RDA's vs Optimal Nutrition

As noted previously in the American Medical Association (A.M.A.) Speaks Out page, Recommended Daily Allowances (RDA’s) do little or nothing to prevent against our epidemic of chronic degenerative diseases. RDA’s were first introduced in the 1930’s, with minor changes later, for the purpose of reducing scurvy, rickets, and pellagra. They did a very good job for what they were intended.

Today, however, RDA’s are a confusing and misleading standard, causing many people to think that if they receive the RDA levels of certain vitamins, they're doing all that's recommended. This is clearly false and damaging to a confused and suffering population.

Today, we live in a sea of pollution. Air pollution, contaminated sources of water, radiation, over-processed foods, soils that are depleted of their critical trace elements, countless new toxic chemicals every month, and more and more prescriptive drugs. Couple these factors with less than adequate lifestyles and growing levels of psychological and physical stress, and you can see why the AMA report recommends supplements for virtually everyone.

The chart below illustrates what science has shown to be “Optimal Intakes” versus the “Current RDA” levels. You can see why RDA levels are ineffective and misleading.


Current RDA

Optimal Intake


Vitamin A

5,000 IU

15,000 IU


Vitamin C

59.9 mg

1,300 mg


Vitamin E

30.0 IU

450.0 IU


Vitamin B1

1.5 mg

27.0 mg


Vitamin B6

2.0 mg

27.0 mg



70.0 mcg

200 mcg


For reasons explained in more detail elsewhere within this site, it is virtually impossible to get all the nutrients we need from our food today. As an example of how difficult it is to obtain optimal amounts of nutrients from a typical diet, consider what you must eat to receive 450 IU, the amount of vitamin E contained in a daily dosage of a top grade multivitamin:

Food To Obtain 450 IU Of Vitamin E

Wheat germ 4.5 lbs

Almonds 3.0 lbs.

Spinach 38 lbs.
