Nutritional Supplements

Nutritional supplements are not really about science | Life Examined - KCRW

A recent study found that 81% of adults in the U.S. between the ages of 35 and 54 take dietary supplements, and that 76% of all Americans take some kind of vitamin or mineral. Nutritional supplements are big business — the industry is worth $40-50 billion a year, with the average American investing between $50-60 dollars a month on an array of tablets to help with anything from brain health to hair loss to anxiety to curing COVID.

Nutritionist and author Dr. Marion Nestle says that unless there's a medically identified deficiency, there’s no scientific evidence to show that supplements make “healthy people healthier.” Most people, Nestle says, need relatively few essential nutrients to be healthy, but there’s no doubt that people feel better if they take supplements. Nestle says we should be skeptical of any medical claims made by these products, but realize that psychology plays an important part in our health.
