Calcium and PHGG are generally complementary — many people take them together. PHGG (5 g/day) can be combined with calcium supplementation to improve GI tolerance and potentially enhance colonic calcium absorption. Particularly useful for elderly individuals prone to calcium-induced constipation.
PHGG may modestly improve calcium absorption through colonic fermentation pathways, similar to but less potent than inulin. The fiber also may reduce calcium-induced constipation (a common side effect of calcium carbonate) by improving bowel motility.
Partially hydrolyzed guar gum (PHGG) acts as a prebiotic fiber, increasing colonic SCFA production (particularly butyrate and propionate). Like other soluble fibers, PHGG fermentation lowers colonic pH, enhancing passive calcium absorption in the large intestine. Additionally, PHGG slows gastric emptying, potentially improving calcium-food contact time in the small intestine.
What to do: PHGG (5 g/day) can be combined with calcium supplementation to improve GI tolerance and potentially enhance colonic calcium absorption. Particularly useful for elderly individuals prone to calcium-induced constipation.
