Whether you are trying to build muscle or just supplement your diet with extra protein, whey protein is one of the most widely used, effective and affordable options you have.
Whey is one of the two main proteins in milk — the other being casein. Whey is a superior source of protein as it contains all of the essential amino acids and it is highly digestible and quickly absorbed by the body.
Concentrate vs. Isolate
There are two common variations of whey protein powders on the market: concentrate and isolate.
Whey concentrate consists of about 70-80% protein in addition to fat and lactose (milk sugar).
Whey isolate consists of about 90% protein and has lower amounts of fat and lactose.
People who are looking for a high protein and low sugar/fat supplement should opt for the isolate. It is also recommended for people who have lactose intolerance or suffer from bloating and other digestive issues when consuming dairy products.
Where to Buy Cheap Whey Protein Isolate?
Many popular sports nutrition companies offer branded whey protein blends that usually contain several other useless/filler ingredients, and they sell it at a premium price.
For those looking to save some money and pass on the overhyped proprietary formulas, sourcing supplements from bulk, generic suppliers is the way to go.
One of the best online stores that sells quality bulk supplements is HR Supplements. They have some of the cheapest whey protein powders you can find on the Internet. They sell whey protein isolate at around $20 for a 1kg bag — check it out on their official website.
This is 100% pure whey powder that has a 90% protein content. The only additive it contains is soy lecithin (unflavored). The flavored versions contain additional ingredients like artificial flavors and sweeteners.
The plain unflavored isolate does not taste very good on its own, so unless you plan on mixing it with some food, shake or another drink, you may want to consider a flavored option.
The company also makes whey protein concentrate and many other supplements which you can order from their online store at low, bulk prices. They are based in Phoenix, AZ, and they test all their products for purity in their in-house lab (COA’s available online and on request).
