What the Science Says
Peach (Prunus persica) is a fruit whose gum, flesh, and proteins appear in supplement and food allergy research. Peach gum contains an arabinogalactan (PG-2) that, in early animal studies, may support gut health by feeding beneficial bacteria and activating serotonin signaling pathways linked to constipation relief. Peach is also studied as a source of the allergen Pru p 3, a lipid transfer protein, with some research exploring immunotherapy to help people with peach allergies tolerate the fruit better.
What It Doesn't Do
Not proven to treat constipation in humans — animal data only so far. No evidence it boosts immunity, burns fat, or detoxifies the body. Peach extract is not a proven allergy cure. Don't confuse food allergy immunotherapy research with general supplement benefits.
Evidence-Based Benefits
Peach gum arabinogalactan may support gut bacteria and ease constipation in aging animal models.

Absorption & Bioavailability
Unknown — no human pharmacokinetic data provided in the available studies
Red Flags to Watch For
- Peach is a common food allergen (Pru p 3/LTP allergy); people with known peach or stone fruit allergy should avoid peach-derived supplements
- Most promising findings (gut health, constipation relief) come from animal models, not human clinical trials
- Peach gum supplements are largely unregulated; purity and dosing are not standardized
- Over 1,000 supplement products list peach as an ingredient, but clinical evidence for any specific health benefit is very limited
