Vitamin C is prone to oxidation. When it encounters copper ions, the oxidation rate can be more than 1000 times faster than normal. Animal livers happen to be rich in copper. When Vitamin C meets the copper in animal liver, it rapidly oxidizes and loses its biological function. Avoid alcohol when taking Vitamin A
The main function of Vitamin A is to convert retinol to retinal. However, ethanol in the metabolic process inhibits the formation of retinal, which severely affects the visual cycle and sperm production in men. Avoid foods containing boron when taking Vitamin B6
Boron in food combines with Vitamin B6 to form chelates after encountering digestive fluids, which affects the absorption and utilization of Vitamin B6. Therefore, when taking Vitamin B6, avoid foods high in boron, such as pumpkin, carrots, eggplant (also known as luosu, aigua, diao caizi), etc. Avoid high-fat and high-fiber foods when taking Vitamin B2
