I have had environmental, chemical, and food sensitivities for a long time. I have horrible adrenal exhaustion as well as ptsd which both greatly contribute to my horrible digestion as well as the daily struggle. I know my way around every different diet as I've tried them all in an attempt to thrive. Pretty strict Paleo works well for me, which took me forever to find out. I focus on gut nourishing foods. I take several different supplements but the 3 that have the greatest impact are: Perque brand Potent C Guard, and lots of it(high quality vitamin c great for all sensitivities), betaine hcl(stomach acid, stress greatly reduces your bodies production of this and it is so vital for absorbtion of nutrients), Digest Gold digestive enzymes(assists greatly with breaking down the food for greater absorbtion, also frees up energy that is normally used for digestion. They all help to "prop" me up for most of the day and night.
