Casein

Active filters

Casein is a high-quality milk protein characterized by its slow absorption, making it an ideal choice for individuals supporting long-term recovery processes. Thanks to its unique ability to form a gel in the stomach, casein provides a steady supply of amino acids for 6–8 hours, making it especially valued as a “nighttime protein” and for support between meals.

What is casein and how does it work?

Casein is one of the milk protein fractions, accounting for about 80% of the total protein content in cow's milk. The main feature of casein is its slow digestion – unlike fast-absorbing whey, casein forms a gel in the stomach, which gradually releases amino acids into the bloodstream.

This mechanism makes casein anticatabolic, protecting muscles from breakdown during long periods without food. At the same time, it supports muscle protein synthesis, enabling effective recovery and muscle growth even during sleep.

Types of casein available in supplements

🔸 Micellar Casein – the purest and most commonly used form, known for its longest absorption time (6–8 hours). Ideal before bedtime and during long gaps between meals.

🔸 Casein Hydrolysate – a pre-digested form broken into smaller peptides, which speeds up absorption while retaining prolonged effects. A good compromise between fast action and sustained release.

🔸 Calcium Caseinate – a more water-soluble and easily absorbed form, often used in extended-release protein supplements.

Effects and benefits of using casein

✅ Prolonged amino acid release – ensures a constant protein supply for many hours, minimizing the risk of muscle catabolism.

✅ Nighttime recovery support – ideal before bed, helps rebuild muscle during the most important recovery period.

✅ Protection against catabolism – effectively shields muscles from breakdown during extended fasting periods.

✅ Weight management support – the long-lasting feeling of satiety helps control appetite and increases thermogenesis associated with protein digestion.

✅ Rich in glutamine and BCAAs – provides anti-catabolic amino acids that support recovery and immune function.

Who is casein intended for?

Casein is especially recommended for athletes and physically active individuals who need support in muscle recovery after intense training. It’s an excellent choice for those building muscle mass, offering nighttime anabolic support.

It is also ideal for individuals on a calorie-restricted diet, helping preserve muscle while managing appetite. Particularly beneficial for people with an irregular meal schedule who require prolonged protein support.

Safety and possible side effects

Casein is generally a safe supplement for most people. The most common issues are bloating or stomach discomfort, usually related to lactose intolerance or milk protein allergy. Individuals with such sensitivities should consider casein hydrolysate or plant-based proteins.

To minimize potential discomfort, it is recommended to dilute the supplement in more water and introduce it gradually into your diet. Casein has no known serious side effects when used properly.

Frequently Asked Questions (FAQ)

Q: When is the best time to take casein?
A: Ideally before bed or during long gaps between meals (over 4–5 hours) when extended protein support is needed.

Q: Can I combine casein with other proteins?
A: Yes, casein complements fast proteins like whey very well. Use whey after workouts and casein before sleep.

Q: How much casein can I take daily?
A: A typical serving is 20–40g, taken 1–3 times daily depending on body weight and protein requirements.

Q: Does casein help with weight loss?
A: Yes, due to its prolonged satiety and the high thermic effect of protein digestion, it supports weight control.
