Sincerely many thanks. I started taking MP capsules (1100 mg ea.) x2 a day three days ago with no noticeable effects. Percent of L-Dopa level is unknown nor listed on the bottle. I really had my hopes up trying this supplement but so far there hasn't been anything positive to say. I would appreciate hearing any opinions regarding using Mucuna Pruriens supplements. The brand name on the bottle is 'Jiva Botanicals'. Again, thank you...
