Vitamin E is a fat-soluble vitamin, an essential nutrient for human body and one of the indispensable bioactive substances, which plays an important role in ensuring human health and preventing diseases. It has been scientifically proved that vitamin E plays an important role in anti-oxidation and anti-aging. Like vitamin C and trace element selenium, it is a powerful antioxidant. You can take the natural vitamin e of Yangshengtang. But you can't take it with beginning of winter, because beginning of winter is a drug with high content of vitamin C, and VC and VE complement each other, which can reduce it. So I think it's better to take them separately. Vitamin E in Yangshengtang is a health food made of natural vitamin E, safflower seed oil, perilla oil, gelatin and glycerin, which has the functions of beautifying (removing chloasma) and delaying aging. So no side effects have been found so far.
