VITAMIN D IN-DEPTH

Vitamin D is required for the metabolism of the minerals calcium and phosphorus, thus plays an important role in maintaining proper bone structure. Vitamin D is a potent immune system modulator, plays a role in the regulation of insulin secretion, blood-pressure, muscle-contraction, nerve transmission, and cell differentiation. Activated vitamin D (calcitriol) is a pluripotent pleiotropic secosteroid hormone. As a steroid hormone, which regulates more than 1000 vitamin D-responsive human genes. Sun exposure is an easy, and reliable way to get vitamin D, because Vitamin D3 (cholecalciferol) can be synthesized by humans in the skin upon exposure to UVB radiation from sunlight.

 

MAY BE HELPFUL IN PREVENTING OSTEOPOROSIS, AND PRESERVING BONE HEALTH

Vitamin D supplements may be helpful in preventing osteoporosis, preserving bone health, reducing bone loss and fracture rates in the elderly. A prospective study found that those who consumed at least 600 IU/day of vitamin D had a 37% lower risk of osteoporotic hip fracture than women who consumed less than 140 IU/day of vitamin D.

 

DECREASE THE RISK OF SEVERAL AUTOIMMUNE DISEASES

Maintaining sufficient vitamin D may help decrease the risk of several autoimmune diseases, such as insulin-dependent diabetes mellitus, multiple sclerosis, and rheumatoid arthritis. Epidemiological and prospective cohort studies have found that adequate vitamin D intake could possibly decrease the prevalence of IDDM, MS, and RA.

 

IMPROVES THE FUNCTION OF IMMUNE SYSTEM

Vitamin D sullpementation may be an effective way to boost immunity and arm the immune system against disorders like the common cold and flu. Scientists have discovered that Vitamin D is crucial to activating immune defenses and that without sufficient intake of the vitamin, the killer cells of the immune system will not be able to react to and fight off serious infections in the body. A particular study found that those with deficient vitamin D levels were 55% more likely to have contracted a recent cold or upper respiratory infection than those with an adequate level.

 

IMPROVES HIGH BLOOD PRESSURE

Vitamin D supplementation appears to decrease blood pressure. Adequate vitamin D levels may be important for the appropriate regulation of the renin-angiotensin system which plays an important role in the regulation of blood pressure.

 

HELPS FAT-LOSS

Supplementing with vitamin D can increase the rate of weight loss during dieting. Vitamin D acts like a hormone by delivering message to cells, preventing fat storage. In the absence of sufficient vitamin D the body increases the number and size of newly formed fat cells that promote and accelerate abdominal obesity.

 

IMPROVES GLUCOSE METABOLISM

Vitamin D supplementation may improve glucose metabolism. Insufficient vitamin D levels may have an adverse effect on insulin secretion and glucose tolerance in type 2 diabetes.

 

IMPROVES ATHLETIC PERFORMANCE

Vitamin D may improve athletic performance. Studies undertaken decades ago in Russia and Germany, hint that the Eastern Bloc nations may have depended in part on sunlamps and Vitamin D to produce their preternaturally well-muscled and world-beating athletes. One study dating back to 1938 showed that 100-meter dash times were improved from 13.63 to 12.62 seconds, using vitamin D-producing ultraviolet lamps. A number of recent studies also have shown that, among athletes who train outside year-round, maximal oxygen intake tends to be highest in late summer.
