Peak O2

What is Peak O2?

Peak O2 is a revolutionary ingredient that is made from organic-certified six different Ayurvedic mushroom strains (Cordyceps, Reishi, King Trumpet, Shiitake, Lion’s Mane and Turkey Tail). These mushroom strains are classified as powerful adaptogen that allow athletes to adjust and overcome physical and mental stress when performing intense exercise. It is an endurance enhancer that can help trainers get the most out of their workout. 

Why Peak O2?

Peak O2 has been clinically studied to increase power and endurance in athletes. As Peak O2’s mushroom strains are grown on organic whole oats, it undergoes a specific process that preserves peak bioactivity for maximum performance.¹ After processing, Peak O2 contains high amounts of beta glucans and antioxidants that help to fight oxidative stress in the body. This in turn helps trainers to recovery faster, train longer and get back to the gym faster. Peak O2 increases your body’s ability to uptake oxygen and use it more efficiently, it elevates your workout by providing more power, endurance, and bioactivity. 

Peak O2 Benefits for Bodybuilding

Scientific research can often be a hit or miss. At the time of writing, Peak O2 has proposed the benefits for its ergogenic properties and performance enhancing properties. Supplementation that include strains of mushroom like Cordyceps has been shown to increase oxygen intake during exercise resulting in better exercise capacity.² Research has also suggested that Peak O2 may be effective for enhancing aerobic performance and delaying fatigue by improving uptake of oxygen in the body.

Peak O2 Side Effects, Negatives & Safety 

Although most of the ingredients in Peak O2 are of natural origin, there are possible side effects that include minor health problems like skin irritation, allergic reactions and dizziness. Very few studies have indicated that the ingredients from Peak O2 have any serious negative impact after consumption, but it is worth mentioning any significant side effects from these ingredients. 

Peak O2 Recommended Dosage & Ingredients

The recommended dose for Peak O2 is 1-4 grams per day and has a loading phase of 28-56 grams. One of the most recent studies indicate that using 4 grams of Peak O2 gives better results and has been the methodically validated dose for athletes.³

Peak O2 Supplements

Peak O2 can be found as a stand-alone supplement like Primaforce’s Peak O2 or in other pre-workout supplements because of its proven effects in significantly improving VO2 max time. Peak O2 can also be taken at anytime during the day. Additionally, there has been studies that Peak O2 works better in conjunction with beta-alanine and creatine monohydrate. 

Stacking Peak O2 Supplements

Peak O2 is extremely versatile and easy to use. Peak O2 can be stacked with most supplements including creatine, beta-alanine, pre-workouts, fat burners or amino acid supplements to maximise performance.  Depending on what your goals are, Peak O2 can be combined with branched chain amino acids for intra-workout gains. Alternatively, trainers have the option of stacking it with a performance protein or performance carb for improving endurance and workout intensity.
