Vitamin D (Cholecalciferol, Ergocalciferol) Hot

Vitamin D (Cholecalciferol, Ergocalciferol)

The name 'vitamin' is actually a misnomer when it comes to vitamin D. Rather than a vitamin this nutrient is actual the precursor to the body's most potent steroid hormone, often referred to as 'activated vitamin D'.

Vitamin D can either be obtained from the diet in the form of cholecalciferol (vitamin D3), from animal sources, or ergocalciferol (vitamin D2), from plant foods, or it can be made in the skin when it is exposed to the ultraviolet (UV) radiation from the sun's rays.

Vitamin D from all sources is metabolised by the liver, kidneys and other tissues to its activated form.

The most well known function of vitamin D is its role in maintaining blood levels of calcium through mechanisms including controlling the rate of absorption of this mineral from foods. As such vitamin D, along with calcium, is known to be important in the maintenance of bone mass and the prevention of diseases such as osteoporosis.

More recent research however has revealed that vitamin D has a whole host of other important functions within the body and there are no doubt many more yet to be discovered. Some of these functions include:

Immune System Regulation - Vitamin D is known to stimulate the innate immune system; the part of the immune system which is non-specific and responds first to infection. This part of the immune system includes neutrophils, by far the largest sub-type of white blood cell, and the first on the scene when bacteria and other pathogens invade the body. Vitamin D has also been found to play a role in suppressing other portions of the immune system that may lead to the development of autoimmune disorders such as rheumatoid arthritis and systemic lupus erythamatosus (SLE).

Cancer Prevention - Connected to its role in immune system regulation is the fact that vitamin D appears to help prevent certain forms of cancer. Since activated vitamin D is a potent steroid hormone it is involved in turning genes on and off. Some of these genes are involved in processes that control cell growth and replication. If the wrong genes are overly expressed cancer may develop. It appears that vitamin D regulates gene expression so that cellular growth and replication occurs in a healthy way and cancerous cells do not develop. Forms of cancer that vitamin D has been shown to be protective against include breast, ovarian, prostate, and colon cancers.

Mood Regulation - Vitamin D activates the enzyme that leads to the production of the catecholamine neurotransmitters (dopamine, noradrenaline etc) that improve mood, motivation, focus and attention. Vitamin D also increases levels of serotonin, the "happy" neurotransmitter associated with feelings of contentment. Studies have shown that vitamin D levels are lower in depressed patients than in healthy individuals, that it improves mood even in healthy individuals, and in high doses is a more effective treatment for seasonal affective disorder (SAD) than bright light therapy.

Autism - Although studies are needed to confirm any link between vitamin D levels of either mothers during pregnancy or children in their early years and the development of autism, the Vitamin D Council postulates that such a link can account for many of the epidemiological trends seen in the disorder.

Turned winter into summer for a SAD sufferer

As someone who has suffered from seasonal affective disorder (SAD) for many years I have tried bright light therapy with various light boxes, a lot of anti-depressant medications, and even more nutrients and herbs in an effort to maintain my mood in winter. Bright light therapy was mildly effective but the best treatment I had found was simply waking with the sun and getting outside in the sun's rays as often as possible.

That was until I discovered high dose vitamin D. This year I tried taking vitamin D3 (cholecalciferol) concentrate in doses of 25,000+ iu per week. My response to this treatment was rapid and substantial. It may be hard for other SAD sufferers who are deep in despair to believe, but after only a few hours of the first dose I felt in my mind like it was summer. My mood improved hugely, everything seemed brighter, and I found myself enjoying things again.

The only downside for me was that I found I was overly stimulated at night which made it difficult to sleep. However, this happens with any stimulating substance I take due to adrenal fatigue so may not be a problem for others. If it is just try adjusting the dose downwards.

I went through my doctor to get the vitamin D3 concentrate as it is not widely available. It is a good idea to work with a healthcare professional when using such high doses anyway despite vitamin D's apparent lack of toxicity.

helped my fibromyalgia pain

i have suffered from fibromyalgia and severe pain for 4 years and have had little help from prescription and non-prescription painkillers. they often help for a while but the effects fade and i need ever increasing dosages....which i don't feel comfortable with. after reading that vitamin D deficiency is common and can result in widespread pain i thought trying supplements was worth a shot. i was really surprised how well they worked. after a week of taking 3000 iu per day the severity of my pain was noticeably less and i was more mobile.

the improvements have continued and i have now been taking the vitamin D supplements for 2 months. i am not taking any painkillers regularly anymore, just on the odd occassion where the pain flares up. i have also noticed that my low mood has improved somewhat and i feel much brighter and more motivated. the vitamin D supplements are very cheap and i haven't noticed a single sideeffect.

if you suffer from fibromyalgia or general pain please give vitamin D a try.

fibromyalgia, depression
