The Synergistic Interplay between Vitamins D and K

Fat-soluble vitamins D and K have a synergistic interplay in several health-supportive functions. Animal and human studies focusing on genetic, molecular, and cellular aspects suggest that optimal vitamin D and vitamin K concentrations support healthy bone and heart function. Both vitamins play a critical role in calcium metabolism. Calcium absorption, assimilation, and utilization are sophisticated processes requiring adequate amounts of vitamin D3 and vitamin K2-7. Research has shown that administering vitamins D3 and K2-7 supports improved calcium absorption in the gastrointestinal system and directs calcium away from tissues into bone. Vitamin K2 supports the removal of calcium from tissues and transports it to the bone where it belongs, maintaining optimal bone health. Vitamin D3 supports and maintains intestinal calcium and phosphorous absorption for optimal bone mineral matrix formation, making vitamin D one of the most important vitamins for supporting strong, healthy bones. Vitamin D3 also plays a vital immune function-supportive role.

Sourcing matters with supplemental K2, as synthetic K2 is pervasive on the market. We use only natural K2 in our supplements, which is the only way to produce 100% trans isomer (all K2-7). Synthetic forms of K2 can contain up to 40% cis isomer, meaning that percentage is of unknown constitution. Our form of K2 is produced from natural fermentation, making it the most biologically active and bioavailable form available.

MegaQuinD₃™ is a high-potency K2/ D3 supplement, combining two essential nutrients that support and maintain bone and cardiovascular health. Current research suggests that supplementing with vitamins D and K together may be significantly more supportive for bone and heart health than taking either vitamin alone.
