- ⚠nausea
Research Overview
AICAR
Salk Institute researchers demonstrated AICAR could increase endurance in sedentary mice by 44% without exercise training. Activates AMPK, triggering PGC-1α expression, mitochondrial biogenesis, and enhanced fatty acid β-oxidation.
Plecanatide
Clinical trials show plecanatide improves constipation outcomes with a generally favorable tolerability profile. Like linaclotide, it acts locally in the intestinal lumen via GC-C signaling rather than systemic hormone effects.
