I Tried True Nutrition Whey Protein Isolate Cold-Filtration Powder: Here’s My Honest Review (2025)

True Nutrition Whey Protein Isolate Cold-Filtration powder is minimally processed and contains artificial sweeteners or flavors, according to the company. The unflavored option contains only two ingredients: Whey protein isolate and lecithin (soy).

Whey protein isolate is made by separating and isolating protein from whey, a nutrition-packed byproduct of milk formed in the process of making cheese curds. Isolating the proteins in whey specifically helps retain a higher protein content. True Nutrition also adds the step of cold-filtration to their isolation process, which is typically performed at a temperature lower than 68 degrees Fahrenheit to preserve nutritional integrity, increase digestibility and improve taste.

True Nutrition’s Whey Protein Isolate Cold-Filtration powder in the chocolate brownie flavor contains 27 grams of protein per serving, a higher amount than some competitors on the market. However, it’s worth noting that the amount of protein per serving varies among flavors, with the brand’s unflavored option offering the most protein at 30 grams per serving.

This protein powder comes in 33 flavor options, including chocolate fudge brownie, french vanilla, cookies and cream, cafe mocha, chai latte, strawberry, toasted coconut, banana, fruit punch and orange cream. However, flavored options may contain additional ingredients, such as plant-based sweeteners like stevia, non-GMO rice powder, gum acacia and natural or artificial flavoring and coloring.

I was drawn to True Nutrition Whey Protein Isolate Cold-Filtration powder because I wanted to ensure that I was getting enough daily protein. I love chocolate, so I bypassed the unflavored option and ordered the chocolate fudge brownie flavor. Ordering was simple through the company website, and product delivery took about one week.

The label directions suggest mixing one scoop (a scoop is included in the product packaging) of protein powder with one cup of water, milk or juice. I chose to compare all three combinations.

I first mixed the protein powder with 2% milk in a blender. The flavor was good and not as chocolatey as some protein shakes I’ve tried. I wasn’t that crazy about this ingredient combination, mainly because after drinking the beverage, I got a slight stomach ache. I don’t know if that was caused by the protein powder, the milk or some unrelated fluke, but the stomach discomfort tainted my experience with the product.

The next day I mixed water and a small amount of ice with the protein powder in a blender until the beverage was smooth. I blended the mixture and found the consistency smoother than the milk and powder blend. I also liked the chocolate taste better.

For the juice, I thought about different chocolate combinations I like, deciding to mix the protein powder with orange juice then black cherry juice in a blender. While the orange juice combination was a tasty option I’d recommend, I was blown away by the deliciousness of the black cherry juice blend.

Of all the combinations I tested, my top picks were black cherry juice, water, orange juice and milk, in that order.

True Nutrition Whey Protein Isolate Cold-Filtration Powder: What I Liked

One of my favorite things about True Nutrition Whey Protein Isolate Cold-Filtration powder is the generous 27 grams of protein per serving.

True Nutrition Whey Protein Isolate Cold-Filtration Powder: What I Didn’t Like

I always like to review a supplement’s third-party lab test results for each batch. However, I wasn’t able to find lab results for the Whey Protein Isolate Cold-Filtration product on True Nutrition’s website. I had to search the frequently asked questions (FAQs) section, only to find that I’d need to email the company to see the lab report.

I emailed my request and received the lab report testing for heavy metals the next day. The product passed on all heavy metal levels. Still, when I’m ready to order, I don’t like my momentum stalled while I wait for important information I need to make an informed decision.

Sarah Herrington, a nutritionist at Brio-Medical, an alternative medical treatment center in Scottsdale, Arizona likes the minimal number of ingredients in True Nutrition’s Whey Protein Isolate Cold-Filtration powder. What’s more, she appreciates that the company does third-party testing and that the product is whey based.

“Whey protein isolate is an excellent source of protein,” says Herrington. “It is easily digestible, as well as lower in lactose than other milk-based proteins, such as casein or other whey blends.”

However, given the product’s inclusion of soy, which Herrington notes is typically used in small amounts to enhance flavor and mixability, she doesn’t recommend the powder for all customers.

“It’s probably not necessary in this blend and makes this now a product that those with an allergy or sensitivity to soy cannot consume,” says Herrington, who also suggests people with sensitivities to lactose or dairy products, or who have other gastrointestinal issues avoid using the powder as it may cause digestive upset.

“This protein is great for anyone on a low-sugar or low-carbohydrate diet, or those looking to augment their current diet with a source of protein,” she says.
