The Best Types Of Protein Powders Explained For Gains

What are the differences between the best protein powders?

We’ve come to a time in history where the impossible is now attainable, and everyone is looking to improve themselves and be the best that they possibly can. As sarcastic and corny as that may sound, there’s certainly nothing wrong with wanting to improve yourself and become the best version who you are with protein powder supplements.

In fact, if you’re not trying your best to be a special and unique snowflake then you’re just not living your life the right way. You should want to be in great health, to feel as if you could jump over someone’s head or lift someone over your head. Exercise is paramount to that as well as building quality muscle to be able to perform such acts.

If you want to take your fitness to new levels then you’re going to have to put in the work not only in the gym, but in the kitchen as well. All too often people get the wrong idea about building muscle and making gains. A great many people believe that dirty bulking is the way to put on massive size, not realizing that they’re likely to put on an immense amount of fat in the process.

This is where making wise choices comes into play. The primary source of building and maintaining muscle is protein consumption. But sometimes getting the adequate amount of protein from food sources is just too hard. In this post, we will detail the best types of protein powders, the differences, benefits to each and how each can help achieve your muscle building goals.

People are always looking for the best protein powders on the market, but the reality is that in order to get exactly what you need from protein, you have to know what your choices are and what makes them the right source for you.

Whey Protein

First on the list of best protein powders is the classic whey protein. Coming from milk, whey is produced during the cheese making process, the liquid that separates from the curds. Whey is considered one of the best protein powders simply for it’s high protein content, but there are things to look out for with this particular kind of powder. It contains lactose which some people have trouble digesting, but is great for building muscle and aiding in recovery (1).


For those who suffer from lactose intolerance whey protein powder doesn’t just come in one form. Whey protein concentrate contains some lactose elements, but whey protein isolate contains very little due to the extra breakdown during the process.

Those without a problem will find whey to be a quickly digested protein. It contains branched-chain amino acids (BCAAs) which plays a major role in both muscle growth and recovery after a hard training session. Amino acid are absorbed into the bloodstream to generate the process of muscle protein synthesis which is the creation of new muscle.

Whey is one of the best protein powders because of its ability to be digested quickly.

Casein Protein

Casein Protein Powder shares similarities with Whey Protein as it is derived from milk. Casein unlike whey however is a protein that is digested more slowly. Because its digested slower than whey it means that the absorption of amino acids into the bloodstream is delayed. Though whey protein may have the edge over casein in terms of increasing muscle protein synthesis and strength, casein does have specific benefits (2).

It is still great in terms of muscle production and maintenance, however it is best consumed when you’re trying to restrict calorie intake. It allows for muscle maintenance and fat loss during a cut. It’s also great to consume casein protein before bed for better recovery as well as combating catabolism while you sleep, preserving and rebuilding your muscle mass after a hard training session.

Pea Protein

If you’re an individual with severe allergies in regards to dairy, then utilizing a pea protein powder is one of the best alternatives. Made from the high fiber legume the yellow split pea, the protein powder contains a ton of essential amino acids save for methionine. This is perhaps the biggest knock against pea protein as it’s not giving you all of the nutrients you would want out of a protein powder.

Nevertheless, pea protein does offer a nice balance. It’s absorbed in the blood stream slower than whey protein, but faster than casein. This effect can make it a great product to use in between meals to keep you satiated. Studies have also shown the individuals who utilize pea protein powders have similar muscular development to those who use whey (3). Other studies have also found that consuming pea protein can be beneficial for lowering blood pressure as well (4).
