Our study examined the effects of selenium in treating mild-to-moderate Graves' orbitopathy (GO) over five years. We followed 74 patients who took selenium or a placebo for six months, tracking their symptoms and quality of life.
Initially, selenium showed promise by reducing symptoms like blurred vision, with significant improvements over six months. However, when we looked at long-term outcomes after five years, both groups had similar results, indicating that while selenium may help in the short term, it doesn't contribute to lasting changes.

Immune system boosted
Immunity Defender Selenium is essential for the body's immune system. It aids in the response to pathogens and presents several benefits, including protecting against chemical threats and improving the metabolism of fats, proteins, and carbohydrates. A deficiency can lead to poor clarity of thought, weakened immunity, and blurred vision, while excess selenium may cause skin peeling and hair loss. I've been taking Life Extension's 200 mcg selenium with vitamin E, which I find beneficial.
