Vitamin D Synergy™

††USA Functional Medicine MDs, DOs, NDs, DCs and Nutrition Professionals surveyed in 2025 for Designs for Health.

Vitamin D Synergy™ provides clinically useful amounts of vitamin D3 and vitamin K (both K1 and K2 [as MK-4]), along with geranylgeraniol (GG), a substance produced naturally in the body, to promote optimal bone and arterial health and to maintain the immune system in proper balance.* This formula may be ideal for those looking to maintain optimal vitamin D status in the body.* It can be replaced with Vitamin D Supreme when higher targeted levels of vitamins D and K are desired. Vitamins D and K work synergistically, thus, increasing vitamin D increases the need for vitamin K.*
