    Intestinal Motility

    Healthy bowel movement frequency and regularity.

    TL;DR

    Fibre, fluid, movement and a consistent morning routine fix most sluggish transit. Magnesium is the most dependable supplemental lever when those are already in place.

    Why It Matters

    Slow transit causes constipation, bloating and discomfort, and chronically strained defecation contributes to haemorrhoids and pelvic floor problems. New-onset change in bowel habit in an adult over 45 warrants medical assessment before self-treatment.

    How to Measure

    Biomarkers

    Bowel movements per week
    Bristol stool scale
    Straining and completeness
    Fibre intake
    Fluid intake

    Optimization Protocol

    Build to 25-35 g of fibre daily from mixed sources, increasing gradually with fluid to avoid bloating. Walk daily, and use the gastrocolic reflex by allowing unhurried toilet time after breakfast with feet elevated. Magnesium citrate or oxide at 200-400 mg in the evening is the most reliable supplemental step. Escalate to an osmotic laxative under medical advice if unresolved.
