Sports Performance

Evidence-based supplements for strength, power, endurance, recovery, and physical performance.

Evidence guide

This guide compares supplements searched for sports performance, strength, power, endurance, and recovery. Useful review starts with training goal, timing, dose, tolerance, sleep, and competition rules.

How to interpret this category

  • Creatine is reviewed by strength, power, training, and consistent use, with attention to hydration and individual kidney context.
  • Caffeine fits timing, alertness, power, or endurance, but tolerance, anxiety, blood pressure, and sleep matter.
  • Beta-alanine and citrulline depend on effort type, duration, dose, paresthesia, or gastrointestinal tolerance.

Compared supplements

A

Creatine

One of the most studied supplements for strength, power, and muscle mass, with a good safety profile in healthy adults.

A

Caffeine

Stimulant with strong evidence for improving alertness, power, and endurance at appropriate doses.

B

Beta-Alanine

May improve performance during short-to-medium duration intense efforts by raising muscle carnosine.

B

Citrulline

Nitric oxide precursor amino acid studied for possible benefits in blood flow and performance.

Frequently asked questions

What should I review before choosing a sports supplement?

Goal, training type, sleep, nutrition, total caffeine, medications, medical conditions, and competition rules.

Are creatine and caffeine used the same way?

No. Creatine is usually used consistently and is less timing-dependent; caffeine depends heavily on timing, tolerance, and sleep.

Is beta-alanine relevant for every workout?

Not necessarily. It is reviewed more for intense efforts of short to moderate duration, and paresthesia may limit tolerance.

When should I seek professional guidance?

Kidney disease, hypertension, arrhythmias, pregnancy, injuries, medication use, or regulated competitions warrant professional guidance.
