Many commonly prescribed drugs cause nutrient depletions, which can cause or contribute to a wide variety of health problems. I created a Quick Reference Guide that lists the nutrients depleted by the most commonly prescribed drugs. The information comes from scientific studies I referenced in the two seminal books I’ve written on the topic of drug-induced nutrient depletions. This is an indispensable resource for professionals, practitioners and patients wanting to address this severe side effect of popular pharmaceutical medications.
