Haven't tried it myself yet. However, there is a children's section as well as adult. I presume it is gentler.

I think the GI factor is probably the most overlooked piece of the puzzle. Back on BT we polled about 15 or so of us and fully half remembered constipation as a problem when they were kids. That seems very high for a young active population. And constipation is a common plague for PWP.

Then add in inflammation, also a big factor for PD. And the smae things that affect the endothelial cells of the BBB also affect the similar barrier at the GI interface.

So we have all that "sludge" full of toxins moving at a snail's pace along a leaky pipe. We wouldn't want that pipe crossing our front lawn! Yet, it leaks into the streams that end up in our brain.

It doesn't take a rocket scientist....
