Whey More Than You Think: Understanding Protein Types

With so many new protein powders and protein innovations hitting the market, it is hard sometimes to truly know what each protein is, what it does, why its good, and why it should be used. In this article it will a simplified version of what each type of protein is and what it is good for!

What does the term “Whey” mean?

Whey quite simply means derived from milk. There are several different types of “Whey” that will be explained later in this article such as whey isolate, whey concentrate, and whey casein. The biggest thing you need to take away when you hear the word “Whey” means this protein is sourced from a milk product compared to a whole food or vegan source.

Whey Isolate

Description:
Whey isolate is a highly filtered form of whey protein that contains 90% or more protein per serving with minimal fats and carbohydrates. It’s ideal for those looking for quick digestion and low lactose content.

Best for:

• Lean muscle building
• Post-workout recovery
• People with mild lactose sensitivity
• Great Lean and High-Quality Absorbtion protein source.
• Great for smoothies and protein balls

Examples:

Rule1 Isolate, Clear Isolate, Lean Whey, Bucked Up RTD

Whey Concentrate

Description:
Whey concentrate is a less processed form of whey protein, containing about 70–80% protein, with some fats and carbs remaining. It has a creamier texture and typically a richer flavor than isolate.

Best for:

• Overall fitness goals
• People looking for a cost-effective protein
• Those who don’t mind a small amount of lactose

Whey Casein (usually just “Casein”)

Description:
Casein is the other primary protein in milk. Unlike whey, it digests slowly, providing a steady release of amino acids over several hours. It’s great for preventing muscle breakdown during periods of fasting—like sleep.

Best for:

• Nighttime supplementation
• Long-lasting satiety
• Anti-catabolic support
• Good For Baking

Examples:

Rule1 Casein

Whey Blend

Description:
Whey blends combine multiple types of whey—usually isolate, concentrate, and sometimes hydrolysate—to provide both fast and moderately digested proteins. This creates a balanced release of amino acids.

Best for:

• All-day muscle support
• Those who want benefits of different whey types
• People looking for value and versatility
• Great for Cooking

Examples:

Core Nutritional’s Pro, Rule1 Whey Blend 

Vegan Protein

Description:
Vegan proteins are plant-based and often made from sources like pea, brown rice, hemp, chia, or pumpkin seeds. While not all plant proteins are complete on their own, blends are often used to create a full amino acid profile.

Best for:

• Vegans or vegetarians
• People with dairy allergies
• Sensitive stomachs

Examples:

Core Vegan

Whole Food Protein

Description:
Whole food proteins come from real, minimally processed food sources like beef, egg whites, chicken, or bone broth. These powders offer protein in a more “natural” format, often with added nutrients and digestive enzymes.

Best for:

• People avoiding dairy and soy
• Those wanting fewer additives and cleaner ingredients
• Support for gut health and food-based nutrition

Examples:
