Best Protein Powder for Skinny Guys

If you are keen on bulking up, then you are probably thinking about the best protein powder for skinny guys. To achieve good results, eating right by loading up with proteins is often the right path to start and follow on.

You cannot bulk up if you deprive yourself protein or if you reduce your protein intake, and in some cases, it means that you may have to supplement your source of proteins, beyond what goes into your plate.

As a skinny guy, the first thing that you will need to remember as you work on bulking up is that you will not have that perfectly sculpted body overnight. There is a lot of work that will go into your search for the big arms, and you have to be ready to invest in more than you already do.

For instance, if you are eating more than enough nutritious food, it means that you have to work with your trainer on the right exercises, and you also have to choose a healthy supplementation for the proteins.

Protein powders are always a great place for you to start, but even then, you must be really careful about the varieties of protein powders on the market and the ones that will enhance your bulking goals.

Which is the best protein powder for weight gain?

Research has shown that the recommended daily allowance for protein (both for men and women) may not be enough for fat loss or the optimization of muscle building.

Therefore, protein powders would be an excellent addition in your journey to bigger arms and muscles throughout the body. Protein powders are not only convenient in their ability to aid effective weight and muscle gain, but they are also tasty

While there are several varieties and brands of protein powders on the market today, you need to bear in mind that the powders are not all created equal, and you need to check the ingredients in the powder to ensure that it will encourage the results you seek.

That said,

Here are some of the Best Protein Powders for Skinny Guys

1. Whey Protein

 Protein Powder for Skinny Guys

Whey protein is the most popular protein powders on the market, and most guys swear by it. The main reason for its popularity and also the reason why experts recommend the use of protein powders with whey has to do with the fact that whey is high in protein.

Essentially, the best proteins for muscle building are determined through the examination of their amino acid concentration, and according to research, the best protein sources are the ones with all the essential amino acids (9).

Out of the nine amino acids, 3 are crucial. These three amino acids fall into the category of the BCAAs or the Branched Chain Amino Acids, and they include valine, leucine, and isoleucine.

The BCAAs are crucial because they are important In the maximization of the synthesis of protein. These amino acids enhance the repair of any damaged muscle fibers, and in the healing, they allow or the damaged and healing fibers to grow back bigger and much stronger.

A look at the major ingredients in the protein powders show that the whey protein has the highest concentration of proteins and amino acids – not just the general essential amino acids, but it actually records a very high concentration of the BCAA leucine as well as cysteine.

Leucine and cysteine are easily digested, and leucine is a complete protein source. Since these proteins will be digested quickly, the best time for you to consume whey protein is just before your workout.The only catch is that you might be one of the individuals who are unable to digest whey.

With your body losing some of its lean muscle mass, along with the burned body fat, whey protein does an excellent job of replenishing the protein reserves. Whey protein only contains 20% of total milk proteins.

2.Casein Protein Powders

You could also opt for the casein protein powders as an alternative to whey protein powders. Casein protein powder is made from milk protein, and as long as you are not allergic to dairy products, casein would be a good choice for you.

Like whey protein, casein protein is high in the ideal/ essential amino acids. The main difference between casein and whey protein is that while the whey proteins are fast-release proteins, casein is a slow-release protein, which means that it offers a steadier and a sustained stream of amino acids to your bloodstream over an extended period of time, ensuring the continuity of muscle rebuilding.

Using casein protein powder, the microscopic muscle fibre that was traumatised from your workout will be healed faster.

Casein is made of the 80% total milk protein, and it makes a good fit for the world of protein powders because of its high mix of peptides and also the superior profile of amino acids.

The slow-release, slow-digesting features of casein protein powders mean that you need to buy this as a powder to be used at all other times outside your pre and the post-workout window, and it’s not to be taken before or during your workout.

Note, however, that the amino acids in casein will not be delivered to the muscles straight, and you might want to blend your casein protein with whey proteins. You could add in some soy protein as well. Remember that whey protein causes an exponential increase in the concentration of blood amino acids, hence an opportunity for optimal muscle growth.

Optimum Nutrition Micellar Casein Protein Powder is a great option for skinny guys looking to build their body. Casein not only supports muscle rebuilding, it may also help with weight management support by helping you feel fuller longer

3.Soy Protein

Soy Protein

For the best plant-based protein powder, you should consider soy protein powders. Soy, though low in amino acids that you need for maximum muscle building and strength, is a complete protein.

Compared to whey proteins, soy protein powders encourage protein synthesis, albeit at a slower rate than whey protein, which boasts a superior level of protein synthesis.

Though effective, you need to know that soy proteins contain compounds called phytoestrogens, which counteract the body’s natural testosterone production, affecting your performance in and out of the gym. Therefore, if you must use soy proteins, you have to use it very moderately.

4.Pea Protein

Pea Protein

Soy protein may have reached the protein powders market way before pea proteins were a thing, but the pea protein is one now one of the best proteins for muscle building if you are looking for a plant-based option.

Now, pea proteins do not have a huge amino acid profile like what you’d see in animal-based proteins, but it’s still quite effective in increasing your muscles’ strength and size.

So, if you are vegan, in search of the best protein powder, or if you are sensitive/ intolerant to the plant proteins, pea protein would be an excellent option for you.

5.Whey Hydrolysates

Also called hydrolyzed whey protein or protein peptides, the whey hydrolysates refer to a powerful class of proteins that are quickly absorbed into the body. Unlike all the other proteins you will come across, the absorption of the whey hydrolysates is the fastest, all thanks to the peptide form that the hydrolysate is in.

For their fast-absorption process, the whey hydrolysates are produced through a special process that involves the use of very low heat, mild enzymatic, and low acid processes which favor the amino acids (branched and essential amino acids) that are the most anabolic and ideal for the short-term synthesis of proteins, where the proteins make the best pre and post-workout protein powders.

6.Protein Blends

protein blends Best Protein Powder for Skinny Guys

Protein blends refer to the protein powders made of a combination of several proteins, including casein, whey, egg, whey isolates, soy protein, and the whey protein concentrates. A blend means that you will enjoy a full spectrum of quality proteins that are absorbed into the muscle cells at different rates.

As a result, the protein blends create an effective anabolic environment from the whey protein and an anti-catabolic state from casein, which you are to use at any other time, except during the pre and the post-workout windows.

That said, you should know that the whey protein powder you buy is made of some whey isolates and a whole lot more whey concentrate. The reason for this combination is that the whey isolate is usually more expensive because it’s made of higher-quality/ pure whey, and it also has a high BV/ Biological value.

The whey protein isolate also comes with more protein but a lot less lactose and fats per serving.

For example, a high-quality whey protein isolate will have a high protein concentration of between 90 and 98% while whey concentrates only have 70-85% of proteins, meaning that the isolate offers more proteins and the proteins’ absorption is fast.

Of course, the difference in concentration between the whey proteins (isolates and concentrates) would make the isolates a go-to choice for most people, but because of the high cost of the whey isolates, you may have to settle for the whey concentrate.

The good news is that whichever of the whey proteins you choose, you could easily build bigger muscles because both options are high in important proteins and amino acids.


At the end of the day, your bulking plan calls for the incorporation of enough of the best proteins, and the protein powders are an important part of the protein load up and safe mass gains. Remember that protein is also critical for the production of red blood cells, it boosts the function of the immune system, and you also need proteins for healthy skin, fingernails, and hair. All these, and for the growth of muscles.
