Read More about Coffee Protein Powder - Your Shake, Now With a Kick

Not everyone wants their shake to taste like dessert. Some people just want it to taste like the coffee they're already drinking — which is really the whole reason this flavour exists, for anyone stacking protein on top of a coffee habit instead of swapping it out.

Note: this is a coffee-flavoured protein — flavoured with coffee extract for taste, not dosed with caffeine as a stimulant. If you're looking for a caffeine boost specifically, check the product label for actual caffeine content before assuming it's there.

Coffee Protein — Isolate, Concentrate, or Plant

Like our other flavours, coffee sits on top of whichever base protein you pick — the macros and protein source stay identical to the same base in any other flavour. Available across all three: whey protein isolate, whey protein concentrate, and plant protein.

Who Coffee Flavour Is For

If chocolate and vanilla both read as "dessert" to your palate, coffee is the alternative — bitter-leaning, not sweet-forward, and it pairs naturally with your actual coffee rather than competing with it. It's a strong pick for a mid-morning or pre-workout shake where you'd otherwise be having a coffee anyway.

Is Putting Protein Powder in Coffee Okay?

Yes — mixing whey protein into coffee, hot or cold, is a common and safe way to combine your caffeine habit with your daily protein intake. The main practical issue is texture: whey can clump in very hot liquid, so it mixes best in warm-to-cold coffee, or blended rather than stirred. A coffee-flavoured protein sidesteps the taste clash entirely, since it's already designed to work with coffee rather than against it.

Is Coffee Protein Powder Good for You?

A coffee protein built on isolate or concentrate gives you the same benefits as any other flavour — complete protein, essential amino acids, support for muscle recovery — plus the convenience of pairing directly with your coffee. Whether it's "good for you" mostly comes down to what's in the base: 0g added sugar and no artificial sweeteners, as ours has, beats a heavily sweetened flavoured protein.

How to Use It

Mix one scoop with 300–350ml cold water or milk, or blend with ice for a protein iced coffee. It also works stirred into an actual cup of coffee if you want to combine the two rather than choosing one — since it's flavour-matched, it won't clash the way vanilla or chocolate protein would. Want to try it before committing to a full tub? Our single-serve sachets are available in coffee too.


FAQs

Does coffee protein contain caffeine?

This is a coffee-flavoured protein, flavoured for taste rather than formulated as a caffeine source. Check the product label for exact caffeine content before relying on it for a stimulant effect.

Can I mix coffee protein into my actual coffee?

Yes — because the flavour is coffee-matched, it blends into black coffee, cold brew, or lattes without the clash you'd get from a chocolate or vanilla protein.

Will coffee protein powder cause bloating or digestion issues?

Depends on the base, not the coffee flavour. Concentrate carries more lactose than isolate, so it's more likely to cause bloating if you're lactose-sensitive — plant protein avoids that but can cause mild bloating from added fiber in people unused to it.

Which base should I choose in coffee — isolate, concentrate, or plant?

Isolate for the highest protein density and lowest lactose, concentrate for everyday value, and plant if you're vegan or dairy-free. The coffee flavour profile is consistent across all three.
