How to Choose Smelling Salts

Part of our series: Smelling Salts — The Complete Guide.

Why this is not a ranking

Search for smelling salts and most of what comes back is a ranked list: a "No. 1" pick, a "most extreme" pick, a "for beginners" pick. We are not going to write one of those, for two reasons.

First, there is no common scale to rank on. Most brands do not print the ammonia content of a bottle, fewer print a percentage, and we are not aware of any independent, published test that compares brands side by side. A list that puts one bottle above another on intensity is repeating marketing, not reporting a measurement.

Second, the way a product describes itself is exactly what the US Food and Drug Administration has acted on in this category. In August 2024 the FDA warned consumers not to buy or use certain inhalants it described as unapproved drugs marketed for alertness and energy, and named seven companies. The history is in Are Smelling Salts Bad for You? What the FDA Actually Says.

So instead of a ranking, this is a checklist: the things you can verify about a product before you pay for it.

1. Read the label before the marketing

The label is the most reliable source of information about any bottle. Look for three things on it:

• An ingredient list. You should be able to see what is in the bottle. If a listing shows no ingredients at all, ask the seller before buying.
• Caution text. Ammonia is an irritant. A label that carries no warnings about children, eyes, fire or distance from the nose is leaving out information you need.
• A company name and address. You want to know who made it and how to reach them if something is wrong with the bottle.

For reference, a Spinto bottle lists Ammonia, Lavender Oil, Lemon Oil, Nutmeg Oil and Purified Water USP, and its caution panel says to keep it away from children and from fire or flame, to keep the bottle 6 inches from the nose, and not to use it if you are allergic to any ingredient or pregnant.

2. Check the scent oils if you have allergies

Many solution-style products add fragrance or essential oils to the ammonia. Those oils are ingredients in their own right. If you react to lavender, citrus, nutmeg or anything else, the ingredient list is where you find out — before the bottle is under your nose, not after.

3. Know which format you are buying

Products sold as smelling salts come in a few different physical forms, and they are not interchangeable:

• Solution bottles — a screw-cap bottle of liquid, reused over many openings. This is the format most people mean in a gym.
• Crushable ampules — a small single-use capsule inside a cloth or paper sleeve, broken once and discarded. This is the format stocked in first-aid supply catalogs, and it is labeled differently.
• Dry or crystal preparations — ammonium carbonate in a container, the older form the name "smelling salts" comes from.

Pick the format that matches how you will actually use and store it. The chemistry behind each is covered in What Are Smelling Salts and How Do They Work?

4. Look at how the bottle is sealed

Ammonia is volatile and escapes from an open container, so the seal matters more than it would on most products. Two things to look for:

• Tamper evidence — a shrink band or similar, so you can tell whether the bottle was opened before it reached you.
• An inner liner under the cap, which holds the contents in during shipping and storage.

A Spinto bottle has both: a clear shrink band over a ribbed screw cap, and an inner liner printed "SEALED for YOUR PROTECTION." If any bottle arrives with a seal already broken, do not use it. Why the seal matters over the life of a bottle is in Smelling Salts Storage and Shelf Life.

5. Treat effect claims as a warning sign, not a feature

This is the check most buyers skip. Every one of the FDA's 2023–2024 warning letters in this category turned on how the product was described — promises about what it would do to the person using it. A listing built around those promises is describing itself the way the enforcement actions describe a problem.

A product page that tells you what is in the bottle, how it is sealed, how to use it correctly and what the risks are is giving you more useful information than one that tells you how it will make you feel.

6. Make sure you can use it where you plan to

If you compete, the product is only half the question. Federations and venues set their own rules on where ammonia may be used, and those rules differ. Check your federation's current rulebook and the meet's own rules before you pack a bottle. The positions we have verified are in Smelling Salts in Powerlifting and Strength Sports and Are Smelling Salts Legal?

7. Work out the price per bottle

Multi-packs change the math. Divide the pack price by the number of bottles, and add shipping before comparing. As an example, Spinto's current pricing comes to:

• Single bottle: $19.99
• 2-pack: $37.98 — $18.99 per bottle
• 3-pack: $53.97 — $17.99 per bottle
• 4-pack: $67.97 — $16.99 per bottle
• 6-pack: $95.98 — $16.00 per bottle

Shipping within the US is a flat $5.95, and free on any order of two bottles or more. A single bottle is $25.94 delivered; each bottle in a 2-pack is $18.99 delivered. Buying more than you will use before the bottles are opened is not a saving if they sit in a hot car — see the storage guide above.

8. Read the return policy

Because an opened bottle cannot be resold, most sellers restrict returns to unopened product. Know the window before you buy. Spinto accepts returns of unopened bottles in their original packaging within 7 days; the full terms are in the refund policy.

9. Read the safety information whichever brand you buy

None of the checks above change the basic precautions. Do not use ammonia inhalants if you have asthma or another respiratory condition, if you are pregnant, or to treat or assess a head injury, concussion, fainting or any other medical event. Keep them away from children, eyes, skin and mouth. The full list, and correct technique, is in How to Use Smelling Salts Safely.

If you want to see a label that meets the checklist above, Spinto Smelling Salts are sold as single bottles and 2–6 bottle packs, shipped from Duluth, GA.

FAQ

Which smelling salts are the strongest? There is no independent, published comparison to answer that with. Most brands do not print ammonia content, and superlatives on a label are marketing. Compare what you can verify: ingredients, seal, format and price.

What should be on a smelling salts label? An ingredient list, caution text, and the name and address of the company responsible for the product.

Are ampules the same as bottled smelling salts? No. Ampules are single-use capsules that are crushed once and discarded; bottles are resealed and used over many openings. They are labeled and sold differently.

How much ammonia is in a Spinto bottle? 0.35 g of ammonia per bottle.

Why do product claims matter when choosing? The FDA's warning letters in this category were about how products were marketed. A listing that makes promises about effects on the body is described in the same terms the enforcement actions targeted.

Is a multi-pack worth it? Only if you will use the bottles while they are still sealed and stored properly. Work out the price per bottle including shipping, and store unopened bottles capped, upright and away from heat.
