Product insights

  • Vitamin D Synergy™ combines vitamin D3 and vitamin K (K1 and K2[MK-4]) to support bone and arterial health. Vitamin D3 enhances calcium absorption in the gut, while vitamin K helps direct calcium to bones and teeth, preventing arterial calcification.
  • This formula includes geranylgeraniol (GG), a naturally occurring compound that supports the utilization of vitamin K. GG plays a role in protein modification necessary for vitamin K-dependent processes.
  • Each capsule provides 2,000 IU (50 mcg) of vitamin D3, allowing for flexible dosing based on individual needs, sun exposure, and vitamin D status. Vitamin D3 is the preferred form of vitamin D for optimal absorption and utilization.

The research

3 cited studies
1.
Vitamin D and Bone Health

Research demonstrates vitamin D's crucial role in calcium absorption and bone mineralization, highlighting its importance in maintaining skeletal health throughout life.

2.
Vitamin K and Cardiovascular Health

Studies suggest vitamin K, particularly K2, helps regulate calcium deposition, supporting arterial health and reducing the risk of calcification.

3.
Geranylgeraniol (GG) and Vitamin K Utilization

Research indicates GG supports the carboxylation of vitamin K-dependent proteins, which are essential for bone and cardiovascular health.
