant; it is a range that research has been exploring.

What the trials actually tested

It is worth looking at the numbers with context, because "120 mg" on its own says nothing about who, for how long and with what result.

Study	Population	Dose tested	Duration	Main result
Randomised, double-blind, placebo-controlled trial 1	150 healthy adults	60 mg/day or 120 mg/day of sodium hyaluronate	12 weeks	120 mg/day improved hydration and elasticity and reduced transepidermal water loss; 60 mg/day had similar but more modest effects
Meta-analysis of 7 randomised controlled trials 2	Adults, trials with oral hyaluronic acid supplementation	Varied doses between studies	Variable	Significant improvements in hydration, elasticity and wrinkle depth; firmness, wrinkle volume and transepidermal water loss without statistical significance

Notice what the table does not say: there is no 500 mg arm, nor a study showing that more is better. The dose-response relationship that exists is between 60 mg and 120 mg — above that, the evidence does not follow.

What the TuttiBear gummy label says

Gummies for Skin Hydration and Firmness state, in the directions for use, to chew 2 gummies per day, preferably after a meal. Each 2-gummy serving provides 130 mg of hyaluronic acid, plus 50 mg of vitamin C (62.5% of the DRV) and 16 mg of niacin (100% of the DRV). The pack contains 60 gummies, that is, 30 servings.

The comparison with the evidence is indirect: the trials used 60 mg and 120 mg per day ¹; the Gummies provide 130 mg per 2-gummy serving, a dose not tested in the trials. That is not a promise of a result, it is just a note of context. Study doses are not dosing instructions, and the dose you should follow is the one on the label.

On vitamin C: the authorised claim in the EU is that "vitamin C contributes to the normal function of the immune system" and "contributes to normal collagen formation for the normal function of skin" ³. If you want to understand this vitamin's role better, see how vitamin C works.

How to read the label without getting it wrong

The most common mistake is confusing the value per gummy with the value per serving. A serving can be 1, 2 or 3 gummies, and the number that matters for the daily dose is the one for the serving, not the unit.

• Check the serving: if the label says "per 2 gummies", the value shown corresponds to 2 gummies, not 1.
• Do not invent your dose: following more than indicated has no support in the evidence and is not a way to get more effect.
• Ignore the DRV percentage for hyaluronic acid: there is no reference value, so there is no percentage to calculate.
• Read the product as a whole: if you already take a multivitamin with vitamin C, check for overlap before adding supplements together.

If your doubt is between formats, it is worth reading hyaluronic acid gummies or tablets — there are no studies directly comparing the two formats, but there are practical differences that matter.

Does it make sense to split the dose across the day?

There is no evidence answering this question for oral hyaluronic acid. The trials that showed effects administered the dose once a day, for 12 weeks ¹, and the meta-analysis did not analyse split-dose schedules ².

What is known is that hyaluronic acid is a large molecule and that the fraction absorbed after ingestion is limited. There are no data indicating that splitting the dose improves absorption or effect. If your product indicates one daily intake, that is the reference to follow.

It is worth remembering that hyaluronic acid is not a vitamin the body cannot produce: it is present in foods such as bone broth, cartilage and cuts of meat with connective tissue, and a varied diet provides the precursors the body uses to synthesise it. The supplement is a complement, not a substitute — it serves to fill a gap when the diet is not enough or when natural production declines with age. If your diet is low in protein and vegetables, start there: a supplement does not compensate for an unbalanced diet.

How long until you notice something?

In the trials, effects were assessed over weeks, not days. The trial in 150 healthy Caucasian adults measured skin parameters monthly for 12 weeks ¹, and the meta-analysis pooled studies with variable durations ². There is no guaranteed timeframe for feeling a difference — and objective skin assessment in a study setting is not the same as subjective perception in everyday life.

This means that deciding "it doesn't work" after a week has no basis. But it also means that, if after a few months you notice nothing, it may simply be an ingredient that makes no difference to you.

More is not better: what is known about high doses

The available evidence does not show a benefit from exceeding the studied doses. In the 12-week trial, the 120 mg per day dose produced clearer effects than 60 mg, but there were no arms with much higher doses ¹. The meta-analysis also did not identify a threshold above which there was additional gain ².

In addition, most studies on hyaluronic acid use the injectable form — intra-articular, in a medical setting — and not the oral form. Those studies should not be used to draw conclusions about oral supplements: they are different routes of administration, different populations (often people with knee osteoarthritis) and different clinical contexts. For a more detailed analysis of what it does and does not do, see how hyaluronic acid works.

Side effects and safety

In the trial with oral supplementation in healthy Caucasian adults, hyaluronic acid was generally well tolerated ¹. Even so, the label warnings for Gummies for Skin Hydration and Firmness are clear: do not exceed the recommended daily dose; food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle; keep out of reach of children; in case of pregnancy, breastfeeding, illness or medication, consult a health professional before use; contains polyols and excessive consumption may have a laxative effect.

If you are thinking of giving a hyaluronic acid supplement to a child, do not decide the dose on your own: speak to a doctor or pharmacist first. The available trials do not cover children, so there are no data that allow an adequate dose to be established for this age group.

When to talk to a health professional

There are situations in which the dose should not be decided by you: pregnancy, breastfeeding, a diagnosed illness, taking regular medication or intending to give supplements to children. In these cases, speak to a doctor or pharmacist before starting. Not because hyaluronic acid is problematic, but because the available trials do not cover these populations, so safety in these groups is not established ¹.

If you have a diagnosed skin or joint condition, the conversation is even more important: oral supplementation does not replace clinical care, and what is known about oral hyaluronic acid comes from studies in healthy adults, not in patients.

In summary

The daily dose of hyaluronic acid has no official value. The available evidence points to 60 to 120 mg per day in 12-week trials in healthy Caucasian adults ¹, with significant improvements in hydration, elasticity and wrinkle depth in a meta-analysis of 7 trials with variable durations ². Gummies for Skin Hydration and Firmness provide 130 mg per 2-gummy serving, a dose slightly above the studied range. Follow the label, do not invent doses, give your body time and, if you have doubts or health conditions, speak to a professional. To know when to take it, see hyaluronic acid: when to take it?

Frequently asked questions

What is the recommended daily dose of hyaluronic acid?

There is no officially recommended daily dose. In clinical trials, the doses tested typically sit between 60 mg and 120 mg per day, for 12 weeks. The dose you should follow is the one indicated on the label of the product you choose.

Can I take more than the label dose to get more effect?

The available evidence does not show a benefit from exceeding the studied doses. In the 12-week trial, 120 mg per day had clearer effects than 60 mg, but there were no arms with much higher doses. More is not necessarily better.

How long does it take to notice an effect?

The trials assessed effects over weeks, not days — the main study measured skin parameters monthly for 12 weeks. There is no guaranteed timeframe, and individual perception can vary.

Is oral hyaluronic acid safe?

In the trial in healthy Caucasian adults, it was generally well tolerated. Gummies for Skin Hydration and Firmness contain polyols, and excessive consumption may have a laxative effect. In case of pregnancy, breastfeeding, illness or medication, consult a health professional.

Does the DRV percentage on the hyaluronic acid label mean anything?

No. Hyaluronic acid has no official reference value in the European Union, unlike vitamins and minerals. When the label says "DRV not established", it means there is no official value to compare against.

Can I take hyaluronic acid in gummies instead of tablets?

There are no studies directly comparing gummies with tablets. Gummies are convenient and need no water, but the dose per serving is what matters — always check how many gummies make up a serving.
