One of the essential amino acids the body cannot make for itself, presented as a clean single-ingredient supplement from Viridian, the ethical nutrition brand founded in Staffordshire in 1999. This 90 capsule bottle suits anyone wanting a longer-lasting supply, and vegans and vegetarians in particular often choose to top up their lysine intake, as plant-based diets can provide less of it.

Each vegan capsule delivers 500mg of L-lysine in its free form, meaning it requires no digestion before the body can absorb it. In typical Viridian style there are no artificial fillers, binders or additives, just the active ingredient in a plant cellulose capsule. Take one to three capsules daily with food, or as advised by your health practitioner. Viridian donates a share of its profits to charitable causes, which is one of the reasons we like stocking the range.
