Vitamin D Supreme provides clinically useful amounts of vitamin D3 and vitamin K (both K1 and K2 [as MK-4]), along with geranylgeraniol (GG), a substance produced naturally in the body, to promote optimal bone and arterial health and to maintain the immune system in proper balance.* The amount of vitamins D and K in this formula may be beneficial for those who do not receive adequate sun exposure and/or dietary sources of these vitamins. Vitamins D and K work synergistically, thus, increasing vitamin D increases the need for vitamin K.* Recommended Use: Take one capsule per day with a meal, or as directed by your health-care practitioner. Warning: Consult your health-care practitioner before using this product if you are taking Coumadin, warfarin or other anticoagulant medications. * These statements have not been evaluated by the Food and Drug Administration.
