We’ve provided more details below in our testing notes, but we were very impressed overall.

Our tester, who is a certified personal trainer, states, “This is, without question, one of the best protein powders I’ve had in recent memory. You get the satiety you want from a mixed shake, there aren’t any negative side effects post-consumption, and the flavors are impeccable. I’d recommend this powder to anyone looking to switch up their supplement regimen. It’s a clear staple in my routine now.”

Our Experience Using Transparent Labs 100% Grass-Fed Whey Protein Isolate
Overall, we loved testing out Transparent Labs 100% Grass-Fed Whey Protein Isolate. It’s highly rated for its clean formulation, featuring easily digestible whey isolate from grass-fed cows and all-natural ingredients. As a bonus, it comes in delicious flavors that athletes love and mixes well in various liquids. It’s also third-party tested to ensure quality and transparency.
Ingredients and Formulation
As registered dietitians, Chelsea Rae Bourgeois, M.S., R.D.N., L.D., and I rated this product a 4.5 out of 5 for its formulation. Its protein source is whey protein isolate, a highly digestible protein for those with lactose intolerance or gassiness after taking other protein supplements. (1) Since it’s a whey isolate, it’s virtually lactose-free, making it one of the best protein powders for sensitive stomachs.
Our tester, a certified personal trainer, noted the lack of side effects after trying this product. They state, “I didn’t experience any bloating or stomach rumbles, which was a pleasant surprise as I’ve had other proteins that caused serious GI distress.” Given its lack of gastrointestinal effects, we think it’s a great supplement to take with or without a meal post-workout.
Moreover, the high protein amount in this product is commendable for meeting dietary goals. With 28 grams of protein, including all essential amino acids, it’s enough to meet most athletes’ requirements depending on how much protein is needed. For context, the USDA recommends 0.8 grams of protein per kilogram daily for sedentary individuals. (2) However, athletes who engage in high levels of physical activity and want to build muscle may need up to 1.6 grams per kilogram daily. (3) It also offers a good macronutrient balance with only 1 gram of fat and 1 gram of carbohydrates.
Beyond the nutrients, we also loved the ingredients in Transparent Labs. It’s slightly sweetened with stevia extract, flavored with natural flavors, and contains no artificial flavors, artificial colors, or low-grade filler ingredients that don’t contribute nutritional value. Bourgeois states, “I love that Transparent Labs Whey Protein Isolate is free from artificial sweeteners, food dyes, and preservatives. You get 28 grams of high-quality protein per scoop without unnecessary fluff.”
And last but not least, it comes from 100 percent grass-fed American cows. Studies show that grass-fed whey is higher in beneficial ingredients that support muscle recovery and overall wellness, like immunoglobulins, lactoferrin, omega-3 essential fatty acids, CLA, and antioxidant vitamins A and E. (4)
The only major downside in this product’s formulation is that certain flavors are high in sodium compared to USDA recommendations of up to 2300 milligrams per day. (2) “Some flavors contain up to 370 mg of sodium per scoop, higher than many other protein powders on the market. Those who are watching their sodium intake may not enjoy the amount of sodium per scoop,” Bourgeois adds.
Taste
Our tester, who is a certified personal trainer, gave Transparent Labs Whey Protein a 5 out of 5 for its excellent taste. They state, “I enjoyed the flavor of this protein powder. I got my hands on a limited-edition flavor, Peppermint Hot Chocolate. While there wasn’t as much peppermint as I’d hoped, I was pleased with its mouthfeel and taste. All I needed were some mini marshmallows to complete the scene.” Plus, this product comes in 13 different flavors, so if you don’t find a flavor you like, you have plenty of alternatives.
However, we noticed it contains stevia (a natural sweetener), which can taste bitter to some people who are sensitive to it. Overall, compared to other protein shakes we’ve tried, we felt that the other ingredients masked the bitterness of the stevia pretty well.
Solubility
While other protein powders may not mix well, Transparent Labs received a sparkling 5 out of 5 for solubility. Our tester states, “No issues here. I easily mixed the powder in my shaker cup, and the consistency wasn’t gritty. It’s a very smooth protein powder with no clumps or residue.” So, mix this into water, whole milk, or oat milk in a shaker bottle or a blender for creamy and smooth protein shakes every time.
Price Per Serving
If there’s one area that Transparent Labs Whey Protein Powder doesn’t get stellar ratings on, it’s the price per serving. Chelsea Rae Bourgeois, M.S., R.D.N., L.D., states, “For what you get, it’s a slightly hefty price tag at around $2 per serving.”
However, through the Transparent Labs website and Amazon, you can get discounts for signing up for regular shipments, bringing the price down to $1.80 per serving. Transparent Labs also has some sales throughout the year, so consider signing up for their newsletter to stay in the loop.
Third-Party Testing
Third-party testing is helpful to ensure a product’s purity, quality, potency of ingredients, and presence of harmful components like metals. Transparent Labs excels in this area by offering live testing results from third-party labs on the product page. Transparent Labs Whey Protein Isolate is also Informed Choice and Informed Protein certified.
What to Consider Before Buying Transparent Labs 100% Grass-Fed Whey Protein Isolate
Knowing what to look for when choosing a protein supplement can be challenging, with many options. In a nutshell, Transparent Labs Whey Isolate stands out for its high-quality, natural ingredients and excellent taste and texture, though its premium quality comes with a higher price tag.
Our team tested over 100 supplements, including Transparent Labs 100% Grass-Fed Whey Protein Isolate. We believe these are the top considerations to keep in mind before your purchase.
- Type of Protein: This product contains whey protein isolate. Depending on your dietary preferences, lifestyle, and budget, this protein type may or may not work for you. For example, if you’re vegan, whey is animal-based, so you’ll want to choose a plant-based option from the best vegan protein powders.
- Macronutrient Balance: With 28 grams of protein, 1 gram of carbs, and 1 gram of fat, Transparent Labs is a lean protein supplement that can support various fitness and nutrition goals. However, if you need more carb and fat macros or want to use this supplement as a meal replacement, you may need to bulk up this protein shake with other ingredients that supply those macros (or look for another choice, such as one of the best mass gainer supplements).
- Ingredient Quality: Compared to other whey choices, this product offers no artificial additives, making it ideal for natural enthusiasts. It’s also non-GMO, gluten-free, and third-party tested.
- Taste and Texture: While these factors aren’t related to nutritional value, we think they’re important to address when considering a protein supplement. Transparent Labs mixes well and tastes great.
- Value: If you’re looking for a budget-friendly protein option, this isn’t it. Whey isolates usually cost a little more than standard whey protein powders, and Transparent Labs is no exception at $1.80 to $2.00 per serving.

We’ve compared these supplements to help you make informed choices and determine which product aligns best with your goals and lifestyle. We chose to compare Transparent Labs Whey Isolate to Jacked Factory Authentic ISO and Legion Whey+ because Jacked Factory and Legion are comparable grass-fed whey isolate choices that are also popular among athletes. All three brands claim to offer practical, high-quality, and clean protein powder supplements.
While all three products contain a high amount of protein, we noticed some key differences. Jacked Factory offers the most bang for your buck with an affordable price starting at $1.13 per serving, but it isn’t third-party tested and includes artificial ingredients. Legion Whey+ and Transparent Labs are similar, with the differences being who did their third-party testing, the amount of protein, and the presence of digestive enzymes.
Legion Whey+ is tested by Labdoor, whereas Transparent Labs is tested by Informed Choice and Informed Protein. Transparent Labs has 5 to 6 grams more protein per serving than Legion. Legion contains digestive enzymes to support digestion for those with more sensitive stomachs, while Transparent Labs does not. The flavor choices and solubility are varied among the three brands, which could also be factors to consider.
