The Slow Digester
Alongside their whey protein powder, Optimum Nutrition has come out with its own Gold Standard Casein Protein powder. Many consumers have seen the capabilities of ON’s whey protein powder, but know little and shy away from the potential of their casein. The slow-digesting protein powder has respective benefits that even whey in incapable of achieving, along with some minor setbacks, both of which we will discuss here in this review.

Casein > Whey
The milk derivative casein has special benefits whey can only dream of. Casein has elements when digested, that could keep protein in your bloodstream for up to 8 hours. The proteins in casein form insoluble curds in your stomach, this makes it difficult for the digestive enzymes to break the proteins apart for digestion.
Due to the slow digestion, amino acids are delayed to release making them able to stay in your bloodstream for up to 8 hours. Also, the slow digestion makes you feel fuller longer. Whey protein, on the other hand, spikes your amino acid levels almost instantly after digested, making it hard for it to sustain in your bloodstream for no longer than 3 hours.
The slow digestion has even another benefit, and it’s a solid one. Casein has properties for muscle perseverance, the ability to resist muscle breakdown. The longer stay of protein in your bloodstream protects your body from muscle atrophy (breakdown). The most common time for muscle atrophy is while your sleeping, and that is why it is advised to take casein right before bed for it to do its magic.
A Tad Bit Pricey
The one con that casein in general has, is the price tag. Comparing the two ON powders, a bag 5lb container of whey protein powder, is around $60, while the same 5lb bag of casein can cost you $75. The reason behind this is the luxury of creating casein. In order to make casein, you need actual milk (prime material) making it cost more. Unlike whey protein, a bi-product, only requiring the making of cheese.
In conclusion, ON’s casein protein powder is a supplement you should definitely look into. The casein does not receive the same amount of love as whey even though it should. Optimum Nutrition Gold Standard Casein Protein gets the go-ahead from us.
