KLEAN ISOLATE

Expert Take
Reviewed by Garett Reid, MSc, CSCS, CISSN
Strength coach & sports nutrition specialist · · About the author

KLEAN PRE-WORKOUT

  • Klean Athlete Klean Pre-Workout combines 300 mg of dietary nitrates from beetroot extract with 75 mg of organic caffeine to support endurance, blood flow, and alertness. The relatively low caffeine content makes it suitable for individuals who prefer a milder stimulant effect. Its NSF Certified for Sport designation is another advantage for competitive athletes.

However, 300 mg of nitrates is slightly below the 400โ€“800 mg range commonly recommended for endurance performance, while 75 mg of caffeine is below typical evidence-based ergogenic doses. Overall, it's a reasonable option for light pre-workout stimulation, but individuals seeking stronger performance benefits may find the formula underdosed.

KLEAN ISOLATE

  • Klean Athlete Klean Isolate provides 20 grams of whey protein isolate per serving, including approximately 2.08 grams of leucine, to support muscle protein synthesis and exercise recovery. Its simple, unflavored formula contains just whey protein isolate and sunflower lecithin, making it convenient for mixing into shakes, smoothies, or other foods.

Its NSF Certified for Sport designation is an advantage for competitive athletes. However, 20 grams of protein is relatively modest compared with some competing whey isolates, and individuals with higher protein requirements may prefer a larger serving. Overall, it's a straightforward, low-carbohydrate protein supplement with minimal additives.

KLEAN CREATINE

  • Klean Athlete Klean Creatine provides 5 grams of creatine monohydrate per serving, an effective daily dose supported by extensive research. Creatine is particularly beneficial for improving strength, power, repeated high-intensity exercise performance, and lean mass gains when combined with resistance training. Unlike many performance supplements, its benefits are well established across numerous clinical studies.

Its NSF Certified for Sport designation is a major advantage for competitive athletes concerned about banned substances. The single-ingredient formula also eliminates unnecessary additives. However, creatine requires consistent daily supplementation, and some users may experience temporary water-weight gain. Overall, it's an excellent choice for strength and performance.
