Description

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.

Features:

• Vitamin D "Sunshine vitamin" – supports healthy bone density and structure; Vitamin D is required for optimal calcium absorption
• Product Note: Exposure to heat or sunlight may lead to melting/damage of product. Hence customers are expected to be available during the product delivery
• 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.
