Recent studies have indicated that Vitamin D deficiency can cause muscle weakness and pain in children and adults. In a cross-functional study of 150 patients referred to in a clinic in Minnesota for the evaluation of persistent muscle and bone pain, 93 percent had vitamin D deficiency! Muscle pain and weakness were prominent symptoms of vitamin D deficiency in a study of Arab and Danish Muslim women living in Denmark. Another trial found that supplementation of elderly women with 800 IU per day of vitamin D and 1200 milligrams per day of calcium for three months increased muscle strength and decreased the risk of falling by almost 50 percent compared with supplementation with calcium alone. This is an extremely significant finding and a compelling case for supplementation.
Do you take a vitamin D supplement?

Yes I do take vitamin D..my levels are very low and I must take the prescrption for 8 weeks plus a under the tongue vitamin d tablet with B-12. It seems that my levels go up and down.
I had the lowest levels my dr had ever seen- and I never wear sun screen and live in Australia. I was pretty shocked, working at getting my levels up to normal…
