Unflavoured Whey Protein: Isolate, Concentrate and Plant

Func. Lab unflavoured protein comes in three bases: whey protein isolate, whey protein concentrate and plant protein made from pea and rice. Each unflavoured jar lists 25 g to 30 g of protein per scoop and 0 g of total sugar, with no added sugar, no sweetener and no flavouring. The product pages list the protein plus a digestive enzyme blend, and nothing else you would taste.

Whether you search for unflavoured, unflavored, flavourless or plain whey protein powder, they all mean the same thing: protein with no flavour added, so you decide what it goes into.

What Is Unflavoured Whey Protein?

Unflavoured whey protein is a plain protein powder with no cocoa, no vanilla, no coffee and no sweetener added. What you taste is the protein itself, which is why it suits people who find flavoured powders too sweet and people who want to add protein to food rather than drink a shake. The product pages name bromelain and papain, two digestive enzymes, as the only addition to the protein.

Which Unflavoured Whey Protein Base Should You Choose?

Choose whey protein isolate if you want the most protein per scoop with the least fat. Whey protein isolate is more refined than concentrate, so it carries less lactose, which many people with a sensitive stomach find easier. Choose whey protein concentrate if you want a slightly creamier whey and are happy with a little more fat and carbohydrate per scoop. Choose plant protein if you avoid dairy: it is vegan, lactose-free and made from pea and rice isolates. Our isolate vs concentrate guide goes through the trade-offs in more depth.

Does Unflavoured Whey Protein Taste Bad?

Taste is personal, but unflavoured is the mildest option you can buy because nothing has been added to cover or change it. Whey tends to taste faintly of milk, and some people find plain pea protein a little earthy, so mixing it with cold milk, a banana or a spoon of cocoa makes it easier to drink. Ratings and reviews from other buyers are on each product page, and the travel packs below let you try it before you buy a full jar.

Is Unflavoured Protein Powder Better for You?

The protein is the same as in any other flavour of the same base, so unflavoured is not stronger or healthier. The difference is what is not in it. There is no added sugar and no sweetener to taste, and no flavouring that can clash with what you are cooking. Func. Lab's flavoured powders also list 0 g of total sugar, sweetened with stevia and monk fruit, so the real choice is between a flavoured shake and a plain base you can use in recipes. For how to read any protein label, see our protein powder label cheat sheet.

What Is in Unflavoured Protein Powder?

Per the product pages, unflavoured whey protein isolate is whey protein isolate and a digestive enzyme blend, unflavoured concentrate is whey protein concentrate and the same enzyme blend, and unflavoured plant protein is pea and rice protein isolate and the enzyme blend. The listings state no artificial preservatives and no gums, and the isolate listing also states no anti-caking agents or chemical thickeners. Func. Lab says its products are FSSAI compliant and third-party tested, and the certificates are on our certifications page.

Does Unflavoured Protein Powder Cause Bloating, Gas or Acne?

It depends on the base more than the flavour. Whey protein concentrate carries more lactose than whey protein isolate, so people who are lactose sensitive are more likely to notice gas or bloating with concentrate. Plant protein has no dairy at all, though any new protein can take a few days to settle, so start with one scoop. On acne, some research links whey protein to breakouts, mostly in people who are already prone to them. If your skin reacts after you start any new supplement, stop and see what changed. Our whey protein side effects guide covers what the science says.

Is Whey Protein Safe for the Kidneys?

For most healthy adults, a normal serving of protein powder as part of a balanced diet is not linked to kidney problems. If you have kidney disease or reduced kidney function, check with your doctor before you add any protein supplement, plain or flavoured.

How to Use Unflavoured Protein Powder

The directions on every unflavoured product page are the same: mix one scoop into 300 to 350 ml of water or plant-based milk. Use it after a workout, between meals, or as a base in recipes.

Add 300 to 350 ml of cold water or plant-based milk to a shaker.
Add one scoop of unflavoured protein powder.
Shake for 20 to 30 seconds until no clumps remain.
Drink it straight away, or pour it over oats or into a smoothie.

How to Add Unflavoured Protein to Food

The product pages suggest smoothies, protein pancakes and iced coffee. This is an easy way to add it to your morning oats, curd or yogurt: mix it into the oats once they have cooled slightly, or into a pancake or dosa batter. For savoury food such as dal or soup, mix the scoop with a splash of cool water first and stir it in once the pot is off the heat, because whey can clump in very hot liquid. Heat does not change how much protein is in the scoop.

Tip: make a paste with a splash of cool water or milk before adding the scoop to anything warm. It stirs in far more evenly than powder dropped straight into a hot pan.

Who Unflavoured Protein Is For

Unflavoured suits people who find flavoured shakes too sweet, people who cook with protein, and anyone who wants a plain base to flavour themselves with fruit, cocoa or coffee. If you would rather have the flavour already done, our coffee protein range is the nearest alternative.
