Vitamin D3, Extra Strength 2000 IU (60 Capsules)
Vitamin D3 is an essential nutrient which serves a vital role in strengthening bones, balancing mood, and maintaining a healthy immune system!
What is Vitamin D3?Vitamin D is a fat-soluble vitamin found in food, which is also created naturally within your body after exposure to ultraviolet rays from the sun. Throughout human history, exposure to sunlight has been the predominant source for Vitamin D within the body – this has made supplementing with Vitamin D all the more essential in modern times, as our indoor work environments and living habits have greatly decreased our regular exposure to the sun.
Health Benefits Of Extra Strength Vitamin DTraditionally, it was thought that the primary benefit of taking Vitamin D was to maintain normal blood levels of calcium and phosphorus. While it’s true that this is certainly one of the essential functions of Vitamin D, in recent years an incredible wealth of research has emerged on Vitamin D, showing it to be of vital importance to the health of not only bone tissue, but also the brain, nervous system, and immune system within the body. Many studies have even found a correlation between Vitamin D levels and the way people feel emotionally - truly, this is an amazing nutrient!
Our Vitamin D3 Supplement is a Great ValueIn the world of supplements, Vitamin D3 is typically sourced from cod liver oil, animal hides, or lanolin.

The fat-soluble vitamin D’s most important role is maintaining blood levels of calcium, which it accomplishes by increasing absorption of calcium from food and reducing urinary calcium loss. Both effects keep calcium in the body and therefore spare the calcium that is stored in bones. When necessary, vitamin D transfers calcium from the bone into the bloodstream, which does not benefit bones. Although the overall effect of vitamin D on the bones is complicated, some vitamin D is necessary for healthy bones and teeth.
When "D” is used without a subscript it refers to either D2 or D3, the two primary forms used as supplements.
- Reliable and relatively consistent scientific data showing a substantial health benefit.
- Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
- For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
