QUICK ANSWER

Hyaluronic Acid: Skin hydration · joint lubrication. Oral hyaluronic acid significantly improves skin hydration and elasticity. Also supports joint synovial fluid. Standard dose 120 mg, taken in the morning, about $22/month. Evidence rating: strong evidence.

What is Hyaluronic Acid?

Hyaluronic acid is a glycosaminoglycan that holds up to 1,000 times its weight in water, giving skin its plumpness and joints their cushion. Body production drops sharply after age 40. While topical hyaluronic acid hydrates the skin surface, oral supplementation has been shown in placebo-controlled trials to significantly increase deep-skin hydration, reduce wrinkle depth, and ease joint stiffness. Low-molecular-weight forms (typically 50-200 kDa) cross the gut barrier more effectively. Standard dose is 120-240 mg per day, with food.

WHY IT MATTERS

Oral hyaluronic acid significantly improves skin hydration and elasticity. Also supports joint synovial fluid.
