Cordyceps is a natural medicine mushroom used to help energy metabolism and stamina. This ingredient sits inside a six-m mushroom blend that’s grown and certified organic for quality and purity.

This form comes from organic-certified mushrooms, and the blend stresses sourcing integrity and sticking to organic standards.

What Does Cordyceps Do?

Cordyceps participates in improving oxygen utilisation and endurance during exercise, with research suggesting enhanced aerobic and anaerobic performance and delayed fatigue in trained individuals, and this is something a lot of people notice when they push hard and stay in the zone.

The mix in Peak O2 also contains other mushrooms, which help to support the primary role of Cordyceps in oxygen uptake and stamina through antioxidant and energy-producing pathways, so you get a little boost and a steadier drive.
