It is important for us to remember that there are companies producing supplements who are NOT doing the right thing.

Calling products 'natural' is easy, it does not mean anything, that is it has no (regulatory) required meaning

We need to make sure the companies whose products we buy, are using good manufacturing practices (GMP). How can this be done?

By asking FDA to do the right thing and make companies follow these practices. See the study on this page about Mfg Practices.

FDA pretends it has no power over supplements because an act of Congress (DHSEA) allowed dietary supplements to be handled differently than patented pharmaceutical medicines. But it did not tell FDA not to enforce basic GMP.

Here is the FDA statement page on dietary supplements, with their advice for the public. (It has taken almost 7 years for FDA to prepare their thoughts on how to handle dietary supplements). (Tips for the Savvy Supplement User)

Merck Manual explains vitamin deficiency and toxicity at

American Society for Nutritional Sciences information on vitamins and minerals:

A quote from Leonardo Da Vinci (ODE Magazine November 2007)

"Nature is so delightful and abundant in its variations that among trees of the same kind there would not be found one plant that resembles another nearby, and this is so not only of the plant as a whole but among the branches, the leaves and the fruit, not one will be found that looks precisely like another".

Ann's NOTE: Doesn't this speak to the idea that making herbs or other natural elements 'conform' is a bit absurd?

Ten Cautionary Statements from p 103 "Antioxidants against Cancer" by RALPH MOSS, author, advocate:

1. Do not take very high doses of vitamin A, D or E, except under a doctor's direction.

2. Do not take synthetic beta-carotene, especially if you smoke. Ann's NOTE: Please try everything you can to quit smoking).

3. Do not take high dose vitamin C as a single agent while taking either methotrexate or DTIC.

4. Do not take high-dose vitamin C supplements if you have a hereditary tendency to accumulate iron (hemochromatosis).

5. Do not take high-dose tangeretin, especially with tamoxifen.

6. Do not take NAC while you are taking cisplatin or Adriamycin.

7. Do not take zinc while you are taking cisplatin or carboplatin.

8. Do not take melatonin if you have leukemia or any other proliferative disease of the blood or lymph.

9. Do not take folic acid while you are taking methotrexate.

10. Have your progress checked by a holistic clinician.

Excerpted from "Doctor Yourself" newsletter Vol 4, No 13, June 4, 2004 (Andrew Saul, PhD):

"Why no new, large-scale studies of high dose selenium-vitamin E therapy?

Because drugless therapy is ignored by drug companies, and consequently remains unpromoted and unknown to physicians.

There is no money in products that cannot be patented. Children learn at an early age that mud pies don't sell. No investment is made, no research is done where there is no money is to be recovered.

Drug companies do not expect to find, nor do they want to find, a cure that does not involve a drug".

Please find other studies in the "Information by Cancer Type" section of "Relevant Studies".
