Whey isolate

Body Fortress Cheapest Protein Powder IsolateWhey isolates are generally 90% or more protein in terms of weight, and they have fewer bioactive compounds than their concentrated counterparts. They also have minimal fat and carbs. Whey protein isolates are among the purest forms of protein available, and so it is no surprise that many fitness buffs opt for them. If organic protein powder is an important factor for you, then you should take a look at our Top 4 Organic Whey Protein Isolate Supplement recommendations.

Although most lactose intolerant people can handle this form of protein powder with light soymilk, it does not suit everyone. Since whey isolates are more refined than whey concentrates, they are somewhat pricier, therefore they are probably not the cheapest protein powder.

There are a number of cheap whey isolate protein powders available in the market, but the one that stands out is Body Fortress Super Advanced Whey Isolate. It provides all the benefits that are associated with whey isolates and also lacks lactose and fat that hinder the effectiveness of other products. This is a great contender for the cheapest protein powder title if you look at the price.

Two scoops of this cheapest protein powder candidate contain 60 grams of protein and 10 grams of BCAAs. This protein powder boasts a low carb-protein ratio and is ideal for those who want to see quick results. The Body Fortress Super Advanced Whey Isolate series comes in a number of flavors, all of which taste great.

The Optimum Nutrition 100% Whey Gold Standard has been packed with whey protein isolates. It features all the extras that you could ever want from a cheapest protein powder contender, including BCAA and glutamine, but still offers minimal carbs and fats. Each serving has 24 grams of whey protein, with just 1 gram of fat and 1 gram of sugar.

Its double rich chocolate flavor will put to rest all your preconceived notions about protein powders not tasting great. Unlike other alternatives in the market, Optimum Nutrition has ensured that this protein shake is not too bland or too sweet, and best of all, does not leave an unpleasant aftertaste.

It is extremely competitive in terms of price and is among the cheapest protein powder supplements available with regards to the quantity of protein per serving. Unlike other powders with whey protein isolates, this product is not difficult to mix and does not clump together.

Whey concentrate

Gaspari Nutrition Myofusion Probiotic SeriesWhey concentrate is one of the most popular types of whey protein available in the market. It is a byproduct of the process by which cheese is manufactured. It is the cheapest protein powder because it is widely available, which is the reason why the prices are slightly lower. As compared to other forms of whey protein, whey concentrate powders are low in cholesterol and fat. They are 29% – 89% protein in terms of weight. Consider buying one of our recommended Top 3 Cheapest Protein Bars Available on the Market (which also consists of cheap whey protein) to further save on your protein costs.

Although as its name suggests, whey concentrate has a high percentage of protein, it also consists of the highest level of lactose and bioactive compounds. Therefore, those with lactose intolerance, hypertension and cardiovascular issues should look for alternative supplements.

The Gaspari Nutrition Myofusion Probiotic Series predominantly consists of whey protein concentrate, but it also contains a healthy combination of whey protein isolate, casein milk protein isolate, brown rice protein concentrate, whey protein hydrolysate and egg albumin.

Where the Probiotic series lacks in taste, it definitely makes up in terms of effectiveness, particularly if you are interested in gaining muscles in a short period of time. It has also proven itself as an effective post-workout healing drink.  Since it is heavy on proteins, it is recommended that you purchase the 2 lbs packet to ensure that you can digest it with ease.

The Body Fortress Super Advanced Whey Protein is another option for those of you looking to purchase the cheapest protein powder that has a whey concentrate base. It features the proven Super Recovery Blend that has been scientifically designed to guarantee unparalleled results. Each serving contains 7 grams of sugar and 30 grams of protein which makes it one of our favorite cheap whey protein supplements.

Whey hydrolysate

Optimum Nutrition Platinum Hydro WheyWhey protein hydrolysates are not near as popular as their isolate and cheap whey concentrate protein counterparts, but they do have a growing market. Whey hydrolysates, simply put, are hydrolyzed versions of protein isolates and protein concentrates. Therefore, they are simply more broken down versions of more popular whey proteins.

Acid, enzymes or heat are used to break some of the amino acid bonds that hold together whey isolates and whey concentrates, resulting in a more bitter but more fast-digesting protein supplement. Hydrolysates are generally not the cheapest protein powder available, and so it is only used by those who struggle to digest whole whey proteins.

The Optimum Nutrition Platinum Hydro Whey is among the best-selling whey protein hydrolysates available in the market today. It has been made using premium quality hydrolyzed whey protein isolates that guarantee quick results. This single-source protein supplement is very easy to digest.

Each serving has 30 grams of hydro whey protein, 8.8 grams of BCCAs (leucine, isoleucine and valine) and only 1 gram of fat less than 1 gram of sugar.

Although most people don’t need to use the Optimum Nutrition Platinum Hydro Whey, those with lactose intolerance or other digestive issues should not look elsewhere. This protein powder might not have the best taste nor be the cheapest protein powder, but those serious about getting in shape should be willing to compromise.


EAS Lean 15 Protein PowderCasein, like the listedcheap whey protein powders, is a milk protein derivative. Whereas whey proteins are absorbed by the digestive system quickly, casein is absorbed much more slowly and steadily. Like its whey protein counterpart, casein is also inherently tasteless. If you’re considering buying a whey-casein blend, consider one of our Best Whey Casein Blend Protein Supplement recommendations.

One reason why people prefer casein to whey proteins is that it facilitates greater fat loss due to the fact that it has higher calcium content. They also allow for greater muscle retention when one is on a low-calorie diet. Casein protein powders also enhance colon health.

There are a number of casein protein options out there. One of the most popular ones is the EAS Lean 15 Protein Powder. Each serving is only 100 calories and contains 15 grams of protein, 5 grams of dietary fiber (with 1.2 grams of prebiotics). It is one of the cheapest protein powder supplements when it comes to casein.

The EAS Lean 15 Protein Powder stands out since it combines slow-digesting micellar casein with fast-digesting whey proteins to make a blend that contains no unnecessary chemical additives.

As you can see, you should not only consider buying the cheapest protein powder, but also the type of protein powder such as casein.

Soy protein

Optimum Nutrition 100% Soy ProteinSoy proteins are by far the most popular vegetable-based protein source. It is no surprise that those who are not allergic to soy almost always opt for a blend of protein powder with a significant amount of soy since it supplies all eight essential amino acids.

Soy protein is a byproduct of soya bean. It contains just about everything that is needed for effective muscle growth, including essential fibers and isoflavones. It may not be the cheapest protein powder, but it is an ideal option for those who cannot take in lactose or gluten.

If you’re not a fan of soy flavor, you might want to test a particular brand before buying a large packet. Optimum Nutrition 100% Soy Protein has earned a name for itself for being one of the best tasting soy protein powders out there. It is very easy to mix both in water or milk and does produce quick results, especially in terms of weight loss.

Plant-based protein

Garden of Life RAW Cheapest Protein PowderPlant-based protein supplements are becoming increasingly common, especially among people who are either unable to or not comfortable consuming dairy-based alternatives. Although proteins that have been derived from plants often do not have the same concentration of proteins as dairy proteins, they don’t lack in effectiveness or nutritional value. They are not the winner when it comes to the cheapest protein powder, but they do have a lot of other benefits when it comes to health.

The Garden of Life RAW Organic Protein is among the most popular protein powders available in the market. Each serving has 17 grams of protein, including 3.8 grams of branched chain amino acids.

This non-dairy protein is ideal for vegetarians, vegans and those who are lactose intolerant and cannot digest whey concentrate or whey isolate alternatives. It is a non-GMO and soy-free protein powder.

The Orgain Organic Protein Plant-Based Powder offers 21 grams of organic protein that has been derived from chia, pea, hemp and brown rice. This premium quality organic protein also provides a mere 3 grams of carbs and 5 grams organic fiber. It has no added sugar.
