Swanson Vitamin D3 is an essential bone supporting vitamin that works to absorb calcium efficiently in the body. The body manufactures some vitamin D on its own when it is exposed to sunlight, but for people living in the northern latitudes where wintertime sun exposure is limited, the body's natural vitamin D may often be insufficient. Our High Potency Vitamin D3 capsules tackle this problem by supplying an impressive 1,000 IU of vitamin D3, the most biologically active fraction of vitamin D.

Per GMP guidelines set forth by the FDA, most products are formulated for 24 months from the date of manufacture. Liquids and probiotics are formulated for 12 months. Most biologically active form of vitamin D. Promotes calcium absorption in the body. Supports bone health plus immune and cardiovascular wellness.
