Micronutrients & recovery
Consumption of prebiotic non-digestible oligosaccharides (NDOs) such as inulin, FOS, and GOS improves calcium absorption and bone mineral density, particularly in adolescents and postmenopausal women, through mechanisms involving gut microbiota fermentation, short-chain fatty acid production, and reduced intestinal pH.
To support bone health, incorporate prebiotic fibers like inulin, FOS, or GOS into your diet. These are found in foods like chicory root, garlic, onions, and bananas, or taken as supplements. Research suggests they help your body absorb more calcium, which is beneficial for bone density, especially if you are a teenager or postmenopausal. Start with small amounts to avoid digestive discomfort.
These novel dietary fibers have been shown to increase calcium absorption in the lower intestines of both preclinical and human models... Current prebiotic mechanisms for improved mineral absorption and skeletal health include alterations in gut microbiota composition, production of short-chain fatty acids, altered intestinal pH, biomarker modification, and immune system regulation.
Why this rating
The paper reviews both robust animal data and emerging human clinical trials, noting a gap in large-scale human studies but affirming the biological plausibility and consistent directional effects.
