Slow-digesting protein for overnight and between meals.
Slow-digesting micellar casein — 24g protein, the classic before-bed shake.
Micellar casein with 25g protein and a slow 7-hour amino release.
No-frills unflavored micellar casein for clean overnight protein.
It is the classic use: ~30–40g of micellar casein provides a slow amino drip overnight. The effect is modest but real for those who train hard and want to maximize recovery.
Whey for fast post-workout absorption; casein for slow, sustained feeding (before bed or long gaps). Many lifters keep both, but either alone is fine if you hit your daily protein.
