With up to 25 grams of protein per serving and an award-winning formula, many fitness enthusiasts wonder exactly what is iso100 protein made of. At its core, ISO100 features a blend of premium hydrolyzed and isolated whey protein, meticulously processed for superior purity and rapid digestion.

Quick Summary

Dymatize ISO100 protein contains a high-quality blend of hydrolyzed whey protein isolate and whey protein isolate, filtered for low carbs, fat, and lactose. This results in a fast-absorbing formula ideal for muscle recovery and lean mass growth.

Key Points

Core Composition: Dymatize ISO100 is primarily made from a blend of hydrolyzed whey protein isolate and whey protein isolate.
Ultra-Purity: A multi-step microfiltration process removes excess carbs, fat, and lactose, resulting in a cleaner product.
Rapid Absorption: The hydrolysis process pre-digests some of the protein, breaking it into smaller peptides for ultra-fast absorption.
Low in Fats and Carbs: The filtration process makes ISO100 a very lean protein, ideal for those seeking to control calories and macros.
High in BCAAs: The formula is naturally packed with branched-chain amino acids, vital for muscle growth and recovery.
Enhanced Digestion: Due to the low lactose content and hydrolyzed nature, ISO100 is generally well-tolerated by those with sensitive stomachs.
Flavoring Ingredients: Additives for taste and mixability include natural and artificial flavors, sweeteners like sucralose and stevia, and soy lecithin.

The Primary Ingredients: Hydrolyzed and Isolated Whey

At the heart of the ISO100 formula are its two primary protein sources: whey protein isolate and hydrolyzed whey protein isolate. These are derived from cow's milk and undergo a multi-step purification process to remove excess carbs, fat, lactose, and cholesterol.

Whey Protein Isolate: This highly purified form of whey contains 90% or more protein. The process removes most fat and lactose, making it easily digestible.
Hydrolyzed Whey Protein Isolate: This advanced whey is partially broken down into smaller peptides, allowing for ultra-fast digestion and absorption.

Flavoring and Additive Components

Besides the main protein sources, other ingredients add taste, texture, and mixability. These are typically present in small amounts and vary by flavor.

Flavors: Natural and artificial flavors contribute to the diverse range of ISO100 flavors.
Sweeteners: A blend of artificial sweeteners, such as sucralose and steviol glycosides, provides sweetness.
Emulsifier: Soy lecithin is included for smooth mixing with liquids.
Other Additives: Minor ingredients may include salt, potassium chloride, and sometimes cocoa powder or edible glitter.

How ISO100 Compares to Other Whey Proteins


Feature	Whey Concentrate	Whey Isolate	ISO100 (Hydrolyzed Isolate Blend)
Processing	Basic filtration; retains some fat and lactose.	Extensive filtration; removes most fat and lactose.	Hydrolysis + extensive filtration; pre-digested.
Protein Content	70–80%.	90% or higher.	Up to 90% in some formulations.
Absorption Rate	Slower.	Faster than concentrate.	Fastest among the three types.
Carb/Fat Content	Higher.	Lower.	Extremely low.
Cost	Least expensive.	More expensive than concentrate.	Most expensive due to extra processing.
Best For	Budget-conscious users, general nutrition.	Those seeking high protein with less fat/carbs.	Competitive athletes needing maximum recovery speed.

Benefits of ISO100's Formulation

ISO100's composition offers several benefits for athletes.

Rapid Muscle Recovery: The hydrolyzed whey helps amino acids quickly reach muscles for repair and synthesis.
Lean Muscle Support: Its low fat and carb content provides a clean protein source for building and maintaining lean mass.
Improved Digestion: The pre-digested and low-lactose formula can reduce digestive discomfort.
High BCAA Content: As a complete protein, ISO100 is rich in BCAAs and EAAs essential for muscle growth.

A Look at Other Ingredients

A typical ingredient list for a flavor like Cookies & Cream includes Hydrolyzed Whey Protein Isolate, Whey Protein Isolate, Natural and Artificial Flavors, and less than 2% of ingredients such as Cocoa Powder, Soy Lecithin, Sucralose, Salt, Potassium Chloride, and Steviol Glycosides.

Conclusion

ISO100 protein is primarily a blend of hydrolyzed and isolated whey protein, processed for purity and rapid absorption. This results in an ultra-pure, fast-digesting formula with low fat and carbs. While more expensive due to processing, its speed and purity make it a premium choice for muscle recovery and lean mass gains.

Frequently Asked Questions

ISO100 protein is composed of a combination of hydrolyzed whey protein isolate and whey protein isolate, both derived from milk.

Hydrolyzed whey is a version of whey protein that has been partially broken down into smaller, easily digestible peptides. This allows for faster absorption than standard whey isolate or concentrate.

Yes, ISO100 is manufactured using a purification process that filters out excess fat, carbs, lactose, and cholesterol, resulting in a very lean macronutrient profile.

Due to its extensive filtration process, ISO100 is very low in lactose, which makes it a more suitable option for many people with lactose sensitivity compared to less refined whey proteins.

Yes, as a complete protein, ISO100 is rich in naturally occurring Branched-Chain Amino Acids (BCAAs), including leucine, isoleucine, and valine, which are crucial for muscle support.

It is fast-digesting because of the inclusion of hydrolyzed whey protein isolate, which is partially pre-digested and absorbs more quickly into the bloodstream.

Beyond the protein, ISO100 contains ingredients such as natural and artificial flavors, sweeteners like sucralose and stevia, salt, and soy lecithin for mixability.
