Supplements for Firefighters: Helpful Boost or Expensive Hype?

As a dietitian who works with first responders, I get asked about supplements constantly. Firefighters want to know—do they really need supplements, or can they get everything from food? 

The short answer: food should always come first. 

That is, if long-term results are what you want, not an expensive band-aid

But let’s be real, on shift, it’s not always easy to hit every nutrition target with meals alone. That’s where supplements can help, but only if you know which ones are worth forking over part of your overtime check.

Food First, Always

Think of your diet like a cupcake. The base, the cake, is real food: protein, veggies, whole grains, healthy fats etc. That’s where your energy, strength, and long-term health come from. The icing? That’s your performance nutrition, specifically timing. When you eat around workouts, hydration/electrolyte timing, etc. And supplements? They’re the sprinkles. Sure, they add a little razzle-dazzle, but try living off sprinkles and you’re gonna crash harder than a rookie after their first energy drink. No supplement will save a garbage diet.

The Boring Stuff: Safety and Regulation

Here’s where I lose most people: regulations. But stick with me because this is how you avoid wasting money (or ending up with surprise side effects and fun medication interactions).

Contrary to what some influencers preach, supplements are regulated, but not like medications. The FDA (Food and Drug Administration) and FTC (Federal Trade Commission) have roles here:

  • FDA checks labels and steps in after problems show up.
  • FTC watches for false advertising claims.

But there’s a limited approval process before supplements hit the shelves. Manufacturers are expected to self-regulate, which can lead to problems for consumers. Specifically, an inaccurate ingredient amount or an ingredient/contaminant is added when it should not have been.

Third-party testing is when an independent organization (not tied to the supplement company) tests a product for quality, purity, and label accuracy. It helps confirm that what’s listed on the label is actually in the bottle, without:

  • Contaminants (heavy metals, bacteria, banned substances)
  • Accurate ingredient amounts
  • Hidden or harmful ingredients

This is especially important for pro or collegiate athletes, but it also reduces risk for general consumers and first responders. 

Look for These Trusted Seals:

  • NSF Certified for Sport
  • USP (U.S. Pharmacopeia)
  • Informed-Choice / Informed-Sport
  • Banned Substances Control Group (BSCG)

No seal? Seriously consider skipping the supplement. Third-party testing is not the end-all all be-all, but it can reduce the risk of contamination. Note that third-party testing does NOT guarantee that the supplement will work for the goal you want to achieve.

So… What Should You Take?

It depends. There’s no one-size-fits-all answer, and what works for your shift mate might not be right for you. Some supplements can be helpful for firefighters, particularly in terms of recovery, sleep, and performance, but you should always check with a doctor or dietitian first. These professionals are trained to evaluate your goals, medical conditions, current medications, and supplements. This can help prevent side effects and ensure you are not wasting your money!

Red Flags to Avoid:

🚩 Claims to “treat, prevent, or cure” anything

🚩 Buzzwords like “100% natural” (natural can be effective, and therefore also harmful)

🚩 Proprietary blends (aka: mystery mix)

🚩 Anything that promises to “detox” (detox what, exactly?)

Final Word

Supplements aren’t magic pills or shortcuts. They’re just tools, if used the right way. Focus on fueling your body with real food first. Build your cupcake, then maybe add sprinkles. Just don’t drop half your overtime on a tub of powder with wild claims and zero proof. Your body (and your wallet) deserve better.
