Urolithin A: Comprehensive Product Introduction
Urolithin A (UA) is a naturally occurring metabolite produced by the gut microbiota’s metabolism of ellagic acid and ellagitannins—abundant in pomegranates, nuts, and berries. It is not directly present in food but is synthesized in the body, though production varies by individual gut microbiome composition.
Core Mechanism & Key Benefits
The most well-documented function of UA is its role in mitophagy—the process of damaged, aged mitochondria, while also stimulating mitochondrial biogenesis to boost cellular energy production. This dual action supports overall cellular health and addresses age-related decline.
Key Advantages
Muscle Health & Performance
Clinical trials show UA improves muscle strength and endurance in middle-aged and older adults. A 4-month study found a 12% increase in hamstring muscle strength with 500 mg/day, and a 15% boost in cycling distance with 1000 mg/day.
It upregulates mitochondrial gene expression in skeletal muscle and lowers plasma acylcarnitines, supporting metabolic healthPMC.
Anti-Aging & Longevity
By clearing dysfunctional mitochondria, UA targets a fundamental mechanism of aging. It has been associated with reduced inflammation (lowering markers like CRP and IL-6) and delayed joint degeneration.
Preclinical research confirms its potential to extend healthy lifespan in model organisms, with human studies showing promise for healthy aging.

Safety & Dosage
Safety Profile: Generally well-tolerated. A randomized, double-blind, placebo-controlled trial found no serious adverse events; mild side effects (bloating, nausea, diarrhea) are rare and transientPMC.
Recommended Dosage: Typical doses range from 500–1000 mg/day for 8–16 weeks. FDA has established a safe intake range for food applications (250–1000 mg per serving).
Contraindications: Not recommended for pregnant/nursing women, children, or individuals with severe liver/kidney disease. Consult a healthcare provider before long-term use.
Product Forms
UA is available as a pure supplement (often in capsule or powder form) and in functional foods/beverages. It is recognized as GRAS (Generally Recognized as Safe) by the FDA, ensuring regulatory compliance for commercial use.
Why Choose Urolithin A?
UA stands out for its clinically validated mechanism and natural origin. Unlike many anti-aging supplements, it directly modulates mitochondrial health—a core driver of aging and muscle decline. It works synergistically with exercise and a healthy diet to support long-term vitality.
