You should check out a web site ceri.com There are a huge amount of supplements that can be taken that really help. My husband is taking E, C, pycnogenol, coq10, sun chlorella a, multi-mineral, cell guard, nadh, liq. deprenyl to name some. He feels much better, is more active and has actually been able to reduce his sinemet a bit. Of course, check with people who know and your own intuition and feelings about this. Good luck. Den
