With so many options out there, what is the best protein powder for building muscle?

In order to get an answer to that question, let’s first take a look at protein itself.
There are two main sources of protein out there: whole food protein and supplement protein.
Whole food protein is, as you guessed, protein that comes from natural food sources, such as beef, chicken, fish, etc. The best forms of whole food proteins for building muscle are chicken, turkey, lean red meat, fish, eggs, and dairy.
If you’re vegetarian, your best options are eggs, low-fat cottage cheese (Organic Valley is my favorite brand), low-fat European style (Greek) yogurt (0% Fage is my favorite), tempeh, tofu, quinoa, almonds, rice, and beans.
While we’re on the subject of vegetarianism, some people claim that you must carefully combine your proteins if you’re vegetarian or vegan to ensure your body is getting “complete” proteins (all of the amino acids needed to build tissue). This theory and the faulty research it was based on was thoroughly debunked as a myth by the Massachusetts Institute of Technology, yet it still hangs around. While it’s true that some sources of vegetable protein are lower in certain amino acids than other forms of protein, there is no scientific evidence to prove that they lack them altogether.
Protein supplements are powdered or liquid foods that contain protein from various sources, such as whey (a liquid remaining after milk has been curdled and strained in the process of making cheese), egg, and soy (the three most common sources of supplement protein).
You don’t NEED protein supplements to gain muscle, but it can be impractical to try to get all your protein from whole foods every day.
What You Need to Know About Eating Protein:
There are a few things you should know about eating protein.
First is the subject of how much protein you can absorb in one sitting. Studies relating to this are very contradictory and disputed, mainly because it’s a complex subject. Your genetics, metabolism, digestive tract health, lifestyle, and amount of lean mass are all important factors. But in the spirit of keeping things simple, here’s what we know: you can eat and properly use a lot of protein in each meal. How much, exactly? Well, your body should have no trouble absorbing upwards of 100 grams in one sitting.
That said, there aren’t any benefits of eating this way (I find gorging quite uncomfortable, actually), but it’s good to know in case you miss a meal and need to make it up by loading protein into a later meal.
Another thing to know about protein is that different proteins digest at different speeds and some are better utilized by the body than others. Beef protein, for example, is digested quickly and 70-80% of what’s eaten is utilized by the body (the exact number varies based on what study you read, but they all fall between 70 and 80%). Whey protein is also digested quickly and its “net protein utilization” (NPU) is in the low 90%s, which means that 90-something percent of it can actually be used by your body. Egg protein digests much slower than whey and beef and its NPU also falls in the low 90%s.
NPU and digestion speeds are important to know because you want to rely on high-NPU proteins to meet your daily protein requirement, and you want a quick-digesting protein for your post-workout meal and a slow-digesting protein for your final meal before you go to bed.
I could give you charts and tables of the NPU rates of various proteins, but I’m going to just keep it simple. In order to meet your daily protein requirements, here are your choices:
Whole Food Proteins
Lean meats (beef, pork, chicken, and turkey)
Vegetarian sources noted above

In case you’re wondering why I left soy protein off the list of recommended supplements, it’s because it’s just a bad protein source. To start, most soy protein supplements use genetically modified soybeans (which is a very dangerous trend encroaching further and further into the world of agriculture), and studies have shown that too much of it can increase estrogen levels and inhibit your body’s testosterone production (due to a plant estrogen found in soybeans). Just stay away from it.
What is the Best Protein Powder for Building Muscle?
So, the best protein powder for building muscle comes down to the three I just listed: egg, whey, and casein. There are a million different brands and some are marketed with so much hype that it’s like the copywriters were hyperventilating while they were writing.
And in case you’re wondering why I left soy off the “recommended list,” it’s because it’s just a bad protein source. To start, most soy protein supplements use genetically modified soybeans (which is a very dangerous trend encroaching further and further into the world of agriculture), and too much of it can inhibit your body’s testosterone production (due to a plant estrogen found in soybeans). It generally tastes bad too. Just stay away from it.
Now, regarding when to eat slow- or fast-digesting proteins, I recommend eating a fast-digesting protein like whey after working out to quickly spike amino acid levels in your blood and stimulate muscle growth, and eating a slow-digesting protein like egg or casein 30 minutes before going to bed, as research has shown this helps improves recovery.
For the rest of your supplement meals, you can do whey or egg. I like to do egg because too much whey tends to bloat me.
