Key Ingredients
Therapeutic dose of D3 that restores deficient levels, regulates immune function, supports calcium metabolism and bone density, modulates mood via serotonin pathways, and activates Vitamin K2-dependent proteins.
MK-7 has a 72-hour half-life — far superior to MK-4 — ensuring continuous activation of osteocalcin (bone formation) and matrix GLA protein (arterial calcification prevention). Directs calcium to bone and prevents soft-tissue calcification caused by high-dose D3.
D3 and K2 are fat-soluble vitamins requiring dietary fat for absorption. Olive oil base ensures optimal bioavailability without needing to be taken with a meal.
