Sleep and Performance: The Most Underrated Supplement Is Free

You can nail your training and diet, but if you’re sleeping five hours a night, you’re leaving results on the table. Sleep is the most powerful — and cheapest — performance enhancer available.

What happens while you sleep

Growth hormone peaks, muscle tissue repairs, and your nervous system resets. Skimp on it and strength, focus, and recovery all suffer.

Build a wind-down routine

Dim the lights, kill the screens, and keep a consistent bedtime. Your body thrives on rhythm.

When to consider support

If you struggle to switch off, a clean magnesium or a mild sleep aid can help — but fix the habits first.
