Regardless of your training and aesthetic goals, protein offers many health benefits – it helps you build and repair muscle after workouts.

Taste and Solubility

It’s hard to find a great tasting protein, but this whey protein powder has an overall 4.7-star rating according to the Jacked Factory website, based on 132 reviews from consumers who have tried it. Many of the consumer reviews note that it is delicious.

Amanda Capritto, CPT, CES, CNC, CF-L1, CSNC, tested this product and noted it fares pretty well with both water and milk but would recommend mixing with milk: “I used the vanilla Jacked Factory Authentic ISO with both water and milk. I would recommend using it with milk because the taste and texture were better, but it’s still pretty good with just water alone.” It scores a 4 out of 5.

As far as solubility, Capritto noted that it’s not perfectly soluble, but does a decent enough job to drink it without issues: “Even in a shaker cup, this mixes well. You’ll still have a little bit of floaters, so it doesn’t mix perfectly if you are looking to just put it in a shaker cup and have it at the gym. But it’s still mixed well enough to drink.” As a result, we scored it a 4 out of 5.


Jacked Factory Authentic ISO Grass Fed Whey Protein Isolate scored 4.5 out of 5 overall based on our testing. It has simple ingredients with 25 grams of protein and is low-carb. The only downside of the formulation is that it contains stevia extract, which can often give a bitter aftertaste to some individuals. It also contains sucralose, an artificial sweetener that some athletes may prefer to avoid or limit.

The formula has five simple ingredients: grass-fed whey protein isolate, natural and artificial flavors, Himalayan rock salt, and natural and artificial sweeteners (sucralose, stevia extract).

The primary ingredient is 100% grass-fed whey isolate. Whey isolate undergoes further processing compared to standard whey protein. This process removes more fats, carbohydrates, and lactose – and, therefore, “isolates” the whey. This results in a product with a higher whey protein concentrate (usually around 90% or higher) and minimal lactose content. Whey isolate tends to be more nutrient-dense than whey protein, making it a popular choice among athletes with lactose intolerance or those seeking higher protein content per serving.

Unlike some other options, Jacked Factory Authentic Whey does not contain unnecessary fillers and additives. It’s also free of soy, lactose, and dyes. Due to its clean ingredients, many consumer reviews note that it does not cause bloating like other protein powders.

Benefits of Taking Jacked Factory Authentic ISO

Protein is a vital macronutrient composed of amino acids including essential amino acids. These building blocks of protein play an essential role in muscle building and repairing, producing enzymes and hormones, hormone synthesis, and supporting a healthy immune system.

While an adequate protein intake is helpful for general health and wellness, taking a protein supplement is particularly important for athletes looking to build and maintain lean muscle mass, engaging in regular intense physical activity, bulking or seeking muscle growth, or aiming for best protein powder for weight loss. (1) Incorporating protein into your diet also helps promote a feeling of fullness and satiety. (2)

Remember that supplements such as protein powders and protein bars should supplement, not replace a balanced diet. When possible, athletes should aim to meet their protein intake from various protein sources as they provide a wider range of essential nutrients such as dietary fiber, vitamins, and minerals, that are beneficial to meeting your nutrient needs.

What to Consider Before Buying the Jacked Factory Authentic ISO

When considering what protein powder to choose, it’s important to consider the flavors available, price per serving, and whether the product is third-party tested.

Your protein needs may also vary depending on your activity level, gender, dietary preferences, and allergies. For individualized needs, you may want to check out the specific roundups of protein powders for men.

For those who like to bake, cook, or add protein to their favorite foods like Greek yogurt or oatmeal, the unflavored version is an excellent choice. Other flavors blend easily into smoothies or mix with milk or dairy alternatives for a decadent, post-workout protein shake.

Price Per Serving

Price per serving is one of the many factors people consider when choosing a protein powder. Jacked Factory Authentic Whey costs $39.99 for a 30-serving tub. This means that the price per serving is $1.33. Each serving contains 25 grams of 100% grass-fed, whey protein isolate.

Jacked Factory is more expensive than conventional whey protein, but this dietary supplement is a premium product since it’s whey isolate and 100% grass-fed.

Third-Party Testing
