How much is in a supplement?
A 2022 analysis of 16 US Mucuna supplements detected no levodopa in one product and 2–241 mg per serving in the others. Neither carbidopa nor benserazide was detected. These sampled products therefore differed substantially from one another and from combination medicines. 1
