Gold Standard 100% Isolate - Optimum Nutrition

Gold Standard 100% Isolate provides premium whey protein isolate, also known as WPI (Whey Protein Isolate). Depending on the flavour, it makes up 94–95% of the formula in two forms. For maximum effect, it contains both conventional isolate and hydrolysate. The raw ingredient undergoes ultrafiltration, a membrane process that separates whey according to molecule size. The result is an isolate high in protein and low in sugar and fat.

Each 100 g contains 83 g of protein, accounting for approximately 90% of its energy value. The product is also low in fat and sugar, with no more than 1.4 g of fat and 1.1 g of sugar, depending on the flavour. A single 30 g serving therefore provides 25 g of protein and a complete spectrum of essential amino acids (EAAs), including BCAAs. You can choose from three flavours: chocolate, vanilla and strawberry.

Whey concentrate contains around 70 to 80% protein; the remainder consists of lactose, fat and minerals. Ultrafiltration takes the process further. The whey is forced through a membrane that allows water and lactose, for example, to pass through but retains the protein. The result is a raw ingredient containing minimal lactose and fat.

Part of the protein complex also consists of hydrolyzed isolate, meaning protein that has been enzymatically broken down into shorter peptides. This is the same process that would occur during digestion, but part of it takes place during production. Hydrolyzed whey is one of the fastest-absorbing and most expensive forms of whey protein.

Whey contains BCAAs (valine, leucine, isoleucine) and glutamine as part of its structure, so they do not need to be added to the product separately. One serving contains 5.5 g of BCAAs and 4.3 g of glutamine and glutamic acid.

With 25 g of protein per serving, BCAAs account for roughly one-fifth of the total protein content, which is typical of high-quality whey protein.

Whey is also a complete protein containing all nine essential amino acids (EAAs) and achieves the maximum PDCAAS score of 1.0.

When mixed with milk, the drink will be creamier than when mixed with water.
