There are two things contributing. MVP is associated with low carnitine and magnesium levels. I use the acetyl form of carnitine. I think this is much more effective than regular carnitine. If I had MVP and FMS, I'd take two to three grams of carnitine per day for two to three months, then drop it to one gram per day.
Low thyroid is also a major player.
I have two formulas that I've put together for people with FMS and people in general. As I noted before, the company donates my entire share of these profits to charity, at my request. Most of the nutritional deficiencies can be taken care of by using my foundation formula, one and a half scoops per day, adding coenzyme Q10, essential fatty acids, and NADH can also help. For sleep, I have my sleep formula, which is a wonderful natural product. Three to four tablets a night can help sleep quite a bit.
