Comparison
Bromantane vs Nicotinamide Riboside
Side-by-side of Bromantane 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.
Bromantane
Bromantane, the Russian nootropic sold as Ladasten (ADK-709), acts on dopamine to cut fatigue and anxiety without classical stimulant rebound.
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
Bromantane
- •Russian RCT base (Voznesenskaya 2010, n=728) supports 50 mg daily for asthenia and fatigue over 4 weeks
- •Atypical actogenic mechanism: induces tyrosine hydroxylase rather than direct monoamine release
- •Subjective profile is anxiolytic plus mildly motivating, distinct from classical stimulants
- •Long half-life of around 11 hours supports once-daily morning dosing
- •WADA-banned since 1996; relevant for tested athletes
- •Western evidence base is thin; most published trials are Russian-language and not independently replicated
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

Which Should You Take?
Nicotinamide Riboside comes out ahead for most readers on the criteria we weight: 3 catalogued goals, OTC dietary supplement, oral dosing, with a Tier-A outcome catalogued. Bromantane is the right call when one of the conditionals below applies.
- → If your priority is focus or working memory, pick Bromantane.
- → If your priority is fatigue resistance, pick Bromantane.
- → If your priority is healthspan extension, pick Nicotinamide Riboside.
- → If your priority is energy and stamina, pick Nicotinamide Riboside.
Edge case: If you want to avoid controlled substance, Nicotinamide Riboside is the more accessible choice.
Default choice: Nicotinamide Riboside. Lower friction to source, a Tier-A evidence outcome catalogued, and broader goal coverage. Reach for Bromantane only if your priority sits squarely in the goals it owns above.
