Although vitamin E supplements are believed to protect us from cancer, a study has proven that they are not safe and can even increase the risk of prostate cancer. Which means they are not as effective as people think. Instead of taking this supplement, we can eat spinach, avocadoes, and nuts to have natural sources of vitamin E.
4. Mass gainers
Mass gainers are totally unnecessary if people follow a healthy diet. Also, these types of supplements are full of sugar, which may result in people gaining too much extra weight, increasing the chance of diabetes and high blood pressure.
