3 Casein Sources

Casein gives you all the essential amino acids you need + a high amount of leucine to shift your body’s protein synthesis into high gear. And, you can keep it in high-gear for long. As a slow-digesting protein, casein works through the night to help reduce muscle breakdown.

23g Protein

23+ g of protein from 3 high-quality casein sources: milk protein isolate, micellar casein, and calcium caseinate. Each source blends synergistically with one another to facilitate the development and repair of muscles, as well as calcium intake.

1g Sugar

Sugar: it’s bad for your gut and it’s bad for your weight. CASEIN-3X contains only 1 g of sugar. But, less sugar doesn’t have to equal boring taste. With 2 decadent flavours (Triple Chocolate and Vanilla Frosting), you can enjoy amazing taste without the insulin spike.



If you have a gluten sensitivity, you’re always on the hunt for the right product. Our solution? A high-quality protein source formulated without gluten to be 100% safe for you … without, of course, compromising effectiveness, protein content, or taste.

Leucine, isoleucine, and valine – 3 key BCAAs that’ll get you through every step of your athletic journey. Increase protein synthesis, build muscle mass, and metabolize fats faster than ever. Finally, a supp that can keep up with your level of ambition.

In the world of sports supplements, nutrition is key but taste is king. With every Precision product we create, we follow this simple, yet crucial rule to score high on the flavour scale. Try our two decadent flavours (Triple Chocolate and Vanilla Frosting) and get hooked.

You’re working hard to maintain your physique at peak level. You’re putting in the time and you’re seeing the results. Last thing you want to do is mess it up. With less than 1 g of fat, CASIEN-3X will keep your fat as low as possible, while still increasing protein intake.

Leucine is the key ingredient your body needs to kickstart muscle protein synthesis. It directly activates a critical compound in the muscle called mTOR. In turn, mTOR helps maintain muscle mass and the key relationship between anabolic and catabolic processes.

How is CASEIN-3X different from other casein products on the market?

CASEIN-3X is a blend of 3 casein sources: Micellar Casein, Calcium Caseinate, and Milk Protein Isolate. Why 3? Each source was carefully selected for their targeted benefits:

Micellar Casein, the purest form of casein, is one of the highest quality caseins on the market today. It is highly anabolic and gradually released into the muscle over several hours. This is what allows for continuous protein synthesis, even when you’re resting.

Calcium Caseinate is a rich source of calcium – a key component that helps you develop strong bones and teeth while replacing stores lost through perspiration.

Milk Protein Isolate is the secret behind the smooth, creamy consistency and rich taste that makes CASEIN-3X the preferred choice among athletes.

What do you do to ensure an ethical and high-quality product?

We recognize that you’re a committed athlete who doesn’t cut corners – you want your gains to come from hard work and hard work alone. Integrity is just as important to us. That’s why all of our supplements are manufactured in a Health Canada site-licensed facility that is 100% free of banned substances. We also rigorously test each of our products to ensure supreme quality – always safe, always powerful.

Is CASEIN-3X safe to stack with other Precision products?

Absolutely. Stack CASEIN-3X with GLUTAMINE and MEGA-Z to increase performance even further.

Is there an age restriction I should be aware of?

CASEIN-3X is safe for adults above the age of 18.

When is the best time to take CASEIN-3X?

Take CASEIN-3X before bed to keep your body in an anabolic state while you sleep, or, as a supplement to help meet your daily protein requirement.
