Effects at a glance
Coenzyme Q10
- •Q-SYMBIO trial showed 43% reduction in major cardiovascular events at 300 mg/day in heart failure
- •Reduces statin-induced myalgia in some patients at 100-200 mg/day per Banach 2014 meta-analysis
- •Migraine prophylaxis at 300 mg/day daily; AHS lists at Level B for prevention
- •Ubiquinol absorbs 2-3x better than ubiquinone in adults over 60
- •Plasma CoQ10 falls 15-40% with chronic statin therapy
- •Small blood pressure reduction (3-5 mmHg systolic) at 100-200 mg/day
Urolithin A
- •Gut-microbiome-derived metabolite of pomegranate and walnut ellagitannins
- •Roughly 40% of adults are 'urolithin producers' from dietary intake; ~60% are non-producers
- •Ryu 2016 (Nature Medicine) reported lifespan extension in C. elegans and muscle benefits in aged rodents
- •Andreux 2019 first-in-human trial (n=60) established safety and mitochondrial gene-expression upregulation
- •Singh 2022 (n=66, 4 months, 1000 mg/day) reported improved muscle endurance in older adults
- •Most human trial portfolio is Amazentis-funded; independent replication is thin

| Category | supplement | supplement |
| Also known as | CoQ10, ubiquinone, ubiquinol, Q10 | UA, Mitopure, ellagitannin metabolite |
| Half-life (hr) ↗ | 34 | 17 |
| Typical dose (mg) ↗ | 200 | 500 |
| Dosing frequency | 1 to 3 times daily with a fat-containing meal | daily, morning with food |

| Molecular weight | 863.36 | 228.2 |
| Molecular formula | C59H90O4 | C13H8O4 |
| Mechanism | Mobile electron carrier between Complex I/II and Complex III of the mitochondrial electron transport chain. Ubiquinol form acts as a lipid-soluble antioxidant in cell membranes and regenerates oxidized vitamin E. | Induces mitophagy via potentiation of PINK1/Parkin signaling, leading to selective degradation of damaged mitochondria. Secondary anti-inflammatory effects via NF-kB modulation. |

Safety profile
Coenzyme Q10
Common side effects
- mild GI upset (rare)
- headache (rare)
- insomnia at very high doses
Contraindications
- active warfarin therapy without monitoring (modest interaction with INR)
Interactions
- warfarin: structural similarity to vitamin K may modestly reduce warfarin efficacy; monitor INR(moderate)
- antihypertensives: additive blood pressure-lowering at high doses(minor)
- statins: statins reduce CoQ10 synthesis; CoQ10 supplementation does not affect statin efficacy(minor)
- chemotherapy (oxidative-stress-dependent agents): theoretical interference; coordinate with oncology team(moderate)
Urolithin A
Common side effects
- mild GI upset (rare)
- soft stools (rare)
Contraindications
- pregnancy and lactation (insufficient data)
- active chemotherapy (consult oncology)
Interactions
- chemotherapy agents: theoretical interaction with mitochondrial-targeting agents; consult oncologist(moderate)
Which Should You Take?
Coenzyme Q10 and Urolithin A score evenly on the criteria we weight (goal breadth, legal accessibility, evidence depth). The conditionals below should drive the decision more than any aggregate score.
- → If your priority is cardiovascular health, pick Coenzyme Q10.
- → If your priority is energy and stamina, pick Coenzyme Q10.
- → If your priority is muscle hypertrophy, pick Urolithin A.
- → If your priority is mitochondrial function, pick Urolithin A.
Default choice: either is defensible. Coenzyme Q10 edges out on goal breadth + legal accessibility; Urolithin A is the right call if your priority sits in the goals listed above.
This verdict is generated from each compound's schema (goals, legal status, evidence outcomes, dosing route). It updates automatically as our compound data evolves; the deeper read sits on each individual compound page.
