Why Choose Micellar Casein Protein for Maximum Results?

Unlike other powdered casein, micellar casein delivers a slow, steady release of amino acids over several hours thanks to its longer digestion. This steady release gives your body protein to work with at a consistent, reliable pace, instead of getting it delivered all at once in a short burst. This helps support muscle recovery between meals or overnight, making it the perfect bedtime supplement. We stock only 100% natural casein powder, free from artificial flavours, sweeteners, and unnecessary additives. Derived from ultrafiltered cow’s milk, Top Athlete’s micellar casein protein is the ultimate recovery aid in a natural package.

What’s the Difference Between Casein Protein and Whey Protein?

Casein and whey are the true heroes of cow’s milk, making up 100% of its protein content together. While casein is the star of the show, contributing 80% of the protein content, whey makes up the remaining 20%. Both are complete proteins, containing all the amino acids the body needs for many vital functions, with essential roles in building and repairing muscle. So what’s the difference?

Casein Protein vs Whey Protein

The rate of digestion is the key difference between casein and whey for athletes, bodybuilders, and the exercise-conscious. Casein takes longer to digest than whey protein, so it delivers a slow and sustained release of amino acids over several hours — especially its micellar form.

Lots of athletes consider both proteins essential supplements, but use them at different times and before or after different activities. Quick digestion makes whey protein useful before exercise to help build muscle during exertion. While whey is considered good for building muscle, casein is used for long-term muscle recovery and repair, often taken between meals or before bedtime for an overnight recovery boost where it helps speed recovery and reduce soreness.
