Americans spend enormous amounts of money on vitamins and mineral supplements in an effort to stay healthy or to improve their health. Unfortunately, unless a person has an actual vitamin or mineral deficiency, studies are just not finding health benefits. Sometimes there are even harms.

Physicians at the Northwestern University Feinberg School of Medicine weighed in on this issue. Their view: For most non-pregnant healthy Americans vitamin and mineral supplements are a "waste of money". There is no "magic set of pills to keep you healthy". Instead, a healthy diet and exercise are key.

However, they also say a pregnant women should consider taking a prenatal vitamin, especially folic acid. There are health benefits to folic acid supplements during pregnancy.

Basic conclusions: For non-pregnant persons without vitamin or mineral deficiencies, there is no evidence supporting the consumption of vitamin and mineral supplements in preventing cancer or cardiovascular (heart) health. Avoid beta carotene supplements (health harms) and vitamin E supplements.

What to do to maintain or improve health? Eat a healthy diet rich in fruits, vegetables, whole grains, legumes (beans), seeds, and nuts. Get enough exercise or physical activity. Don't smoke. Maintain a healthy weight.

Doing these things will also improve the gut microbiome (the community of microbes living in the gut), which is so important for good health.

Published on 2 Comments on Four Vitamin Studies Have Disappointing Results

The past year has resulted in disappointments for the vitamin and mineral supplement industry as study after study didn't find health benefits from routinely ingesting them. Instead, study after study found health benefits from eating a good diet, specifically one that has as few as possible highly processed foods, but lots of whole foods, and rich in whole grains, fruits, vegetables, nuts, seeds, and legumes (beans). And in this way, also high in fiber. Think along the lines of a Mediterranean diet.

The following are some of the studies finding no benefits to various vitamin and mineral supplements. Many found the results of the vitamin D studies especially disappointing.

In a massive new analysis of findings from 277 clinical trials using 24 different interventions, Johns Hopkins Medicine researchers say they have found that almost all vitamin, mineral and other nutrient supplements or diets cannot be linked to longer life or protection from heart disease.   ...continue reading "Four Vitamin Studies Have Disappointing Results"

A diagnosis of a lifelong progressive disease such as multiple sclerosis is one that everyone wants to avoid. So there is much speculation and research looking at what causes it and possible ways to avoid getting it. Some earlier research suggested that zinc  and iron may play a role (e.g., finding that zinc levels are lower in those with multiple sclerosis). Thus the results of this long-running study of more than 170,000 female nurses (Nurses' Health Study and Nurses' Health Study II) was informative.

The researchers found no association with intake of any of the following minerals (potassium, magnesium, calcium, phosphorus, iron, zinc, manganese, copper) and multiple sclerosis risk. As the researchers Concluded: "Our findings suggest that mineral intake is not an important determinant of MS risk.

In case you're wondering about what is protective - a number of studies have shown that people who get more sun exposure have a lower risk of MS.

From Science Daily: Do minerals play a role in development of multiple sclerosis?

Some studies have suggested that minerals such as zinc and iron may play a role in how multiple sclerosis (MS) progresses, once people have been diagnosed with it. But little was known about whether zinc, iron and other minerals play a role in the development of the disease. A new study shows no link between dietary intake of several minerals and whether people later develop MS.  ...continue reading "Mineral Supplements and Multiple Sclerosis"
