Creatine supplementions effect on sleep and brain health

There have been a limited number of studies investigating the effects of creatine supplementation on brain function and sleep, and even fewer studies specifically examining the timing of creatine supplementation with respect to these outcomes.

One study published in 2018 investigated the effects of creatine supplementation on sleep quality in healthy young men. Participants received either a placebo or creatine supplements (20 grams per day) for 7 days, and were instructed to take the supplements either in the morning or in the evening. The study found that creatine supplementation did not significantly affect sleep quality, and there were no differences in sleep quality between the morning and evening supplement groups.

Another study published in 2020 investigated the effects of creatine supplementation on cognitive function in healthy older adults. Participants received either a placebo or creatine supplements (5 grams per day) for 24 weeks, and were instructed to take the supplements in the morning. The study found that creatine supplementation significantly improved cognitive function compared to the placebo group, but the timing of supplementation was not specifically investigated.

Overall, while there is some limited evidence to suggest that creatine supplementation may have positive effects on brain function and sleep, there is currently little research specifically investigating the effects of timing of creatine supplementation with respect to these outcomes. Further research is needed to better understand the potential effects of timing of creatine supplementation on brain function and sleep.



What have been the results on creatine supplementation studies on brain health, cognition and longevity when it comes to humans?


Creatine supplementation has been studied for its potential effects on brain health, cognition, and longevity in humans, and there is some evidence to suggest that it may have positive effects in these areas. Here are some key findings from human studies:

  1. Cognitive function: Several studies have investigated the effects of creatine supplementation on cognitive function in healthy individuals and those with neurological conditions such as Alzheimer's disease and traumatic brain injury. A meta-analysis of 24 studies published in 2018 found that creatine supplementation had a small but significant positive effect on cognitive performance, particularly in tasks requiring short-term memory and intelligence. However, the effects were more pronounced in vegetarians and those with low baseline levels of creatine. Other studies have also found positive effects of creatine supplementation on cognitive function in older adults.

  2. Brain health: Creatine has been shown to have neuroprotective effects in animal models, and some human studies have suggested that it may also have positive effects on brain health. For example, a study published in 2015 found that creatine supplementation improved brain function in healthy young adults during a cognitive task. Other studies have suggested that creatine may help to protect against the harmful effects of brain injury and neurodegenerative diseases such as Parkinson's and Huntington's disease.

  3. Longevity: Some studies have suggested that creatine supplementation may have positive effects on longevity. For example, a study published in 2017 found that creatine supplementation extended the lifespan of worms by up to 20%. While these findings are promising, further research is needed to determine whether similar effects are seen in humans.

Overall, while more research is needed to fully understand the effects of creatine supplementation on brain health, cognition, and longevity in humans, there is some evidence to suggest that it may have positive effects in these areas.

Glutathione

Glutathione   Glutathione  is a tripeptide molecule composed of glutamic acid , cysteine , and glycine . It is one of the most important antioxidants produced by the body and has a wide range of functions. Here are some of the functions of glutathione: 1. Antioxidant : Glutathione is a powerful antioxidant that neutralizes harmful free radicals and reactive oxygen species (ROS) in the body. It protects cells and tissues from oxidative damage caused by environmental toxins, radiation, and other factors. 2. Detoxification : Glutathione plays a crucial role in the detoxification of harmful substances, such as heavy metals, chemicals, and drugs. It binds to toxins and helps to eliminate them from the body. 3. Immune function : Glutathione is essential for proper immune function. It helps to activate immune cells, such as T cells and natural killer cells, which are important for fighting infections and cancer. 4. Protein synthesis : Glutathione is involved in protein synthesis, ...

Constant change and the perception of exploration

  I find that my life is an explorative adventure. I explore not just the external world. But the internal world. I explore the platonic world that could be seen to be outside of both this external and internal world. The platonic world is independent of the internal world. I feel, I should define the building blocks of this thinking out loud monologue to make things less ambiguous. Defining the internal world as the perceived world or mental world. This is more complicated than it may sound.   It is not independent of the external world. The external world being defined as a physical world that exists independent of perception. To some degree this is a philosophical discussion where there is degrees of arbitrarity or bias in the way we reason about this. Us reasoning about is involves cognition and mental processes such as awareness and neurophysiological interaction of the physical external world as input. There are further questions that needs to be considered. Where does t...
