Rule One Casein Vanilla Creme

We've taken the purest, most expensive form of protein known to man, isolated micellar casein, and made it even better. The result is a formula so advanced you won't find anything like it anywhere else: Rule One Casein.

The truth is out: Protein can help build muscle — but only if you take enough of it. Most proteins are incomplete, meaning they lack or are low in certain amino acids needed to build muscle. Rule One CASEIN provides the purest form of micellar casein, which has an absorption rate that's slower than other forms of protein — it keeps you feeling fuller longer and is especially effective at night when your body typically goes without food for hours.

With 25g of protein per scoop, Rule One CASEIN is specifically designed to help you get the results you want — whether it's raining or losing weight, adding size, toning up or improving your health. It's not just another product; it's your new lifestyle...your's Rule One!

100% Micellar Casein

Casein is the most abundant form of protein in milk. This slow-digesting protein source provides a steady release of amino acids into the bloodstream even hours after consumption. It is typically referred to as a 'time-released' protein and can be likened to HGH (Human Growth Hormone), which is also released slowly into the bloodstream. 

25 G Premium Protein

Rule 1 Casein contains 25g of micellar casein per scoop. High protein diets are associated with several health benefits, including increased satiety, enhanced weight loss and lean body mass gains. 


Branch chain amino acids (BCAAs) help reduce the breakdown of muscle proteins during exercise. It is recommended that individuals consume between 3-5 grams of BCAAs per serving to increase uptake and assimilation.

120 Calories

Rule 1 Casein has a low caloric content (<120 kcal), making it the perfect addition to your diet without hindering fat loss or increased body fat levels. 

Low Fat

A high protein diet can help you lose fat and build lean muscle but only if fat and carbohydrates aren't the dominant sources of energy intake. Rule 1 Casein contains less than 2g of fat, making it ideal for those on a low-fat diet or anyone who wants to keep their daily fat intake relatively low. 

Low Carbohydrates

Consuming moderate amounts of carbohydrates before exercise has been shown to improve performance, while consuming high levels after training has been shown to aid in recovery. Rule 1 Casein contains less than 6 g of carbs, making it the perfect addition to your supplement regime whether you're looking for improved performance, increased protein synthesis or muscle tissue repair and growth.

Supports Overnight Recovery

Micellar casein can 'trickle feed' nutrients into the bloodstream, repairing and building muscle tissue throughout the night when nutrient intake is least likely. This study shows that micellar casein was more effective than soy protein at increasing plasma amino acid levels during sleep and enhancing overnight whole-body protein synthesis.

Slow Digesting Protein

Micellar casein is a slowly digesting protein which means it will provide a slow, steady release of amino acids into the bloodstream. In this study, micellar casein was absorbed by muscle cells faster than egg white or soy protein during exercise. This is due to its slower absorption rate and large particle size than other proteins. It can take up to 7 hours for micellar caseins from milk to appear in the bloodstream after consumption.

Amino Acid Delivery

Micellar casein has been shown in studies to have a greater protein-sparing effect than other protein sources, leading to a decrease in amino acids within the body that can be used for gluconeogenesis and energy production (Boirie et al., 1997 & Dangin et al., 2001). This slow release of amino acids may help athletes maintain optimal levels of muscle during strenuous activities while still allowing for lean gains.
