Heather's Tummy Care Tummy Fiber Organic Acacia Senegal POUCH Review
Heather's Tummy Fiber is presented as a 100% Acacia Senegal powder for the dietary management of Irritable Bowel Syndrome symptoms, sold in a 16 oz pouch. The page describes it as a medical food and states it is certified organic, USDA organic, CRC kosher, gluten free, and low FODMAP, with no additives, fillers, sugar, salt, artificial sweeteners, citric acid, oxalates, or yeast. It is described as 100% soluble fiber with no insoluble fiber, a slowly fermenting prebiotic that increases good gut flora, and tasteless, non-thickening and grit-free. The page claims it is designed to relieve both IBS diarrhea and constipation by regulating bowel motility, and to help reduce abdominal pain, spasms, cramps, bloating and gas. The product is described as not a drug, not a laxative, and not an anti-diarrheal, and as safe for daily lifelong use and for children, with no GI irritants or stimulants. Directions say to start with a half level teaspoon twice daily, stir into moist foods or dissolve in room temperature liquid, and increase gradually every three to five days until symptoms stabilize. Typical final doses are listed as 4 to 18 grams per day for adults, with a maximum of 30 grams. The nutrition panel lists a serving size of 2.5 grams, 180 servings per container, and 10 calories and 2 grams of soluble fiber per serving. Cooking and baking uses are described, with one tablespoon per cup of liquid or flour. Cautions advise use under physician supervision, keeping out of reach of children, telling a doctor if pregnant or nursing, consulting a physician if under 12, and using within 12 months of opening. The page also addresses water quantity and choking risk, stating that the powder does not thicken in liquids and can be added to food or drink in advance. It notes that constipation may take weeks or months to resolve, and that the fiber must be taken consistently throughout the day to work.
