supplements

But it's not just vitamin D. You can get toxicity effects from numerous vitamins and minerals taken in excess including vitamin A, B-vitamins, and calcium. Too much vitamin A can result in hair loss, bone pain and damage, skin problems, and liver damage. Over-consuming vitamin B6 can lead to irreversible nerve damage, while too much calcium can lead to the development of calcium deposits in the kidneys and other organs. The bottom line: Popping a multivitamin or supplement won’t correct an unhealthy diet and you should only be taking one if you verified that your body needs it. First, see your physician and/or registered dietitian to see if you're deficient. My philosophy is food first: If you're eating a well-balanced diet you should be in the clear. Consult an R.D., who can analyze your daily meal plan to see how much you’re getting from food, help you make any changes to get the necessary nutrients from your diet, and if necessary recommend the proper dosage from supplementation.Toby Amidor is a registered dietician and adjunct professor at Teachers College, Columbia University in New York City, and author ofThe Greek Yogurt Kitchen.
