Why do I need PRE-90 energy powder?

Footballers need to take on approximately 8-10g of carbohydrates per kg of bodyweight the day before a game to be fully fuelled at kick-off. However, research has shown that academy footballers are under-fuelled by on average 200g of carbohydrate before each match, meaning they risk running out of energy in the last 20 minutes.

PRE-90 is the ideal carbohydrate loading drink, helping footballers to easily increase their carbohydrate intake.

Research in team sports has shown that Nitrates can boost blood flow so that muscles can work harder for longer, helping to improve sprint performance. PRE-90 provides 500mg of nitrates per serving.

What are the benefits?

Two servings of PRE-90 the day before a game and one with a pre-match breakfast will provide 225g of carbs, ensuring you’ll be fully fuelled for your match.

The addition of 500mg nitrates per serving may boost repeated sprint performance in the match when taken the day before a game.

Why is carb loading important?

Carbohydrate loading is the process of storing glycogen (energy) in the muscles and liver to be used on match day. This is typically done <48 hours before a match and includes increasing carbohydrate intake in and between meals throughout the day.

What are nitrates?

Nitrates are ingested and converted into Nitric Oxide. Nitric Oxide is a gaseous signaling molecule that regulates several physiological processes that are important to exercise performance, including vasodilation, mitochondrial respiration, and skeletal muscle contractility.

What is Beta-Alanine?

Beta-alanine is a non-essential amino acid. Beta-alanine improves athletic performance by reducing fatigue, increasing endurance and boosting performance in high-intensity exercises. Studies show that beta-alanine helps increase your time to exhaustion (TTE).

What are the benefits of Montmorency tart cherry?

Montmorency tart cherry juice is derived from 100% Montmorency cherries, naturally rich in anthocyanins and melatonin. Flavonoids are plant compounds that have both antioxidative and anti-inflammatory properties. Anthocyanins are a specific class of flavonoid shown to reduce oxidative stress. Melatonin is a hormone that regulates sleep and wakefulness.
