I only know a small bit about what there is to know about nutrition. Here is a complete (I think) list of all the vitamins and minerals. https://www.health.harvard.edu/staying-healthy/listing_of_vitamins The Nutrients not included on the list are: Carbohydrates, Protein, Fat, Water.   My question is, What would happen if you consumed the 100+% of the RDA on all of them? How would you feel? Is it possible? Is it that hard? Also, the intake of the nutrients does not have to be restricted to the RDA. What I really mean is what you somehow consumed of all the things the body needs to the point where the body starts giving less and less benefits for each Mg of said vitamin,mineral or nutrient consumed.
