Dose or use
5–10 g mixed in a full glass of water, 1–3x daily with meals.
Time to results
Typically 1–3 weeks
Key study
Randomized Controlled Trial (2024, PMID 37389917): Agave tequilana Fructans Versus Psyllium plantago for Functional Constipation — a double-blind trial in which psyllium supplementation increased complete spontaneous bowel movements in adults with functional constipation.
