Creatine: a gym-goers’ favorite is naturally present in beef

Creatine is a nitrogen-containing compound produced by the body from three amino acids: arginine and glycine, which form its basic structure, and methionine, which participates in the final stage of its synthesis. After being produced or obtained through food, it is transported mainly to the muscles, where part of it remains stored as phosphocreatine.

Creatine is naturally present in beef because the food consists of the animal’s muscle tissue. Meat, poultry and fish are among its main dietary sources, although the concentration may vary according to the type of food, the cut and the cooking method. The scientific review The evolving role of creatine in public health describes dietary creatine as a compound found almost exclusively in products of animal origin. My Minerva also discusses its presence in meat in the article Meat in an athlete’s diet: muscle recovery and performance.

Why is natural creatine from beef important for health?

Creatine is involved in the system responsible for the rapid regeneration of ATP, a molecule used by cells as an immediate source of energy. When the muscle performs intense work, phosphocreatine transfers a phosphate group to help replenish the ATP that has been used.

This mechanism is particularly important during the first moments of short, intense activities, such as weightlifting, jumping or sprinting. However, creatine does not act as the sole source of energy, as the body also uses carbohydrates and fats depending on the intensity and duration of the activity.

In addition, its role is not limited to athletes. The creatine-phosphocreatine system is present in the energy metabolism of everyone and also acts in other tissues with high energy demands. The review Metabolic Basis of Creatine in Health and Disease details this physiological role.

What does science say about natural creatine from beef?

Scientific literature confirms that the body produces creatine and can also obtain it through food. Meat and fish are its main natural sources, while diets without animal products usually provide very small amounts of the compound.

However, it is important to distinguish the creatine found in food from the creatine used in supplements. The scientific position stand International Society of Sports Nutrition position stand links creatine monohydrate supplementation to improvements in high-intensity exercise performance and training adaptation. These studies, however, use concentrated doses and do not show that a single serving of meat produces the same effect.

Cooking can also affect the amount of creatine present in food. Because it is water-soluble, some of it may pass into the liquid during cooking. Heating can also reduce its content by promoting the conversion of some creatine into creatinine, a compound formed through the degradation of creatine, as observed in the study Determination of creatine, creatinine, free amino acid and heterocyclic aromatic amines in meat extracts.

The presence of this compound in the context of sports nutrition is also discussed in the My Minerva article Beef and athletes: why this is a successful partnership.

Who benefits from consuming natural creatine from beef?

Everyone uses creatine in energy metabolism, regardless of whether they engage in sports. The body produces part of the compound, while food can supplement its availability.

People who eat beef and other animal-based foods obtain creatine naturally as part of their diet. Athletes and people who engage in strength training tend to have greater interest in the subject because of the demand for rapidly available energy during intense activities.

Older adults are also frequently included in creatine research because of its potential role in preserving strength and functionality. However, the results most studied in these groups mainly involve supplementation combined with exercise, rather than meat consumption alone.

For this reason, beef should be understood as a natural dietary source of the compound and other nutrients, without being presented as an automatic substitute for a prescribed supplementation strategy. My Minerva explores the combined role of diet and training in the article Demystifying red meat through science.

How can natural creatine from beef be included in the diet?

Beef can be part of meals with rice, beans, vegetables, leafy greens and other foods. Fish, poultry and other meats also contribute to compound intake. Therefore, varying protein sources helps increase the nutritional diversity of the diet.

The amount of creatine present in a meal varies according to the food, serving size and cooking method. In addition, it is not necessary to consume meat in excess in an attempt to increase muscle stores. Serving choices should take into account the overall dietary pattern, individual needs and guidance from a health professional.

When there is interest in supplementation for performance, aging or a clinical condition, the decision should be considered separately from the usual diet and assessed individually.

Myths and facts about the natural creatine found in beef

Beef naturally contains creatine

Fact. Creatine is present in the muscle tissue of animals and can therefore be found in beef, poultry and fish.

Creatine is an amino acid

Myth. Creatine is a compound produced from amino acids, but it is not classified as an amino acid. Its formation mainly involves arginine, glycine and methionine. See the review on creatine metabolism.

The human body also produces creatine

Fact. The body synthesizes creatine and supplements its availability through food when people consume foods containing the compound.

Creatine is only for athletes

Myth. The creatine-phosphocreatine system participates in everyone’s energy metabolism. Athletes receive greater attention because this mechanism is particularly relevant during short, intense exercises.

Eating meat produces the same effects as taking a creatine supplement

Myth. Meat provides creatine naturally, but in dietary amounts. Performance studies generally use standardized, concentrated doses of creatine monohydrate, which are not equivalent to a typical serving of meat.

The more meat you eat, the better your physical performance will be

Myth. Performance depends on training, energy intake, protein, carbohydrates, hydration, rest and other factors. Consuming meat in excess does not guarantee maximum muscle stores or automatically improve performance.
