20 Grams of Protein. A Clear Role in Your Routine.

ZIsolate supplies 20 g total protein per 25 g serving. That gives you a measured amount to include alongside the protein in your regular meals.

The formula contains both whey protein isolate and collagen. The label does not disclose their individual quantities, so the 20 g figure should be understood as total protein—not 20 g of whey protein isolate alone.

This distinction matters. Clear product information helps you compare formulas and make informed choices.

What Is Inside ZIsolate?

The label lists the following ingredients:

Whey protein isolate, fudge powder, natural and artificial flavors, soy lecithin, sunflower, collagen, sucralose, and salt.

Whey Protein Isolate: The First Listed Ingredient

Whey protein isolate is a milk-derived protein ingredient. It supplies essential amino acids and is the first ingredient in the ZIsolate ingredient list.

ZIsolate’s label presents protein as supporting muscle maintenance and growth alongside resistance training and adequate nutrition. It identifies the ingredient as whey protein isolate, without describing it as hydrolyzed whey.

Collagen: An Additional Protein Ingredient

Collagen contributes another protein source to the formula.

The label does not specify its source, amount, or processing method. For that reason, the formula should not be described as exclusively whey protein isolate, and the label does not establish a collagen dose for specific skin or joint benefits.

Fudge Powder and Flavorings: Part of the Taste Experience

Fudge powder, together with natural and artificial flavors, contributes to the flavor formulation.

The label does not provide the separate composition of the fudge powder. For the finished product’s nutritional contribution, use the Nutrition Facts panel: 0 g total sugars and 1 g total carbohydrate per labeled serving.

Soy Lecithin: A Formulation Ingredient

Soy lecithin is commonly used to help ingredients disperse and combine in powdered foods.

Because the formula includes soy lecithin, the package declares soy as an allergen.

Sunflower: Listed Without a Specific Form

The ingredient list says “sunflower.” It does not specify whether this refers to sunflower lecithin, oil, powder, or another ingredient.

The exact form requires clarification from the brand.

Sucralose and Salt: Sweetness and Flavor

Sucralose contributes sweetness. Salt contributes to the flavor formulation.

The finished powder contains 0 g added sugars and 120 mg sodium per 25 g serving, according to the label.

Why Choose ZIsolate?

Protein Without a Complicated Preparation Routine

You do not need a blender full of ingredients to prepare a protein drink.

ZIsolate can be mixed with cold water or milk according to the package directions. Keep preparation simple when convenience matters, or account for additional ingredients when creating a more substantial recipe.

A Defined Carbohydrate and Fat Profile

Each labeled serving contains 1 g carbohydrate and 0.5 g fat.

These figures make it straightforward to track what the powder contributes. You can then choose the rest of your meal or shake ingredients according to your preferences.

Low carbohydrate content does not mean calorie-free. Each 25 g serving provides 90 calories.

Protein to Complement Your Training

The label identifies muscle maintenance and growth as benefits associated with protein intake.

ZIsolate can contribute protein to a routine that includes consistent resistance training and adequate overall nutrition. Its role is to supplement your intake; a shake does not replace the rest of that routine.

Convenience Beyond the Gym

Protein powder has a place outside the changing room.

A measured serving can fit an office break, breakfast preparation, or a busy afternoon at home. Choose the occasion where it helps you organize your food intake.

The advantage is practical: a protein option that is available when you have planned to use it.

“No Lactose” Does Not Mean “No Milk”

ZIsolate carries a “No Lactose” statement, but it contains milk-derived protein and declares milk as an allergen.

Lactose and milk protein are different components. The product should therefore not be described as dairy-free or suitable for people with a milk allergy.

The supplied label does not provide a lactose testing threshold or laboratory result.

How to Mix ZIsolate

The package’s Suggested Use section states:

1. Mix one scoop, identified as 20 g, with 160–200 mL cold water or milk.

2. Shake or stir until dissolved.

3. Enjoy after exercise or whenever you want to add protein to your diet.

Check the serving weight: the mixing directions specify 20 g powder, while the Nutrition Facts panel uses 25 g. Confirm the intended scoop size with Z Nutrition. Do not assume a 20 g scoop delivers the nutrition listed for a 25 g serving.

Water or Milk?

Your preparation	What to account for
Cold water	No added calories or macronutrients
Milk	Additional protein, carbohydrates, fat, and calories according to the milk
Lactose-containing milk	Adds lactose to the finished drink
Fruit or other additions	Changes nutrition according to the ingredients and portions

For accurate tracking, calculate the complete recipe.

When to Use ZIsolate

The label suggests use after exercise or whenever you want additional dietary protein.

That could mean alongside breakfast, between meals, or at another convenient point in your day. Your serving should fit your overall intake and the confirmed package directions.

The supplied label does not establish a fixed number of servings per day.

Storage and Important Product Information

Keep ZIsolate tightly sealed in a cool, dry place, away from heat, moisture, and direct sunlight.

Keep it out of reach of children. Do not use the product if the package is damaged or the seal is broken.

Contains milk and soy.

The package instructs users to consume the product as supplemented food only and states: “Do not use for weight reduction.” ZIsolate should therefore be positioned as a protein option alongside food, rather than as a weight reduction product or a complete meal replacement.
