We have been taking powdered mucuna for over a year in addition to our regular sinemet dosage. It definitely crosses the BBB, and faster. It also can be taken even if you have eaten, a huge plus for us. We take mucuna several times a day, beginning first thing in the morning to get going.

We do not take a pill, mucuna, we take the organic mucuna powder from a couple of places from which we buy it in bulk one pound bags. One place is Banyan Botanicals, the other I can't remember since it is new for us. Both seem reputable and we don't have any commercial ties to either, just sharing where we get ours.

Sometimes we skip the sinemet because the mucuna has hit so well. Again, not recommending anyone else do that, just sharing what we've done.

A one pound bad of mucuna powder is about $23.00 and we buy several at a time and freeze all but the one we open and use. At 1.5 teaspoons per "dose", one pound lasts a long time
