I hope you are keeping well. I thought you may be interested in my recent findings. I have been looking at the different strengths of Mucuna in the various products. The organic powders are not tested for amounts but I have been told by a company this is usually around 4% as opposed to the extract powders which can vary from 98% to 40%. Discussing this with my neurologist he advised that for a therapeutic dose; an amount of up to 2grams 3 times a day would be required. I am going to try a product from nutrivitashop.com that is popular on other forums, this is 98% l dopa with an 1/8 tsp being approx 500mg.
Best wishes Steph
