About this item
- VITAMIN D “SUNSHINE VITAMIN” - supports healthy bone density and structure; Vitamin D is required for optimal calcium absorption
- BENEFITS OF VITAMIN D3 - enhances and regulates immune function, supports optimal cardiovascular function and enhances cellular function
- GET YOUR NEEDED DAILY DOSE - Approximately 75% of Americans are deficient in vitamin D. Some researchers suggest that a minimum daily intake of 1,000 IU is necessary to maintain barely adequate blood levels of vitamin D. Others agree that much higher doses are needed to ensure levels are optimal enough to promote health.

Doctor’s Best Vitamin D3 provides D3 (as cholecalciferol) needed for the body to regulate phosphorus and calcium levels for healthy bones, teeth and heart. Vitamin D3 is produced in the skin by absorbing the sun’s UV rays and is obtained from food in limited amounts. Sun protection and climate factors may influence low Vitamin D3 levels.
Vitamin D3 is beneficial for immune, cardiovascular, bone density and structure, and cellular function. It plays a role in most organs and systems of the body and influences the chemical messengers of the immune system.*
Vitamin d from dietary intake or sun exposure requires two activation steps in the body. The first activation occurs in the liver, while the second activation occurs in the kidneys, allowing for regulation of calcium metabolism. However, vitamin d receptors are present throughout the body, in tissue such as the skin, cartilage, heart, prostate, bones and intestines. Thus, the second activation step also takes place in local tissues. Recent discoveries have highlighted the important modulatory effects of vitamin d on various cells of the immune system.vitamin d enhances and regulates immune function. It is known that various cells of the immune system, such as t lymphocytes and antigen presenting cells, express the vitamin d receptor on their surface when activated. Recently, it has been found that treatment of these immune cells with vitamin d influences their expression of cytokines, which are chemical messengers of the immune system. The immune modulating effects of vitamin d extend to monocytes and dendritic cells of the immune system as well. Dendritic cells are important antigen-processing cells of the immune system that function to initiate the immune response. Vitamin d may prevent overactivity of the immune response and keep the immune system in a normal healthy state of vigilance.vitamin d supports optimal cardiovascular function. Research has uncovered the role vitamin d plays in supporting cardiac function. Heart myocytes (cells) express the vitamin d receptor, as do smooth muscle cells of blood vessels. The benefits of vitamin d on the heart are potentially far-reaching. Studies on mice heart cells have shown that vitamin d administration impacts their growth and proliferation. In these cells, vitamin d inhibited the release of a protein that could be detrimental to the function of these cells, displaying cardioprotective properties. It has also been shown that vitamin d has a modulatory effect on heart rhythm.
