While a balanced diet should be your primary source of vitamins, many people take multivitamins or vitamin supplements to boost their intake. Depending on your circumstances, it may be necessary to eat fortified foods or take a vitamin supplement as well. While the benefits of vitamin supplements can be numerous, they should never be the only source of your vitamins. For instance, vitamin D deficiency is associated with heart disease and cancer.
Antioxidant vitamins are particularly popular among consumers. There are a variety of studies examining the effects of vitamin supplements. One recent study by Johns Hopkins Medicine looked at 277 clinical trials and 24 interventions. Although it showed a positive correlation between vitamin D and cardiovascular disease risk, researchers noted that there is no cause and effect between the two. In addition, antioxidant vitamin supplements do not replace other preventive measures, such as lowering blood pressure and stopping smoking. Researchers are still trying to prove the benefits of these supplements, but they don’t seem to be very promising.
There are also several studies that show that vitamin supplements can reduce the risk of non-communicable diseases. For instance, supplementation can lower your risk of dying if you are not eating enough of certain foods rich in vitamins and nutrients. Studies have also shown that supplementation is effective for people with low levels of micronutrients. Dietary changes may also make it necessary to take a supplement. A well-balanced diet is the key to improving your health.
Taking vitamin supplements can be beneficial for people who are deficient in certain vitamins or have a low intake of essential nutrients. But it’s important to remember that vitamin supplements are only additives to a healthy diet. You should also ask your doctor about them before taking them. If you’re unsure whether vitamin supplements are right for you, consult your physician. In some cases, vitamin supplements may even increase your risk of chronic diseases.
One recent study published in JAMA Internal Medicine examined nearly 40,000 women over a period of 19 years. They concluded that multivitamins do not prevent cardiovascular disease, common cancers, or even death. However, recent studies show that taking vitamin supplements can improve your health. A recent study published in Nutrients suggests that frequent use of multivitamins prevents micronutrient deficiencies. However, excessive intake of a vitamin may have negative effects.
Research on the benefits of vitamin supplements is mixed, with conflicting results. Several trials, however, have shown that taking vitamin supplements may increase your risk of cancer. However, this is not true for all vitamins. A study in Sweden found that long-term use of retinol, b-carotene, and lutein may increase your risk of lung cancer. Another study in men found a significant association between high-dose vitamin E and increased risk of prostate cancer.
The benefits of vitamin supplementation are numerous. Studies have shown that vitamin supplements can lower the risk of non-communicable diseases, including cancer. They may be particularly helpful in populations with low micronutrient intake, such as people on the ketogenic, Paleolithic, or vegetarian diets. A supplementation program may be necessary for some people with chronic illnesses, too, such as those with osteoporosis.
Taking vitamin supplements should be an occasional treat and not a daily requirement. For most people, vitamin supplements may only be beneficial if you eat plenty of fruits and vegetables. In the long run, it is best to consume a variety of foods in moderation. A dietary supplement is a great idea only if the recommended daily allowance isn’t met. There are dietary guidelines for most nutrients, published by the Institute of Medicine. However, it’s important to follow these guidelines and consult your physician before starting a vitamin program.
Some people are interested in taking vitamin supplements that contain antioxidants. Some large observational studies have shown that antioxidant vitamins can reduce the risk of major cardiovascular events. But these studies do not show cause-and-effect relationships, and they do not mean that antioxidant vitamins will replace the need for other measures like lowering blood cholesterol and avoiding smoking. Clinical trials are underway to determine whether or not vitamin supplements will provide overall benefits, but the recent large placebo-controlled study was unable to find any such effect.
