Life Extension Vitamins D and K with Sea-Iodine™
Life Extension® Vitamins D and K with Sea-Iodine™ combines three essential nutrients—vitamin D3, vitamin K1 and K2, and iodine—into one convenient daily capsule. Together, these nutrients support multiple areas of health including bone strength, immune system function, thyroid hormone production, and vascular health.
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
-
Provides 1,000 mcg of iodine sourced from marine vegetation
-
Supports bone, brain, thyroid, and arterial wellness
-
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.

-
Non-GMO and independently tested for purity and quality
Suggested Use
