What Foods Can Help Increase My Vitamin B12 Levels?

8. Clams & Shellfish: The B12 Superstars

Looking for the single best natural source of Vitamin B12? Cooked clams are hard to beat, delivering an astounding 3,500% of your daily recommended value in just a 3-ounce serving. But clams aren’t the only B12-rich shellfish worth adding to your meals, oysters and mussels are also excellent sources. As an added bonus, all these shellfish provide iron, zinc, and heart-healthy omega-3 fatty acids, while offering lean, low-fat protein.

To get the most from these seafood treasures, use light cooking methods like steaming or baking, which preserve nutrients without adding excessive salt, butter, or oil. And of course, anyone with a shellfish allergy should avoid these foods entirely.
