About a year ago, a therapist suggested vitamin D for my chronic, nonspecific musculoskeletal pain. She recommended 4,000 IU of vitamin D3 daily. I got a little better but not much, and didn't associate it with vitamin D supplementation at the time. Then about a month ago I heard about the Vitamin D Council, a non-profit group of physicians and research scientists, and I went on their website.
Knowing from a recent blood test that I am somewhat deficient in vitamin D, and based on what I was reading, I immediately began taking 8,000 IU of D3, and what an improvement!
In just a few weeks I am almost completely pain-free in the neck, shoulders, hips and knees. I don't believe it is a coincidence because I've been dealing with muscle pain for 6 years now. I will drop back to the Council's recommended dosage in the next few months, at which time I can get some of my vitamin D from the sun.
If there really is a magic bullet, it could very well be vitamin D. It helps just about every aspect of the human body. If you don't spend much time outside, are in the habit of slathering on sunscreen, or if you live north of 35 degrees latitude, you are probably low on D. Please be aware that although this research appears to be solid, and I know for certain it has helped me, it isn't yet mainstream and differs considerably from government recommendations. It is important to have your vitamin D level checked so you have some idea of how much you need. It's also important to know that vitamin D supplements must be D3, which is cholecalciferol, the same thing our bodies make from sunshine.
