Hyaluronic Acid

Description

Hyaluronic Acid (HA) is a powerful humectant, meaning it can draw moisture from its surroundings and hold onto it, with the capacity to bind over 1,000 times its weight in water. This vital molecule is naturally produced in the body, predominantly found in the skin, joints (as a major component of synovial fluid), and eyes, where it contributes to tissue hydration, elasticity, and overall structural integrity. In the skin, HA helps maintain a youthful plumpness, firmness, and a dewy appearance by keeping cells well-hydrated. For joints, it acts as a lubricant and shock absorber, reducing friction and supporting smooth movement. Its presence is also critical in wound healing processes, contributing to tissue regeneration and reducing inflammation. HA's diverse roles make it a popular ingredient in both cosmetic and supplemental products. Supplementation with hyaluronic acid, typically in oral or topical forms, aims to support skin health, alleviate joint discomfort, and maintain hydration across various bodily tissues. It is widely used in anti-aging skincare products for its moisturizing and plumping effects, and in joint support formulas to help maintain cartilage health and joint fluidity.

Hyaluronic Acid is a key molecule for skin hydration, capable of holding up to 1000 times its weight in water. Clinical trials demonstrate that oral supplementation is effectively absorbed and increases the skin's moisture content, leading to a visible reduction in dryness and wrinkles and improved skin smoothness.

High effect
Typical dose:80–240 mg
While once thought to be poorly absorbed, studies now show that oral hyaluronic acid can reach the joints, where it helps to maintain the viscosity of synovial fluid. This can lead to reduced pain and improved mobility, particularly in the knees.

Typical dose:60–240 mg
Hyaluronic Acid is a key molecule for retaining moisture in tissues. Orally, it has been shown to be absorbed and distributed to the skin and joints. Supplementation can increase skin moisture content, improving elasticity and appearance, while also supporting the viscosity of synovial fluid in joints, enhancing cushioning and mobility.

Limited evidence
Typical dose:60–200 mg
Hyaluronic Acid is a powerful humectant that supports skin hydration. When taken orally, it may provide some benefit to scalp moisture. However, the direct clinical evidence for oral HA significantly impacting hair growth, thickness, or shedding is limited compared to other nutrients.
