Vitamin D is very important and a deficiency has been linked as a cause of MS. Also, it is important to get your hormone levels checked. Just treating hormone imbalance can help with MS symptoms. Vitamin D Deficiency is also linked to certain types of cancers.   Numbness,tingling, slow motor skills and digestive issues are common with vitamin d deficiency and as Lisa said can mimic MS symptoms.   The homeopathic doctor has me taking 4,000 IU a day right now of D3. She says that the BIO-D-MULSION Forte from Biotics Research Corporation is one of the best on the market providing 2,000 IU of vitamin D3 per drop. D3 has been found to be the most effective to take and is considered the more absorbable the then D2. I'm sure that it can be found online.   The vitamin d council recommends a persons levels be between 35 to 65 with 50 being optimal especially in the winter months. On the other hand 5 to 10 minutes in the sun 3 times a week can help with these levels also.   Just because you go to the doctor and they say your levels are in range at 32 doesn't mean that is the best level for you. That is not the optimal level only a recommended level. Do whats best for your body. The vitamin D assciation says you can take 10,000 IU a day with worrying about toxicity issues. Please get your levels checked periodically since taking too much vitamin d can do as much damage as not taking or getting enough.
