How will a 200mg caffeine serving affect my day-to-day performance?

A single 12 fl oz can offers a significant boost in alertness appropriate for daytime use or when you need focused energy. It’s strong enough to help you power through work, studying, or a gaming session but still fits into a sugar-free routine.

• Supports increased wakefulness and reduced perceived fatigue
• Suitable for mid-morning or mid-afternoon pick-me-ups
• Not recommended immediately before bedtime due to caffeine strength
