********CRITIQUES, RULES, AND NOTES********

Be aware of the following rules before posting comments:
- Please do not post summaries of the video in the comments - it damages retention on the video and YouTube is less likely to promote it (these videos cost me a lot of money to produce).

Critiques of my work are welcome! Please be aware of the following notes & rules before submitting critique:

Be mindful that this content is not all encompassing on the subject at hand and is self-limited for brevity to reach a wider audience. Also, be aware that I receive hundreds of YouTube comments per day, so the only way your critique can be considered is if you follow the steps outlined below. Finally, YouTube auto-deletes links, so I do not see most comments with links attached.

RULES:
If your comment is rude, you will be banned.
If your comment is not about the studies/topics at hand (i.e. extending to other outcomes not discussed) or offers critique with no scientific basis, it is unlikely to receive a response.

If you can follow these rules, I will try to address your critique and if there is merit, I will add an AMENDMENT to the content in question and pin it so everyone can see it (thank you!).

Mindsip insights from this episode:

Critique flawed meta-analysis on creatine and memory

A prominent meta-analysis on creatine and memory is flawed because it repeatedly included the same studies, which artificially inflated the positive results.

Utilize creatine to support cognitive function under stress

Creatine's cognitive benefits are most apparent in individuals who are mentally fatigued, sleep-deprived, or aging, as it seems to come to the rescue when the brain is stressed.

Implement 20 grams of creatine daily for cognitive enhancement

The best studies for brain health suggest a loading phase of 20 grams of creatine a day for at least a week to see cognitive benefits.

Understand astrocyte barrier to enhance creatine delivery to the brain

Important glial cells called astrocytes act as a filter and lack the creatine transporter, making it difficult for creatine to enter the brain from the blood.

Increase creatine dosage for significant brain benefits

The standard 5-gram dose of creatine is likely insufficient to raise blood levels high enough to make a significant difference for the brain.

Consume 20 grams of creatine for consistent brain effects

To be on the safe side for brain effects, consuming 20 grams of creatine would likely produce a more consistent effect than 5 grams.
