As an engineer, David loves technical product comparison and analyzing the data to assess top products.

Let’s break down the best keto protein powders on the market today. Protein powder is a vital addition to your diet if you’re doing gym work, and keto is a great way to get lean and fit. So we’ll review the best of both worlds: protein powder for muscle growth, and keto for getting lean.

Keto is a strict regimen of high-protein and low-carbohydrate diet aimed at launching the body into ketosis. The primary macronutrient for this kind of lifestyle diet is protein. 

While you can create a ketogenic diet from whole food sources alone, protein powder provides an easy, quick, and convenient way to increase your protein intake. But choosing the right one can be challenging. Most powders with low carbohydrates also tend to have ingredients that naturally contain carbs or blends that include carbs.

This article will review some of the best keto protein powder options that won’t kick you out of ketosis. And it incorporates late 2023 and 2024 changes as we wind down the year. We’ll update again in the first few months of 2024 as more changes enter the pipeline in the new year.

1. Crazy Nutrition 100% Tri-Protein

Tri-Protein Powder Reviews100% Tri-Protein by Crazy Nutrition is a simple, delicious formula crafted using premium ingredients for athletic performance. It combines the power of protein and digestive enzymes to help you lose weight and develop muscles. And it’s keto-friendly to keep you in ketosis on your weight loss train!

The formula contains six natural non-GMO proteins that get digested in three phases. The systematic breakdown helps your body maximize nutrient absorption, producing optimal energy and strength. This “all-in-one” powder also suppresses appetite, fighting those sugar cravings.

100% Tri-Protein is the perfect keto-friendly shake worth adding to your weightlifting arsenal. And even if you’re not much into lifting, this protein powder is ideal for anyone following a keto-friendly lifestyle.

And in late 2023 and moving into 2024 Tri-Protein received a very strong endorsement from Men’s Fitness. That is a powerhouse endorsement from a very respected brand, and those are not handed out lightly. So that says a lot for this protein powder formula, and the path that it has been on the last two years. This endorsement is likely related to their release of Formula 2.0.

Unlike other powders, this one tastes great and now comes in four flavors. Two of these flavors are new as of late 2023 and entering 2024). They include:

  • Chocolate
  • Vanilla
  • Strawberry (Limited Edition)
  • Banana (Limited Edition)

Brand Overview

Crazy Nutrition is a premium health and fitness brand that offers top-quality bodybuilding supplements. The company started in 2016 as part of Wolfson Brands Limited (UK-based).

While the brand is relatively new, its parent company (Wolfson Brands Limited) is a big name in the supplement industry, having started in 2005. The company creates superior products from well-researched ingredients, ensuring athletes and fitness enthusiasts get the best they need.

Crazy Nutrition 100% Tri Protein Review

Tri-Protein Powder BenefitsA keto-friendly shake provides sufficient protein to prevent muscle damage as the body enters ketosis. And if it can give this micronutrient longer, it would be even better for your intense training. 100% Tri-Protein from Crazy Nutrition provides just that and more.

First, it combines four (4) proteins that trigger a systematic digestive process (this was a change in late 2023). These proteins include:

  • Whey protein isolate
  • Milk protein concentrate
  • Whey protein concentrate
  • Micellar Casein

Whey protein isolate comes from milk and is a fast-digesting protein. It helps boost muscle strength, reduces hunger, and regulates bowel movements. It’s a pure protein without lactose, fats, or excess sugars. Additionally, it has amino acids for quicker muscle recovery.

The “Tri” in Tri-Protein

Tri-Protein Powder 3-phase AbsorptionThe “Tri” in Tri-Protein describes the time released phases of the six proteins. There are three timed releases, so the protein feeds into your system over 24 hours for max effect. This is a powerhouse effect, as the 6 high-powered proteins are released in three phases.

Milk protein concentrate comes from skim milk and contains essential nutrients. It stimulates protein synthesis, improves absorption and supply of nutrients, and promotes satiety.

Whey Protein Concentrate is a fast-absorbing protein that boosts the absorption of nutrients. It keeps your stomach full and aids in building and strengthening muscles.

Hydrolyzed whey is the fastest-digesting protein that helps reduce muscle pains and soreness. It also aids in weight management and boosts muscle growth.

Micellar casein is a slow-digesting protein that helps maintain lean muscle mass during rest periods. It can supply your body with enough proteins for 12 hours.

Calcium caseinate is another slow-digesting protein derived from milk casein. It contains amino acids that are essential for muscle recovery and maintenance.

Transparent Labs Whey Protein Isolate Review

This protein shake utilizes whey protein isolate, the purest form of whey.
