At The Nutrition Store, with over 10 years of experience in the supplement market in Barcelona, we have advised thousands of customers on the importance of slow-release proteins. These proteins are essential for those looking to maximize muscle recovery, prevent catabolism, and effectively control appetite.

In this article, you will discover what slow-release proteins are, their benefits, and the best times to take them.

What Are Slow-Release Proteins?

Slow-release proteins, also known as gradual absorption proteins, are those that the body digests and absorbs slowly, ensuring a steady supply of amino acids over time.

The main representative of this group is casein, which makes up approximately 80% of the proteins in milk. Its structure forms micelles that coagulate in the stomach, slowing digestion and providing a sustained release of amino acids.

Benefits of Slow-Release Proteins

– Prevention of muscle catabolism: During long periods without food, such as sleep, the body may break down muscle to obtain energy. Taking casein before bed helps preserve muscle mass.

– Improved muscle recovery: The sustained release of amino acids supports muscle tissue repair, especially during rest periods.

– Greater satiety and appetite control: Due to its slow digestion, casein prolongs the feeling of fullness, making it ideal for those controlling calorie intake.

– High calcium content: In addition to its protein contribution, casein is rich in calcium, benefiting bone health.

When to Take Slow-Release Proteins?

Before bed: Taking casein before sleeping ensures a continuous supply of amino acids during overnight fasting, optimizing muscle recovery.
Between meals: To maintain stable amino acid levels and prolong satiety, it is ideal to consume it between main meals.
During fasting periods: If you go several hours without eating, casein prevents catabolism and keeps protein synthesis active.

Types of Slow-Release Proteins

There are several options available on the market, but the most common are:

Micellar Casein: Extracted through chemical-free filtration, it maintains its micellar structure, ensuring a prolonged release of amino acids.
Calcium Caseinate: Obtained by adding calcium to casein, it is more soluble in water and digests slightly faster than micellar casein, but still offers sustained protein release.

Casein vs. Whey Protein: Which One to Choose?

The main difference between these proteins lies in absorption speed:

Proteïna de sèrum: Digests quickly, raising amino acid levels in a short time. It is ideal for post-workout consumption.
Casein: Digests slowly, gradually releasing amino acids. It is perfect for prolonged periods without food, such as before bed.

Consell: Both proteins complement each other, so you can use them according to the time of day and your fitness goals.

Conclusion: Do You Need Slow-Release Proteins?

Slow-digesting proteins, such as casein, are key to optimizing muscle recovery, preventing catabolism, and prolonging satiety. If you’re looking for a supplement to take before bed or between meals, this is an excellent option.
