5. Recently popular vitamin E related QA

Conclusion:When choosing vitamin E, priority should be given to natural food sources, and supplements should be selected in appropriate form and dosage based on individual circumstances. Recent studies have shown that complex antioxidants (containing vitamins C + E) are more effective than single supplements, and it is recommended to obtain a variety of nutrients through a balanced diet.
