  • 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.

Recommendation Use:

Take 1 capsule per day with a meal or as directed by your health-care practitioner.

Been taking these for many years

D level is great,

Great product

This was recommended to me by a pharmacist. It is a very good source of vitamin D and absorbs well because of the added K.
