Which of the following is listed among RA key supplements?

• A. Selenium
• B. Vitamin A
• C. Zinc
• D. Manganese

Answer: (A)

The main idea here is why certain nutrients are highlighted for rheumatoid arthritis due to their specific actions in inflammation and antioxidant defense. Selenium stands out because it is a key component of glutathione peroxidase, an enzyme that helps neutralize hydrogen peroxide and other reactive oxygen species. By supporting this antioxidant system, selenium can help limit oxidative stress that often accompanies RA. It also has roles in modulating immune function, which can influence inflammatory processes in the joints. For these reasons, selenium is commonly listed as a key supplement in RA management.

While the other nutrients are important for overall health, they aren’t typically highlighted as primary RA supplements in standard guidance. Vitamin A, though essential, isn’t emphasized for RA and excess intake can be problematic. Zinc supports immune function more broadly but isn’t usually a listed RA key supplement. Manganese also serves enzyme roles but isn’t singled out as a primary RA supplement.
