Black stool can be alarming to notice. In some cases, it’s caused by harmless factors like eating dark-colored foods (blueberries, black licorice) or taking iron supplements. However, persistent black stool may also signal bleeding in the upper digestive tract and should not be ignored. Because it can range from minor to serious causes, it often brings stress and concern.
Along with seeking medical evaluation to rule out underlying issues, natural supplements may help support digestive balance and maintain healthy stool patterns. Certain nutrients can ease irritation in the digestive system and improve gut health.
Here are two evidence-based supplements that may help with black stool (when not caused by serious medical conditions).
Probiotics
Probiotics are beneficial bacteria that help balance the gut microbiome. An unhealthy gut environment may contribute to irritation, irregular bowel movements, and stool changes. Probiotics support overall digestion and may help normalize stool consistency and color.
- Mechanism of action: Restores healthy gut flora and reduces digestive irritation
- Dosage or usage tip: 5–10 billion CFU daily, available in capsules, powders, or chewable tablets

Slippery Elm
Slippery elm is a soothing herbal supplement traditionally used for digestive comfort. It coats the lining of the stomach and intestines, helping to calm irritation that can contribute to stool changes. This protective effect may promote healthier bowel movements and reduce discomfort.
- Mechanism of action: Forms a protective layer in the gut to reduce irritation
- Dosage or usage tip: 400–500 mg capsule taken 1–2 times daily, or as a tea made from powdered bark

Summary
Black stool can sometimes be caused by diet or supplements, but it may also signal something more serious. While probiotics can restore gut balance and slippery elm can soothe irritation, it’s important to consult a healthcare professional for proper evaluation. Supplements may provide supportive digestive health benefits but should not replace medical diagnosis or care.
