What the Science Says
Arrowroot powder is a fine, white starch extracted from the tropical plant Maranta arundinacea. It has a long history of traditional use as a gentle food for soothing upset stomachs, managing diarrhea, and supporting recovery from digestive illness — similar to how plain rice or toast is used. It is also used as a gluten-free thickening agent in cooking. Any digestive benefits are based largely on traditional use and its bland, easily digestible starch content, not on clinical trials.
What It Doesn't Do
Not proven to treat any medical condition. No clinical evidence it cures IBS, heals the gut lining, or acts as a meaningful prebiotic. Won't help you lose weight. Not a proven anti-inflammatory supplement. Don't confuse 'traditional use' with 'clinically proven.'

Absorption & Bioavailability
Unknown — no clinical pharmacokinetic data available. As a starch, it is generally considered easily digestible.
Red Flags to Watch For
- No clinical trials found to support specific health claims — any medical-sounding benefits are based on tradition, not evidence
- Often marketed as a 'gut healer' or prebiotic without supporting research
- High starch content means it contributes calories and carbohydrates — relevant for people managing blood sugar
- Products with 1,000+ registered supplement formulations but only 1 indexed clinical trial suggests heavy marketing outpaces the science
