The Promise

High‑purity whey isolate — NSF certified

Provides 20 grams of whey protein isolate in each scoop and carries NSF Certified for Sport® testing.

Protein dose you can count on

Each serving supplies 20 g of whey protein isolate to support daily amino acid needs.*

Tested for sport

NSF Certified for Sport® testing confirms purity and absence of banned substances.

Minimal carbs and sugars

A typical serving contains about 6 g total carbohydrate and 1 g sugar (chocolate formula ~6 g carbs).

No artificial sweeteners or colors

Formulations use natural sweeteners like stevia and monk fruit in flavored versions and no artificial flavors or colors in the unflavored option.

Why It Works

Complete essential amino acid profile — Branched chain amino acids and natural electrolytes

Whey isolate supplies essential amino acids including leucine, isoleucine, and valine, plus naturally occurring sodium and potassium.

01

Branched chain amino acids

Each serving provides key BCAAs such as about 2,075 mg leucine, 1,240 mg isoleucine, and 1,125 mg valine.

02

Full amino acid breakdown

Contains measurable amounts of glutamine (~2,920 mg), lysine (~1,720 mg), and other indispensable amino acids per serving.

03

Low non‑protein additives

Unflavored option lists only whey protein isolate as the ingredient, useful when avoiding extra flavoring agents.

04

Electrolytes from whey

Whey isolate provides naturally occurring sodium and potassium (example: chocolate version lists about 120 mg sodium and 220 mg potassium per serving).

Klean Isolate PRODUCT DATA Sheet By  KLEAN ATHLETE

Klean Isolate DESCRIPTION

Klean Isolate by Klean Athlete is a NSF Certified for Sport® supplement that supplies 20 grams of high quality Whey Protein isolate in each serving. Klean Isolate can easily be added to any beverage to enhance daily protein and amino acid intake.

Klean Isolate is tested and certified by the NSF Certified for Sport® program, which was created to meet the growing demands of athletes, coaches and healthcare professionals to certify that sports supplements are safe and completely free from banned substances. Every product that carries the NSF Certified for Sport® mark has undergone stringent laboratory testing to confirm content, purity and compliance.

Whey protein FUNCTIONS

The dietary protein provided by Klean Isolate supplies essential amino acids, including branched chain amino acids that participate in many of the body’s metabolic and physiologic systems. Protein turnover in the body is continuous and can be substantial, and the rebuilding of skeletal muscle that is broken down during exercise is critically important to athletes. The dynamics of this constant degradation and re-synthesis demand a daily supply of dietary protein and their constituent amino acids. Essential or indispensable dietary amino acids must be supplied by the diet as they are not synthesized by the body.

Recent analyses of the dietary protein needs of people suggest that age and activity level may influence protein requirement for optimum health. Some scientists have also suggested that increased protein synthesis follows prolonged exercise. Athletes competing in body building or endurance sports may require significantly more total protein from food and supplements combined, typically in ranges of 1.0-1.5 g protein/kg of body weight.

Whey Protein isolate also contains naturally occurring electrolytes – sodium and potassium to help replenish hydration lost during activity.*

INDICATIONS FOR WHEY PROTEIN

Klean Isolate may be a useful dietary supplement for athletes who require additional amino acids for muscle integrity.
