High protein yoghurt with no sweeteners

Published 29 October 2026

The best place to find high protein yoghurt with no sweeteners is the plain pots: skyr, quark and Greek yoghurt. The ones below have 9g to 12g of protein per 100g, and the list is just milk, yoghurt or cultures.

Many "protein" yoghurts with fruit or flavour add sweeteners, gums or sugar. This guide shows plain ones that don't, and how to check a pot.

What is the best high protein yoghurt in the UK?

We don't rank them. But we can show you the ones that pass our rules. All of these:

  • have 9g or more protein per 100g, from the label
  • have no sweeteners
  • have no added sugar
  • have no gums or thickeners

Quark has the most protein of the pots we've checked:

Skyr comes next:

Greek and Greek-style yoghurt:

Is protein yoghurt ultra processed?

It depends on the pot. A plain skyr made from milk and cultures has a very short list. A flavoured protein pot might list sweeteners, flavouring, starch and gums.

The word "protein" on the front won't tell you. The list on the back will. We don't use the word "ultra processed" for single products. We just check the list against our rules.

What sweeteners are in protein yoghurt?

These are some you may see. Each is on the FSA's list of approved additives:

  • E950 acesulfame K
  • E951 aspartame
  • E955 sucralose
  • E960 steviol glycosides (stevia)

Our rules leave out sweeteners. We make an exception for stevia and monk fruit. But none of the pots on this page use any sweetener at all.

Some people choose to avoid sweeteners. Some prefer to add their own fruit or honey. We don't make claims either way.

How to check a yoghurt label

  1. Find "Ingredients". If it says just "milk", "yoghurt" or "skimmed milk", that's a plain pot.
  2. Look for "sweetener", or the E numbers above.
  3. Look for "sugar", "fructose" or "syrup".
  4. Look for "thickener", "starch" or "gum".
  5. Check protein per 100g in the nutrition table.

The protein number is per 100g. Many pots are bigger than that. A 150g pot of skyr with 10g per 100g has about 15g in total.

What's the difference between skyr, quark and Greek yoghurt?

They are all made from milk. They are strained in different ways.

  • Greek and Greek-style yoghurt are strained to make them thick. Full fat ones taste rich and creamy.
  • Skyr is from Iceland. It is very thick and often made with skimmed milk.
  • Quark is a soft cheese, not a yoghurt. It is smooth and mild. In our checks, it had the most protein of the three.

All three work in sweet and savoury food.

Is full fat or fat free yoghurt higher in protein?

Fat free pots are often a little higher in protein per 100g. That's because there is less fat in each spoon. But full fat pots can still be high. Check the nutrition table. Both kinds can pass our rules, as long as the list is short.

How to make plain yoghurt taste good

Plain pots can taste sharp. Here are some ideas:

  • add berries, banana or grated apple
  • stir in a little cinnamon
  • top with nuts and seeds
  • mix with garlic, lemon and salt for a dip
