Vitamins and Minerals

Like water, carbohydrates, protein, and fats, and the enzymes needed to digest them, vitamins and minerals are essential to life.

Therefore, they’re considered nutrients, and are often referred to as micronutrients simply because they’re needed in relatively small amounts compared to the 4 basic nutrients.

Recommended Dietary Allowances (RDAs) were started in 1941 by the National Academy of Sciences’ U.S. Food and Nutrition Board as a standard for the daily amounts of vitamins and minerals needed by a healthy person.

These RDAs were the basis for the U.S. Recommended Daily Allowances (U.S. RDAs) adopted by the Food and Drug Administration (FDA).

The U.S. RDA used to be the term used on food labels.

However, the Nutrition Labeling and Education Act and the Dietary Supplement Act of 1992 required a change in food product labeling to use a new reference term, Daily Value (DV), which began to appear on product labels in 1994.

Today you can look at any food or dietary supplement label and see the percent DV of all essential nutrients contained in the product.

DVs are made up of 2 sets of references:  Daily Reference Values (DRVs) and Reference Daily Intakes (RDIs).

DRVs are a set of dietary references applied to fat, saturated fat, cholesterol, carbohydrate, protein, fiber, sodium, and potassium.

RDIs are a set of dietary references based on the Recommended Dietary Allowances for essential vitamins, minerals and protein.

The term RDI replaces U.S. RDA.

In 1998 the Food and Nutrition Board published new guidelines for healthy eating and called them Dietary Reference Intakes (DRIs).

These can be used for planning and assessing diets for healthy people.

The goal is to have these guidelines, which make up the DRI, replace the old RDA standard.

The amounts of these nutrients defined by the DRI give us about twice the amount needed to ward off vitamin deficiency diseases like beriberi, rickets, scurvy, and night blindness.

What they don’t account for are the amounts needed to maintain maximum health, rather than borderline health.

Moreover, they’re not good at providing an individual’s need but rather population norms.

Scientific studies have shown taking dosages of vitamins above the DRIs helps our body work better.

The DRIs therefore aren’t very useful for determining what our intake of different vitamins should be.

We prefer to speak in terms of optimum daily intakes (ODIs) – the amounts of nutrients needed for vibrant good health.

This means consuming larger amounts of vitamins than the DRIs.

The nutrient doses we recommend are ODIs.

By providing our bodies with an optimum daily amount of necessary vitamins, we can enhance our health.

The dosages we outline will enable you to design a vitamin program custom-tailored for you.

Many nutrients with a DRI also have a corresponding Tolerable Upper Level of Intake (UL), which is higher than the DRI but found to be safe.

Don’t take more than the UL for any nutrient (unless your health care provider recommends you do) because it’s not safe to do so based on what we know today.

The ULs are constantly under scrutiny.

For example, scientists have called for the FDA to increase the UL for vitamin D.
