Most people take creatine for the gym. It is actually really useful against insomnia.

by

for a long time Creatine has been seen as a supplement intended for people who go to the gym to have a good muscle. However, this is changing completely to recommend that anyone take creatine for the many benefits of taking creatine to improve cognitive functions for example. Now, it is also being seen that it has a great component for the quality of life in people who suffer insomnia. Sleep deprivation. The human brain represents only 2% of body weight, but consumes 20% of our body’s total energy. The main cfuel it has is ATPthe currency we use, and its ability to quickly resynthesize it determines our mental agility. But when there is sleep deprivation, energy levels drop and with it attention, memory and mood. This is where creatine comes in, as a large study published in Nature in the year 2024which changed what we knew about acute creatine supplementation in anyone. In this case, the researchers demonstrated that a single high dose of creatine is capable of reversing the cognitive deficit caused by little sleep. The results. Specifically, after 21 hours of wakefulness, the subjects showed a significant improvement in processing speed and working memory from taking creatine. Furthermore, one of the effects of stopping sleep is brain acidification. In this case, creatine acts as a buffer, preventing drops in pH and positively altering the relationship between key metabolites such as phosphocreatine and inorganic phosphate. A discovery that complements the classic 2006 study which already indicated that doses of 20 grams a day for a week mitigated the deterioration in prefrontal cortex tasks and improved mood and balance after 24 hours without sleep. Neuroprotection. As we age, the efficiency of cellular energy production decreases, which is why science is focusing on creatine as an agent. anti aging powerful. Something that is especially focused on women who are in perimenopause and postmenopause, where the protective effect of estrogens has been lost. Of course, there is an important change in the dosage, since while the standard dose is 3-5 g, women over 40 may need between 8 and 10 g/day to see notable improvements in cognitive function and mitigation of hormonal “brain fog.” Furthermore, in women, in addition to improving cognition, there is also an improvement in the quality of muscle mass, which is a critical factor for longevity. Older adults. A systematic review of 2025 and ESCEO studies directly associate creatine consumption with better cognitive health in adults over 60 years of age. In this case, creatine appears to compensate for the natural reduction of phosphocreatine stores in the aging brain, improving sustained attention and reducing mental fatigue. The new paradigm. In this way, science is advancing to see that creatine is not just a matter of gaining muscle, since the brain is also a great consumer of this energy. The reality we have on the table is that creatine is one of the compounds most tested in humans, with an excellent safety profile even at high doses. But in addition to all this, it is also the property that working memory has, since it is undoubtedly the most tangible benefit that we can have in the case of doing complex tasks that require great mental effort under very adverse conditions.

To enter the best “mental gym” in the world you don’t need a ticket: just language

by

Learning languages ​​is something that For many it is essential with the aim of opening up new job opportunities or being able to travel without problems. But beyond practical usefulness, in everyday life it can also be good insurance for our brain in the long term by acting as a barrier against cognitive decline. Analyzing data from more than 86,000 people in 27 European countries, a study published in Nature Aging has put figures on something that neuroscience has been suspecting for many years: speaking several languages ​​not only broadens our mind or allows us to watch series in their original version, but also the brain stays younger. An AI model. Behind the study is an artificial intelligence model designed to estimate the so-called “biobehavioral age.” This means that a patient’s real age will be compared with what their body reflects with the results of their analysis, how their brain works or whether they have diabetes or hypertension. This is not an algorithm that has been created by chance, but has been developed by a European consortium of neuroscientists and measures this gap and classifies those who age slower or faster with a higher biological age. When applying this model, the results were clear: multilingualism acts as a powerful protective factor against the deterioration associated with the passage of time. The more language, the better. For researchers, we are facing a phenomenon that is ‘dose-dependent’, and it is something that has been seen after removing different variables such as socioeconomic context, years of education or migratory patterns. In fact, multilingualism emerged as a “cognitive reserve” factor comparable to regular physical exercise or a healthy diet, both considered pillars of brain health. The bilingual brain: a gym that never closes. Jason Rothman, a neuroscientist at Lancaster University and an expert on bilingualism, describes it as a form of permanent training: “Every time the brain selects one language and suppresses another, attention, memory and executive control networks are activated, the same ones that tend to deteriorate with age.” These networks, which are located in specific areas of the brain, are ultimately responsible for cognitive flexibility and decision making. The more they train, such as alternating languages, the more resilient they will become. There are discrepancies. If we look at other studies carried out in the past, the truth is that people do not always think alike. Numerous large-scale analyzes point to the existence of publication biases such as lack of replicability and, especially, that many advantages attributed to bilingualism are diluted or disappear once other factors such as education or socioeconomic status are carefully controlled. An illustrative example is Lehtonen’s work in 2018which reviewed more than 150 studies and concluded that the benefits in memory, inhibitory control or cognitive flexibility are not systematic or universally replicable, and usually depend on the type of cognitive tasks used, cultural and contextual differences or the profile of bilingual speakers. It’s not a miracle. The message that predominates today among the majority of specialists is one of caution and nuance. Learning several languages ​​can be positive for cognitive development, enhance mental flexibility in certain circumstances or delay symptoms of deterioration in certain profiles, but it is not a “universal vaccine” against brain aging. Education, continued intellectual activity, socioeconomic level, physical exercise and a healthy diet maintain a much higher weight, and often, the benefits attributed to bilingualism reflect these concomitant factors more than a direct effect of speaking several languages.

Science is moving creatine from the gym shelf to a more relevant one: cardiovascular health

by

When we think of creatine, the mental image It is almost always that of a gym: someone shaking a white powder in a shaker to get more strength or a faster sprint. However, science has greatly expanded the focus on this compoundand its applications are reaching unexpected places, such as cardiology consultations. Opinion of cardiologists. The surprise recently popped up on the podcast I have a plan where cardiologist Aurelio Rojas claimed that creatine “is one of the most essential supplements” that he uses in his patients with a dose of between three and five grams daily. This statement, which may seem shocking at first, is actually the tip of the iceberg of a large body of scientific literature that attempts to explore how apply creatine in daily clinic of a doctor with his patients. But what does a sports performance supplement have to do with the heart? And does science support this enthusiasm? Muscle motor. To understand the connection, you first have to understand what creatine does. Simply put, creatine is key in cellular bioenergetics, especially by facilitating rapid production of ATP, which is essential for muscle and heart function. Creatine monohydrate is most researched and recommended way for supplementation, as an improvement in muscle contractility, performance and exercise tolerance has been seen. in the heart musclecreatine acts by stabilizing energy metabolism and may have a relevant role in situations of heart failure or ischemic diseases. Within the scientific literature It is highlighted that creatine and phosphocreatine depletion is characteristic in failing hearts, and exogenous administration can contribute to the metabolic protection of the myocardium.​ Furthermore, there is scientific interest in the potential role creatine protector on the vasculature in risk populations, by reducing chronic inflammation and contributing to better control of carbohydrate and lipid metabolism.​ Beyond the gym. All this means that the interest of cardiologists goes beyond gyms and the number of repetitions they can do in a specific exercise. One of the first diseases where emphasis is placed is heart failure and its supplementation with creatine. Although it is not a cure, the findings suggest which can improve muscle strength, endurance and exercise capacity in these patients. By improving the energy efficiency of the musculoskeletal system, the overall workload of the heart is reduced. Sarcopenia. A medical term that refers to the loss of muscle mass and strength related to age and chronic illness. It is a silent enemy that drastically worsens the prognosis of cardiological patients. and here is where creatine shinessince it is essential to increase muscle mass, especially when combined with resistance training. For a 70-year-old patient who has lost muscle mass after a cardiac event, regaining the strength to get up from a chair or climb stairs is essential. Creatine, in this context, is not an aesthetic supplement, it is a therapeutic tool to improve quality of life as they point out. the studies. It doesn’t work for everything. Creatine is not perfect. It is excellent for very intense, short-duration exercises that need immediate energy such as sprinting or lifting weights. But in low-intensity and long-duration exercises such as a marathon it is of no interest, since the aerobic metabolism of the muscle that maintains constant ATP production endogenously. The myths. Despite being a really studied supplement, creatine continues to spread myths. The ISSN is categorical about this In his review, he gives the following points: Does not damage the kidneysas long as the doses recommended by scientific evidence are followed. Obviously, if there is an underlying kidney problem, you should consult your doctor. It is not known if it causes baldness, or at least the scientific evidence has not been able to state it categorically. This is something that points to a study that showed an increase in DHT, but its relationship with hair has never been proven. It is not a steroid. It is a natural organic compound, made up of three amino acids, that the body produces and that we also ingest when eating meat or fish. In this way, science has moved creatine from the bodybuilding shelf to the general health shelf. Its ability to manage cellular energy makes it a valuable tool not only for athletes, but also, as Dr. Rojas points out, for clinical populations struggling with muscle weakness and energy depletion.

Creatine is the Queen of Gym. Now science investigates if you can also wake up your brain when you don’t sleep

by

Creatine is, together with Powder proteins Already the Ashwagandha, one of the star supplements if we do physical activity Intense. It is one of the most studied supplements and evidence on improvements in physical function are clear. However, in recent years he is calling attention to areas far from the gym thanks to its potential benefits for cognitive function. And now there are those who are studying the effects of creatine in People with lack of sleep. Creatine and brain. The operation of creatine is simple. It is a compound that we produce naturally, mainly in the liver, but that we can also obtain thanks to certain meats and fish. The problem is that in vegan lifestyles or within the framework of intense training, supplementation becomes very interesting To increase those immediate reserves of energy Recently, the Texas A&M University He discovered that creatine is not only useful in the muscles, but also in the brain, with studies pointing to positive effects on the Recovery of brain injuriesin reducing the sensation of fatigue and as a neuroprotective agent by showing potential to reduce mitochondrial dysfunction, being a key factor in the neurodegenerative diseases. Neurogenesis. Creatine plays a very relevant role in the formation of New cells and brain tissuesalso in the creation of neurons in the embryonic phase. And that prominence is what encouraged research on creatine functions in the brain. As we read in BBCwithin the tests that are being done, one is that of Ali Gordjinejad, researcher at the Forschungszentrum Jolich Center in Germany. As we discussed before, they have been carried out, and they are still doing, studies that relate the role of creatine in the brain beyond that embryonic phase, and something that disrupts the usual functioning of the brain is the sleep deprivation. That is where Gordjinejad wondered if creatine can have a role in the short -term memory and brain recovery in People with sleep deprivation. This would be interesting for people who must travel at night, emergency service workers or students who hurry before exams. The analysis. To do this, his team recruited 15 people and divided them into groups. One was given a creatine supplement and another placebo. The shot was at 6:00 p.m. and, until 9:00 in the next morning, he tested the cognitive performance of those people every two and a half hours. He analyzed his reaction times or short -term memories and discovered that the processing speed was higher in the group that took creatine. Gordjinejad Consider That, in that stress situation for the body and, above all, the brain, the organ needs energy available quickly, taking it from phosphocreatine deposits that have been filled just before exercise. Would act exactly as it does when we are doing a Intense exercise To endure, for example, one more repetition. Controversial. The researcher believes that his findings show the potential of creatine to help overErebro starts its repair mechanisms. Now, although there are very forceful studies, this is somewhat less due to an important detail: the participants in the study took 10 times the recommended daily dose of creatine. Gordjinejad himself points out that it is such a high dose that it should not be taken by people with kidney problems, but even if you are perfectly healthy, that dose can cause stomach pains or problems in the following deposits. You have to continue studying. What the researcher is clear is that we must continue to investigate until finding evidence that supports his theory or, on the contrary, help to leave it aside (that is also the scientific purpose, in short). In following trials, he will try with smaller doses, and is something that will allow creatine to relate more evidently to cognitive function. Because, as we said, Its muscle benefits in exercise They are evident and well supported by science, but when we talk about the performance of this supplementation in the brain, various researchers have agreed that you have to standardize amounts of creatine in the analysis and, above all, update those studies. A clear example is that of researcher Terry McMorris, which in 2024 and after reviewing 15 studies, concluded that there is no clear evidence that supports that creatine improves cognitive function, being the main problem that many of these studies were carried out almost a century ago and in unstricted situations. In what McMorris and Gordjinejad shake hands is in the belief that it is an area in which it is worth continuing.
