4 Unnecessary Supplements You’re Probably Getting Enough Of In Your Diet Already, According To Nutrition Experts

  • Vitamins A, C, B and zinc are nutrients that Americans generally get enough of through their diets.
  • Nutrition experts say Americans should try to get all nutrients from food rather than through supplements.
  • Taking extra vitamin C and zinc probably won’t prevent a cold, and excess amounts are flushed out.

The supplement industry is exploding, but nutrition experts don’t recommend getting your vitamins and minerals from pills.

Supplement sales hit a record high $55 billion in sales in 2020, and the industry has seen huge gains since the start of the COVID-19 pandemic.

Emma Laing, a clinical professor at the University of Georgia and a registered dietitian, said most healthy adults get their nutrients from food rather than supplements because food provides biochemicals and fiber that don’t come from food. of a pill.

“Foods like whole grains, vegetables, and legumes are generally considered affordable foods that are also nutrient-dense,” Laing told Insider. “It would be difficult to manufacture a supplement that mimics the exact nutrient profile of these foods and provides the same health benefits.”

Plus, Americans may not realize that they already get enough vitamins and minerals from their diets. Insider spoke with three dietitians to understand which vitamins and minerals Americans typically get enough of in their diets that make supplements unnecessary.

Although Americans generally get enough vitamins A, C, B and


through the Western diet, experts say people should strive to get all the nutrients through a balanced diet. People with deficiencies diagnosed by a doctor, or those on a restricted diet due to a food allergy or intolerance, might need supplements, according to Laing.

Vitamin C supplements may reduce the severity or duration of a cold, but going over the supplements won’t help

In 2018, the US Food and Drug Administration stopped demanding vendors to state the daily value of vitamin C and vitamin A on nutrition labels due to the rarity of deficiencies in these vitamins. Both nutrients are found in a variety of fruits and vegetables, and it doesn’t take much to meet your daily needs: a single orange contains the most vitamin C you need for the day, per Medical News Today.

Due to the immune-boosting properties of vitamin C, some people take the supplement to prevent colds. Kirstin Vollrath, a registered dietitian and professor at the University of Houston, said taking vitamin C and zinc together at the start of a cold might reduce its symptoms or its duration, but would not stop the virus. A balance sheet 2013 placebo-controlled trials have found no evidence that vitamin C supplementation prevents colds.

“Our bodies are much more sophisticated than we realize,” Vollrath said. “Your body knows how much vitamin C it needs, and once it has enough to function, the rest is going to be excreted mostly through urine.”

Most Americans Get Enough Vitamin A, But Supplements Cause Overdoses

As with vitamin C, the FDA has stopped requiring food manufacturers to label the daily percentage of vitamin A due to the rarity of deficiencies.

Vollrath said that globally, vitamin A deficiency is a common cause of blindnessthe average Western diet contains enough nutrients.

In fact, Vollrath said Americans are more likely to overdo it with vitamin A. Vitamin A toxicity usually occurs when taking too many supplements and can cause nausea, headaches, and blurred vision.

“When people think of vitamins, it’s never more is better,” Vollrath said. “We always need enough, and sometimes more is harmful.”

Typical American diets contain enough vitamin B, excluding B12

There are several types of B vitamins, including thiamin (B1), riboflavin (B2), and cobalamin (B12). Vitamin B helps convert food into energy, boosts immunity and helps make new cells, according to Harvard Medical School.

Michelle Averill, associate director of the University of Washington’s Graduate Coordinated Program in Dietetics, said Americans are generally “doing well” with getting enough B vitamins, especially if they eat nutrient-enriched cereals. . Averill said research has indicated there is “very little benefit” to taking vitamin B supplements.

Vitamin B12 is a different story, Averill said, because vegetarians and vegans might not get enough of the nutrients because they’re mostly found in animal products. Vitamin B12 deficiencies can cause anemia, sensory problems and nerve damage.

Adults usually get enough zinc, and taking the mineral won’t stop a cold.

Averill said young children can benefit from more zinc, but deficiencies of the mineral shouldn’t concern most adults.

“We’re not really deficient,” Averill said. “There’s very little evidence to suggest you could take it and prevent things.

She said many people have tried taking zinc supplements to prevent or minimize a cold. A recent analysis of 28 controlled trials found that zinc had a moderate to no effect on alleviating symptoms of a cold, although it may shorten the duration of symptoms.

But according to Averill, the zinc needs to be in the body before exposure to the virus to have the best results. Additionally, taking zinc supplements through nasal sprays can cause permanent loss of sense of smell, according to Mayo Clinic.

Some populations may still need supplements for their health

Although most healthy Americans wouldn’t benefit from supplements like vitamin C, vitamin A, vitamin B and zinc, Laing said there are groups of people who might need them. Groups include people with a deficiency diagnosed by a doctor, those with a restricted diet due to a food allergy or intolerance, infants, and people planning a pregnancy or who are pregnant. Certain health conditions and medications may also require supplementation, according to Laing.
