Essential Nutrient Charts

The following charts lay out the sources and benefits of all of the essential vitamins, minerals, fatty acids, and amino acids. We’ve included a range of sources for each essential nutrient; it is important to keep in mind that some sources are better than others. Foods that are organic and non-GMO are going to be better sources than conventional produce. In addition, we’ve included sources like grains and soy in our list for the sake of full transparency. However, we find that foods like meat, fats, and vegetables are better (and more bioavailable) sources of these nutrients.

Finally, we need to note that these benefits haven’t all been approved by the FDA and we’re including them simply as an educational tool. For more information about the bioavailability of these nutrients in food, read our post on nutrient density.
