Your Kid Asked for a Pre-Workout
Don't panic. Actually, it's kind of a good sign.
It means they're taking training seriously. They're in the gym. They want to perform better. That's a healthy impulse. The question isn't whether they should care about performance — it's making sure what they put in their body is appropriate for their age.
I started taking pre-workout at 14. I'm not going to tell you that was the smartest decision — it wasn't. But I turned out fine, and I've spent 14 years since then learning exactly what's in these products. Here's what I'd tell my own parents if I could go back in time.
What Pre-Workout Actually Is
At its core, pre-workout is just a combination of ingredients designed to give you energy, focus, and better performance during a workout. The main ingredients in most pre-workouts:
- Caffeine — the same thing in your morning coffee. Doses range from 100-400mg per serving (a cup of coffee is about 95-150mg).
- Citrulline — an amino acid that improves blood flow. Gives you a better "pump." Completely safe.
- Beta-Alanine — makes your skin tingle for 20 minutes. Improves endurance. Harmless.
- Creatine — the most studied supplement in history. Improves strength and power. Sometimes included in pre-workouts.
- B-vitamins — energy vitamins. Same stuff in a multivitamin.
That's the core of most pre-workouts. If a product has only these ingredients, it's basically caffeinated workout fuel with some performance aminos.
Where It Gets Complicated
Some pre-workouts go beyond the basics and include stronger stimulants:
- DMHA (Octodrine) — a powerful stimulant. Think of it as your coffee's coffee. Legal for adults, but significantly more intense than caffeine. Probably not ideal for a teenager's first pre-workout.
- DMAA — even stronger. Banned by the FDA, banned by NCAA, banned by every sports organization. If it's in a pre-workout, skip it entirely.
- Yohimbine — a fat-burning stimulant. Can cause anxiety and blood pressure spikes. Not great for developing bodies.
- PEA (Phenethylamine) — mood enhancer. Short-acting but intense. NCAA banned.
Here's how I explain it to parents: caffeine is like your morning coffee. DMHA is like a triple espresso with a shot of adrenaline. Both "work." One is a lot more appropriate for a first-timer, especially a teenager.
Age-Appropriate Recommendations
Ages 13-15: Start With the Basics
Honestly? Most 13-15 year olds don't need a pre-workout at all. Their natural energy is through the roof. A banana and a glass of water before training is genuinely sufficient.
If they really want something: a small dose (half scoop) of a basic pre-workout with 100-150mg caffeine, citrulline, and beta-alanine. No exotic stimulants. That's like having a cup of coffee before the gym — not extreme.
Ages 16-17: Standard Pre-Workout is Fine
By 16-17, a standard pre-workout with 200-300mg caffeine and performance ingredients is reasonable. Most high school athletes at this age tolerate it well. Just avoid the hardcore "extreme" products with DMHA, DMAA, or stacked stimulants — those are formulated for experienced adult users.
Age 18+: Full Adult Options
At 18, they can make their own informed decisions. All options are on the table. Even at this point, I'd recommend starting moderate and working up rather than jumping straight to the strongest pre-workout on the shelf.
What to Look For on the Label
When your kid brings home a pre-workout (or asks you to buy one), flip it over and check:
Green flags:
- Caffeine Anhydrous (100-300mg range)
- L-Citrulline or Citrulline Malate
- Beta-Alanine
- Creatine Monohydrate
- L-Tyrosine
- Taurine
- B-Vitamins
- Third-party certification logo (NSF Certified for Sport, Informed Sport)
Yellow flags (not dangerous, but stronger):
- Caffeine over 300mg per serving
- Multiple caffeine sources (caffeine + guarana + green tea = stacked caffeine)
- "Proprietary blend" with hidden doses — you can't verify caffeine content
Red flags (avoid for teenagers):
- DMHA / Octodrine / 2-Amino
- DMAA / Methylhexanamine
- Yohimbine / Rauwolscine
- Synephrine / Bitter Orange
- Higenamine
- Any ingredient you can't find on Google
The Caffeine Question
"But it's just caffeine, right? I let them drink Starbucks."
Fair point. Here's the context:
| Source | Caffeine |
|---|---|
| Starbucks Grande Latte | 150mg |
| Starbucks Grande Cold Brew | 200mg |
| Monster Energy | 160mg |
| Celsius | 200mg |
| Average pre-workout | 200-350mg |
| Hardcore pre-workout | 350-400mg |
If you're okay with your kid drinking a Starbucks Cold Brew, a pre-workout with 200mg of caffeine is in the same ballpark. The difference is that pre-workouts sometimes combine caffeine with other stimulants that amplify the effect.
The American Academy of Pediatrics recommends adolescents consume no more than 100mg of caffeine per day. Most pre-workouts exceed that in a single serving. I'm not going to tell you what to do with that information — you know your kid better than I do. But there it is.
If Your Kid Plays School Sports
If they're a tested athlete (NCAA, NAIA, or one of the handful of states with active testing programs (NJ, IL, LA, WY — with MN conducting suspensions based on pre-workout use)), the stakes are higher. See our NCAA Pre-Workout Guide for specific rules.
For high school: most drug tests don't detect pre-workout ingredients. But coaches cannot recommend or provide any supplements. And some states (Minnesota, Virginia) have specific rules about energy drinks and pre-workouts at school events.

What I'd Actually Buy My Kid
If my own teenager asked me for a pre-workout, here's exactly what I'd get them:
First pre-workout ever (ages 14-16):
A stimulant-free pump formula. Citrulline, beta-alanine, creatine. Zero caffeine. All the performance benefits without the stimulant question. They'll get the tingle from beta-alanine (they'll think it's working — and it is), better pumps from citrulline, and better strength from creatine. Try Axe & Sledge Hydraulic (Informed Choice certified) or Bucked Up Stim-Free.
After they've been training a while (16+):
A moderate pre-workout. 150-200mg caffeine, citrulline, beta-alanine, tyrosine. Fully disclosed formula so I know exactly what's in it. Ideally third-party tested. C4 Original (NSF Certified, 150mg caffeine) is a solid starting point.
What I would NOT buy them:
Anything with DMHA, DMAA, or stacked exotic stimulants. Not because those products are evil — they're genuinely great products for experienced adult users — but because a teenager doesn't need a supercharger before they've learned to drive.

FAQ
Can a 14-year-old take pre-workout?
There's no law against it in most states (New York banned sales of certain supplements to under-18 in 2024). A half-scoop of a moderate pre-workout with 100-150mg caffeine is comparable to a cup of coffee. Start small, see how they respond.
Can a 12-year-old drink protein shakes?
Yes. Protein powder is food — it's just dried milk or plant protein. There's nothing in a basic protein shake that isn't in a glass of milk or a chicken breast. It's fine for any age.
Are supplements safe for teenagers?
Basic supplements (protein, creatine, multivitamins) are safe for teenagers. The American Academy of Pediatrics doesn't specifically recommend creatine for under-18, but there are no documented safety concerns at standard doses. High-stimulant products should be approached with more caution at younger ages.
Should I let my kid take creatine?
Creatine monohydrate is the most studied supplement in existence with an excellent safety profile. 3-5g per day. It's fine for teenagers who are actively training. It's not a steroid, it's not hormonal, and it's not banned by any organization.
At what age can you start using pre-workout?
There's no universal age. I started at 14 — earlier than I'd recommend. 16 is a reasonable starting point for a moderate pre-workout. Before that, stimulant-free pump formulas are a better option. The real answer: when they're mature enough to read a label and understand what they're taking.
I'm not a doctor and this isn't medical advice. I'm a supplement retailer who started taking this stuff way too young and learned everything the hard way. If you have specific health concerns about your kid and supplements, talk to their pediatrician or a sports dietitian.
