Preventing Pharmaceutical-Induced Nutritional Deficiencies

Up to 30% of drug side effects are caused by drug induced nutrient deficiencies. Here we examine common drugs, the vitamins and minerals they deplete, and how to ensure adequate stores of these critical nutrients.

Scientifically reviewed by: Dr. Gary Gonzalez, MD, in October 2024. Written by: Life Extension Editorial Staff.

While pharmaceuticals have lifesaving benefits, many of these medications can have serious side effects, ranging from cardiac arrest to suicide.

Millions of Americans suffer from an almost completely ignored epidemic of drug-induced nutrient depletion that can cause grave health problems. Perhaps 30% of pharmaceutical side effects are the direct result of these drug-induced nutrient deficiencies. In other words, a drug “robs” you of one or more nutrients or other helpful substances, and this lack of nutrients causes additional side effects. In a sense, the drug acts as an “anti-vitamin pill,” taking away the substances you need for good health. Thus, nutrient depletion caused by the drugs—rather than the drugs themselves—is often directly responsible for many of the side effects associated with pharmaceuticals.

Among the most common drugs linked to nutrient depletion are oral contraceptives, cholesterol-lowering statins, and antibiotics. These and many other over-the-counter and prescription medications can interfere with your body’s ability to digest, absorb, synthesize, or make use of certain nutrients, leading to nutrient deficiency-related “side effects.”

The only solution to averting drug-induced nutritional deficiencies is to replace the depleted nutrients through nutritional supplements, dietary sources, or both. In this article, we examine some commonly prescribed drugs and the vitamins, minerals, and other substances they are most likely to deplete.

Drugs Are Helpful, But . . .

Pharmaceutical drugs perform many miracles every day, from controlling diabetes to containing virulent infections. However, it is important to remember that all drugs—every single one of them, even the simple and ubiquitous aspirin—have side effects, and that some of these side effects can be ameliorated or even eliminated by restoring the missing nutrients.

Information on other drugs and the nutrients they deplete is available in The Side Effects Bible: the Dietary Solution to Unwanted Side Effects of Common Medications by Frederic Vagnini, MD, and Barry Fox, PhD (Broadway Books, 2005).
