I have met and believe in Bob Barefoot! His attention to detail and the extra ingredients that he puts in his authentic supplements is much appreciated!
Just make sure that any product you purchase has his picture on the bottle. There are a few unscrupulous companies out there that try to trick you into believing that theirs is the real deal! I've been fooled so be warned!
We have been using his products for over 10 years and never get sick!
I use the top of the line coral calcium product that he offers, called Bobs Best Coral Calcium 2000 and buy it from his distribution company who are called Coral Calcium Direct.
Hope this helps you!
