This pure vegan N-Acetyl Glucosamine comes from a natural biofermentation process, environmentally responsible and free of animal material. This method uses specific microorganisms capable of converting plant substrates into NAG, guaranteeing exceptional purity (above 98%) and the total absence of animal or chemical contaminants. Unlike classic glucosamine extracted from shellfish, this version suits allergy sufferers and vegans alike, with rigorous testing carried out on every batch.

As a direct precursor of hyaluronic acid, NAG plays a fundamental role in the skin’s natural hydration. Including it in a beauty routine can help improve skin elasticity and soften visible signs of ageing, such as wrinkles and dryness. Many users report a noticeable improvement in skin suppleness, with fewer cracks on exposed areas — effects rooted in NAG’s intrinsic ability to stimulate the synthesis of cellular components essential to tissue cohesion.

Although NAG is less well known than glucosamine sulfate for joint protection, it offers real complementarity. Combining the two molecules can reinforce an overall strategy to preserve cartilage quality, support mobility and reduce discomfort linked to age or sustained physical activity. NAG’s light structure and high water solubility allow it to cross the digestive barrier easily, providing optimal availability at the joints, with any excess naturally eliminated to avoid unwanted accumulation. The chemical structure of NAG also gives it up to three times greater bioavailability than some classic sulfated glucosamine forms.

Take 2 capsules a day (1000mg of NAG) with a large glass of water, preferably with a meal. Digestive tolerance is excellent even with extended use, and some users also report a beneficial effect on the digestive system. A renewable course of several weeks is recommended for optimal results.

Do not exceed the recommended daily dose. Food supplement. Not a substitute for a varied, balanced diet and a healthy lifestyle. Keep out of reach of children.

What is the difference between N-Acetyl Glucosamine and glucosamine sulfate?

NAG acts mainly on the skin, as it directly participates in hyaluronic acid synthesis, essential to skin hydration. Glucosamine sulfate targets cartilage and joint support more specifically. NAG has very high bioavailability, while glucosamine sulfate’s is moderate. The two molecules are complementary and can be combined.
