Study Details

Brief summary:

The purpose of this research is to determine if increasing 12% of daily protein intake during the luteal phase mitigates the potential catabolic effects of progesterone on skeletal muscle. We anticipate there will be an advantageous, decreased catabolic effect with increasing protein intake during the luteal phase.

By doing this study, we hope to learn if millions of women would benefit from additional protein supplementation during the luteal phase, which may lead to decreased skeletal muscle atrophy over time. Your participation in this research will last about 4 months.
