Question

Quizplus · Accepted Answer

Vitamin E acts as an antioxidant and protects other compounds, such as vitamin A and polyunsaturated fatty acids, from oxidation. Option A is incorrect as there is no scientific evidence to support the claim that vitamin E is an anti-sterility agent in humans. Option C is partially correct as vitamin E has multiple functions in the body, but it is not necessarily needed as a dietary supplement for everyone. Option D is not entirely accurate as while vitamin E may have some anti-aging effects, it is not a direct cause of slowing down the aging process. Option E is incorrect as vitamin K, not vitamin E, is responsible for activating blood clotting factors.
