Post-Workout is a vegetarian, gluten-free powder supplement that supports mitochondrial function to reduce fatigue and improve athletic performance. It contains ingredients like D-ribose, acetyl-L-carnitine, and CoQ10 that help produce ATP, the molecule that drives energy production in cells. Mitochondria in cells use ATP to power important reactions. Post-Workout's formula aims to boost ATP production and recycling to increase energy during exercise and aid muscle recovery.
