Unusually for the joint care aisle, this glucosamine is entirely vegan. Most glucosamine is extracted from shellfish, but Viridian uses a plant-derived form, glucosamine sulphate 2KCl, paired with MSM, a naturally occurring source of sulphur, one of the raw materials found in the body's connective tissue. This 90 capsule bottle suits committed daily users.

Each vegetarian capsule provides 700mg of vegan glucosamine sulphate 2KCl with 125mg of MSM (methyl sulphonyl methane) in a base of alfalfa, spirulina and bilberry. There are no artificial fillers, GMO ingredients or palm oil, and the formula suits anyone avoiding shellfish. Take one to two capsules daily with food, making this pot up to three months' supply. Not to be used during pregnancy or breastfeeding unless recommended by a healthcare practitioner.
