You can now add MS to that list of diseases, Australian Medical Scientists have just now discovered a link between MS and Vitamin D Deficiency

Dr Mercola is a genius, but not only is he a genius he's a genius that possesses rare attributes, he actually cares about people and lo and behold he's honest!!, obviously he is making money and good on him, better he make money than those good for nothing CEOs and Company executives that could not lie straight in bed and never deliver the goods, they'll bury them all in a saxaphone case, they could hide behind a corkscrew wearing an overcoat they are that crooked.

I am starting to wonder what impact the huge expansion in drug-taking (statins, SSRIs, BP meds. etc.), especially among the elderly, may have on our bodies' abilities to process and store vitamin D. Are vitamin D levels even measured during drug trials leading to FDA approvals?

I have been considering taking a vit d3 supplement because where i live we have long winters. I don't get a whole lot of calcium... don't drink milk, i eat yogurt but not on a regular basis. I eat leafy greens and veggies that contain calcium but likely not enough on a daily basis. I have been doing some research and it appears that you need calcium for the vit d to work, and i understand it is important to have enough. I bought some vit d3 but didnt take any because of the calcium situation. I am confused. can anyone help?

My Father suffered a severe accident as a child, he was unable to walk for one year and had to stay in bed. As a young man he had constant pains in his legs and would come home from work and go to bed in pain. His forward thinking Dr. prescribed 50,000 (Fifty Thousand units) units of Vitamin D. He took one every single day for forty years and his pain was eliminated. He lived to the age of 92, he was rarely sick, he fell many times onto oak floors, concrete, fell off a chair while chaning a light bulb, he never broke a bone, he never had osteoporoses his blood tests were always better than my Mother's, my brother-in-;law's and my sister's.

My Mother on the other hand always took her calcium without fail, she had a severe case of osteoporosis and had a hump on her back and shrunk in height.

Soooo, I take lots of Viitamin D and get calcium from my food.

Just thought you'd like to know about the huge amount of Vitamin D that he took, Doctors called him "the iron man".

I talked to my doctor about this and this was his reply " have checked directly with the Director of Chemistry at Quest on this issue, and he explains that earlier in the Summer they were having some difficulties with their analysis of Vit D. They ran a report on the pateints under my care who had their Vit D levels checked during this time, and there were 2 pateints who were affected, and you were not one.

Since then they have corrected the issue. I'm not sure why Mercola continues to pound on this issue. As far as I know the issue has been cleard up."

Instead of taking a all sorts of supplements, what do you guys think of nutrition based on your DNA? I was looking at this chiropractors site at www.lifemapnutrition.com/chiropractic ;but I am not sure about it...you guys seem very knowledgeable about this stuff, so what do you think?

I have a 5 yr. old daughter with alopecia areata. I noticed that in the warm summer months she suffered no hair loss, but did in the winter. Since using cod liver oil I have noticed less loss and now with all of these new updates about the cod liver oil, I'm wondering what to do for now. How evasive is it to have her blood checked and has anyone overcome this disease? Please share!

My 116 lbs 65 years young wife has depression, inability to get quality sleep, osteoporosis, excessive Ca in urine (462 mg/24 hrs, should not be more than 150), arthritis, lupus and other autoimmune disorders. Daily, she is taking antihypertensives (6.25-7.50 mg Norvasc and 80 mg Diovan, 5 meq potassium citrate), antianxiety (0.50-0.75 mg Activan), antidepressive (200 mg Sam-e), and supplements including 50 billion cultures of flora, 500 mg Vit C, 2000 iu D3, 1 B-complex, 2 multivit, 300 mg calcium citrate, 300 mg magnesium citrate, 1 thyroid support (Thyroxal), 750 mg glucosamine, 150 mg chondroitin, 20 mg hyaluronic acid, 10 ml fish oil, 1500 mg krill oil, 30 mg coq-10, 500 mg l-arginine, 250 mg ornithine HCl, 500 mg taurine, 1 digestive enzymes tablet/meal, and 1 gluten peptide digestive enzymes/meal.

Questions: (1) What medication and parasites are known to cause Lupus and other autoimmune disorders as indicated in the Optiontrade comment? (2) Would someone please commend on the Rupi article which says that D3 supplement worsens autoimmune diseases because it hyperactivates 1,25 dihydroxy D3 to levels so high they are toxic? (3) Do calcium-magnesium, l-lysine and l-arginine intakes have any to do with the problems? (4) Would someone please commend on the Townsend Newsletter #306 saying high D3 levels lower the immunity ability to fight the disease-causing microbes as mentioned in the 4windsrider article? Thank you kindly for your help. JWL.

Dr Mercola,

is there information on the comparative strength of the different UV radiation strengths at different lattitudes?

I strongly suspect that there is a huge difference between what you get in the USA and what we receive here in Australia - and so exposure times for optimum D levels may be very different.

I am outside for moments in January before I feel a burn begin.

I note that in a recent meta-study of vitamins and selenium, they discovered a negative correlation with life expectancy, by the users, with every supplement, except vitamin C (neutral) and selenium (positive, but it's not a vitamin). It was found through a question by a representative of one of the vitamin companies concerned, however, that the study did not distinguish between synthetic supplements, and natural. When corrected, they all showed positive effects. I am informed that unless synthetic vitamin C is taken with some of the naturally occurring kind, it is not utilised by the body, and just flushed out through the urine, which appears to be consistent with the above. My question is: How are commercial vitamin D3 supplements obtained, an is there any way of distinguishing between synthetic, and natural types, as there is with vitamin B supplements? I refer you to a previous article: "VITAMIN D SUPPLEMENTS ARE UNSUITABLE!

(http://www.mercola.com/) Why Vitamin D Supplements Are NOT the Same as Sunlight", in the correspondence about which, near the foot of the webpage, it is stated that: "Vitamin D3 - cholecalciferol (animal based, generally naturally derived)". Somewhat reassuring, perhaps, but can anyone tell us more about this? In such an important matter, uncertainty is extremely undesirable.

Mechanism of action

Once vitamin D is produced in the skin or consumed in food, it is converted in the liver and kidney to form 1,25 dihydroxyvitamin D, (1,25(OH)2D) the physiologically active form of vitamin D (when "D" is used without a subscript it refers to either D2 or D3). This metabolically active form of vitamin D is known as calcitriol. Following this conversion, calcitriol is released into the circulation, and by binding to a carrier protein in the plasma, vitamin D binding protein (VDBP), it is transported to various target organs.[7]

The hormonally active form of vitamin D mediates its biological effects by binding to the vitamin D receptor (VDR), which is principally located in the nuclei of target cells.[7] The binding of calcitriol to the VDR allows the VDR to act as a transcription factor that modulates the gene expression of transport proteins (such as TRPV6 and calbindin), which are involved in calcium absorption in the intestine.

The Vitamin D receptor belongs to the nuclear receptor superfamily of steroid/thyroid hormone receptors, and VDR are expressed by cells in most organs, including the brain, heart, skin, gonads, prostate, and breast. VDR activation in the intestine, bone, kidney, and parathyroid gland cells leads to the maintenance of calcium and phosphorus levels in the blood (with the assistance of parathyroid hormone and calcitonin) and to the maintenance of bone content.[15]

The VDR is known to be involved in cell proliferation, differentiation. Vitamin D also affects the immune system, and VDR are expressed in several white blood cells including monocytes and activated T and B cells.[13]
