Faster digesting protein is desirable immediately before and after exercise to help refuel recovering muscles, but slow digestion and absorption may be more beneficial at other times including bedtime when your body typically goes for hours without food. Casein products are acid sensitive and thicken in the stomach. Compared to some other proteins, it can take longer for our Gold Standard 100% Casein‚ĄĘ to be broken down into its amino acid subcomponents. By using only premium micellar casein as a protein source, we’ve created a formula that sets the standard for slow digesting protein support. 24g of Micellar Casein.



It is a type of slow releasing protein which ensures there is a constant supply of amino acids. Micellar form of Casein has had the lactose, fat and other byproducts of dairy removed from the end product reducing intolerances to this form of Protein Powder. Casein is a very slow-digesting protein source which can supply the body with amino acids for up to 7 hours. This is ideal for those times when you will be without nutrients for an extended period of time.


BCAA’s (Branched-Chain Amino Acids) are essential in supporting muscle recovery and function as they help stimulate protein synthesis resulting in muscle growth, as well as aid in the supply of energy to the muscle during exercise.¬†OPTIMUM NUTRITION – GOLD STANDARD 100% CASEIN¬†has¬†5.5g of Naturally Occurring BCAAs.¬†Branched-Chain Amino Acids are made up of three specific and essential amino acids (EAA’s): L-Leucine, L-Isoleucine, and L-Valine. Not only do these essential amino acids help in building muscle, they may also help in the prevention of muscle breakdown.

They also have an amazing anti-catabolic function preventing muscle breakdown. They achieve this by decreasing the activity of the protein breakdown pathways as well as decreasing the expression of several complexes involved in protein breakdown.¬†This means that Branched-Chain Amino Acids not only increase the body’s rate of protein synthesis, but prevents muscle catabolism and breakdown, giving a two pronged approach to building, and most importantly sustaining, lean muscle mass.


OPTIMUM NUTRITION РGOLD STANDARD 100% CASEIN contains 5g of naturally occurring Glutamine and Glutamic Acid that accelerates muscle growth and aids in recovery by prevent DOMS (Delayed Onset Muscle Soreness) .Glutamine is also an energy source for intestinal and immune cells. It also helps maintain the barrier between the intestines and the rest of your body and aids with proper growth of intestinal cells.

L-Glutamine is the most abundant amino acid in muscle tissue, but can become depleted during intense exercise – which decreases strength and lengthens recovery. Glutamine also plays an important role in protein synthesis (the creation of muscle tissue) and for best results needs to be in a positive balance.
On top of that, Glutamine is the major component in the immune factor Glutathione, a deficiency of which often leaves hard-training athletes vulnerable to colds or infections.
Athletes and bodybuilders most often take supplemental L-Glutamine before, during, and after training to improve endurance, reduce muscle breakdown, and accelerate recovery.


For the athlete or bodybuilder who takes recovery seriously Optimum Nutrition РGold Standard 100% Casein formula packs 9 amino acids necessary for growing new and preserving existing muscle mass. Do not confuse EAA’s with BCAA. Although both are needed by the body and only provided via nutrition or supplementation, EAA’s are a complete protein source, whereas BCAA are not. Research indicates that EAA’s are best used as part of your pre-workout routine, while BCAA’s are most beneficial post workout due to their higher doses.

Essential Amino Acids (EAAs) are the 9 amino acids that the body does not make and must get through food or supplementation. All of the EAAs must be present in the body to make muscle protein and promote muscle growth, recovery and repair.


Lactase enzyme is a protein that is naturally produced in the human body that breaks down lactose (milk sugar) in the body into glucose and galactose. Without enough lactase, the body has a problem to digest foods containing lactose. Lactase enzyme improves its digestion in people with people with the problem to digest lactose.


Aminogen¬ģ is a¬†protein-digesting enzyme¬†that is added to whey protein powders and supplements. This enzyme helps aid in the digestion of the protein supplement within the body while also helping to eliminate any excess bloating that may occur for some people who consume whey protein based products.


Using a shaker cup is the easiest and most convenient way to mix up a consistently great casein shake every time. Just add one heaping scoop of Gold Standard 100% Casein to your shaker cup and then pour in 10-12 oz of your preferred beverage. Cover and shake for 25-30 seconds.

BLENDER: Add one heaping scoop of Gold Standard 100% Casein to a blender filled with 10-12 oz of water, milk, or your favorite beverage. Blend for 20-30 seconds. Then add 3-4 ice cubes and blend for an additional 30 seconds.

SPOON STIRRED: If you forgot your shaker cup or don’t have time to get out the blender, you can just add one heaping scoop of Gold Standard 100% Casein to a glass filled with 10-12 oz of cold water, milk, or you favorite beverage. Then mix it up with a spoon for about 30 seconds or until powder is dissolved.
