Surprising Findings

40g of casein before bed significantly increased overnight muscle protein synthesis in older men, despite age-related anabolic resistance.

It was previously thought that older adults don’t respond as well to protein due to 'anabolic resistance,' but this study shows a strong response to a single 40g dose at night.

Practical Takeaways

Older men may benefit from consuming 40g of casein protein about 30 minutes before bed to support overnight muscle repair.
