Mucuna- Ron Hutton and I tested this one somewhat, both the raw powder and a standardized extract form. It definitely worked, sometimes too well (dystonia) in the case of the extract. It is on my list to retry the powder as I, too, see an advantage in "dirty" drugs. Mucuna has a lot more than ldopa in it. The biggest problem was that it stained everything black.

Acetyl-L-Carnitine plus Alpha Lipoic Acid plus L-Carnosine- I have had measurable success with this combination. Purportedly the combo boosts mitochondrial function. In my case, I used a timed balance on each foot to test before and after. As I recall, time on each side increased by a factor of five within 48 hours.

Panax Ginseng - "Red" processing method - Although this one may have been affected somewhat by my potassium problem, at least two others have reported similar results. A definite lessening of symptoms and purported protective action.
