Can Too Many Multivitamins Be Dangerous?

by Institute for Vibrant Living

While Mae West famously joked, “Too much of a good thing can be wonderful!”, when it comes to multivitamins a slightly more responsible attitude should be adopted. Two new studies into multivitamin dangers have shown why the National Institutes of Health and Office of Dietary Supplements publish carefully researched Recommended Dietary Allowances (RDA) for most dietary supplements.

Dangers of Multivitamin Excess

We all know the health problems caused by deficiencies of calcium, iron and vitamins, but in some instances too high doses can be equally unhealthy. A study in Iowa found that older women taking iron supplements actually had a slightly higher risk of dying than those who did not. This is because post-menopausal women no longer need iron supplements to offset the loss in monthly menstruation. Excess iron can cause a build-up of oxidants, the opposite of healthy antioxidants found in fruit and vegetables. The tragedy of this study result is that the women were doing everything they could to stay fit and healthy. They simply did not heed the recommended dosage.

Just like medications, while one aspirin may help reduce the risk of heart disease, 100 aspirins will kill you. When it comes to multivitamin dangers, the message is exactly the same. Read the label and take the recommended dose – no more and no less.

Another study found that men who took excessive amounts of vitamin E had a 17% higher risk of developing prostate cancer. Once again, the recommended international units (IU) of vitamin E supplements are just 22 IU per day. The participants had been taking over 400 IU per day for several years.

Although the results of both these studies are isolated and need deeper investigation, they still sound a wise note of caution about taking supplements responsibly in order to avoid multivitamin dangers.

How to Avoid Multivitamin Dangers

If you are taking a multivitamin supplement, check the label on the back for the RDA or International Units (IU) of each ingredient. In most cases you will find that the supplement provides a large proportion of your daily needs, with the balance being made up from a healthy balanced diet. Healthy people do not generally need more of each vitamin and mineral contained than that contained in a daily multivitamin.

It’s worth paying out a little more for quality multivitamins from a reputable company that specializes in health supplements. Many over-the-counter multivitamins skimp or omit some essential vitamins in order to cut costs, but this is false economy. Taking a multivitamin that is poorly balanced or lacking in certain essentials elements deceives you into thinking that you are getting your daily needs. To avoid multivitamin dangers, choose quality over price, so that you don’t need to top up with additional supplements and make sure you are staying within recommended guidelines.
