    Creatine without supplements: food sources and body synthesis

    Creatine comes from both endogenous synthesis and animal foods. A sports-supplement loading regimen is not a statement of the amount everyone must obtain from food.

    The body contributes as well as the diet

    ODS describes creatine synthesis in the liver and kidneys using amino-acid precursors and identifies meat and fish as dietary sources. Creatine and phosphocreatine support rapid energy provision in muscle through the ATP system. [1]

    The presence of creatine in a food does not imply that the food supplies the same concentrated exposure used in supplementation trials. Dietary choice and a performance intervention answer different questions. [1]

    Do not turn a study protocol into a nutritional requirement

    A person avoiding animal foods still has endogenous creatine synthesis. Whether a supplement fits a particular training goal is a separate assessment, rather than a conclusion that the diet is automatically deficient in an essential vitamin. [1]

    Eating more of a creatine-containing food also changes protein, calories and other nutrients. Trying to reproduce a loading dose through very large food portions is not an evidence-based requirement derived from the physiology. [1]

    Compare the whole intervention

    Imagine a study uses concentrated creatine while a meal contains a modest dietary amount. The meal cannot be assigned the study’s effect simply because the ingredient occurs in both. Training, total diet and exposure remain different.
