Creatine Is Undoubtedly The Most Studied Substance In Supplementation, However, Understand The Cognitive Functions It May Bring.
The creatine is acclaimed for its benefits in gaining strength and muscle mass. However, despite its robust scientific backing for physical performance, it is crucial to demystify some of its promises.
Recently, experts reinforced that there is no evidence that creatine improves cognitive functions, and, more importantly, they warn that it should not be used by everyone. Understand how it works, its true benefits, and essential precautions.
Creatine: How It Works And Why It Is The Most Studied Substance
To understand creatine, it is necessary to understand how it works in the body. This natural substance, found in small amounts in foods like red meat and fish, is essential for the production of quick energy.

Scientists mixed hydrocarbons with a gold leaf, subjected them to pressure greater than that of the Earth’s mantle and heat above 1,900 °C, and ended up accidentally discovering a new compound of gold and hydrogen.
-
Scientists discover a giant crocodile that lived millions of years ago, measuring over 8 meters, which reigned in the rivers of ancient Kenya and could hunt early humans near the water.

After four years under investigation by Cade, Apple indicates that it is willing to negotiate an agreement to enable contactless Pix payments without charges on iPhones, as revealed by Lauro Jardim’s column in the newspaper O Globo in this competition dispute.

Anvisa orders the recall of a popular magnesium supplement throughout Brazil and mandates immediate suspension after identifying a compound not authorized by sanitary legislation.
Within muscle cells, creatine combines with a phosphate to form phosphocreatine, an energy reserve that the body uses in high-intensity, short-duration activities such as weightlifting and sprints.
When you perform intense exercise, this phosphocreatine quickly releases energy to resynthesize ATP (Adenosine Triphosphate), the main energy “currency” of the cells. This allows muscles to work for longer and with greater intensity, delaying fatigue.
It is by this direct and proven action on the muscular energy system that creatine has become the most studied substance in the field of sports nutrition.
Countless studies attest to its effectiveness in increasing strength, power, and muscle mass, especially in strength and explosive exercises. Its scientific backing for these purposes is vast and consistent.
There Is No Evidence That Creatine Improves Cognitive Functions: Demystifying Myths
Despite its success in physical performance, it is vital to clarify a persistent myth: there is no evidence that creatine improves cognitive functions in healthy individuals.
Although the brain uses creatine for energy, robust research has found no significant impact on memory, focus, or other mental functions in people who do not have specific creatine deficiencies or neurological conditions.
This is an important distinction, as the expectation of a generalized cognitive benefit may lead to inappropriate use.
The scientific backing of creatine is primarily focused on its role in skeletal muscle. Any claim about cognitive improvements for the general population lacks conclusive data.
It is essential to base supplement consumption on verified information with solid scientific evidence to avoid unrealistic expectations and potential disappointments.
Creatine Should Not Be Used By Everyone: Essential Precautions
Even though it is a natural and widely researched substance, creatine should not be used by everyone. Indiscriminate use or use without guidance can lead to unwanted effects or worsen pre-existing conditions.
The main concerns and reasons why creatine should not be used by everyone include:
- Kidney Problems: Individuals with a history of kidney diseases or kidney problems should avoid creatine. Although the supplement does not cause kidney damage in healthy individuals, it is metabolized by the kidneys and may overload already compromised organs. A medical evaluation before use is crucial.
- Pregnant And Nursing Women: There are not enough studies demonstrating the safety of creatine for pregnant or nursing women. Therefore, use is contraindicated in this population.
- Children And Adolescents: The use of supplements in young individuals, whose bodies are still developing, should be approached with extreme caution and only under strict medical and nutritional guidance if there is a specific need. The growing body has different nutritional demands.
- People With Specific Chronic Diseases: Patients with certain health conditions may have restrictions on the use of creatine. It is always necessary to consult a doctor or nutritionist before starting supplementation.
- Less Serious Side Effects: In some cases, the use of creatine may cause bloating, weight gain (due to intramuscular water retention, which is an expected effect of how it works), or gastrointestinal discomfort.
The scientific basis is clear: creatine is effective in improving physical performance in specific populations and under certain conditions.
However, guidance from a health professional, such as a doctor or nutritionist, is essential to assess individual need, correct dosage, and possible contraindications. Do not be swayed by exaggerated promises; safety and health should always come first.
