Michelle Averill, the associate director of the University of Washington's Graduate Coordinated Program in Dietetics, said generally Americans are "doing fine" with getting enough vitamin B, particularly if they are eating grains fortified with the nutrient. Vitamin B helps convert food into energy, boosts immunity, and assists in making new cells, according to Harvard Medical School. There are several different types of vitamin B, including thiamin (B1), riboflavin (B2), and cobalamin (B12).

"We always need enough, and sometimes more is harmful." Typical American diets contain enough vitamin B, excluding B12 "When people think about vitamins, it's never more is better," Vollrath said. A 2013 review of placebo-controlled trials did not find evidence vitamin C supplementation prevents 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 length, but won't stop the virus. The two nutrients are found in a variety of fruits and vegetables, and it doesn't take much to get your daily requirement: just one orange has most vitamin C you need for the day, per Medical News Today.Ä«ecause of vitamin C's immune boosting properties, some people take the supplement to prevent colds. In 2018, the US Food and Drug Administration stopped requiring sellers to label the daily value of vitamin C and vitamin A on nutrition labels because of how rare deficiencies of these vitamins are. Vitamin C supplements might reduce the severity or length of a cold, but overtaking supplements won't help People with deficiencies diagnosed by a doctor, or those who have limited diets due to food allergy or intolerance, could require supplements, per Laing. Though Americans typically get enough vitamins A, C, B and zinc through the Western diet, experts said people should strive to get every nutrient through a balanced diet. Insider spoke with three dietitians to understand which vitamins and minerals Americans are typically eating enough of through their diet, makingĀ supplements unnecessary. Plus, Americans may not realize they are getting enough vitamins and minerals through their diet already.
