Frequently asked questions

Why choose casein over whey protein before sleep?

Whey protein digests rapidly within 1 to 2 hours, leaving muscles without sustained amino acid delivery during a full night of rest. Micellar casein clots gently in the acidic environment of the stomach, releasing amino acids slowly over 7 to 8 hours to protect muscle tissue during overnight fasting.

How long does micellar casein take to absorb in the body?

Micellar casein takes between 7 and 8 hours to fully digest and absorb. This sustained release makes it the optimal protein source before bedtime or during extended periods without regular meals.

How do you make a thick protein pudding using casein?

Mix one scoop of casein powder in a bowl with 150 to 200 ml of cold water, milk, or unsweetened almond milk using a spoon or small whisk. Add liquid gradually until you reach a smooth, pudding-like consistency, then refrigerate for 10 to 15 minutes before serving.
