Side Effects of Men's One-a-Day Vitamins

One-A-Day Vitamins Men's Health Formula are multivitamins available over-the-counter in a pharmacy or drugstore. According to the manufacturer, this multivitamin has been formulated for men and contains nutrients designed to keep the heart healthy, support a healthy blood pressure, support immunity and maintain physical energy. Men's One-A-Day contains vitamins A, C, D, E, K and the group of B vitamins. The vitamin also has calcium, magnesium, selenium and zinc. Like other medications and supplements, Men's One-A-Day may cause side effects.

Increased Risk of Bleeding

Men's One-A-Day vitamins contain 22.5 IU of vitamin E. Vitamin E may increase the risk of bleeding. Patients who take blood thinners, such as warfarin, aspirin and clopidrogel, are at a higher risk of bleeding and should avoid taking vitamin E. Always inform your physician of all prescription and over-the-counter medications to avoid adverse reactions.

Flushing

Niacin, or vitamin B-3, may cause flushing, which is described as redness and burning in the face and chest, in high doses. One-A-Day Men's Health Formula contains 16 mg of niacin, which is about 80 percent of the daily value. This amount should not cause flushing, but if you develop this side effect, you may take aspirin about 30 minutes before taking the vitamin, explains the University of Maryland Medical Center. If you develop itchiness or a rash, discontinue the medication and contact your physician.

Increased Triglycerides

One-A-Day Men's Health Formula contains 3,500 IU of vitamin A, which can increase triglycerides. Triglycerides are the fat molecules found in food and stored in the body. A high triglyceride level can increase the risk of death from heart disease. Keep all doctor appointments to ensure proper monitoring of triglycerides.

Diuretic Effect

One-A-Day Men's multivitamins contains 60 mg of vitamin C. Vitamin C has a diuretic effect on the body, meaning that is promotes the release of fluids primarily through the urine. This has the potential to cause dehydration. Take the vitamin with a full glass of water and drink plenty of fluids.

Nausea, Vomiting, Constipation

Calcium, which is found in these vitamins, may cause upset stomach and nausea. Taking with a meal may reduce gastrointestinal side effects. It may also cause constipation; consume an adequate amount of fiber to avoid this adverse effect. High doses are vitamin B-1, vitamin D, folic acid, vitamin C and vitamin A may cause upset stomach, nausea and vomiting. High doses of vitamin D may lead to excessive thirst and a metallic taste in the mouth. Always ask your physician or pharmacist if any multivitamin is safe for you and never take more than the recommended amount to avoid overdoses and undesired reactions.
