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...

Do Urolithin A and Urolithin B work better together?

BioLight Inc.

Urolithin A and Urolithin B target different but complementary aspects of cellular performance. Urolithin A drives mitophagy, cleaning out worn mitochondria and improving energy efficiency, stamina, and recovery. Urolithin B, supported mainly by preclinical research, influences muscle protein...

How much food do you need to make Urolithin B?

BioLight Inc.

You don’t eat Urolithin B directly. Your gut makes it after you consume ellagitannin-rich foods like pomegranate, walnuts, pecans, and raspberries. How much you produce varies with your microbiome, which is why some people see clear benefits while...

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...
