Urolithin A: The Human Data on ‘Anti-Aging’ (Mitophagy, Inflammation, Muscle — What Actually Changes)
The Energy Code
Muscle outcomes: selective strength gains
Mike notes improvements in hamstring/knee torque and some endurance tests, but not universal functional gains like handgrip.
In this Energy Code Deep Dive, Dr. Mike Belkowski and moderator Don Bailey break down a 2024 systematic review, “Targeting Aging With Urolithin A in Humans," that focuses on human supplementation studies, not “eat pomegranate and hope.”
You’ll learn what Urolithin A is (and why your gut bacteria can make results wildly inconsistent), why it’s tied to “geroprotection,” and what the clinical evidence actually supports so far: dose-dependent anti-inflammatory signals, changes in mitochondrial/autophagy gene markers, and some improvements in strength/endurance — with a reality check on what didn’t move (ATP max, broad physical function, microbiome composition, body comp, cardiovascular markers in short windows).
Bottom line: promising, practical, but still early.

Key Quotes From Dr. Mike & Don:
-
“It’s like giving two people the same coffee beans, but one of them doesn’t own a coffee grinder!”
-
"It may be improving the ‘quality control and efficiency settings’ more than raw peak horsepower.“
-
“So it’s like tuning the car so it runs smoother; not necessarily making the top speed higher.”
-
"It’s not a ‘lose 20 pounds and become a triathlete’ pill.”
-
Key points-
Urolithin A is a gut-derived metabolite from ellagic acid foods (pomegranate, walnuts, berries), but many people don’t convert well. So food intake ≠ reliable levels.
-
Supplementation “skips the gut lottery” and produces higher, more consistent plasma levels than food sources.
-
The systematic review included 5 human studies / 250 healthy participants with 10–1000 mg/day for 28 days to 4 months.
-
Biggest consistent theme: dose-dependent anti-inflammatory effects (some markers improve more at 1000 mg/day over 4 months).
-
Mitochondria story is nuanced: it may improve gene expression signatures related to mitochondrial activity, autophagy, and fatty-acid oxidation—more “quality control” than peak power.
-
What it didn’t reliably do: increase maximal ATP production, consistently boost biogenesis/dynamics markers, change gut microbiota composition, or meaningfully affect body metrics/cardiovascular outcomes in short trials.
-
Muscle outcomes: some gains in specific strength/endurance measures (e.g., torque metrics; certain fatigue tests), but not universal (e.g., handgrip and broad function didn’t consistently improve).
-
Safety in these studies looked clean (no serious adverse events attributed), but the overall conclusion remains: promising—but the human aging evidence is still young and needs longer/larger trials.
