Introduction
Choosing between unflavoured vs flavoured protein is about more than just taste. It affects digestion, macro control, versatility and even sustainability. Whether you are new to supplements or fine-tuning your nutrition, this guide will help you understand the benefits of each option and why REP chose a customisable, unflavoured-first approach.
What Is Flavoured Protein?
Flavoured protein powders are pre-sweetened and pre-formulated. They usually include artificial or natural flavours, sweeteners and sometimes gums or thickeners.
Pros:
- Convenient and consistent
- Easy to mix and drink
- Comes in popular flavours like chocolate or vanilla
Cons:
- Fixed flavour, no flexibility
- May include sugar, sweeteners or colours
- Can cause digestive discomfort for some
- Harder to use in food or smoothies
What Is Unflavoured Protein?
Unflavoured protein contains no sweeteners, colours or flavouring agents. It’s a neutral base that offers complete control over how you use it.
Pros:
- No added sugar or sweeteners
- Easy to blend into any meal or smoothie
- Customisable with flavours of your choice
- Better for digestion in sensitive users
- Transparent, clean label
Cons:
- Requires additional flavour if you like a stronger flavour profile
- Might not appeal to first-time users without education
Why REP Chose Unflavoured First
At Ripple Effect Performance (REP), we design supplements to support your lifestyle, not restrict it. Our unflavoured whey protein isolate is 100% pure, free from added sugar, colours or sweeteners.
It pairs with a range of custom flavour tubs, so you can choose what to taste and when. No more flavour fatigue, wasted tubs or unnecessary sweeteners.
The Power of Custom Flavour Tubs
REP’s flavour tubs allow you to customise your shake, smoothie or oats with as little or as much flavour as you like.
Each scoop includes:
- 0g sugar
- 7–16 calories
- No unnecessary bulking agents
- Digestive enzyme blend for gut support
- Sucralose, a calorie-free non-nutritive sweetener
You can mix flavours, adjust intensity and enjoy flexibility no flavoured protein can match.
Mix and Match Your Favourite Flavours
One of the best parts about REP’s custom flavour system is that you’re not limited to one taste. Our current flavour tubs include Chocolate, Strawberry and Vanilla, and they’re designed to be used individually or blended together.
You can mix:
- Chocolate + Vanilla for a rich, dessert-style combo
- Strawberry + Vanilla for a berries-and-cream vibe
- Chocolate + Strawberry for a fruity, chocolate-dipped flavour twist
- All three together for a unique twist that keeps things fresh
You can mix flavours, adjust intensity and enjoy flexibility no flavoured protein can match.
Unflavoured Protein Prevents Waste
Flavoured protein powders often result in waste when people get tired of the same taste. With REP, you are not stuck with one option. You can switch flavours, go flavour-free or use your protein in baking, smoothies or oats without any clash in taste.
A First in the Industry: Custom Flavour System by REP
Most protein brands still stick to the traditional model. Flavoured protein tubs with fixed sweetness, taste and ingredients. REP flips that model completely.
Our separate flavouring system is one of the first of its kind in the South African fitness industry. Instead of locking you into one flavour, we give you an unflavoured, clean whey protein base that you can customise using optional flavour tubs.
No other major brands currently offer this modular, mix-and-match system, giving REP a unique position in the market for personalisation, macro control and reduced waste.
Why This Matters:
- Choose exactly how much flavour you want
- Mix flavours together for new taste combos
- Add protein to smoothies, oats or meals without flavour clashing
- Save money and reduce waste by avoiding unwanted tubs
