Peako2 Performance Blend

Also known as: PeakO2®, Performance Mushrooms

Overview

PeakO2® is an organic-certified blend of six adaptogenic mushrooms, primarily featuring *Cordyceps militaris*, specifically formulated to enhance physical and mental performance by improving oxygen utilization and reducing stress. This blend is mainly utilized in pre-workout and intra-workout supplements, as well as in products designed for an active lifestyle. Key benefits include improved oxygen uptake, greater ATP production, delayed fatigue, and antioxidant effects. Although research supporting its efficacy primarily comes from a few clinical studies conducted by the manufacturer, the compound's promising performance enhancement potential highlights its relevance in athletic and fitness contexts.

Benefits

Evidence-based benefits of PeakO2® include a 17.6% increase in peak power output observed within 7 days of use, and an improvement in VO₂ max by nearly 4 ml/kg/min, with an extended time to exhaustion of 65-70 seconds after 21 days of supplementation. Additional benefits include enhanced endurance, lower heart rates during exercise, and antioxidant effects that help mitigate oxidative stress. Competitive athletes and individuals engaged in high-intensity training may experience greater advantages from improved oxygen uptake and performance. However, the strength of evidence primarily relies on manufacturer-sponsored studies, necessitating future independent research to affirm these findings.

How it works

PeakO2® enhances athletic performance by increasing oxygen uptake and improving the muscles' ability to utilize oxygen, which boosts ATP regeneration and delays fatigue. The blend incorporates bioactive compounds that likely interact with cellular pathways related to energy metabolism and oxidative stress response. By supporting cardiovascular function and metabolic processes, it aids in optimizing physical performance and endurance during high-intensity exercise.

Side effects

Current research indicates that PeakO2® is generally safe when ingested as directed, with no common, uncommon, or rare side effects reported in the literature. However, caution is advised regarding potential interactions with other supplements or medications, especially ergogenic aids. Pregnant or breastfeeding women, as well as individuals with pre-existing health conditions, should consult healthcare providers prior to initiation. Due to the lack of comprehensive long-term safety studies, users should proceed with caution and monitor for any adverse reactions while utilizing the blend.

Dosage

The minimum effective dose of PeakO2® is established at 4 grams per day, which aligns with doses used in clinical trials. While the optimal dosage range has not been definitively determined, this amount has demonstrated efficacy for improving performance metrics. Timing considerations include taking the supplement before and after exercise on training days, or twice daily on non-training days. PeakO2® is available in a powdered form, typically mixed with water, though absorption factors have not been extensively addressed in the literature.

FAQs

How quickly can I expect results?

Benefits can be observed as early as 7 days after starting supplementation.

Is it safe to use with other supplements?

What is the expected outcome of using PeakO2®?

Users can anticipate improvements in power, endurance, and oxygen utilization.

Is PeakO2® a replacement for a balanced diet?

No, it should not be considered a substitute for a balanced diet and regular exercise.
