How we compare casein
Every product gets the same benchmark: 100 g protein. We divide the pack price by the amount of protein it contains and scale that to the benchmark, so a 500 g tub compares fairly with 1 kg, and powder with capsules.
price per 100 g = pack price ÷ amount of protein in the pack × 100 g
Bundle deals (e.g. "2 for 1") are included via a multiplier. Out-of-stock products are hidden by default. The ranking is never for sale; we only earn a commission if you buy through a link. Read the full method →

What is casein used for?
Casein is a milk protein that digests slowly, providing a sustained release of amino acids to muscles over 5 to 7 hours — making it ideal as a bedtime protein. Unlike whey, which is absorbed rapidly, casein forms a gel in the stomach that slows digestion and delivers a steady drip of amino acids throughout the night. This makes it particularly effective at reducing muscle breakdown during long periods without food, such as overnight fasting. It is especially popular among athletes focused on overnight recovery and body recomposition.
