Comparison
Creatine Monohydrate vs Nicotinamide Riboside
Side-by-side of Creatine Monohydrate 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.
Creatine Monohydrate
Creatine monohydrate supplement guide: 3-5 g/day raises phosphocreatine stores, lifts anaerobic output 5-15%, supports lean mass and cognition under sleep loss.
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
Creatine Monohydrate
- •Increases anaerobic strength and power output by ~5 to 15% across multiple training studies
- •Adds ~1 to 2 kg of lean body mass over 4 to 12 weeks, partly intracellular water and partly true tissue gain
- •Improves 1-rep max on bench and squat by ~5 to 10% versus placebo in resistance-trained adults
- •Cognitive benefit appears mainly under sleep deprivation or high mental load, less so in well-rested individuals
- •Saturation reached in ~28 days at 3 to 5 g/day, or ~5 to 7 days with a 20 g/day loading phase
- •No evidence of renal harm in healthy adults across long-term studies; caution in pre-existing severe renal disease
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
Creatine Monohydrate
Common side effects
- water retention
- mild GI upset at loading doses
- weight gain (2 to 4 lb from intracellular water)
Contraindications
- severe renal impairment
Interactions
- caffeine (high-dose acute): mixed data on ergogenic interference; chronic use appears compatible(minor)
- nephrotoxic drugs (NSAIDs, cyclosporine): theoretical additive renal strain in at-risk patients(moderate)
Nicotinamide Riboside
Common side effects
- mild GI upset (rare)
- headache (rare)
Contraindications

Which Should You Take?
Creatine Monohydrate 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 strength or hypertrophy, pick Creatine Monohydrate.
- → If your priority is focus or working memory, pick Creatine Monohydrate.
- → If your priority is healthspan extension, pick Nicotinamide Riboside.
- → If your priority is energy and stamina, pick Nicotinamide Riboside.
Default choice: either is defensible. Creatine Monohydrate edges out on goal breadth + legal accessibility; Nicotinamide Riboside is the right call if your priority sits in the goals listed above.
