Side-by-side of Coenzyme Q10 and Nicotinamide Riboside. Every row below is pulled from the compound schema and will update as our data grows. For deeper reads, follow through to each compound page.
Coenzyme Q10
CoQ10 supplement guide: 100 to 300 mg/day dosing, ubiquinol vs ubiquinone absorption, Q-SYMBIO heart failure data, statin myalgia evidence.
Nicotinamide Riboside
Nicotinamide riboside (NR) is the most-studied NAD+ precursor in humans. Sold as Niagen by Chromadex; raises plasma NAD+ 30-60% at 250-1,000 mg/day.
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
Nicotinamide Riboside
- •Most-studied NAD+ precursor in human trials; the original Niagen formulation by Chromadex
- •Plasma NAD+ rises 30-60% at 250-1,000 mg/day across multiple human PK trials
- •Martens 2018 reported reduced BP and arterial stiffness at 500 mg/day for 6 weeks
- •Dollerup 2018 found no insulin sensitivity change despite plasma NAD+ rise
- •Tissue NAD+ rise inconsistent; hard clinical endpoints not yet measured
- •Larger human safety database than NMN; comparable mechanistic effects

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)
Nicotinamide Riboside
Common side effects
- mild GI upset (rare)
- headache (rare)
Contraindications
- pregnancy / lactation (insufficient data)
- active cancer (theoretical, no contraindicating data)
Interactions
- pterostilbene: complementary sirtuin pathway (Basis combination)(minor)
- TMG (trimethylglycine): methylation support during high NAD+ precursor dosing(minor)
Which Should You Take?
Coenzyme Q10 and Nicotinamide Riboside 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 metabolic health and glucose control, pick Nicotinamide Riboside.
- → If your priority is healthspan extension, pick Coenzyme Q10.
Edge case: Half-lives differ materially (Coenzyme Q10 ~34 hr vs Nicotinamide Riboside ~8 hr). Coenzyme Q10 reaches steady state faster; Nicotinamide Riboside is easier to dial in if tolerability is uncertain.
Default choice: either is defensible. Coenzyme Q10 edges out on goal breadth + legal accessibility; Nicotinamide Riboside is the right call if your priority sits in the goals listed above.
