Towards the end of a rugby game, when your muscle glycogen is depleted, athletic performance starts to decline. You glance at the bench, hoping there’s a fresh option to replace you. The feeling of having emptied the tank with 15 mins still on the clock is the worst.

Luckily, Ruck Science has the solution. No2 Max is a potent nitric oxide booster designed to give you abundant energy on the rugby field so you can go a full 80 without feeling like a passenger.

L-Arginine, the active branch-chain amino acid in our No2 Max blend has been widely studied over the past 15 years for its potential endurance benefits. The main thing to understand about L-Arginine is that in some athletes, it may be metabolized to produce greater levels of Nitric Oxide in the blood.

An increased concentration of No2 provides circulatory benefits which have long been sought after by endurance athletes like ultra-marathoners. Rugby players can utilize our No2 Max to achieve greater levels of endurance during rugby games and training. But there are also a range of recovery benefits linked to better circulation. For more on this, nav over to the L-Arginine Research page.

No2 Max for Rugby Training

Because most Tuesday and Thursday rugby training sessions last at least 90 minutes, some rugby players could benefit from using No2 Max before rugby training starts. If you’re going to use our BCAA rugby supplement on training days, we suggest taking 2 tablets about 30 minutes before training and then another tablet immediately after training. If you’re a bigger player, you might need to up this dosage slightly.

No2 Max for Rugby Games

Increasing Nitric Oxide concentration in the blood should be a primary aim for endurance and high-intensity athletes alike. During rugby games, increased No2 levels provides for more efficient oxygen-carrying capacity. This means you can perform the same amount of work with less energy. We recommend using the same protocol for rugby games as for rugby training. Take 2 tablets, 30 minutes before your rugby game starts and at least 1 tablet immediately after you get off the rugby pitch.

No2 Max for Recovery

When we created our Ruck Recovery package, we made sure to include our BCAA rugby supplement. Why? Because the circulatory benefits of increased Nitric Oxide in the blood might reduce recovery times in rugby players. We suggest taking at least one tablet after any endurance activities in addition to following rugby games.

No2 Max for Circulation

There are several notable ‘side-effects’ if you will of improving your circulation and the NO concentration in your blood. Primarily, its really good for your heart. But secondly, some customers have reported an increase in libido. We don’t endorse the use of No2 Max for this purpose, but it doesn’t sound like the worst side-effect.
