More Than half of American adults take multivitamins and other dietary supplements, according to new statistics from the Centers for Disease Control and Prevention (CDC).

The use of dietary supplements is steadily growing in the US, the figures show.

“This report indicates high use of dietary supplements in the US adult population during the past 20 years, with over 40 percent of adults using one or more dietary supplements during 1988-1994, and over one-half of adults using supplements during 2003-2006,” authors from CDC wrote.

Multivitamins are among the most commonly used supplements with about 40 percent of Americans saying they have used them between 2003 and 2006.

Women are more likely than men to take at least one dietary supplement. In particular, calcium consumption has sharply increased with 61 percent of people taking a supplement with calcium in 2003-2006, compared to 28.2 percent in 1988-94.

In addition, consumption of vitamin D has shown a high increase, especially in women older than 60, as 56 percent of them get it through supplements.

On the other hand, consumption of folic acid, which is highly recommended to pregnant women for prevention of birth defects, showed no significant change over the same period at around 32 percent to 34 percent.

As dietary supplements often contain nutrients equal to or higher than the amounts recommended for intake and may pose health risks, tracking their usage is important for experts and health authorities.

"Because a high proportion of the US population uses dietary supplements, it is essential for surveys and studies that assess nutrient intake to collect information on these important contributors.”
