Whey protein isolate is the gold standard of protein powders, and it\u2019s the only one I take besides collagen, but it\u2019s not the only one out there. There are reasons for branching out beyond whey into other types of protein powder. Maybe you\u2019d like some variety once in awhile. Maybe you\u2019re just curious about what else is out there, or perhaps you don\u2019t want any animal protein at all. Whatever the reason, I figured I\u2019d give you some info on some of the more popular types of protein powder, including whether or not they contribute meaningfully to our intake of essential amino acids.<\/p>\n
Before we begin, let\u2019s talk about how we can measure a protein\u2019s usability.<\/p>\n
The BV (biological value) is one way to measure a protein\u2019s \u201cusability.\u201d Biological value testing measures the amount of nitrogen that appears in the urine and feces after eating it to determine how much was retained and utilized by the body. If very little nitrogen appears in the toilet after eating a given protein, that protein has a high BV. If a good amount appears in the toilet, that protein has a lower BV.<\/p>\n
The higher the BV, the greater the proportion of available protein that can be synthesized by the body\u2019s cells. Higher BVs usually indicate a greater amount of essential amino acids\u2014those amino acids that the body cannot synthesize or convert on its own and must instead obtain from the diet\u2014but it doesn\u2019t measure them specifically.<\/p>\n
Note, though, that biological value does not refer to the amount of protein in the powder; it only refers to the usability of the protein in the powder. A particular powder might be 60% protein, and the biological value would tell you exactly how much of that 60% is usable by the body. Different powders have different protein contents. Hemp protein, for example, is often about 50% protein, but it varies by the manufacturer. A quick glance at the nutrition facts should clue you in.<\/p>\n
There\u2019s also the protein digestibility-corrected amino acid score (PDCAAS), which is the method by which the World Health Organization and FDA evaluate protein value. It\u2019s a newer model, and it\u2019s based on the amino acid requirements of humans, specifically children, as well as digestibility and absorption. To determine the PDCAAS, they measure fecal nitrogen and track the amount of essential amino acids in each protein powder. Most promotional materials use the BV, but the PDCAAS is more accurate for what we care about. Whey protein isolate (both isolate and concentrate) has an optimum PDCAAS of 1.<\/p>\n
A newer method of quantifying protein quality is the DIAAS, or Digestible Indispensable Amino Acid Score. This is similar to PDCAAS, but instead of measuring nitrogen in the feces, it measures nitrogen in the ileum after it has left the small intestine and before it descends into the large intestine. This is more accurate than measuring fecal protein, because fecal protein may be lower due to protein metabolism by gut bacteria. Measuring it in the ileum reflects only what the body has absorbed.<\/p>\n
Whichever method you use to quantity protein quality\u2014BV, PDCAAS, or DIAAS\u2014animal proteins like whey outperform plant proteins. So as a good general guideline, it\u2019s safe to assume that animal-baed protein powders are going to be higher quality than plant-based protein powders. That said, let\u2019s get into the specific powders ranked according to overall quality and usability.<\/p>\n
The gold standard against which everything else is compared. Whey defeats all. It\u2019s rich in essential amino acids and has a host of benefits for immunity, muscle-building, performance, cognitive function, and overall robustness. Read more about whey\u00a0for a discussion of its benefits.<\/p>\n
Egg white protein powder is another highly bioavailable protein choice. In fact, it\u2019s so bioavailable that it represents the BV against which all others are compared (that\u2019s why whey can have a BV exceeding 100). All the amino acids are represented. If you\u2019re concerned about oxidized cholesterol, stay away from whole egg protein powder. You may be able to get a hold of a minimally processed whole egg powder with very little oxidation, but you\u2019ll probably end up spending a ton of money. Just eat actual eggs or stick with egg white powder instead.<\/p>\n
Derived from that other fraction of milk protein, casein protein powder doesn\u2019t absorb as quickly as whey. It\u2019s a complete protein with the full range of amino acids (including ample amounts of glutamine, which transports nitrogen to tissue), just like whey, but it may be problematic for people with casein intolerance. Those with dairy allergies should probably avoid it. Bodybuilders swear by casein; they dig it for the slow absorption rate and tend to take it before bedtime. One (industry funded) study found that casein was inferior to whey protein in terms of body composition and muscular strength outcomes, so I wouldn\u2019t replace whey with casein just yet. There may be some benefit to taking both, since both casein and whey are a package deal in nature. Milk is certainly a popular post-workout recovery drink, and it contains both casein and whey.<\/p>\n
Soy protein is actually one of the more complete plant proteins, and it can definitely fill in some nutritional gaps for people who don\u2019t eat any animal products at all, but there are downsides. One big one is that soy protein supplementation has been shown to depress testosterone production in men.<\/p>\n
Potato protein is my favorite plant protein of all. The protein powder isn\u2019t very economical or widely available, but potatoes have almost complete protein, about as good as soy without the negative effects on testosterone. If this becomes more common I\u2019d recommend it to any vegan dieter.<\/p>\n
30 grams of potato protein compares favorably to 30 grams of milk protein in resistance trained individuals looking to gain strength and size. Note, though, that 20 grams of milk protein will be more effective than 20 grams of potato protein. The lower the value of the protein, the more absolute protein you need to eat to get the same effect.<\/p>\n
I\u2019m generally down on vegetarian protein powders. In my experience, they just don\u2019t work as well as the animal-based ones. We\u2019re not meant to get all our protein from vegetable sources, and our absorption of vegetable-based protein isn\u2019t as efficient, so you have to consume far more pea protein powder just to get enough\u2014and this stuff can get pretty pricey. Furthermore, pea protein powder tends to be lower in protein by weight than animal-based protein powders. No protein powder is perfectly Primal, but pea protein powder is even less so. If egg and milk protein powders are off limits for whatever reason, though, give pea protein a shot.<\/p>\n
Compared to whey\u2019s huge effect, pea protein has an intermediate effect on post-workout muscle damage. And that was taking pea protein 3x a day. So it\u2019s better than nothing, but still not as good as whey.<\/p>\n
If you refuse to use whey protein, egg protein, or casein, you have the option of eating pure wheat gluten. Of course, gluten activates zonulin, which regulates intestinal permeability and increases leaky gut in everyone who eats it.<\/p>\n
Rice protein powder is created by isolating the protein from the brown rice grain. Rice is already one of the least offensive grains out there, so a smattering of rice-based amino acids will work okay. You\u2019re not going to absorb or digest the rice protein with as much ease as with animal-based protein, but that\u2019s fine.<\/p>\n
There is a study where rice protein supplementation had similar effects on muscle strength and gains as whey supplementation, but it took a heroic dose to get there: almost 50 grams. You could get the same effect on muscle protein synthesis with just 20 grams of whey isolate or 30 grams of potato protein.<\/p>\n
Hemp is another option for vegetarians (or nutrition explorers). Like the other vegetarian protein powders, hemp is quite a bit lower in protein content than the animal protein-based powders (or even other vegetarian powders). It\u2019s generally loaded with tons of fiber and a bit more fat than other powders, but fiber-free versions do exist. Again, not my first choice, and it\u2019s fairly expensive, but hemp powder does taste relatively good and usually comes with some minerals like magnesium.<\/p>\n
However, there are no published studies on hemp protein and muscle protein synthesis. The closest I could find was one where hemp protein lowered blood glucose compared to eating an equivalent dosage of carbs, which should come as no surprise.<\/p>\n
When selecting which protein powder is right for you it\u2019s important to keep these three elements in mind.<\/p>\n
Whey protein powder is proven to be the most effective. Protein powder in general can help athletes recover from training, and it doesn\u2019t have to be dairy-based, if you\u2019re sensitive. There\u2019s nothing wrong with dabbling (or even throwing yourself into) in alternative protein powders, and in the case of casein and egg whites, you might even see added benefits by incorporating them into your whey regimen.<\/p>\n
But that doesn\u2019t mean you need<\/em> protein powder.<\/p>\n Take your time and evaluate your diet. You may find that you don\u2019t need powder supplements. I certainly don\u2019t need any myself, but that doesn\u2019t mean I don\u2019t enjoy a big whey shake after an intense workout session from time to time, just for the anabolic effects as well as the convenience and taste. If you\u2019re not getting enough protein, or you can\u2019t find the time to cook every single meal, try some protein powder. Otherwise, eat a steak.<\/p>\n
