People choosing a drink after exercise
A ready-to-drink milkshake is convenient, but its labelled protein contribution matters if it is intended to be the main part of a post-workout snack rather than accompany food.
Who is comparing these drinks?
Shoppers comparing standard and protein-enriched shakes
Protein, sugars and serving sizes differ between the labelled Yazoo, Mars and Pro Mlk examples. Compare the quantity you plan to drink, not just the size of the pack or wording on its front.
People checking ingredients and allergens
Milk is listed for the Yazoo, Mars and Pro Mlk drinks discussed here; the Mars drink also lists barley. The current pack’s ingredients and allergen statement are decisive if you need to avoid either ingredient.
What should you check before choosing?
Start with the amount you expect to drink, then compare protein and sugars for that amount. A no-added-sugar claim is a separate consideration, not a third type of drink that excludes standard or protein-enriched options.
Protein-enriched shake
Consider it when: The drink needs to contribute more protein to your snack; Pro Mlk states 25.7g per 330ml serving for its Chocolate Protein Shake.
Bear in mind: This example contains milk, and a protein-enriched label does not tell you its sugars or whether it fits the rest of your snack.
Standard flavoured milkshake
Consider it when: You want a ready-to-drink flavoured milk snack and its labelled protein contribution is enough for what you intend to have.
Bear in mind: The Yazoo and Mars 400ml examples each contain two 200ml servings, so a whole bottle is not one labelled serving.
| Priority | What to check | Your needs |
|---|---|---|
| Protein contribution | Compare protein for the amount you will drink, noting whether the label uses 100ml or a larger serving. Yazoo states 3.3g per 100ml for Chocolate; Tesco Groceries lists 3.5g per 100ml for the Mars drink; Pro Mlk states 25.7g per 330ml serving for its Chocolate shake. | I want to know how much protein the drink adds to my snack, particularly if I am choosing between a standard milkshake and a protein-enriched one. |
| Sugars and claims | Read sugars per 100ml and for the amount you plan to drink. Yazoo lists 8.6g per 100ml; Tesco Groceries lists 6.5g per 100ml for Mars. Check the ingredients as well as any no-added-sugar wording. | A no-added-sugar claim matters to me, but I do not want to mistake it for a sugar-free drink. The Mars example still lists sugars. |
| Pack and serving size | Check the bottle volume and servings per pack. The Yazoo and Mars 400ml examples are divided into two 200ml servings; use the nutrition information for the quantity you actually drink. | Will I drink the full bottle after exercise or keep some for another occasion? That changes the amount represented by the per-serving figures. |
| Ingredients and allergens | Read the current pack’s ingredient list and allergen statement. The Yazoo and Pro Mlk examples contain milk; the Mars example contains milk and barley. | I need to avoid an ingredient, so flavour or protein figures cannot make an unsuitable drink an option for me. |
What is easy to overlook?
-
Assuming a large bottle provides a large protein serving
Bottle volume alone does not establish protein content. Pro Mlk states 25.7g protein per 330ml serving for its Chocolate shake, while Yazoo and Tesco Groceries list 3.3g and 3.5g respectively per 100ml for the Yazoo and Mars flavoured drinks.
Compare the labelled protein for the quantity you intend to drink before deciding whether it meets the purpose of your snack.
-
Treating a 400ml bottle as one labelled serving
The Yazoo and Mars examples each contain two 200ml servings. Drinking the whole bottle means consuming twice the amounts shown per 200ml serving.
Check servings per pack and use the nutrition panel to work out the amount for your planned portion.
-
Reading ‘no added sugar’ as ‘sugar-free’
The Mars No Added Sugar drink contains naturally occurring sugars; Tesco Groceries lists 6.5g sugars per 100ml.
Check the sugars line for the amount you will drink and read the ingredients if sweeteners affect your choice.
-
Overlooking allergens on a protein drink
The Yazoo, Mars and Pro Mlk examples contain milk, and the Mars example also lists barley. A workout-focused description does not change those ingredients.
If you need to avoid an ingredient, check the current pack’s ingredients and allergen statement before buying or drinking it.

Questions about post-workout milkshakes
Is a standard large milkshake the same as a protein-enriched shake after exercise?
No: compare the protein in the amount you will drink rather than treating bottle size as a measure of protein. Yazoo states 3.3g protein per 100ml for its Chocolate drink, Tesco Groceries lists 3.5g per 100ml for the Mars drink, and Pro Mlk states 25.7g per 330ml serving for its Chocolate Protein Shake. Which contribution suits your snack also depends on what else you plan to have.
Does ‘no added sugar’ mean the drink is sugar-free?
No. The Mars No Added Sugar flavoured milk drink contains naturally occurring sugars; Tesco Groceries lists 6.5g sugars per 100ml. Check the nutrition panel for the quantity you intend to drink.
Can I drink a 400ml bottle over two occasions?
The Yazoo and Mars 400ml examples are labelled as two 200ml servings, so you can use those serving figures when planning two portions. Follow the current bottle’s instructions for storage after opening.
Are the Yazoo, Mars or Pro Mlk examples suitable if I have a milk allergy?
No: the product information for all three lists milk. The Mars drink also lists barley. Check the ingredients and allergen statement on the current pack if you need to avoid either ingredient.
