We are serious about your health, ask away...
What is OneFit™?
OneFit™ is a post-exercise recovery supplement with 31 powerful ingredients, including 25g of protein, 3000mg of creatine, electrolytes, vitamins, and minerals. While it’s designed for post-workout recovery, it’s appropriate to consume anytime. However, it’s best taken after exercise to maximize its benefits for muscle repair, hydration, and recovery.
How does OneFit™ compare to whey protein?
OneFit™ goes beyond whey protein by combining 31 powerful ingredients, including protein, creatine, electrolytes, vitamins, and minerals, into one convenient formula.

Its advanced hydration formula helps reduce post-workout fatigue, so you recover faster, feel stronger, and stay ready for your next session.
Does OneFit™ help with muscle recovery?
Yes, OneFit™ is specifically designed to enhance muscle recovery after exercise. Its blend of protein, creatine, and electrolytes helps repair muscles and reduce soreness.

No, OneFit™ is free from stimulants like caffeine, making it a safe and effective choice for post-workout recovery without jitters or crashes.
Will OneFit™ cause bloating after exercise?
No, OneFit™ is formulated to be light and easily digestible, reducing the risk of bloating or discomfort, even when taken after intense workouts.
How do I use OneFit™ for recovery?
Mix one sachet of OneFit™ with 300-500ml of water and consume within 30 minutes after your workout. For best results, use it 5 days a week to support muscle recovery and hydration.
Can I take OneFit™ on rest days?
Yes, you can take OneFit™ on rest days. The ingredients are non-stimulating and safe for daily use. However, it’s best used and designed for post-exercise recovery, regardless of the type of workout.
