Most people think it's okay to take whatever they want, but the truth is that there is a limit to how much you can safely consume. According to experts, vitamin D, calcium, and folic acid are three nutrients that you can take in excess, especially through supplements. However, just because supplements are safe in moderation doesn't mean more is better. Combining several supplements or taking higher than recommended doses may increase the risk of them causing harm.
Even if a supplement is generally considered safe, it may not be safe for you. When it comes to supplements and risks, there is no one-size-fits-all solution. When you take prescription or over-the-counter medications, you should also consider if there are any dangers when mixing medications and dietary supplements. Dietary supplements can sometimes interact with each other, as well as over-the-counter (OTC) and prescription drugs.
Unlike drugs, the U. S. Food & Drug Administration (FDA) is not authorized to review the safety and efficacy of dietary supplements prior to marketing. It is up to manufacturers to ensure that their products contain no contaminants or impurities, are properly labeled and contain what they claim.
The regulation of dietary supplements is much less stringent than for prescription or over-the-counter drugs. The Dietary Supplements Health and Education Act of 1994 notes that in 1994 there were about 4,000 dietary supplements marketed in the United States, but the industry has grown and 50,000 to 80,000 products are now available. Some consumers may believe that a so-called “natural” product, such as an herbal supplement or fish oil, cannot harm them. However, people with an inherited condition called hemochromatosis should be careful with iron supplements, as hemochromatosis causes toxic levels of iron to build up in their bodies.
While many people can meet their nutrient needs through their diet, others can benefit from supplements. Vitamin D supplements are popular because it's difficult (if not impossible for some) to get enough from food. Vitamin C supplements may also interact with cancer treatments, such as chemotherapy and radiation therapy. If you are planning surgery, keep in mind that some dietary supplements may interact in a harmful way with medications you must take before, after, or during surgery.
The most recent consensus statement from the American Geriatric Society specifically suggests that people 65 and older can help reduce the risk of fractures and falls by supplementing their diet with at least 1000 IU of vitamin D per day, in addition to taking calcium supplements and eating foods rich in vitamin D. If used correctly, some supplements may improve your health, but others may be ineffective or even harmful. You should always talk to your doctor about the supplements you are taking and the dosage you are taking before adding them to your regimen. In conclusion, while many people can meet their nutrient needs through their diet alone, others may benefit from taking dietary supplements in moderation.
However, it is important to remember that dietary supplement regulation is much less stringent than for prescription or over-the-counter drugs and that some supplements may interact with medications or cause harm if taken in excess.
