Oral Hyaluronic Acid

Reviewed by the Nimbera editorial team · Last updated May 2026

Hsu 2021 Nutrients (PMID 34203487) - double-blind RCT, 40 healthy adults aged 35-64, 120 mg oral HA daily for 12 weeks significantly improved wrinkle score, stratum corneum water content, transepidermal water loss, and skin elasticity vs placebo.$15-$35 per month for a 120 mg daily dose

How to use

Take 120 mg of oral hyaluronic acid once daily with water, preferably with a meal. Choose low-molecular-weight HA (< 300 kDa) formulations when possible, as these have shown superior wrinkle outcomes in comparative trials. Allow at least 8-12 weeks for noticeable results.

How it works

Orally ingested HA is partially degraded to oligosaccharides and short-chain fragments that are absorbed via the gut and distributed to connective tissues including the dermis. These fragments stimulate fibroblast hyaluronan synthesis and may act as signaling molecules that support the extracellular matrix, improving dermal water-binding capacity and skin turgor.

Where to buy

NOW Foods Hyaluronic Acid 100 mg, Jarrow Formulas Hyaluronic Acid, Sports Research Hyaluronic Acid. Available at iHerb, Amazon, Whole Foods, and GNC.

Safety notes

Generally very well tolerated with no serious adverse effects reported in clinical trials. Not recommended for individuals with active cancer (HA can theoretically support tumor matrix) without oncologist discussion. Not a substitute for topical moisturizers or sunscreen for photoaging prevention.
