D-Evail™ 10K is our highest potency vitamin D product, providing a clinically relevant serving of 10,000 IU (250 mcg) of vitamin D in a highly absorbable form alongside vitamins K1 (as phytonadione) 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 the Designs for Health® Evail™ technology that combines quillaja extract with medium-chain triglycerides (MCT) for improved nutrient bioavailability.*
