D-Evail� Supreme provides a clinically relevant serving of 5,000 IU (125 mcg) of vitamin D in a highly absorbable form alongside vitamin K1 and K2 (as MK-4), and geranylgeraniol (GG) to support bone, immune, and cardiovascular health.* Research suggests that combined supplementation of both vitamins D and K may be more supportive than either vitamin alone for both bone and cardiovascular health.*

This product uses Designs for Health's Evail� system technology that combines quillaja extract with medium-chain triglycerides (MCT) for improved nutrient bioavailability.
