Casein Protein
Why Choose Casein Protein?
Casein belongs to a family of phosphoproteins commonly found in mammalian milk, making up roughly 80% of the Protein in cow's milk and 20% to 60% of the protein in human milk. When used in supplementation, casein supplies amino acids, carbohydrates, and two essential minerals; calcium and phosphorus. Casein differs from whole milk protein in one key way, milk protein’s constituent ratio is 80:20 (micellar casein: whey) whereas micellar casein’s constituent ratio is 92:8 (micellar casein: whey).

ON's Gold Standard 100% Casein was the first all-micellar casein and remains the best seller. Rapid protein use is desirable immediately before and after exercise to help refuel recovering muscles, but delayed digestion and absorption may be more beneficial at other times - including bedtime when your body typically goes for hours without food. Compared to whey, it can take significantly longer...

Casein Protein Powder For Fitness
Casein belongs to a family of phosphoproteins commonly found in mammalian milk, making up roughly 80% of the protein in cow's milk and 20% to 60% of the protein in human milk. When used in supplementation, casein supplies amino acids, carbohydrates, and two essential minerals; calcium and phosphorus. Casein differs from whole milk protein in one key way, milk protein’s constituent ratio is 80:20 (micellar casein: whey) whereas micellar casein’s constituent ratio is 92:8 (micellar casein: whey). This important difference in composition is what imparts micellar casein with its distinct functional and nutritional benefits. From a functional perspective, the main difference between micellar casein and whey protein is how fast each is digested. whey protein is quickly absorbed, in roughly two hours, whereas micellar casein takes up to seven hours to be digested. This is why micellar casein protein powder is used extensively in sports nutrition to stimulate muscle growth (anabolism), prevent muscle breakdown, as well as most significantly, speed-up muscle post-exercise recovery.
Benefits of Casein Protein Powder
- Boosts Bone Density & Bone Health
- Enhances Muscle Recovery
- Highly Bioavailable Protein
- Rich in Branched Chain Amino Acids (BCAA’s)
- Slow Absorption Protein
Why Choose Casein Protein Powder?
A quality micellar casein supplement is ideal for anyone who is looking to boost muscle protein synthesis (muscle building), avoid or mitigate muscle breakdown, especially age-related muscle breakdown (sarcopenia), and associated reductions in quality of life and life expectancy. Supplementing with micellar casein is also ideal for anyone looking to improve body composition by preventing/reducing body fat accumulation, as well as wanting to reduce the nighttime fasting period and in turn, accelerate muscle recovery post-exercise. Because casein is slow to digest, it is also frequently used to help suppress appetite, regulate blood sugar, and support weight loss efforts.
Casein Protein Varieties
Micellar casein is widely available in capsule and powder form and is also frequently included in various sports nutrition blends. While potency and dosing recommendations can vary greatly from one formula to the other, for optimal benefits it’s generally suggested to consume 20–40g of casein protein before or after workouts. Always follow label instructions carefully.
Final Thoughts
When selecting your casein protein supplement, it's important to read labels carefully so as not to confuse micellar casein with caseinate. Indeed, micellar casein is the result of a natural non-denaturing mechanical process (or membrane filtration), whereas caseinate is the result of a denaturing chemical process. The method of processing is what imparts micellar casein with its unique properties and makes it uniquely suited to sports nutrition.
