9. Probiotics
A probiotic is a supplement that delivers live bacterias that are great for your gut. Basically it's all the good stuff you get from eating fermented foods, but in a pill form. Even if you take a probiotic supplement, still strive to eat probiotic-rich foods.

It's important to choose a high-quality probiotic, like this one here by MegaFood. In fact, their MegaFlora probiotic line is the first in the industry to add the 'Non-GMO Project Verified' seal to their probiotic product!
