Doctors and the media recommend taking a wide variety of supplements to avoid a majority of illnesses. However, if your head is spinning out of control with what supplements you should be taking, here are some vitamins and minerals you can safely avoid.

Calcium – Although calcium is crucial for healthy, strong bones, research suggests that calcium taken in supplement form, cannot be easily absorbed into bones. Instead, calcium taken as a supplement will calcify arteries and soft tissue which can increase the risk of heart disease. Add calcium to your daily diet by drinking a glass or two of milk for the best results.

Vitamin E – Vitamin E is said to reduce cardiovascular disease, Alzheimer’s, cataracts, and cancer, but the vitamin can also increase risks of certain cancers. Therefore, opt against consuming this supplement and use it on your skin instead.

Iodine – Iodine is used to improve the health of your thyroid gland, which is key to producing the right amount of hormones. Too little iodine can cause an underactive thyroid. To check if you need this mineral, ask your doctor to perform a thyroid test.

Iron – Iron helps to form hemoglobin, which delivers oxygen from the blood to the lungs and the body. Opt only to take this supplement if you are tested as being deficient as excessive use can cause liver, pancreas and heart damage.
