Credible supplements have peer-reviewed scientific literature that supports their use and effectiveness. Also, make sure the recommended dose is backed by science. If it is, it will also be discussed in supporting studies. More doses don't always equate to better results, so be careful with mega doses.
Claims of nutrient deficiency describe a benefit related to a nutrient deficiency disease, for example: “Adequate intake of vitamin B12 prevents pernicious anaemia. But these statements should also indicate how widespread the disease is in the US. UU. These claims are not previously approved by the FDA, but the manufacturer must notify the FDA within 30 days of the supplement being marketed, and they must be able to prove that the claim is truthful and not misleading by supporting clinical studies.
Check if the product contains enough nutritional ingredient. Does the amount match the amount that has been shown to be effective in scientific studies?. Its creators do not have to prove that they are safe or effective. Let's talk about some of the pitfalls of using supplements and how you can improve your chances of getting a pill that does what it's supposed to do.
Drugs must be approved by the FDA before they can be sold or marketed. Supplements do not require this approval. Supplement companies are responsible for having proof that their products are safe and that the claims on the label are truthful and not misleading. However, as long as the product does not contain a “new dietary ingredient” (one introduced since October 15, 1999), the company does not have to provide this safety evidence to the FDA before the product is marketed.
To find out if a product has been tested, see the Supplement Information panel. You'll know what the label says is what you get. Finally, always tell your doctor about any vitamins or supplements you plan to take, especially if you have a health condition or take regular medications. The FDA is not authorized to review dietary supplement products for safety and effectiveness before they are marketed.
The FDA has the authority to challenge supplement manufacturers who make drug-like claims and to recall products (like the ones above) that are clearly unsafe, but they only have the budget to pursue a handful of companies each year, and their safety reporting system is clearly inadequate. Popular supplements include vitamins D and B12; minerals such as calcium and iron; herbs such as echinacea and garlic; and products such as glucosamine, probiotics, and fish oils. In a supplement industry survey, 85% of Americans agreed that they were confident in the safety, quality, and effectiveness of supplements. Some supplements can help ensure that you get enough of the vital substances your body needs to function; others can help reduce the risk of disease.
USP is a non-profit organization that sets out what CR experts say are the most widely accepted standards for supplements. Unlike medicines, supplements are not allowed to be marketed for the purpose of treating, diagnosing, preventing or curing diseases. The Dietary Supplement Label Database, a project of the National Institutes of Health, has all the information found on the labels of many dietary supplement brands marketed in the United States. Manufacturers and distributors of dietary supplements are responsible for ensuring that their products are safe BEFORE they go to market.
Certain supplements come in pills because they stop working or become dangerous if they come into contact with stomach acid. Dietary supplement labels must include information about the name and location of the manufacturer or distributor. Products sold as dietary supplements come with a supplement information label that lists the active ingredients, the amount per serving (dose), and other ingredients, such as fillers, binders, and flavors. Herbal supplement manufacturers are responsible for ensuring that the claims they make about their products are not false or misleading and that they are backed up by adequate evidence.
