<<Disclaimer: Verify this information before applying it to your situation.>> To Stephanie in Colorado: I understand your situation and the need to find some help. However, health fraud, which includes nutrition fraud, is big business. There are many quack tests which claim to test the absorption rate of vitamins and minerals. It is difficult to determine the absorption and such tests are few and far between. While the term naturopath sounds reassuring, they are usually physicians who practice alternative ways of treatment, whatever that means. Just watch your pocket book. If you really want to know about absoprtion of vitamins and minerals, see a dietitian. Kevin
