Micellar Casein Protein Powder | Slow-Digesting Protein

Meet whey protein's slower-digesting cousin. 💪

Spartan Protein Micellar Casein is a milk-derived protein powder for anyone looking for a different option from their usual whey shake.

Unlike whey, which is generally digested relatively quickly, casein forms a thicker mixture during digestion and is broken down more gradually. That's why casein protein is a popular choice in the evening or when you fancy a protein shake between meals.

With 25.3g protein per stated 33g serving, Spartan Micellar Casein offers a substantial serving of protein in a different format from our Pure Whey range.

Whey for one occasion, casein for another? Plenty of room for both in the cupboard.

Why Choose Spartan Micellar Casein?

• 25.3g protein per stated serving: Milk-derived protein in a 33g portion.
• Slower-digesting than whey: Casein behaves differently during digestion.
• Milk protein source: Casein is one of the major proteins naturally found in cow's milk.
• Thicker shake texture: Casein typically mixes into a more substantial drink than whey.
• Flexible timing: An option between meals, in the evening or whenever it suits your dietary routine.
• An alternative to whey: Another way to include protein in a varied, balanced diet.

What Is Micellar Casein Protein?

Micellar casein is a type of protein derived from milk. Casein makes up approximately 80% of the protein naturally present in cow's milk, with whey accounting for most of the remainder.

Both whey and casein provide dietary protein, but they differ in how they behave during digestion.

Casein tends to form a thicker structure in the stomach, so its digestion is generally slower than whey. This gives it a different texture and makes it an alternative protein choice for different times of day.

Micellar Casein vs Whey Protein: What's the Difference?

Both come from milk. Both provide protein. The biggest practical difference is how they digest and how they feel when mixed.

Neither is automatically better for everyone. Your overall daily protein intake, diet and personal preferences still matter.

Why Do People Take Casein Before Bed?

Casein is often associated with an evening protein shake because it digests more gradually than whey.

That doesn't mean you have to take it before bed, or that bedtime automatically makes it more effective.

If you prefer a protein shake in the evening, micellar casein is one option. Equally, you can include it at another suitable time of day.

And if you're already getting enough protein from your regular meals, you may not need an additional shake at all.
