What Is Protein Powder?

Protein powder is a concentrated source of protein derived from foods like milk, eggs, or plants.

The most common types include:

• Whey protein – Fast-digesting, great post-workout
• Casein protein – Slow-digesting, ideal before bed
• Plant-based protein – Vegan-friendly alternatives

It’s designed to help you increase your protein intake without having to eat large amounts of whole food.

Why Protein Matters (Even If You’re Not a Bodybuilder)

Protein isn’t just for muscle growth—it plays a key role in:

• Muscle repair and recovery
• Fat loss (keeps you fuller for longer)
• Hormone production
• Overall health

If you’re training regularly or trying to lose weight, getting enough protein becomes even more important.

How Much Protein Powder Should You Take?
