Non-digestible oligosaccharides (NDOs) such as inulin and oligofructose increase true fractional calcium absorption in adolescents and postmenopausal women.
If you are an adolescent or postmenopausal woman, consuming 8-15 grams of inulin or oligofructose daily (e.g., in fortified orange juice) can significantly improve how much calcium your body absorbs. This is a functional food approach that may help if you struggle to meet calcium requirements through diet alone.
ModerateSupportsMEDIUM confidence
Emerging evidence has shown that certain non-digestible oligosaccharides (NDOs) can improve Ca absorption in adolescents and adults.
