Wild Nutrition's Food-Grown® Selenium Plus is expertly formulated. This important mineral works to optimise glutathione peroxidase levels to support the immune system. Selenium is also required for thyroid hormone conversion and for men, it is essential for normal spermatogenesis. Vitamin E has been included in our formulation to prevent the harmful production of free radicals, highly destructive molecules that may alter DNA and cause extensive damage to the body including premature ageing and how well our body responds to insulin. Wild Nutrition's Food-Grown® Vitamin E provides the naturally occurring d-alpha tocopherol form, as well as a natural mix of all the tocopherols and tocotrienols found in food. Studies have shown it to be over nine times better retained in the body than synthetic forms.
