Yes, I've been doing a bit of research too. Apart from everything you mentioned, it's blooming expensive and contains milk thistle, green tea extract and turmeric (and something else I can't remember). I drink green tea and use turmeric a lot in cooking already, so will not be trying this product out.
I will be eating lots of broad beans and their pods, when they're ready though.......supposed to contain small amounts of natural Levadopa. My neighbour has an allotment and brings me loads of fresh produce as it ripens. Unfortunately I'm not that keen on broad beans, but when needs must.......
Thanks for replying.
