Mindsip insights from this episode:
Reassess collagen supplementation for growth and repair benefits
The argument against collagen supplementation was that it's a poor-quality protein source with low levels of the key essential amino acids needed for growth and repair.
Utilize collagen peptides to stimulate new skin protein production
These absorbed collagen peptides can bind to receptors on skin cells, triggering gene expression changes that lead to the production of new skin proteins.
Question industry-funded collagen studies for bias
A significant reason for skepticism is that most studies on collagen peptides are funded by the industry, creating a potential conflict of interest.
Take collagen for potential benefits despite uncertainty
Despite imperfect evidence, the speaker takes collagen because it's a relatively cheap and potentially effective supplement, and they don't want to miss out on benefits due to suspicion alone.
Utilize 2.5-5 grams of collagen daily for effectiveness
A meta-analysis of collagen studies found that the most frequently used effective doses were between 2.5 and 5 grams per day.
Choose 10 grams of collagen daily for optimal benefits
The speaker personally opts for a higher dose of 10 grams of collagen per day, as some studies have used this higher threshold.
Recognize absorption of di- and tripeptides for better nutrition
Contrary to older beliefs, mechanistic studies show that our bodies absorb not just single amino acids but also di- and tripeptides directly into the bloodstream.
