Sarcosine: Regenerate Aging Muscle - by Molecularly Starving It

Mindsip insights from this episode:
Support sarcosine production with glycine, methionine, and choline
You can potentially support your body's own sarcosine production by consuming sufficient amounts of its precursors: glycine, methionine, and choline.
Stop seeking sarcosine from food sources
Almost no food contains appreciable amounts of sarcosine, so trying to get it from sources like eggs or steak is not worthwhile.
Reevaluate research model for sarcosine in sarcopenia studies
The speaker believes using a muscle injury model is not truly representative of sarcopenia, which is a chronic, age-related condition.
Accelerate muscle recovery with sarcosine supplementation
In a muscle injury model, sarcosine supplementation resulted in less muscle cell death and faster muscle regeneration.
Boost anti-inflammatory immune cells with sarcosine
Sarcosine causes an infiltration of immune cells that are in an anti-inflammatory state, which helps foster a healing environment in tissues.
Address low sarcosine to combat sarcopenia
People suffering from sarcopenia, age-related muscle weakness and loss, have been found to have low sarcosine levels.
Starve immune cells with sarcosine to promote muscle growth
The amino acid sarcosine works by starving your immune cells in a specific way, which paradoxically helps muscle cells grow.
Prioritize exercise over sarcosine supplements for sarcopenia management
Given the early stage of the research, it is far better to 'massively over-index on exercise' than to try and optimize sarcosine levels for combating sarcopenia.
