Proven Benefits

01Improves hydration and wrinkles

02May reduce knee osteoarthritis pain

Chemical Forms

Recommended

Low-molecular-weight hyaluronic acid
Sodium hyaluronate

Avoid

Undefined molecular weight (absorption uncertain)

Expert Note

Low-molecular-weight hyaluronic acid (roughly 50–300 kDa) may be absorbed more readily than very high-molecular-weight forms. Sodium hyaluronate is the stable salt used in most clinical trials and standard supplements.

Protocol

Amount

120–240 mg

Frequency

Once daily

When

Any time of day — consistency matters more than timing.

Condition-Based Dosing

Skin aging and dryness

120–240 mg daily for 8–12 weeks— Assess skin hydration and wrinkle appearance after 12 weeks; continue only if noticeable benefit.

Mild knee osteoarthritis

200–240 mg daily for 8–12 weeks— Consider combining with glucosamine/chondroitin if no improvement after 12 weeks.

Safety & Limits

Upper Safe Limit

No established tolerable upper limit; doses up to 240 mg/day studied without adverse effects.

Cycling

Safe for continuous use

Contraindications

Pregnancy or breastfeeding — insufficient safety data for oral supplementation

Synergies

Collagen peptides

Collagen provides structural protein while hyaluronic acid retains moisture, together supporting skin matrix and joint tissue.

Vitamin C

Vitamin C is required for collagen synthesis and may enhance the skin-matrix benefits of hyaluronic acid.
