Fermentable oligosaccharides, disaccharides, monosaccharides, and polysaccharides (FODMAPs) are a category of carbohydrates which can be poorly absorbed in some people and will contribute to digestive signs.

It claims to cut back GI signs in addition to irritation, cravings, complications, nervousness, fatigue, mind fog, joint ache, and pores and skin irritation.
