NSI Vitamin D3 (as Chole calciferol) -- 4000 IU - 300 Capsules

Vital for calcium absorption and the maintenance of healthy bones and teeth. Supports cardio, breast, colon, nerve and cellular health. Fortifies the immune system. How Does NSI® Vitamin D3 work? Vitamin D is vital to maintaining healthy calcium levels in the body. Calcium, the main structural element in bones and teeth, can only be absorbed by the body when vitamin D is present. This makes vitamin D essential for building and maintaining healthy bones and teeth. Increased levels of vitamin D also enhances breast and colon health, supports normal inflammatory response, helps strengthen the immune system, contributes to muscle strength,  works to maintain proper nerve function and helps regulate cellular growth.  In addition, vitamin D supports blood pressure and triglyceride levels already within normal range, Vitamin D3 (also known as cholecalciferol) is the preferred form of vitamin D because it is the most powerful, active form. Vitamin D3 is manufactured by the body when skin is exposed to the UV rays of the sun. However, it is not always possible to get your daily dose of vitamin D3 from the sun, making supplementation beneficial. . Recent studies suggest that the current RDA/DV of vitamin D (200 IU for individuals under age 50, 400 IU for those between the ages of 50 and 70, and 600 IU for those over the age of 70) may not be adequate. In fact, optimal levels are between 2,000 and 4,000 IU per day. NSI® Vitamin D3 is better because it:. - Provides 4,000 IU of vitamin D3 per each single capsule serving. - Delivers the active and preferable form of vitamin D.  . Did You Know? All NSI supplements are packaged in HDPE (High Density Polyethylene) bottles. These bottles keep moisture vapor out, protecting the freshness and integrity of their contents, and are 400% more effective compared other brands currently using PET (Polyethylene Terephthalate) bottles. HDPE bottles do not break as glass can and are also recyclable so we urge you to please recycle them.
