What Athletes Actually Need to Know About Supplements

Most athletes I train are taking something they don’t need, at the wrong time, in the wrong amount.

They saw a guy on TikTok take it. Their buddy on the team swears by it. The label had a football player on the bottle. That’s usually where the decision started and ended.

That’s the problem.

Why most athletes waste money on supplements

Supplements are the last piece of the puzzle, not the first.

If you’re not sleeping, not eating real food, not training hard, and not hydrating, no powder is going to fix that. You’re pouring water into a bucket with holes in it.

Most athletes skip the boring stuff and jump straight to pre-workout, fat burners, or whatever their favorite creator is selling. Then they wonder why they don’t feel different.

Supplements can absolutely move the needle. But only after the basics are handled.

What supplements are actually for

Think of them as fillers.

Your food, sleep, and training do 90% of the work. Supplements fill the gaps your diet and lifestyle can’t fully cover, especially when you’re training hard five to six days a week.

That’s it. They’re not magic. They’re support.

The sooner an athlete understands that, the less money gets wasted.

The three things most athletes are actually missing

Before you even think about anything fancy, there are three gaps almost every athlete I’ve ever coached has.

Fix these, and you solve most of the problems parents bring to me when their kid is tired, cramping, not recovering, or not growing.

1. Protein

Most young athletes aren’t eating close to enough protein for the amount of training they’re doing.

If you’re lifting, practicing, and conditioning multiple times a week, your body needs raw material to rebuild. Without it, you train hard and get nothing back. You stay small, stay sore, and stall out.

Real food first. Always. But when school, practice, and life get in the way, a quality protein makes hitting your numbers realistic instead of hopeful.

2. Electrolytes

Florida athletes especially. You’re sweating out way more than water.

When you lose sodium, potassium, and magnesium through sweat and don’t replace them, you get cramps, headaches, low energy, slow reaction time, and bad recovery. A lot of the “I feel off today” days come straight from this.

Water alone isn’t enough once you start training hard. Gatorade and the drinks at the gas station are mostly sugar and food dye. You need actual electrolytes.

3. Magnesium

This one almost no one talks about, and it matters more than most people realize.

Magnesium plays a role in muscle function, nervous system recovery, sleep quality, and stress. Most athletes are deficient and don’t know it. The signs are subtle. Restless sleep, tight muscles, anxious energy, slow recovery between sessions.

Dialing in magnesium is one of the easiest wins in sports performance, and it costs almost nothing.

Keep it simple

A 16-year-old linebacker doesn’t need 12 different pills and three scoops of powder a day.

Cover protein. Cover electrolytes. Cover magnesium. Train hard, eat real food, sleep seven to nine hours.

That’s the base. Everything else is bonus.

Most athletes never even get this part right, which is why they keep chasing the next product instead of fixing the foundation.

FAQ

My kid eats a lot already, does he still need protein powder? Not always. Track it for a week. If he’s consistently hitting his body weight in grams of protein per day from food, he’s fine. If not, a shake makes it realistic.

Is it safe for a 13 or 14 year old to take these? Protein is food. Electrolytes replace what you sweat out. Magnesium is a mineral. These aren’t stimulants or performance enhancers. Still, always check with your pediatrician if you’re unsure.

Do you really need electrolytes if you’re just drinking water? If you’re training hard, sweating, and playing in Florida heat, yes. Water without electrolytes actually dilutes what you have left. That’s where the cramping and foggy feeling comes from.

How long before I feel a difference? Electrolytes and magnesium, usually within a week or two. Protein shows up over months as better recovery and steadier size and strength gains. Nothing works overnight.
