A couple of studies conducted on these multivitamin supplements states that these pills can increase the risk of cancer. One study suggests that the risk of cancer called malignant melanoma (known as the deadliest form of cancer) can increase by four folds by taking these multivitamin pills. Another study states that the multivitamin pills increase the risk of breast cancer by twenty percent.
Another study conducted by University College London stated that multivitamin pills boost the fertility rate by sixty percent. Dr. Rina Agrawal says that "The implications of this study are far reaching as they suggest that prenatal micronutrient supplementation in women undergoing ovulation induction improve pregnancy rates."
Vitamins are the most essential nutrients required by our body for its normal functioning. And it will be even more better if you get these nutrients through your food in the natural form. A diet that includes fresh fruits, vegetables, whole grains, bread, cereals and milk is a natural form of multivitamin supplement for one's body.
