The Perfect Keto Bar is a keto-friendly collagen-based protein bar that was formulated to provide a snack to ketogenic dieters that doesn’t spike blood sugar. It’s available in four flavors: Almond Butter Brownie, Chocolate Chip Cookie Dough, Salted Caramel, and Lemon Poppy Seed.

About the Company

Perfect Keto is a company with a goal of making keto easier. Founder Dr. Anthony Gustin created Perfect Keto because he wanted people following keto to have research-backed, trustworthy products. Perfect Keto emphasizes the use of whole-food ingredients that won’t spike blood sugar and will keep you on track with your ketogenic lifestyle. 

How It Tastes

The Perfect Keto Bar comes in four flavors: Almond Butter Brownie, Chocolate Chip Cookie Dough, Salted Caramel, and Lemon Poppy Seed, and the tastes are spot on. Their flavors match their descriptions: the salted caramel bar is sweet, so if sweetness isn’t your thing, try almond butter brownie or lemon poppy seed. While each bar has a slightly different texture, the general texture is soft, crumbly, and chunky.


The Perfect Keto Bar contains 11 grams of collagen protein, a protein that we produce less of as we age. Collagen protein can improve skin, gut, and joint health. Perfect Keto didn’t sacrifice quality here either; they use grass-fed collagen. But there’s more to love. Check out their ingredients list, which features a small amount of quality ingredients:

Ingredient List: 

Organic almond butter, soluble tapioca fiber, grass-fed collagen, cacao butter, sunflower lecithin, natural flavors, MCT oil powder (MCT oil, acacia fiber), sea salt, stevia.

Perfect Keto did a great job with the quality of ingredients. Many companies producing bars sacrifice quality by using peanut butter, which is cheap and proinflammatory, but the Perfect Keto Bar uses organic almond butter. A much better choice.

The bar uses soluble tapioca fiber to help bind the ingredients together into a bar. This is important because most binding agents used to make bars contain carbohydrates such as honey or dates. Soluble tapioca fiber is a low-glycemic fiber, meaning it’s keto-friendly and shouldn’t have a huge impact on glucose or ketone levels. We put the bar to the Keto-Mojo test to be sure.

How It Affects Blood Sugar and Ketones

While ingredients are important factors in evaluating a product, it’s also important to determine the impact these ingredients have on blood sugar and ketones when they are combined into one single food. To test this, we opted to eat the Almond Butter Brownie flavored Perfect Keto Bar in a fasted state and tested blood levels using a Keto-Mojo meter. Below are the results. As you can see, the Perfect Keto Bar had virtually no impact on blood glucose and ketone levels.


The Final Word

The Perfect Keto Bar passes our test. Its emphasis on quality ingredients allows for good flavor without spiking our blood glucose or impacting our ketones. It’s a great on-the-go snack and is also ideal before a workout or anytime you have a sweet tooth. Plus, it provides enough nutritional punch that it’s helpful between meals or even to replace breakfast.
