********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!).

Episode description

Mindsip insights from this episode:

Utilize collagen peptides to stimulate connective tissue production

Emerging evidence suggests that di- and tripeptides from collagen can act as signaling molecules, binding to cell receptors to directly stimulate the production of connective tissue.

#collagen

#peptides

Recognize your body absorbs protein chunks for better nutrition

Contrary to the belief that protein is only absorbed as single amino acids, your body can and does absorb di- and tripeptides (chains of 2-3 amino acids) into the bloodstream.

Investigate collagen study's near significance for connective tissue synthesis

A key study on collagen showed a p-value of 0.09 for connective tissue synthesis, so close to the statistical significance cutoff of 0.05 that the study may have been underpowered to detect a real effect.

#collagen

#study

Focus on whey protein for muscle growth, not connective tissue

Research indicates that while whey protein effectively increases skeletal muscle protein synthesis, it does not increase the rate of synthesis for connective tissue.

#muscle

#protein

Avoid collagen for effective muscle building due to low leucine content

Collagen protein is considered a poor source for muscle building because it has one of the lowest known concentrations of leucine, the key amino acid for stimulating muscle protein synthesis.
