Question 1

When is the best time to take casein?

Accepted Answer

The most effective time for casein is 30-60 minutes before bedtime. During the overnight period (7-9 hours without food), casein's slow digestion ensures a continuous flow of amino acids to muscles. Casein is also suitable during longer daytime gaps when eating is not possible for 4-5 hours.

Question 2

Can casein and whey protein be taken together?

Accepted Answer

Yes, combining casein and whey provides both rapid and slow amino acid release. Whey raises amino acid levels immediately after training, while the casein component extends this effect. This combination is called "time-release" protein and is especially useful post-workout when the next meal is several hours away.

Question 3

Is casein suitable for weight loss?

Accepted Answer

Casein is an excellent diet protein choice because it maintains satiety longer than whey. Studies show that consuming casein before bed reduces next-morning hunger and daytime calorie intake. 30-40 g of casein before sleep adds only 120-160 kcal while keeping metabolism active throughout the night.

Question 4

What is the difference between micellar and hydrolyzed casein?

Accepted Answer

Micellar casein is the most natural and slowest-digesting form — it forms a gel in the stomach and releases over 6-8 hours. Hydrolyzed casein is partially pre-broken down, absorbing faster (1-3 hours). Hydrolyzed casein suits post-workout better, while micellar casein is ideal for nighttime protein.
