Caffeine for Athletes: Benefits & Dosage

Caffeine is the most widely used ergogenic aid in the world — and for good reason. It consistently improves performance across a range of athletic activities.

Benefits

• Increased alertness and focus
• Improved endurance performance
• Enhanced strength and power output
• Reduced perceived exertion

Effective Dosage

3–6mg per kg bodyweight. For most athletes, this translates to 200–400mg taken 30–60 minutes before training.

Timing

Peak blood levels occur 30–60 minutes after ingestion. Half-life is 3–7 hours — avoid late-day use if sleep-sensitive.

Tolerance and Overuse

Regular high-dose caffeine use builds tolerance. Periodic reduction (not necessarily full withdrawal) can help maintain sensitivity. Avoid exceeding 400mg daily from all sources.
