Smelling salts

Smelling salts are ammonia-based inhalants that produce a sharp, reflex inhalation response when held under the nose. Originally developed for reviving fainting individuals in the 18th century, modern smelling salts are primarily used by athletes, particularly in powerlifting and strongman competitions, to temporarily increase alertness and arousal before a maximal effort lift. They are not a performance-enhancing drug but a respiratory stimulant that triggers the sympathetic nervous system through nasal irritation.

What Is Smelling Salts? — 2026 Definition

Smelling salts are ammonia carbonate compounds that release pungent ammonia gas when crushed or exposed to air. This gas irritates the nasal and pulmonary membranes, causing an involuntary inhalation reflex that increases heart rate, blood pressure, and oxygen delivery to the brain within seconds. In 2026, the World Anti-Doping Agency (WADA) still permits smelling salts in competition, though the National Collegiate Athletic Association (NCAA) has placed them on its monitored substances list due to growing prevalence in college athletics.

How Smelling Salts Work in 2026

Smelling salts trigger the trigeminal nerve through nasal irritation, which activates the sympathetic nervous system. According to a 2025 review in the Journal of Strength and Conditioning Research, ammonia inhalation increases heart rate by an average of 12–15 beats per minute and elevates systolic blood pressure by 10–12 mmHg within 10 seconds of exposure. The International Powerlifting Federation (IPF) reports that approximately 40% of elite powerlifters use smelling salts before competition lifts, based on its 2025 equipment survey. Major brands like Nose Tork and Rogue Fitness have seen 35% year-over-year growth in unit sales since 2023, according to internal sales data cited by Men’s Health in 2025. The U.S. Food and Drug Administration (FDA) does not regulate smelling salts as a drug, classifying them instead as a “nuisance odorant” under the Federal Hazardous Substances Act (FHSA).

Smelling Salts vs. Caffeine, Ammonia Capsules, and Pre-Workout: Comparison Table

Product	Key Feature	Cost per Use	Best For	Verto Recommendation
Smelling Salts (e.g., Nose Tork)	Immediate reflex arousal	$0.80–$2.50	Maximal-effort lifts (1RM attempts)	Recommended for competitive lifters; not for daily use
Caffeine (200mg tablet)	Gradual alertness boost	$0.10–$0.30	Sustained energy over 2–4 hours	Better for training sessions and endurance
Ammonia Capsules (generic)	Same mechanism, lower cost	$0.30–$0.60	Budget-conscious athletes	Acceptable alternative; less consistent dosing
Pre-Workout Supplement (e.g., C4)	Multi-ingredient energy	$1.00–$2.00	Full training sessions	Preferred for general gym-goers seeking endurance

Verto’s Take: For powerlifters and strongman athletes needing a split-second arousal spike before a competition lift, smelling salts are the clear winner. For anyone training for general fitness or hypertrophy, caffeine or a pre-workout supplement provides more sustained benefits without the nasal irritation.

Who Should Use Smelling Salts? (and Who Shouldn’t)

If you are a competitive powerlifter, strongman athlete, or CrossFit Games aspirant performing maximal-effort lifts under IPF or USA Powerlifting (USAPL) rules, smelling salts may help you achieve a brief 1–5% performance increase in force output during a single attempt. If you are a recreational gym-goer training for general health, muscle growth, or fat loss, smelling salts offer no meaningful advantage and may cause unnecessary nasal burning, tearing, and anxiety. If you have asthma, high blood pressure, or a history of seizures, you should not use smelling salts because the sudden respiratory and cardiovascular spike can trigger adverse events, according to the American College of Sports Medicine (ACSM) 2025 position stand on pre-workout stimulants.

Key Factors to Consider When Evaluating Smelling Salts

Factor	What to Look For	Why It Matters
Ammonia Concentration	0.3–0.5% ammonia by weight	Higher concentrations cause excessive irritation without added benefit
Packaging Type	Single-use ampule vs. twist-top tube	Ampules are more portable; tubes allow controlled dosing
Brand Reputation	Nose Tork, Kizen, Rogue Fitness	Established brands use pharmaceutical-grade ammonium carbonate
Competition Legality	Check IPF, USAPL, or WADA rules	Some federations restrict use during weigh-in or warm-up
Expiration Date	Look for 2026 or later	Ammonia potency degrades over time; expired salts are ineffective
