Bronson Vitamin K2 D3 (MK7) Supplement Non-GMO Formula Vitamin D3 5000 IU (125 mcg) & 90 mcg K2 MK-7, Easy to Swallow D & K Complex, 120 Tablets

Discover the science of vitamin D3 and K2 synergy with Bronson's expertly crafted supplement, designed to support your everyday wellness in a convenient tablet form.

Understanding the Synergy: How D3 and K2 Work Together

The synergy between D3 and K2 is rooted in cellular biology. Vitamin D3 (cholecalciferol) supports the production of calcium-binding proteins in the gut, which enhances calcium absorption. Meanwhile, vitamin K2 (menaquinone) activates two critical proteins: osteocalcin, which helps bind calcium to the bone matrix, and matrix GLA protein (MGP), which helps prevent calcium from depositing in blood vessels. The MK-7 form of K2 used in this supplement is especially effective because it remains active in the bloodstream for up to 24 hours, providing sustained support for these processes. This sustained activity means a single daily dose of MK-7 can maintain consistent levels throughout the day.*

Why Take Vitamin D3 and K2 Together?

Vitamin D3 and K2 form a powerful combination for overall health. Vitamin D3 helps your body absorb calcium from the foods you eat, while vitamin K2 directs that calcium to your bones and teeth—and away from soft tissues like arteries. This teamwork is essential for maintaining strong bones, healthy teeth, and a flexible cardiovascular system. Without enough K2, the calcium absorbed thanks to D3 may not reach the right places. That's why many health experts recommend taking them together for optimal results.*
