Ultra GI Cleanse typically produces results within 6-12 hours. When taken at bedtime, most people experience comfortable bowel movements the following morning. Start with 2 capsules to assess your individual response, then adjust as needed.

Ultra GI Cleanse is designed for occasional use or short-term cleansing programs (7-14 days), not daily long-term use without healthcare supervision. For ongoing digestive health, focus on increasing dietary fiber from whole foods, drinking plenty of water, exercising regularly, and managing stress.

Fiber requires adequate water to work effectively. Without sufficient hydration (at least 8-10 glasses daily), fiber can actually cause discomfort, bloating, or constipation rather than relieving it. Water helps fiber swell and move smoothly through your digestive tract, promoting comfortable elimination.

Take Ultra GI Cleanse at least 2 hours before or after medications or other supplements. Fiber and cleansing herbs can interfere with the absorption of medications, vitamins, and minerals. If you're on prescription medications, especially for diabetes, heart conditions, or thyroid, consult your healthcare provider before use.
