Training

Supplementary nutrition

Supplements and sports nutrition: what matters most, which supplements have evidence (protein, creatine, caffeine), what is situation-dependent, and how to choose products wisely.

Supplements are not the foundation

Supplements are heavily marketed, but results mainly come from training, nutrition, and recovery (sleep and stress management).

Supplements can support the basics, not replace them.

Do you need supplements

  • high training volume
  • trouble reaching protein targets
  • diet restrictions
  • confirmed nutrient deficiencies
  • convenience and adherence

Protein

Protein powder is simply food protein in a convenient form. If you already hit your protein target from food, you do not need it.

Creatine

Creatine monohydrate is one of the most studied and effective supplements for strength and high-intensity work. A common approach is 3–5 g daily; loading is usually optional.

Caffeine

Caffeine can improve performance and reduce perceived fatigue, but sensitivity varies and it can disrupt sleep for some people.

What tends to work

Best evidence: protein (when needed), creatine, caffeine. Others are situation-dependent (omega-3, vitamin D, magnesium, collagen).

BALANS in practice

Train first. Then nutrition. Then recovery. Only then supplements.
