TUESDAY, Oct. 11, 2016 (HealthDay News) -- Traditional multivitamins are falling out of favor among Americans, while supplements such as vitamin D, fish oil and probiotics are gaining ground, a new study finds.

Researchers found that between 1999 and 2012, Americans' overall use of supplements remained stable. Slightly more than half of adults said they took vitamins, minerals or some other type of dietary supplement.

What's changed are the products of choice.

Multivitamins and many individual vitamins and minerals are less popular, as are botanicals such as echinacea, ginseng and garlic extracts, the investigators found.

On the other hand, more people are using vitamin D, omega-3 fatty acids and probiotics -- "good" bacteria said to benefit the digestive system.

Researchers said the findings make sense.

"I did expect to see that vitamin D use would go up, and that fish oil would go up," said lead researcher Elizabeth Kantor, an epidemiologist at Memorial Sloan Kettering Cancer Center in New York City.

That's because both have been the focus of a lot of research and media attention in recent years, Kantor pointed out.

Some studies, but not all, have suggested fish oil pills can curb the risk of heart attack and other cardiovascular trouble. And studies have hinted that vitamin D could be protective against a range of ills, from cancer to diabetes to multiple sclerosis -- though clinical trials testing those ideas have yet to be finished.

The drop in multivitamin use was less expected, Kantor said. But it also makes sense, she added.

During the study period, a number of studies questioned the value of multivitamins when it comes to preventing major health conditions.

Similarly, antioxidants -- such as vitamins C and E, and beta-carotene -- were once a hot topic. Early studies suggested they might battle ills like heart disease and cancer.

But clinical trials later found either no benefit, or even potential harm, from antioxidants, Kantor's team pointed out in the new report.

The current findings are based on almost 38,000 U.S. adults who took part in a nationally representative government health survey between 1999 and 2012.
