I just saw the MS Specialist, and she made an interesting recommendation. She recommended that I go on D3 4000-5000 units and both of my girls go on it as well.
Research has proven that it can help prevent relapses in people with MS . . . Interesting tidbit I learned today.
She also recommends that both of my girls take it, too. There's a little bit more of a chance that they can develop the disease, too.
