Most people think it's okay to take as much as they want, says Rosenbloom. I know people who take 10, 000 mg a day. However, the tolerable upper limit is 2, 000 mg per day. People at risk for kidney stones may increase that risk; people may also have diarrhea.
The Institute of Medicine has determined the maximum limits for 24 nutrients. This table is for adults 19 years of age or older. It does not apply to pregnant or breastfeeding women, because they have different nutritional requirements. Once you know what you need the most, the next logical step is to add supplements of those vitamins to your daily routine.
Supplements have labels that indicate how much is a dose of the recommended diet needed, so that's where you can fill the gap, Dr. Bailey says, adding that aiming for 100 percent is a good barometer to follow. The problem arises when you don't track the percentage. So what is the first physical indicator that you are getting too much of something? Dr.
Bailey says that every nutrient has different red flags, but the Office of Dietary Supplements, which is connected to the National Institute of Health, has some pretty amazing fact sheets that lay everything out in great detail. But just because supplements are safe in moderation doesn't mean that more is better. Combining multiple supplements or taking higher doses than recommended can increase the risk that they will actually cause harm, says Kitchin. In addition, because the industry is not well regulated, there is no real guarantee that the ingredients and dosage on the label will be accurate.
Vitamin D promotes calcium absorption in the body, and getting enough is critical to health and well-being, offering the promise of protecting bones and preventing bone diseases such as osteoporosis. Supplemental vitamin D is popular because it is difficult (if not impossible) to get enough from food. In addition, as noted by the Centers for Disease Control and Prevention (CDC), our bodies produce vitamin D when bare skin is exposed to sunlight, but increased time spent indoors and widespread use of sunscreen have minimized the amount of vitamin D that many of us get from sun exposure. Calcium is essential for strong bones and a healthy heart, but too much is not good.
In fact, excess calcium, which the NIH describes as more than 2,500 mg per day for adults ages 19 to 50, and more than 2,000 mg per day for people age 51 and older, can cause problems. According to the Cleveland Clinic, “researchers believe that without adequate vitamin D to help absorb it, extra calcium is deposited in the arteries rather than in the bones. The National Institutes of Health (NIH) recommends 1,000 mg of calcium daily for women ages 19 to 50 and 1,200 mg daily for women age 51 and older. The recommendation for men aged 19 to 70 years is 1000 mg per day and 1200 mg daily for men age 71 and older.
UU. (USDA), 6 ounces of low-fat plain yogurt contains about 311 mg of calcium, a little less than a third of the daily recommendations. Other good sources of calcium include tofu, skim milk, cheese, fortified cereals, and juices. A surprising study published in the journal JAMA Internal Medicine, which examined data from nearly 40,000 women over 19 years, found that, on average, women who took supplements had a higher risk of dying compared to women who did not take supplements.
Multivitamins also did little or nothing to protect against common cancers, cardiovascular disease, or death. Consumers are bombarded with health information that tells them that taking high doses of certain vitamins can benefit their health in many ways. However, taking too many nutrients can be dangerous. The FDA sets guidelines on how much of each vitamin and mineral a person should consume per day.
Health experts refer to this as DV. Your doctor and pharmacist can also tell you if a supplement interacts poorly with any medication you are taking, which can cause health problems. Supplements can also interact with each other, says Kitchin, or with medications you're already taking. Jenkins agrees that, when taken in moderation, most vitamin and mineral supplements do no harm.
Thomas, EdD, RD, Scientific Consultant, Office of Dietary Supplements, National Institutes of Health, Bethesda, MD. Supplements can be used to get the recommended daily allowance of vitamins and minerals you need for a healthy body. While most people can achieve these values through food alone, people on restrictive diets or with certain health conditions may need to take dietary supplements. Although many people safely consume vitamin supplements on a daily basis, it is possible to take too high a dose, which can lead to adverse side effects.
Many of the terms you see on labels or supplement websites can help you understand how much vitamin or mineral you should take. If a person is concerned about taking too many supplements, they should seek guidance from a healthcare professional. People should always contact a doctor before taking new supplements or multivitamins, as excessive consumption of certain nutrients can have adverse effects. When it comes to supplements, there is so much enthusiasm about their potential benefits that it can be difficult to separate fact from fiction.
On the one hand, dietary supplements can sometimes interact with each other, as well as with over-the-counter (OTC) and prescription drugs. Taking too many dietary supplements or consuming a specific vitamin or mineral in excessive amounts could cause serious side effects. Millstine, noting that research shows that calcium is better absorbed through food than through. .
