Key Features
-
Delivers 5,000 IU (125 mcg) of vitamin D3 per capsule
-
Includes vitamin K1, MK-4, and MK-7 forms of vitamin K
-

-
Convenient once-daily formula for comprehensive support
Why This Combination Works
Vitamin D3 (Cholecalciferol)
Often referred to as the “sunshine vitamin,” D3 helps support calcium absorption and contributes to healthy immune, bone, and cognitive function. Many people may not obtain adequate levels of vitamin D through sunlight or food alone, making supplementation a practical choice for daily wellness.
Vitamin K1 and K2 (MK-4 + MK-7)
Vitamin K plays a key role in supporting bone mineralization and helping the body properly manage calcium. It assists in directing calcium to bones while helping maintain balance in soft tissues like arteries. MK-7 stays active longer in the body, while MK-4 is quickly absorbed—both forms are included for broader coverage.
Sea-Iodine™ (Natural Iodine Source)
Iodine is a trace mineral essential for the production of thyroid hormones, which help regulate metabolism and energy balance. This formula uses a concentrated source of iodine derived from sea vegetables to help support adequate intake—especially for those following low-salt or plant-based diets.
