Query: Hmmm...this book is fishy

I agree with Catherine Connell, the nurse who wrote a review below. This book is just preying on the gullible, plain & simple. Besides--there are hundreds of ways a person can fulfill his or her RDA of calcium CHEAPLY & EASILY just by eating calium-rich foods like green, leafy vegatables, broccoli (1 c.=1 c. of absorbable calcium in milk), soy products, beans, cabbage, almonds & most nuts, sesame seeds, salmon, etc. And don't forget your daily multi-vitamin, & you'll be in good health. Sensible eating, people! You don't have to waste a paycheck on another bottle of supplements! I for one am by-passing the nonsense I read in this book.
