Another benefit of eating natto is the fact that it contains high levels of vitamin C. You’ve likely heard about all the health benefits of vitamin C from a young age. Many multivitamin supplements for kids contain high levels of vitamin C due to all the advantageous properties that it holds. The high levels of vitamin C in natto can do quite a few things for your health.
First of all, it will give your immune system a nice boost ensuring that you don’t get sick. It also protects you from free radicals which can cause neurodegenerative diseases and even cancer. The amount of vitamin C found in a single serving of natto is enough to cover a fifth of your daily requirements. That means that five servings of natto would cover you fully.
