Fitness Supplements Can Improve Your Workout
The right supplements at the right time can genuinely enhance your training performance. Here's how to use them effectively.

Can supplements actually make your workouts better? The short answer is yes — but with important caveats.
At Dexter Tenison Fitness, we’ve seen supplements make a meaningful difference for clients who already have their training and nutrition dialed in. They won’t fix a bad program, but they can enhance a good one.
How Supplements Support Performance
Before Your Workout
Caffeine is the most reliable performance enhancer available. 150-300mg taken 30-45 minutes before training increases energy, focus, and endurance. Most pre-workout supplements use caffeine as their primary active ingredient.
Citrulline malate improves blood flow to working muscles, enhancing endurance and reducing fatigue during high-rep training. Look for 6-8 grams in your pre-workout.
Beta-alanine buffers lactic acid, allowing you to push through more reps before that burning sensation forces you to stop. The tingling sensation is harmless.
During Your Workout
For sessions under 60 minutes, water is sufficient. For longer or more intense sessions, an electrolyte drink helps maintain hydration and performance.
BCAAs (branched-chain amino acids) were once popular during workouts, but research now suggests they’re unnecessary if you’re eating adequate protein throughout the day.
After Your Workout
Protein within a couple hours of training supports muscle recovery and growth. A protein shake is convenient, but a whole food meal works just as well.
Creatine doesn’t need to be timed around your workout. Taking 5 grams daily at any time builds up your stores and supports training quality over time.
Timing Matters More Than Most People Think
The best supplement taken at the wrong time loses effectiveness. Caffeine too late in the day ruins your sleep. Protein too infrequently leaves gaps in recovery. Creatine skipped for days loses its accumulated benefit.
Consistency and timing together determine whether supplements help or waste your money.
Realistic Expectations
At Dexter Tenison Fitness, we’re honest about what supplements can and can’t do:
- They can give you 5-10% more performance
- They can’t replace consistent training and good nutrition
- They work best when everything else is already in place
- They’re the last 5% of the equation, not the first
Get your training, nutrition, and sleep right first. Then let supplements push you that extra bit further.
