A different way to experience protein

For decades, protein has meant a thick, creamy shake after training. But what about during it? Training in the gym, playing sports, cycling, running, hiking: those moments have belonged to water, sports drinks and amino supplements. Many people don't want a heavy, milky shake mid-session. ISO KING CLEAR is a refreshing protein drink made for those active moments, not just the post-workout routine.
Protein doesn't replace water. Keep drinking water as you train; CLEAR adds protein to the moment.
The CellOnePro™ story
Everybody wants more protein, and whey keeps getting harder to source and more expensive. Some brands answered with compromise. We went looking for a better way.
We set three rules: quality, flavor, fair price. Many options passed one or two. We kept looking until one passed all three.
Ancient biology. Modern technology.The future of protein.

Where protein comes from

Milk, eggs, meat. The classic sources, tied to farms and herds, and to the dairy supply.

Soy, peas, rice. Extracted from crops, tied to fields and harvests.

Protein-rich yeast, cultivated under controlled conditions and grown by fermentation. Not dependent on dairy production or agricultural harvests. This is CellOnePro™.
No dairy farm. No crop field. A controlled fermentation.

Ancient biology
CellOnePro™ starts with Saccharomyces cerevisiae, the same species of yeast people have used for thousands of years to bake bread and brew. It is not ordinary baker's yeast: controlled fermentation and advanced processing turn it into a concentrated, high-quality protein.
How CellOnePro™ is made

Selected Saccharomyces cerevisiae yeast is cultivated in a carefully controlled fermentation environment. The yeast grows and produces cellular material naturally rich in protein and amino acids.

Advanced processing opens and breaks down the yeast's cellular structure, making the protein inside accessible for extraction and refinement.

Specialized separation and purification remove unwanted non-protein components and concentrate the valuable protein fraction.

The protein is tailored to its job. For ISO KING CLEAR, an extra step of hydrolysis breaks it into smaller peptides, so it dissolves into a clear drink. For ISO KING, a grade built for smooth, creamy shakes.
The result: a highly refined, animal-free protein, complete with all nine essential amino acids.
Hydrolyzed CellOnePro™
Clear protein drinks need excellent solubility, a light mouthfeel and minimal cloudiness. ISO KING CLEAR uses a hydrolyzed CellOnePro™ grade: hydrolysis breaks larger proteins into smaller peptides, so the protein dissolves into a light, clear, fruity drink instead of a milky shake. Same complete protein. A completely different way to drink it.

What's in the scoop
Proteins are built from amino acids, and nine of them are essential: your body cannot make them in sufficient amounts, so they have to come from food. A complete protein delivers all nine. Every scoop of ISO KING CLEAR does, without depending on dairy.
Three of the nine, leucine, isoleucine and valine, are the branched-chain amino acids, or BCAAs. They are part of the nutritional profile athletes look for when they choose a protein, and ISO KING CLEAR has 5,300 mg per scoop.
Total EAAs 11,830 mgTotal BCAAs 5,300 mg
110 calories0 g sugar0 g fat per scoop

Why wait until after your workout?
Sip refreshing, complete protein while you train to supply essential amino acids, support recovery, and stay hydrated.
Three flavors
Same 25 g of complete protein in every flavor. Choose one and we set it in the order box for you.

A bold, sweet-and-tangy mixed fruit punch. The classic sports-drink flavor, now with 25 g of protein.

Bright, tart pink lemonade with a sweet finish. Made for hot days and long sessions.

Crisp, tangy green apple. Light and refreshing, sip after sip.

ISO KING CLEAR is a light, fruity, clear protein drink powered by CellOnePro™. Each scoop gives you 25 g of complete protein with all nine essential amino acids, 110 calories, 0 g sugar and added electrolytes (sodium, potassium and magnesium). It is made to sip during training and active moments, not just after.
CellOnePro™ is proprietary, patent-pending single cell protein technology. It starts with Saccharomyces cerevisiae, a protein-rich yeast, cultivated in a controlled fermentation. Advanced processing opens the cells, separates and concentrates the protein, and refines it for its job. The result is a highly refined, animal-free protein with all nine essential amino acids.
ISO KING CLEAR uses a hydrolyzed CellOnePro™ grade. Hydrolysis breaks larger proteins into smaller peptides, which gives the excellent solubility, light mouthfeel and minimal cloudiness a clear drink needs. So it mixes into a light, clear, fruity drink instead of a milky shake, with the same complete protein.
No. ISO KING CLEAR is made with CellOnePro™, a hydrolyzed single cell protein isolate from yeast (Saccharomyces cerevisiae), grown by controlled fermentation. It is not whey and not from milk, and it is dairy free and lactose free.
No. CellOnePro™ starts with the same species of yeast people have used for thousands of years to bake bread and brew, but it is not ordinary baker's yeast. It is a sophisticated protein ingredient: controlled fermentation and advanced processing turn it into a concentrated, high-quality protein.
Both are powered by CellOnePro™ and give you 25 g of protein with all nine essential amino acids per serving. ISO KING CLEAR uses a hydrolyzed grade with added electrolytes for a light, fruity drink you can sip while you train. ISO KING uses a grade selected for creamy shakes, for after training or any time of day. The difference is the experience, not our commitment to quality.
During training and active moments: in the gym, playing sports, cycling, running or hiking. It also fits any time of day. Use it as part of a balanced diet and exercise program.
No. ISO KING CLEAR adds protein to the moment. Protein does not replace your hydration and electrolyte needs, so keep drinking water as you train.
No. It is light and fruity, closer to a fruit-flavored sports drink than a thick, creamy shake. Choose from Fruit Punch, Pink Lemonade and Green Apple.
Add 1 scoop to 16 oz of cold water in a shaker bottle and shake for 20-30 seconds. Adjust the water to the flavor strength you like.
About 20 servings. ISO KING CLEAR comes in one size, $49.99 per tub, and every serving is one scoop with 25 g of protein.
