Also citing several pre-screening tests don’t prevent diseases or deaths. Stating that doctors only do them to pad their wallets using the patient as an ATM. Supplementing selenium every day reduces risks of liver cancer by 70%. Selenium helps absorption of vitamin C in our body. Please do not confuse synthetic ascorbic acid from whole natural vitamin C. Ascorbic acid actually makes you body vitamin C deficient .
