Energy, focus, and health start with B12: Discover easy ways to boost your intake.
Red meat is rich in vitamin B12. A 3-ounce serving of beef liver provides nearly 3,000% of the daily recommended value, while lean cuts of beef, such as sirloin or tenderloin, offer about 55–60%. Though red meat is rich in iron and protein, it can also be high in saturated fat. Choosing lean, trimmed cuts and enjoying them in moderation allows you to benefit from B12 without excess fat.
