If you are stirring collagen into coffee every morning for a year, flavour is not a nice-to-have. A powder that tastes of artificial vanilla in your espresso is a powder you stop taking by week three. But unflavoured is doing a lot of work on UK labels, and it does not always mean what buyers assume.
Unflavoured is the format most men end up wanting, because it disappears into whatever they already drink rather than adding another distinct flavour to the day. The trouble is that three different words get used interchangeably on the front of packs, and only one of them tells you anything reliable.
The Quick Answer
What Unflavoured Should Actually Mean
“Neutral” on the front of a pouch is a marketing word with no fixed definition, and “unflavoured” only tells you what has been left out. Neither tells you what the powder is like in a glass of water on a Tuesday morning, which is the only thing you actually care about.
What Unflavoured Collagen Actually Tastes Like
On its own, hydrolysed collagen has a mild savoury, faintly broth-like character. It is not unpleasant, but it is there, and it is most obvious in plain cold water, which is exactly how most people first try it.
A trace of stevia cancels it. In Revayo Prime that is 36.3mg in a 15g serving - 0.24% of the scoop, and a figure we print because we print all of them. It is not there to make the powder sweet. At that level it does not taste of anything. It is there to take the savoury edge off so the powder disappears into whatever you put it in.
That is the difference between a powder you take every morning without thinking about it and one you start finding excuses to skip. And it is worth being precise about what kind of sweetener, because “contains a sweetener” covers both a trace of a plant-derived one and a full artificial sweetening system. Those are not the same thing, and only one of them is on our label.
Source matters too. Marine collagen carries a more pronounced flavour than bovine and is harder to hide in a plain drink. If you intend to take yours in water and nothing else, that is worth knowing before you commit to a pouch of it.
How It Behaves in What You Actually Drink
Most hydrolysed collagen dissolves readily, but the experience differs by drink. This is a practical guide to what to expect rather than a claim about any particular product.
| Drink | How it mixes | What you will notice |
|---|---|---|
| Hot coffee or tea | Dissolves quickly with a normal stir | The easiest option. Flavour is effectively masked. Add the powder before the liquid to avoid clumping on the surface. |
| Cold water | Dissolves, but slower than in hot liquid | The real test. Coffee forgives everything, water forgives nothing. If a powder is clean in cold water it will be clean in anything. |
| Protein shake | Shakes in with no issue | Completely masked. Remember collagen is an incomplete protein and is not a replacement for your whey. |
| Oats or yoghurt | Stir through at the end | Undetectable. A good option if you dislike drinking it at all. |
| Fruit smoothie | Blends in fully | Undetectable, and the vitamin C in fruit is a natural pairing. |
What to Check Before You Buy
Where Unflavoured Is the Wrong Choice
Being straight about it: unflavoured is not the right answer for everyone.
If you want your morning drink to actually taste of something, buy a flavoured powder and enjoy it. There is no virtue in choosing the plain one and then dreading it. Unflavoured is for people who already have a drink they like and want the collagen to disappear into it.
For them the useful test is simple. Does it vanish into your coffee, your shake and your glass of water without you thinking about it, and can you see exactly what is in the scoop and how much of each? Because the best collagen powder is the one still in your cupboard in month six, not the one that scores highest on a spec sheet in month one.

Unflavoured Collagen FAQs
Does unflavoured collagen taste of anything?
On its own, hydrolysed collagen has a mild savoury note, most noticeable in plain cold water. A small amount of stevia neutralises it without making the powder taste sweet, which is why lightly sweetened unflavoured powders mix cleanly into anything.
Does Revayo Prime contain a sweetener?
Yes, 36.3mg of stevia per 15g serving, which is 0.24% of the scoop. It is there to neutralise the faint savoury note collagen has of its own, not to make the powder sweet. No sugars and no artificial sweeteners.
Can I put collagen in hot coffee?
Yes. Most hydrolysed collagen peptides dissolve readily in hot liquid. Adding the powder to the cup before the liquid helps avoid clumping on the surface.
Does marine collagen taste stronger than bovine?
Generally yes. Marine collagen carries a more pronounced flavour and is harder to mask in a plain drink such as water.
Can collagen replace my protein powder?
No. Collagen is an incomplete protein and should not replace whey, eggs, dairy, meat, fish, soy or other complete protein sources used to meet your overall protein needs.
What is in Revayo Prime?
Three ingredients: 14.77g FORTIGEL® hydrolysed bovine collagen peptides, 189.9mg Vitamin C and 36.3mg stevia per 15g serving. Unflavoured, 450g pouch, 30 servings, made in the UK.
