24 G of Highly Anti-Catabolic Micellar Casein

Optimum Nutrition's 100% Casein contains 24 grams of Micellar Casein per serving (making up 80 percent of the product). This slow-digesting protein is known for its anti-catabolic properties, which may help to reduce muscle breakdown and aid with overall recovery. 

10 G of BCAAs

The beauty of Optimum Nutrition 100% Casein lies within its BCAA content (10 grams per serving), containing 40 percent Leucine. The added BCAA support could help increase protein synthesis while promoting a positive nitrogen balance, allowing you to achieve your goals while rebuilding your muscles from any damage they have incurred during intense training sessions. 

9G EAAs 

Every scoop of ON 100% Casein provides 9 grams of Essential Amino Acids. These are the most important amino acids to support lean muscle tissue, aiding in muscle growth and repair. 5 G of BCAAs (Leucine, Isoleucine, and Valine): This formula provides an impressive 5 grams of BCAAs per serve. Each one is important, with Leucine being most responsible for protein synthesis, Isoleucine regulating glucose uptake into cells, and Valine helping to reduce mental fatigue. 

1 G Sugar 

The only sugar found within ON 100% Casein comes from the added Aminogen sweetener; this may help improve taste while also increasing amino acid bioavailability within your body.

Aminogen Enhanced

Optimum Nutrition has added a digestive enzyme called Aminogen to their 100% Casein. This enzyme is a patented blend of peptidases, breaking down peptide bonds within the protein for optimal absorption into your system. Plus, it's designed to break down milk protein isolates into specific free amino acids that are then delivered directly into your bloodstream.

Nighttime muscle recovery

Casein powder can provide you with anti-catabolic support while you sleep. It has become increasingly popular throughout recent years due to its ability to keep protein synthesis levels high during catabolic periods, which are often experienced overnight while the body enters rest mode. BCAA support will help promote nitrogen retention and should help reduce catabolism even further, making 100% Casein a solid choice to consider before bed, despite the added amino and digestive enzymes.

Creamy Vanilla Flavour

Optimum Nutrition 100% Casein is available in two flavours, Creamy Vanilla and Rich Chocolate. Both provide 24 grams of slow-digesting protein per serving, making it an excellent way to increase your daily protein intake throughout the day while also promoting muscle growth and recovery! You really can't go wrong with either one!

Suggested use:

Optimum Nutrition 100% Casein is best taken between meals and before bed. Each scoop (34 g) should be mixed with 6-18 oz of water, milk, or your favourite beverage one to two times per day. If you are also using Optimum Nutrition 100% Whey, take 1/3 of a serving of 100% Casein in the morning and another 1/3 before going to bed to help increase protein synthesis levels while you sleep. You can even add a scoop to any meal replacement formula for added high-quality protein support!
