Fructooligosaccharides

Fructooligosaccharides (Oligolevulose) are a class of orally active dietary fibers and prebiotics. Fructooligosaccharides exist in foods such as breast milk, wheat, honey, onions, garlic and bananas. Fructooligosaccharides resist hydrolysis by the body's digestive enzymes and stimulate the growth of beneficial intestinal bacteria through colonic fermentation. Fructooligosaccharides significantly prevent bone loss in the femur and lumbar spine^[1][2]. In Vitro: Fructooligosaccharides resist hydrolysis by digestive enzymes in the body and are fermented in the colon to stimulate the growth of beneficial intestinal bacteria^[2]. In Vivo: Fructooligosaccharides (5-10%) prevent bone loss and promote bone mineralization in rats under calcium-supplemented diets^[2].
Fructooligosaccharides (5 g/kg diet; administered orally via diet) enhance mineral absorption capacity in rats: when used alone, they only promote magnesium absorption, while when used in combination with cellulose, they promote the absorption of calcium, magnesium, zinc and iron^[2].
