Muscle Gain & Exercise

Supplements studied for muscle mass, strength, and physical performance.

Evidence guide

This guide compares supplements used around strength training, recovery, and body composition. The starting point is not stacking products, but reviewing training, total protein intake, sleep, tolerance, and consistency.

How to interpret this category

  • Whey protein fits best when daily protein intake does not meet the estimated target for training.
  • Creatine has a different role: it is reviewed for strength, power, and training volume, with hydration and kidney context considered when relevant.
  • Beta-alanine is compared more for intense efforts of intermediate duration; tingling is an expected dose-related effect.

Compared supplements

A

Whey Protein

Important for post-workout muscle repair and growth, with high bioavailability and a complete amino acid profile.

A

Creatine

One of the most studied and effective supplements for increasing strength, power, and muscle mass.

B

Beta-Alanine

Raises muscle carnosine levels, delaying muscular fatigue during high-intensity exercise.

Frequently asked questions

What should I review before choosing a muscle supplement?

Start with progressive training, total protein, calories, sleep, and consistency. Supplements help compare practical options, but they do not compensate for an incomplete base.

Do whey protein and creatine do the same thing?

No. Whey protein helps cover protein intake; creatine is reviewed for strength, power, and training volume. They can coexist, but they answer different needs.

Is beta-alanine necessary for everyone?

Not necessarily. It makes more sense when the sport includes intense efforts of intermediate duration. If the focus is maximal strength or insufficient protein, other comparisons may be more direct.

When should I consult a professional?

Kidney disease, pregnancy, adolescence, eating disorders, injuries, medication use, or unintentional weight changes are reasons to review the plan with a professional.
