Turmeric, the Indian spice that gives curry its yellow colour, has become a very popular nutritional ingredient. The main active ingredient, curcumin, also works as an antioxidant, neutralizing “free radical” cells in your body that can be the cause of serious ailments. Spirulina is another rich source of healthy nutrients. It’s a form of tiny algae that’s loaded with amino acids, B-complex vitamins, calcium, and other minerals. Spirulina gives these CBD edibles their deep-green colour.
