Urolithin A & B

Urolithin A vs Urolithin B: what is the real difference?

BioLight Inc.

Urolithins are gut-derived metabolites of ellagitannins found in foods like pomegranate and walnuts. Among them, Urolithin A and Urolithin B stand out for their distinct yet complementary roles. Urolithin A supports mitophagy, the cellular cleanup process that renews...

How does Urolithin A support mitochondria in skeletal muscle?

BioLight Inc.

Skeletal muscle relies on dense mitochondrial networks to power every rep, stride, and recovery cycle. When mitochondrial quality declines, energy output falls and fatigue rises. Urolithin A, a gut-derived postbiotic from ellagitannins in foods like pomegranate and walnuts,...

Can Urolithin A improve muscle strength and endurance?

BioLight Inc.

Muscle strength and endurance depend on efficient mitochondria. When mitochondrial quality slips, power fades faster and recovery slows. Urolithin A, a postbiotic from pomegranate and walnuts, supports mitophagy—the cleanup of worn mitochondria—helping muscle fibers produce energy with less...

Is Urolithin A helpful in a metabolic health routine?

BioLight Inc.

Metabolic health is more than a fasting glucose number—it’s the ability to switch fuels, clear glucose after meals, and keep inflammation low. Mitochondria power these processes, and when their quality slips, tissues burn fuel less cleanly and insulin...

Can Urolithin A affect insulin sensitivity or AMPK pathways?

BioLight Inc.

Insulin sensitivity depends on clean mitochondrial energy. When mitochondria run efficiently, tissues burn fuel with less oxidative stress and respond to insulin more effectively. Urolithin A, a postbiotic from foods like pomegranate and walnuts, supports mitophagy and intersects...

Does Urolithin B offer advantages over Urolithin A?

BioLight Inc.

Urolithin A and Urolithin B act on different levers of performance and longevity. Urolithin A drives mitophagy, helping clean up worn mitochondria to support endurance and energy efficiency. Urolithin B tilts muscle protein balance toward synthesis, protecting lean...

Can Urolithin B support strength, repair, or neuroprotection?

BioLight Inc.

Urolithin B, a gut-derived metabolite from foods like pomegranate and nuts, shows a unique profile compared with Urolithin A. While A supports mitochondrial cleanup through mitophagy, Urolithin B tilts protein balance toward synthesis, reduces atrophy signals, and calms...
