The Power of Brazil Nuts: Nature’s Richest Source of Selenium
Just two Brazil nuts a day supply all the selenium your body needs to keep your thyroid, immune system, and brain working at their best, protect your cells from damage, and boost heart health. Selenium is essential not only for thyroid hormone production, but also for defending the body with antioxidants, supporting immunity, and helping the brain stay sharp. It contributes to DNA formation, reduces inflammation, and even supports a healthy heart.
**Key benefits of selenium include:**
- Thyroid health: Needed to produce and balance thyroid hormones, which control metabolism.
- Antioxidant protection: Helps neutralize cell-damaging free radicals, lowering risks of chronic illness.
- Immune support: Strengthens the immune system to fight infection.
- Brain function: Supports memory, coordination, and cognitive health; may help protect against neurodegenerative disease.
- Heart health: Reduces oxidative stress and inflammation for cardiovascular benefits.
- DNA and fertility: Aids DNA formation and supports reproductive health.
*Note*: Eating more than 4-5 Brazil nuts in a day can exceed the recommended upper limit of selenium intake and may cause toxicity if done regularly. If you’re taking selenium supplements, consider switching to Brazil nuts but don’t combine both.
