What you can buy and where is different in different places. I buy my turmeric in powder form (which is probably not a good as the fresh turmeric root), from any store that supplies asian, especially Indian food products. I also buy sunflower lecithin powder usually on-line form whichever supplement supplier has it at the moment. Most of it originated in Ukraine but that has become difficult in the last couple of years. As for exercise, the answer has to be "It depends". I have always been active and do about 1 hour per day. What it depends on is how active you have been and your age as well as your appetite for exercise. Half an hour per day or even 3 times a week would probably be the minimum for me but might easily be the maximum for you.
