Whey Protein Made Simple — Your Complete Guide (2025)
Everything you need to know about whey for recovery, muscle gain, and everyday wellness — plus how our blend is formulated for taste, digestion, and real-world results.
High-Quality Protein Easy on Digestion Great Taste & Texture With Digezyme®
In the world of nutrition and fitness, whey protein has earned its reputation for supporting recovery, lean mass, and overall health. This guide breaks down the essentials — the differences between WPC and WPI, why digestion matters, how our formula uses Digezyme® for comfort and absorption, and which flavours and sizes fit your routine.
Quick Facts
| Main types | Whey Protein Concentrate (WPC) · Whey Protein Isolate (WPI) · Casein (slow release) |
|---|---|
| Key differences | WPC = creamier mouthfeel, some fat & lactose · WPI = higher protein %, lower fat & lactose |
| Best timing | Post-workout (fast amino availability) · Between meals for protein targets |
| Our angle | Balanced blend for taste + texture, easy digestion with Digezyme®, and consistent mixability |
Types of Whey — What’s the Difference?
WPC (Whey Protein Concentrate) keeps more of whey’s natural fractions, delivering a creamier texture and fuller flavour, with a modest amount of fat and lactose. It’s versatile, satisfying, and ideal for everyday shakes.
WPI (Whey Protein Isolate) is refined for a higher protein percentage with most fat and lactose removed. It’s a great option for lean phases, peri-workout use, or anyone watching lactose intake.
Casein is a slow-release milk protein. In small amounts, it can improve body and creaminess, supporting more sustained amino acid delivery — handy between meals or before bed.
WPC vs WPI — Which Should You Choose?
WPC — Everyday Comfort
- Creamier texture and a naturally rich flavour profile
- Great for daily use and general nutrition goals
- Contains a little fat and lactose (most tolerate it well)
WPI — Lean & Fast
- Higher protein per serve with less fat and lactose
- Ideal post-workout or in a calorie-conscious phase
- Mixes light and goes down clean
Why Digestion Matters — Meet Digezyme®
Digezyme® is a multi-enzyme complex (amylase, protease, lipase, cellulase, lactase) included to support comfortable digestion and efficient uptake. For many people, enzymes can help break down protein, carbs, fats, and lactose — making a shake feel lighter and more consistent day to day.
- Comfort: Enzyme support can reduce the “heavy” feeling some get with lower-quality whey.
- Absorption: Well-digested protein is more likely to be well-utilised.
- Consistency: Helps your shake behave the same way every time you mix it.
Why We Blend — Texture, Taste, and Real-World Use
Our whey formula balances the strengths of WPC and WPI, with a touch of casein and whey powder to nail that milk-like creaminess in water — without relying heavily on gums or thickeners. The result is a shake that mixes smoothly, tastes great, and supports your goals whether you’re leaning out, building, or maintaining.

FAQs
What are the main differences between WPC and WPI?
WPC delivers creamier texture and flavour with a little fat and lactose; WPI offers higher protein per serve with most fat and lactose removed. Many people use both depending on the context (daily shake vs. post-workout).
What is Digezyme® and why include it?
Digezyme® is a blend of enzymes (amylase, protease, lipase, cellulase, lactase) to support comfortable digestion and consistent uptake — helpful for those who want a lighter-feeling shake.
How is this blend different to standard whey?
We balance WPC + WPI for taste and performance, add a small amount of casein/whey powder for body/texture, and include Digezyme® for digestion — aiming for real-world mixability and flavour without heavy reliance on gums.
Flavours and sizes?
Eight flavours (see above) in 2lb and 5lb. Pick flavour by taste, size by frequency and budget.
Suitable for dietary sensitivities?
Most people tolerate our blend well. If you’re very lactose sensitive, WPI-leaning serves may suit you better. If you have medical conditions, chat with your healthcare professional.
