Choose sports nutrition supplements only when the question fits its direct job: they provide protein, amino acids, creatine, caffeine, electrolytes, carbohydrates, vitamins, minerals, or multi-ingredient blends marketed for training, performance, or recovery; gut health supplements instead deliver strains fibers enzymes or other ingredients aimed at a defined digestive function.
The useful distinction begins with different mechanisms. For sports nutrition supplements, examine training load and performance endpoint; for gut health supplements, examine strain identity and viable count. Feature counts are meaningful once the primary purpose is known.
