The combination of supplements does not usually interfere with their functioning and, in some cases, may even be beneficial. For instance, vitamin C helps the absorption of iron. However, just because supplements are safe in moderation does not mean that more is better. Combining several supplements or taking doses higher than recommended may increase the risk of harm, according to Kitchin.
Fortunately, there are no known harmful side effects. Dr. Airey states that “it's simply not efficient to take them together, as the body's ability to absorb vitamins will be reduced if taken together.” For example, many vitamins for older people contain more calcium and vitamins D and B12 than younger people need. Data from the National Health and Nutrition Examination Survey (NHANES) indicates that people may continue to consume supplements.
Even if none of the supplements separately exceeds the maximum limit for a given nutrient, combining several pills, such as a multivitamin and an additional vitamin D capsule, for example, can result in higher doses than recommended. Scientific research shows that taking a lot of supplements does not seem to have real health benefits and, in some situations, could be harmful. In addition to not taking all your supplements at once, it is important to know that you are taking them correctly. While fish oil supplements with omega-3 are great for heart health and ginkgo biloba can be used to help with cognitive decline, according to Dr.
Rodgers, taking too much of a good thing can be a bad thing. Rodgers warns that this is especially true in the case of supplements. The most important question consumers have about supplements is often the best practices for taking them. According to the National Institutes of Health, taking high doses of vitamin C can cause stomach cramps and diarrhea.
These vitamins, minerals, and herbal products are meant to improve your health in a number of ways and can be an effective way to fill nutritional gaps in your diet. However, some studies show no evidence that many popular supplements have real health benefits, leading many scientists to change some of their recommendations. It is important to remember that while taking multiple vitamin supplements can be beneficial in some cases, it is important to consult with your doctor before doing so. Your doctor can help you determine which vitamins and minerals you need and how much you should take each day.
Additionally, it is important to read labels carefully and follow dosage instructions closely when taking any supplement.
