D-Evail™ Supreme provides a clinically relevant serving of 5,000 IU (125 mcg) of vitamin D in a highly absorbable form alongside vitamins 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 health 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.*
