Increase time to fatigue




















For best results take 4 capsules 2 hours before training. This is due to the research suggesting that using nitrates in this period will improve exercise performance (Ref)
However, if this is not feasible you can take any time of the day. This product has no stimulants, so it is safe to take in the afternoon or evening.
The key is to be consistent each day to increase overall saturation in the body, so try to build it into a routine that works for you.
If you are using leading into a competition like a marathon or fitness event then work back and start supplementation 4 weeks prior. This is the minimum time frame we suggest to reap the benefits. You can then add extra months on to help augment better training adaptations.
If you are taking to help enhance overall training performance you can take consistently on training days.
How long until I see benefits?
As this is a unique supplement it is challenging to say exactly how long it will take to see results. However here is a breakdown from the research on the two ingredients in Peak Endurance individually.
Peak O2 - The data show that clinically proven performance benefits begin at 28 grams.
You should take 2g per day for 14 days (the dose in Peak Endurance), then continue with this leading into any event or hard training block.
The benefits are even larger when 56g is consumed (4 weeks of supplementation at 2g daily).
Nitrates - There is data to suggest that a single dose of ~450mg can be beneficial but most research is from 3 days up to 4 weeks.
How to take
Peak Endurance can be taken with food or on an empty stomach. It can be taken with water, a hydration product or a sports drink it doesn’t matter.
Common mistakes people make
As with any supplement, consistency is going to be your friend. A common mistake people make is taking the product sporadically. This can result in less-than-optimal results. This product requires you to take daily to increase the body stores so make sure you find a routine so you can be consistent.
May Improve Oxygen Utilisation: Both PeakO2® and beetroot extract have been shown to improve blood flow and oxygen efficiency. PeakO2® improves oxygen use, while beetroot's nitrate content becomes nitric oxide, which widens blood vessels (observed in studies measuring oxygen levels and blood flow).
May Increase Peak Power and Endurance: In one study, PeakO2® showed a 17.6% increase in power output over 21 days, while beetroot's nitrate content may contribute to better blood flow to muscles, supporting power, strength and muscular endurance.
May Delay Fatigue and Reduce Blood Lactate Levels: PeakO2® has been shown to reduce blood lactate levels, which delays exhaustion. Beetroot's effect on nitric oxide levels can also reduce the oxygen cost of exercise, allowing for longer performance and delaying the onset of fatigue.
May Improve Time to Exhaustion: Studies note a marked 70 second improvement in time to exhaustion with PeakO2® vs a 5 second improvement with placebo, solidifying that it may help improve time to exhaustion.
May Improve VO2 Max: An increase in VO2 max from PeakO2® indicates better cardiovascular health and efficiency, a benefit which is further supported by beetroot’s ability to improve oxygen delivery to the muscles.
