Manganese is found in very high amounts in most whole, plant-based foods. Meat and animal products contain little to no manganese, with a few exceptions. Legumes, grains, nuts, and seeds, typically provide enough manganese (3 mg) in a 100-200 gram serving. If you eat these foods regularly, you are almost certainly getting more than enough Mn.
