December 28, 2023 – The marketplace for Dietary supplements – vitamins, minerals, botanicals, herbs and other products promoted as ways to allow you to feel higher, look higher, perform higher, sleep higher and stay healthy – are booming, and still booming not over. In 2021, U.S. consumers spent greater than $48 billion on dietary supplements; This number is anticipated to extend by greater than 5% annually over the following five years.
The industry grew from approx 4,000 products in 1994 to 80,000 in 2016. At least half of adults within the U.S. take dietary supplements, in keeping with the 2021 federal agency Statistics. Three-quarters of people that responded to a 2023 consumer survey by the Council for Responsible Nutrition, the trade association that represents complement manufacturers and ingredient suppliers, said they take supplements.
Despite this enthusiasm, experts worry concerning the negative effects of megadoses and point to the dearth of evidence supporting the advantages of many supplements. Others say more government oversight is urgently needed. Currently, the FDA's role in regulating dietary supplements typically begins after the product is in the marketplace.
Supplement user profile
While some consumers are seasonal or occasional users, others are avid complement takers like Suzanne Bank, an interior designer in Studio City, California. Her regular supplements include Vitamin C, Apple Cider Vinegar for digestion, Trimagnesium for healthy muscle function, and Cat's Claw for brain health.
“They helped me move on and live an active life,” said Bank, who said she is past the “typical” retirement age but still runs her own business. “I’m healthy, I don’t get sick and I look much, much younger than my age.”
Bank said she has experienced no in poor health effects, even after greater than 40 years of recurrently taking supplements.
So which supplements work?
According to the FDA Dietary supplements might help improve or maintain overall health and help people meet day by day needs for essential nutrients. It also states: “While the benefits of some supplements are well established, other supplements require further study.” It warns that supplements should replace a wide range of foods which are necessary to a healthy weight loss program.
“Most people think of dietary supplements as, at worst, harmless prevention products,” said Jeffrey A. Linder, MD, MPH, chief of general internal medicine at Northwestern University Feinberg School of Medicine in Chicago. But they are usually not all the time harmless. Linder said: “I'm more concerned about people becoming distracted from things that actually help them stay healthy, like exercise, eating a healthy diet and maintaining a healthy weight,” Linder said.
While there isn’t any consistent reference on which supplements are price taking, various organizations and researchers try to summarize the evidence and draw conclusions. Recently, the US Preventive Services Task Force issued recommendations on the evidence for dietary supplements to stop heart problems (diseases of the guts and blood vessels) and cancer.
Linder co-authored one editorial to follow these recommendations. In summary, the working group concluded that “there is insufficient evidence for virtually all dietary supplements to prevent cardiovascular disease and cancer” and that vitamin E and beta-carotene are strongly really helpful for the prevention of those diseases.
Overall, Linder says there may be a few of the strongest evidence that prenatal folic acid supplements prevent birth defects, citing a previous recommendation by the duty force.
While the Task Force rating of “I” for insufficient evidence for many dietary supplements doesn’t represent a vote for or against use, Linder said, current evidence shows that a multivitamin is more likely to help reduce the danger of dying from heart disease have a use Be a small one.
Vitamin D supplements are popular amongst individuals who wish to improve bone health, reduce cancer risk and reduce inflammation. However, it’s difficult to prove that vitamin D supplements help those that are usually not naturally vitamin D deficient, Linder said, noting that the duty force found no evidence that vitamin D reduce the danger of cancer or heart problems.
“I think there are a lot more people taking vitamin D [supplements] more unnecessary than there are people who benefit from vitamin D supplementation,” he said. Likewise, the duty force found no evidence that vitamin C reduces the danger of cancer or the danger of dying from cancer.
What works? Research on dietary supplements for musculoskeletal health
In a special issue of the magazine nutrient, Researchers submitted 13 studies and 4 study reviews and concluded that a wide range of dietary supplements might help improve bone and muscle health in individuals with and without certain diseases.
A collection of their results:
- Vitamin D may reduce pain in patients with fibromyalgia and other painful conditions.
- Creatine can provide athletes a bonus when sprinting.
- Polyphenols can improve sports and exercise performance and speed up recovery after exercise.
- Collagen can improve joint health.
Side dishes of the day
In recent years, “beauty” supplements that promise to enhance skin, hair and nails have grow to be increasingly popular doubling According to a national health survey of nearly 41,000 people from 2012 to 2020.
Consumers needs to be careful when taking these medications, said Rajani Katta, MD, a Houston dermatologist who serves on the honorary faculty of the University of Texas McGovern Medical School and Baylor College of Medicine in Houston. Katta published information about any such dietary complement. For example, biotin, which complement manufacturers claim has positive effects on hair and skin health, can interfere with tests of thyroid and heart function, she said. Heavy metals have been present in collagen supplements.
“If you are taking a supplement high in biotin, you need to tell your doctor,” Katta said. “It could interfere with testing.” Avoid supplements that list “proprietary blends” as an ingredient because this doesn’t let you know what ingredients are included.
Solution: More control?
The Dietary Supplement Health and Education ACT of 1994, or DSHEA, established regulations for dietary supplements. Thereafter, the FDA typically doesn’t review dietary supplements before they arrive to market, and manufacturers of dietary supplements are usually not required to supply basic product information, reminiscent of names or ingredients, to the FDA before offering them on the market.
Therefore, the FDA relies totally on postmarketing surveillance to watch product safety. It restricts use or orders a recall only when there may be evidence that a product or ingredient is unsafe.
According to the statement, the growing marketplace for dietary supplements means increasing risk Experts are pushing for it more supervision. When formulating the necessity, researchers write within the AMA Journal of Ethics cited a study that found the FDA's CFSAN Adverse Event Reporting System (CAERS) received greater than 15,000 reports of health problems related to dietary supplements, including 339 deaths and nearly 4,000 hospitalizations.
In 2022, bipartisan laws to strengthen oversight of the dietary complement industry was introduced within the Senate Invoice, by Senate Majority Leader Dick Durbin (D-IL) and Senator Mike Braun (R-IN), would require dietary complement manufacturers to list their products with the FDA. It was introduced in April 2022 and referred to the Health, Education, Work and Pensions Committee.
Industry views
The Council for Responsible Nutrition counters that there is robust evidence to support using many dietary supplements. In 2022 it published a report, surcharges for saving, about the price savings in healthcare through using targeted dietary supplements for specific diseases. Among other things, they found a profit for omega-3 fatty acids in cardiovascular diseases, vitamin D in osteoporotic fractures and magnesium in cardiovascular diseases. For example, vitamin D with calcium reduced the danger of a fracture by 14%.
The industry supports the thought of greater oversight, said Steve Mister, CEO and president of the Council for Responsible Nutrition. For example, he said his organization strongly supports Durbin's bill, which might require dietary complement manufacturers to list their products with the FDA. “The basic idea of the bill is something that CRN strongly supports.”
It's an issue, he said, that the FDA has no way of knowing what number of dietary supplements are in the marketplace. The Durbin bill would have established some type of registry, not for premarket approval, but for access to details about products, which Mr. Herr sees as something the FDA needs.
The existing law will probably be 30 years old in 2024, Mr. stressed, and it’s overdue for an overhaul to bring about reform and maintain security.
