Fiber supplements can interfere with medication absorption — take medications at least 1-2 hours before or after fiber supplementation. This applies particularly to thyroid medications, diabetes medications, and lipid-lowering drugs. Fiber has a low direct drug interaction risk but affects GI transit rate.

Fiber supplements are well tolerated long-term and represent a normal dietary component. Gas and bloating during initial use (first 1-2 weeks) are common as gut microbiota adjusts to increased fiber. Gradually increasing dose minimizes these effects. No safety concerns with long-term fiber supplementation.

Gas, bloating, and GI adjustment are common during the first 1-2 weeks of fiber supplementation. Starting with a lower dose (2-3 capsules/day) and increasing gradually reduces these effects. Adequate hydration is essential — fiber without sufficient water can cause constipation.

Fiber supplements pair well with probiotics for comprehensive gut health support — fiber acts as a prebiotic substrate for beneficial bacteria. Compatible with most daily vitamins and minerals. Space from medications by at least 1-2 hours to avoid interference with medication absorption.

Take 5 capsules daily as directed. Drink plenty of water throughout the day — fiber requires adequate hydration to function properly. Start with 2-3 capsules and increase gradually over 1-2 weeks to minimize GI adjustment symptoms. Take medications 1-2 hours apart from fiber supplements.

Digestive regularity benefits from fiber supplementation are typically noticed within the first week of consistent use. Colon health and microbiome benefits from sustained fiber intake develop over 4-8 weeks. True Dispersion Technology supports even GI tract contact for consistent benefit.
