Now Foods Vitamin D-3 400 IU is a dietary supplement containing vitamin D3 in the form of cholecalciferol obtained from lanolin. Vitamin D3 was suspended in high-quality extra virgin olive oil, which increases its stability and assimilability. One capsule contains 400 IU (10 mcg) of vitamin D3.
Vitamin D3 is a compound soluble in fats with steroid structure. Partial, but insufficient need for this essential vitamin is covered by skin synthesis. Vitamin D3 present in skin under the influence of UV-B radiation is converted to vitamin D3 and then in the liver and kidneys to the active calcidiol and calcitriol.
Calcitriol - an active form of vitamin D3 works by means of nuclear receptors VDR (vitamin D receptor), located in cells of almost all organs - bones, intestinal epithelium, heart, brain or pancreas. Activation of these receptors influences the expression of ca. 200 genes. Moreover, calcitriol, by acting through membrane receptors, influences the activation of kinases, proteases and the synthesis of prostaglandins.
Vitamin D3 regulates calcium-phosphorus balance, essential for proper mineralization of bones and calcium absorption. It has protective influence on cells of osseous and cartilaginous tissue. Vitamin D3 deficiency in children results in rickets and improper bone mineralization and in adults it leads to bone pain and osteoporosis.
Vitamin D3 regulates the activity of the immune system of the organism. Activation of neutrophils of VDR receptors located in lymphocytes T and B influences decreasing inflammations. Vitamin D3 stimulates maturation of monocytes to macrophages, responsible for phagocytosis of pathogens and chemotaxis. Deficiency of this vitamin, by causing the decrease of the activity of acid phosphatase disturbs differentiation of monocytes, which consequently leads to weakening the organism’s immunity. Moreover, vitamin D3 deficiency is related to numerous autoimmune and infectious diseases.
An important direction of therapies of autoimmune diseases is reduction of inflammations in the organism. Vitamin D3 may decrease inflammation caused by the intensified synthesis of the so-called tumor necrosis factor in rheumatoid arthritis. It may be also helpful in the therapy of psoriasis.
Vitamin D3 causes the increase of glutathione level in the organism. Glutathione (GSH) is a tripeptide appearing in the highest amounts in the liver - a filter which protects the organism from the activity of toxins. Glutathione is a strong antioxidant, which protects the organism from oxidative stress and biochemical reactions with its participation are mainly detoxifying, enabling the elimination of toxic substances from the organism. Decreasing oxidative stress is important from the neuro- and cardioprotective point of view and from the point of view of degenerative and cardiovascular system diseases.
To sum up, Now Foods Vitamin D-3 400 IU is a preparation recommended for longer supplementation, especially in deficiencies of vitamin D3, in order to ensure proper mineralization of bones and teeth in the periods of fatigue and in order to improve well-being and general state of health.
