Why teams push back
The can is rarely the real solution to low energy
- Most athletes are tired because food, sleep, or hydration is off.
- Pre-workout habits often hide an under-fueled school day.
Safer alternative
Fix the afternoon gap before reaching for a stimulant
- A banana, crackers, yogurt, or sandwich solves more than a can does.
- Water and a real snack are lower risk and easier to coach.
Hydration and sleep
The collateral damage often lands after practice
- Athletes may sleep worse, recover worse, and show up flat again the next day.
- Drinks marketed as hydration are not the same as a hydration plan.
Cardiac Risk: This Is Not a Small Number
The cardiac risk associated with energy drinks in adolescents is documented in the peer-reviewed literature.
The cardiac risk associated with energy drinks in adolescents is documented in the peer-reviewed literature. The American Academy of Pediatrics published a clinical report documenting adverse events including seizures, stroke, renal failure, and sudden cardiac death in children and adolescents following energy drink…
The mechanism is multifactorial: high caffeine doses increase heart rate and blood pressure; taurine and other compounds affect ion channels in cardiac cells; in athletes with undiagnosed structural heart abnormalities (hypertrophic cardiomyopathy being the most concerning), stimulant loads can be the trigger for…
Caffeine: The Active Ingredient Behind All of It
Let's start with caffeine because it's doing the vast majority of the work in almost every energy drink, pre-workout, and "focus" supplement on the market.
Monster Energy (16 oz)
160 mg
Red Bull (8.4 oz)
80 mg
Celsius (12 oz)
200 mg — exceeding our athlete's daily safe limit in one can
Alani Nu (12 oz)
200 mg
A typical "pre-workout" scoop
150–400 mg depending on brand

Unpacking the Energy Drink Label
Caffeine is the star, but most energy drinks bundle in several other ingredients.
Sugar
Most traditional energy drinks contain 26–54 grams of sugar per serving. This provides real, short-term energy — but…
B vitamins (B6, B12, niacin)
Every energy drink is loaded with them. The marketing implies they're energy-producing. The reality is that B vitamins…
Taurine
An amino acid that's often listed prominently. It plays roles in cardiac function and antioxidant activity. At the…
Guarana
A plant extract that contains caffeine — typically more caffeine per gram than coffee beans. When a product lists…
Proprietary blends
When you see this on a label, it means the manufacturer is not required to disclose individual ingredient doses — only…
Pre-Workout Supplements: The Riskier Territory
Energy drinks are regulated as beverages under FDA oversight.
Beta-alanine
The ingredient that causes the "tingle" sensation (paresthesia). It's a precursor to carnosine, which buffers acid in…
Citrulline
An amino acid that increases blood arginine levels, which supports nitric oxide production and vasodilation. There's…
DMAA (1,3-dimethylamylamine)
This is where the conversation gets serious. DMAA is a synthetic stimulant that the FDA has explicitly warned is not a…
DMHA, eria jarensis, synephrine
A family of stimulants that operate similarly to DMAA. Treat them the same way.
