Best Protein Powders at Costco
Optimum Nutrition Gold Standard Whey
| Nutrition Category | Quantity per serving (g) |
| Calories | 113 |
| Carbohydrates | 1.3 |
| Protein | 24 |
| Fat | 1.3 |
One of the best protein powders at Costco is this one by Optimum Nutrition. Optimum nutrition has one of the best brands of protein powders across the globe – they make a wide range of supplements, and it’s known that their whey powder is among the best. We love that this supplement is entirely whey protein, rather than cutting the whey with some cheaper alternatives, which other brands often do. This is one of the biggest selling supplements from Costco, and it’s easy to see why.
Forzagen Vegan Protein Powder
| Nutrition Category | Quantity per serving (g) |
| Calories | 130 |
| Carbohydrates | 7 |
| Protein | 20 |
| Fat | 3 |
If you need a good amount of protein from Costco, don’t forget to try this Fozagen Vegan Protein Powder. Something that we’re really impressed with in this protein powder is the protein-to-calorie ratio. At only 130 calories, it packs eighteen amino acids and twenty grams of protein into a single serving! This is absolutely stunning, and we’re really impressed that it’s gluten-free too. Some protein powders can be quite hard on the digestive system, but this option is a little easier, which may be great for your regime. Forzagen is a fairly new company with little information out there about this, but this product is truly impressive – of the 350 reviews on its Amazon page, over half are five stars.
Muscle Pharm Combat Protein Powder
| Nutrition Category | Quantity per serving (g) |
| Calories | 140 |
| Carbohydrates | 4 |
| Protein | 24 |
| Fat | 1.5 |
Another popular protein powder at Costco is their Muscle Pharm Combat Protein Powder. This is a great supplement if you’re looking for an option that’s really friendly to your wallet while also being low in carbs. While it’s not too low calorie, this US-based brand has been sure to create this protein powder such that it’s got plenty of protein in it for your gym-going needs. 24g is a respectable portion of protein for a serving, plus it’s super low in carbs, fat, and sugar. This means that this protein powder could be a great option for people aiming for lean muscle growth.
Quest Protein Powder
| Nutrition Category | Quantity per serving (g) |
| Calories | 110 |
| Carbohydrates | 2 |
| Protein | 24 |
| Fat | 1.5 |
The next protein powder on the list is Quest Protein Powder. Quest is more known for its protein bars than for its protein shakes. This means that you might be a little surprised to see this brand on our list, but the numbers don’t lie – this is a great low carb, low sugar, gluten-free option for gym-goers. It’s worth considering that for the sweetening process, some amount of stevia and sucralose are used. This isn’t a bad thing inherently, but it may be worth considering if you’re concerned about artificial sweeteners in your diet.
Premier Protein Powder
| Nutrition Category | Quantity per serving (g) |
| Calories | 150 |
| Carbohydrates | 3-4 |
| Protein | 30 |
| Fat | 1.4 |
If you are looking for a strong protein contender from Costco, go for the Premier Protein Powder. The protein supplements up for grabs from the Premier brand can be bought as straight shakes or as a powder that you can add some of your own liquid to. The shake itself is one of the best protein shakes that Costco sells – there are over 16,000 five-star reviews. With that in mind, it’s a given that this powder is a great one. We’re really impressed that a single portion offers thirty grams of protein, that’s an awful lot for one portion!
Body Fortress Protein Powder
| Nutrition Category | Quantity per serving (g) |
| Calories | 150 |
| Carbohydrates | 8 |
| Protein | 30 |
| Fat | 5 |
If you want to add 30 grams of protein to your diet, grab a scoop or two of this delicious protein powder by Body Fortress. Body fortress is a company based in New York that has been doing exceptionally well in recent years due to the fact that they have protein powders that isolate different types of supplements on top of the protein itself. For example, they sell fat burner protein powder, as well as straight whey protein. This is one of the healthiest protein powders on this list, we would say, because of the sheer amount of protein in it – thirty grams is an awful lot! On the flip side, though, we’re not impressed with the volume of sodium in this powder – since a serving is fifty grams of powder, there’s a lot of sodium and cholesterol in each portion, which can have a negative effect on the long run.
Orgain Protein Powder
| Nutrition Category | Quantity per serving (g) |
| Calories | 150 |
| Carbohydrates | 8 |
| Protein | 21 |
| Fat | 4 |
Another great protein powder from Costco is Orgain Protein Powder. This is a perfect protein powder due to the fact that it’s entirely vegan – all the protein in it is derived from plant-based sources! While this does mean that it’s not truly a whey powder, you are encouraged to take it as such and can achieve the exact same input from this powder. The protein is a blend of pea, brown rice, chia, and hemp – this provides all twenty essential amino acids!
Purely Inspired Organic Protein Powder
| Nutrition Category | Quantity per serving (g) |
| Calories | 130 |
| Carbohydrates | 2 |
| Protein | 20 |
| Fat | 2 |
Next on the list is this Purely Inspired Organic Protein Powder. Another entirely vegan and entirely organic protein powder, we love that this powder is such a good add-on for what you might be drinking anyway. A scoop, or even a half-scoop, of this powder, would make for a great addition to a green smoothie, leading to a nutritionally boosted smoothie to boost your gains.
SB Organics Vegan Protein Powder
| Nutrition Category | Quantity per serving (g) |
| Calories | 170 |
| Carbohydrates | 8 |
| Protein | 21 |
| Fat | 6 |
Last on this list of exceptional protein powders is SB Organics Vegan Protein Powder. This is a great protein powder, and the facet of it that we’re most impressed by is the fact that it contains probiotics, enzymes, and amino acids. This, arguably, makes it the most healthy on this list since it will easily boost your digestive health and allow you to be confident in your gut health. One downside is that this protein powder has 170 calories per serving, which isn’t too great for lean muscle growth. However, that’s something that only some people want, so it may not be a drawback that’s important to you.
