Hyaluronic acid is naturally present in the body, concentrated in skin, eyes and joints, and prized for its exceptional water-retention capacity — a single molecule can hold up to a thousand times its weight in water. It plays a fundamental role in skin hydration and tissue elasticity. Endogenous production gradually declines with age, typically starting around 25 and accelerating over the decades.

Oral supplementation complements topical skincare. Unlike creams and serums that act on the surface, an oral hyaluronic acid supplement is absorbed digestively and distributed across all tissues. The “in and out” approach — combining topical care with oral supplementation — is increasingly favoured by nutricosmetics professionals to maximise deep hydration and joint comfort.

The GreenIuronic process yields high-molecular-weight hyaluronic acid from the controlled fermentation of organically grown Tremella fuciformis mushroom, used for centuries in Asian tradition for skin and beauty care. Organic certification guarantees no pesticides or chemical solvents in cultivation and extraction. GreenIuronic Organic is a registered trademark of Vivatis Pharma GmbH.

Take 1 to 2 capsules a day, preferably in the morning with a large glass of water, with or without food. A programme of 1–3 months is generally recommended, renewable as needed; first effects are usually noticed after 3–8 weeks of regular use. Pairs well with collagen, vitamin C, omega-3 or zinc.

Do not exceed the recommended daily dose. Seek advice from a healthcare professional if pregnant, breastfeeding or on medical treatment. Store away from heat, moisture and direct light, out of reach of children.

Is oral hyaluronic acid as effective as injections?

These are different approaches with different goals — injections are aesthetic-medicine procedures for localised, immediate volume/wrinkle correction; oral supplementation supports skin hydration and elasticity globally and gradually. They can be complementary.

Can it be combined with other supplements?

Yes — it pairs well with collagen, vitamin C (which contributes to normal collagen formation for normal skin function), omega-3 and zinc.

What’s the difference between plant and bacterial hyaluronic acid?

Plant-based hyaluronic acid, like this Tremella fuciformis GreenIuronic extract, comes from fermenting an organically grown plant organism; bacterial hyaluronic acid is produced by fermenting Streptococcus strains. Both are effective, but the plant route allows organic certification.
