Liposomal D Supreme provides vitamins D and K formulated with liposomal technology. Vitamin D is needed for a healthy immune system, and vitamins D and K act synergistically to support healthy bones and proper calcium balance in the body.* Liposomes are spheres made of phospholipids — the primary building blocks of cell membranes. Owing to this structure, liposomes bond easily with cell membranes to facilitate intracellular delivery of their nutrient cargo. Thanks to this enhanced delivery system, nutrients delivered in liposomal form offer superior absorption and bioavailability. Each 0.5 mL serving (1 pump) of this citrus-flavored formula provides 2500 IU of vitamin D3 and 325 mcg of vitamin K (as both K1 and K2). Recommended Use: Take 0.5 mL (approximately 1 pump) and hold in mouth for 30 seconds before swallowing 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.
