Staxanthin belongs to the class of carotenoids and is found in algae, crabs, fish and the feathers of some bird species. Algae are the basis of all life; astaxanthin is absorbed and utilized by animals through the consumption of these algae. While many preparations obtain their active ingredient from secondary animal sources, we have made a conscious decision to use the herbal original substance. The result is not only vegan, but also better tolerated. (e.g. for allergies to crustaceans) Naturvit® astaxanthin 4mg is lactose-free, gluten-free, sugar-free and vegan. Ingredients: filler: organic rice flour, coating agent: hydroxypropyl methylcellulose (capsule shell), astaxanthin (Astafit®) Recommended dosage: Take 1 capsule daily with a meal.
