Vitamin D3 and Inflammation

Having a low amount of Vitamin D3 can be the cause of numerous diseases. Cancer being one of the big ones, and Arthritis being number two. People in the Northern hemisphere are very deficient in this vitamin. I started taking 5000 IU, but it said that people were given up to 21,000 IU with no ill effects. I told one of my friend about Vitamin D3, because she suffers from Rheumatoid Arthritis. She said it was a miracle, because of how fast it worked. She used to soak her hands in warm water to relieve the pain, because she did not want to go on prescription meds. The joints in her finger were sore to the touch, and now her fingers are pain free. She feels great!
