Glucosamine is an amino-sugar naturally present in joint cartilage, playing a key role in synthesising glycosaminoglycans and proteoglycans — cartilage’s structural building blocks. The glucosamine sulfate here is obtained by natural organic fermentation, a pure, highly bioavailable form with no shellfish source. Phytodroitin is a 100% plant-based formulation from sea lettuce, bladderwrack and sodium hyaluronate — marine algae naturally rich in sulfated polysaccharides chemically close to animal chondroitin sulfate.

Glucosamine and chondroitin is one of the best-documented combinations in joint health. Glucosamine supports the synthesis of new cartilage components, while Phytodroitin helps maintain existing cartilage hydration by attracting and retaining water molecules — a dual build-and-preserve action. Choosing a plant-based chondroitin source removes any shellfish allergy risk and makes the product suitable for vegetarians and vegans.

Take 2 to 3 capsules a day with a meal and a large glass of water, ideally split through the day. First effects on joint comfort are usually felt after several weeks; a minimum 3-month course is recommended, as cartilage renews slowly. Can be renewed several times a year, particularly at seasonal changes or during intense physical activity.

Not recommended without medical advice for pregnant or breastfeeding women, or those on anticoagulant treatment, as chondroitin may interact with some medications. Diabetics should monitor blood sugar during glucosamine supplementation. Those allergic to algae or seafood should check tolerance before starting. Keep out of reach of young children.

What’s the difference between glucosamine and chondroitin?

Glucosamine is an amino-sugar involved in building proteoglycans, cartilage’s structural components; chondroitin (here plant-based Phytodroitin) is a glycosaminoglycan that supports hydration and elasticity by attracting water molecules.

How long before I feel the effects?

Cartilage renews slowly; most users report improved joint comfort after four to eight weeks of regular use, with a minimum 3-month course recommended.

Is this suitable for vegans?

Yes, entirely vegan — fermentation-derived glucosamine sulfate, algae-based Phytodroitin instead of animal chondroitin, and pullulan capsule shells, with no animal ingredients at all.
