Jacked Factory is a supplement brand that offers a variety of nutrition products, including protein powders, pre-workouts, amino acids, creatine and protein bars.

Jacked Factory makes several protein products, including whey protein powder, casein and vegan protein powder. They currently offer two whey protein products; Authentic Whey Premium Protein Powder and Authentic Iso Grass-Fed Whey Protein Powder. There are a few differences between these products. Jacked Factory Authentic Whey Premium Protein Powder is made with a blend of whey protein isolate and whey protein concentrate, while Jacked Factory Authentic Iso Whey Protein is made with whey protein isolate only.

Whey protein isolate contains up to 90 percent protein, and is low in fat and lactose. Whey protein concentrate contains between 35-80 percent protein, and is higher in fat and lactose than whey protein isolate. Jacked Factory Authentic Whey Premium Protein Powder contains 24 grams of protein per serving—one gram less than the Authentic Iso Whey Protein product—and contains more ingredients than Jacked Factory Authentic Iso Whey Protein, including additives like xantham gum and guar gum, as well as the anti-caking agent silicone dioxide.

Jacked Factory recommends mixing their Authentic Iso Whey Protein with eight to 12 ounces of water and mixing it until you reach a desired consistency. This product can also be blended with milk or non-dairy milk and ice to create a protein shake. You can enjoy Jacked Factory Authentic Iso Whey Protein any time of day, but whey protein has been shown to be effective for promoting muscle growth when taken before or after a workout.

At the time of writing, Jacked Factory Authentic Iso Whey Protein has 101 reviews and a 4.7/5-star rating on the Jacked Factory website, and 420 reviews and a 4.4/5-star rating on Amazon. Most customers love the taste and texture of this protein powder and report that the powder mixes easily into any liquid. However, some customers report that the taste is too sweet for their liking, which isn’t surprising based on the fact that sucralose and stevia are much sweeter than regular table sugar. Overall, Jacked Factory Authentic Iso Whey Protein seems to be well-received by customers.

What we love:

Whey protein isolate is high in protein
Made with whey from grass-fed cows
Relatively affordable
Comes in dessert-inspired flavors
Zero grams of added sugar

What to consider:

Contains sucralose, an artificial sweetener that many people prefer to avoid
Not third-party tested for quality and purity

Quality of Ingredients

Jacked Factory Authentic Iso Whey Protein contains just five ingredients: grass-fed whey protein isolate, natural and artificial flavors, Himalayan rock salt, sucralose and stevia.

Each 30.1-gram scoop provides 25 grams of grass-fed whey protein along with just one gram of sugar and less than one gram of fat. The term “grass-fed” is used to describe meat and dairy products from cows that eat grass. Cows that are grass-fed or pasture-raised often have a much better quality of life compared with animals raised on conventional dairy farms. Additionally, whey from grass-fed cows "is reported to have a higher fat and protein content with improved nutritional status." Although Jacked Factory does use whey from grass-fed cows in their Authentic Iso Whey Protein, they don’t go into too much detail about where they source their whey and what farms they work with.

As opposed to many flavored proteins on the market, Jacked Factory Authentic Iso Whey Protein only contains one gram of sugar. It’s sweetened with a blend of stevia and sucralose, the latter of which has been linked with a few health concerns. For example, regular use of artificial sweeteners like sucralose is associated with an increased risk of certain cancers. What’s more, artificial sweeteners have been shown to negatively impact gut bacteria and may promote a pro-inflammatory environment in the gut.

Unfortunately, Jacked Factory doesn’t currently offer unsweetened whey protein powder, and all of their whey protein flavors contain either sucralose or acesulfame potassium (ACE-K), another artificial sweetener that’s been linked to negative health outcomes.

Additionally, although the company strives to create high-quality products, Jacked Factory supplements are not third-party tested for quality and purity.

Who Jacked Factory Iso Whey Protein Is Best For

Jacked Factory Authentic Iso Whey Protein is a good choice for people who like sweeter-tasting, flavored protein powders. In addition to five dessert-inspired flavors, this product is offered in an Unflavored version.

Jacked Factory Authentic Iso Whey Protein is a rich source of highly absorbable protein, which can help athletes and non-athletes alike reach their body composition goals by supporting muscle growth. What’s more, people who’d like to lose body fat could benefit from adding a whey protein supplement to their diet. Research shows that increasing overall protein intake is an effective way to reduce overall calorie intake and support fat loss.

It’s also a good choice for people who struggle to meet their protein needs, like older adults with low dietary protein intake.

Who Jacked Factory Whey Protein Isolate Is NOT Best For

Jacked Factory Authentic Iso Whey Protein isn’t a good fit for people who avoid eating dairy-derived products or who would prefer a plant-based protein alternative.

People who are allergic to milk should also avoid whey protein, but people with lactose intolerance can safely use whey protein isolate because it’s so low in lactose. That said, those who are exceptionally sensitive to lactose may want to steer clear of all whey protein products.

Also, this supplement isn’t third-party tested, so it’s not a good choice for professional athletes or people concerned about contaminants like heavy metals and banned substances in sports.

Jacked Factory Whey Protein FAQs

Does whey protein build muscle faster than other forms of protein?

Studies show that supplementing with whey protein powder is an effective way to build muscle mass. However, it doesn’t seem to be significantly more effective for building muscle compared to other protein sources, like pea protein.

Although protein supplements can be helpful when it comes to building and maintaining muscle mass, it’s most important to focus on your protein intake as a whole to ensure you’re eating enough protein every day.

Is it O.K. to drink whey protein on an empty stomach?

Yes, it’s perfectly fine to drink whey protein on an empty stomach. Some people prefer to drink a whey protein shake before or after their workout on an empty stomach.

What happens if you drink protein shakes without working out?

Protein shakes aren’t just for people who work out—they can be a convenient way to increase your protein intake, which is especially important for those who don’t get enough of this macronutrient in their diet. Some people like to use protein shakes and smoothies made with whey protein as a filling snack or light meal when they’re short on time. Just like any food, your body breaks down protein shakes and uses the nutrients for energy and other important bodily processes.

How long does it take to see results from whey protein?

This depends on many factors, such as your overall diet, activity levels, age and fitness goals. Based on research findings, when combined with regular workouts, you may see changes in your muscle mass and strength after eight to twelve weeks of resistance training and supplementing with whey protein.

Does the FDA approve whey protein?

The FDA doesn’t pre-approve dietary supplements before they're sold online or on store shelves, but it does regulate dietary supplement ingredients and finished products (after they're available to buy). Since the FDA doesn't pre-approve supplements, it's important to look for supplements that have been third-party tested for purity and quality.

Takeaway: Is Jacked Factory Whey Protein Worth It?

Jacked Factory Authentic Iso Whey Protein is a good choice for people looking for an affordable and tasty protein supplement. Customers seem to like the taste and price point of Jacked Factory Authentic Iso Whey Protein, which is why Jacked Factory has built a loyal customer following.

That said, this product does contain small amounts of artificial flavors and sweeteners, which some people prefer to avoid. Also, Jacked Factory ISO whey isn’t third-party tested, so it may not be the best choice for athletes concerned with contaminants like heavy metals and banned substances in sports. And while it's not fit for vegans, it's an easily digestible option for those who prefer whey protein and even those with lactose intolerance.
