Product Description

Research has demonstrated L-Citrulline’s effectiveness in reducing fatigue and increasing high intensity sport performance. This unique amino acid is derived naturally from watermelon and raises nitric oxide levels, increases blood flow, oxygen delivery to the muscle and enhances your body’s ability to remove waste toxins such as lactic acid. L-Citrulline may therefore help combat physical and mental fatigue, ideal for both increasing daily energy and providing that edge in both training and competition.

Additional Information

Amount

1 week supply, 250g Powder, 500g Powder, 1kg Powder

Suggested Use

We recommend taking between 5-6g of L-Citrulline daily with or without food. On training days, take 3g (approximately a teaspoon) 60 minutes before, and 3g within 60 minutes after your workout. On rest days, take 3g in the morning and 3g late afternoon. Please note that it may take 2-4 weeks for the full benefits of L-Citrulline to become apparent, however, increased blood flow – due to raised nitric oxide – should be noticeable within hours.
