  • Designs for Health D-Evail 10K (Formerly Vitamin D Ultra 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.

Recommended Use:

Take 1 softgel per day, or as directed by your health-care practitioner.

Excellent Vitamin D

My functional doctor recommended this brand of vitamin D. I take one 10k capsule daily without fail. It keeps my levels high and steady. There are so many vitamin D supplements on the market to choose from. Do not hesitate to purchase this brand.
