25 Jul 2025 • Higher dietary magnesium may help protect against cataracts, according to a large analysis of 8,185 adults aged ≥30 years.

Key Findings:

• Researchers found a 13.4% prevalence of cataracts, but individuals with the highest magnesium intake had a 22% lower odds of undergoing cataract surgery compared to those with the lowest intake (OR 0.78).
• Even when assessed as a continuous variable, magnesium intake remained inversely associated with cataract risk (OR 0.78).

These findings suggest a potential protective role for magnesium.
