Hyaluronic acid products compared
| Product | Form | Daily dose | Hyaluronic acid | Pack lasts |
|---|---|---|---|---|
| OstroVit Hyaluronic Acid 70 mg, 90 tablets | tablet, sodium hyaluronate | 1 to 2 tablets with a meal | 70 to 140 mg | 45 to 90 days |
| NOW Foods Liquid Hyaluronic Acid Plus, 473 ml | liquid, sodium hyaluronate | 15 to 30 ml (1 to 2 tablespoons) | 200 mg per 30 ml | about 16 to 31 days |
The tablet gives a fixed number of milligrams per piece. The liquid is dosed by volume, so the amount you take depends on how many spoonfuls you measure, up to 200 mg at the 30 ml serving.
What is in the liquid
The NOW Foods liquid is not hyaluronic acid alone. Per 30 ml the label lists 200 mg of hyaluronic acid, 200 mg of free proline, 200 mg of L-lysine, 600 µg of vitamin A and 20 µg of vitamin D, in a base with 4 g of xylitol and 40 kcal. The label warns that xylitol is harmful to animals, so keep the bottle away from pets. Shake before use and take it straight or mixed with water or juice.
Reading the label
- Form: sodium hyaluronate, the sodium salt of hyaluronic acid.
- Amount per tablet or per 30 ml, not per pack.
- Extra ingredients: tablets add filler and anti-caking agents, the liquid adds amino acids, vitamins and sweetener.
- Allergens: OstroVit lists possible traces of milk, soy, nuts, gluten and others.
Health claims
The EU register of authorised health claims has no statement for hyaluronic acid. Under Regulation (EC) No 1924/2006 we therefore do not describe effects on skin, joints, eyes or anything else, and any page that does is going beyond what the EU allows. The vitamins in the liquid are covered by their own permitted statements on that product page. Hyaluronic acid itself has none.
Before you buy
The OstroVit label says the product is not for children, pregnant or breastfeeding women. NOW Foods says it is for adults only and advises pregnant or breastfeeding women, people on medicines and people with a medical condition to consult a doctor. Do not exceed the daily dose. Related ranges include collagen, marine collagen and hair vitamins, each with its own label.
Questions
Tablets or liquid?
The tablet is a fixed dose with no sweetener. The liquid is measured in spoonfuls and adds proline, lysine and vitamins A and D. Choose by form and by what you want on the label.
How do I take them?
OstroVit says 1 to 2 tablets a day, best with a meal. NOW Foods says 15 ml once or twice a day, shaken first.
Is hyaluronic acid the same as collagen?
No. They are different substances with separate labels and separate categories in the shop.
How long does a pack last?
OstroVit lasts 45 to 90 days depending on 2 or 1 tablets a day. The 473 ml bottle lasts about 16 days at 30 ml a day and about 31 days at 15 ml.
