Vitamin A may lower chronic inflammation in women

Vitamin A can help regulate the immune system by helping reduce chronic inflammation. Those who are obese also have chronic low-level inflammation.

In this study, doctors gave a placebo or 25,000 IU of vitamin A per day to 75 obese and non-obese women. After four months, compared to placebo, vitamin A significantly reduced levels of two inflammatory proteins linked to type 2 diabetes and hardening of the arteries. Both inflammatory proteins affect the immune function, and lowering their levels could decrease chances of women developing these chronic diseases, researchers said. Because vitamin A can regulate the immune system, doctors say more study may also reveal a link to autoimmunity in women.
