If reusable glass is a priority, The Modern Milkman’s Chocolate Protein Shake is a relevant option: the brand lists 40g protein per pint and says it collects and refills its glass bottles, but you need to check postcode coverage and be able to return the empties. If the bottle-return system does not suit you, compare ready-to-drink alternatives by protein, sugars and energy for the whole serving rather than assuming that every milkshake makes the same contribution to your diet.
The useful distinction is whether reusable glass is a firm requirement or one preference among serving size, nutrition and convenience.
The Modern Milkman’s returnable-bottle service is worth considering if you want a ready-to-drink protein shake in glass. Check that your postcode is served and that rinsing and leaving bottles out for collection fits your routine.
If a portable, pre-mixed drink matters more than glass, compare the protein, sugars and energy in the amount you would drink. A 330ml bottle and a 500ml bottle are different serving sizes, even when both are marketed as protein shakes.
University Hospitals Sussex NHS Foundation Trust notes that protein needs differ for people with chronic kidney disease according to their treatment. If you have a prescribed target, check the drink’s label against the advice from your renal team or dietitian rather than choosing by the front-of-pack wording alone.
Decide first whether the glass-bottle return system works for you; then compare nutrition using the complete serving you expect to drink.
Consider it when: A returnable glass bottle and doorstep delivery matter enough to check The Modern Milkman’s postcode coverage.
Trade-off: The brand’s system requires local service and rinsed empties left out for collection.
Consider them when: A labelled, pre-mixed serving matters more to you than a reusable-glass return system.
Trade-off: A conventional bottle does not meet a firm reusable-glass requirement; check each product’s packaging rather than assuming it has a return scheme.
| Priority | What to check | Your needs |
|---|---|---|
| Protein per serving | Compare the amount in the whole bottle or pint you intend to drink. The Modern Milkman lists 40g per pint; Optimum Nutrition lists 25g per 330ml; Tesco lists 50g per 500ml for UFIT Pro50 Strawberry. | I want to know what one drink contributes to my own protein target, not just what its front label calls it. |
| Glass and collection | The Modern Milkman says its glass bottles are collected, cleaned and refilled. Check postcode coverage, delivery days and what you need to do with empties. | Reusable glass matters to me, but the collection routine also has to work at my address. |
| Sugars and energy | Read both figures for the full serving: Optimum Nutrition lists 13g sugars and 185kcal per 330ml; Tesco lists 18g sugars and 280kcal per 500ml for UFIT Pro50 Strawberry. Compare like-sized servings if volume affects your choice. | I would rather see the sugars and energy in the amount I will actually drink than rely on a no-added-sugar claim. |
| Ingredients and dietary needs | Check the current ingredient and allergen declaration; Tesco lists milk as an allergen for Yazoo Chocolate. If you follow a prescribed protein target, compare the labelled amount with your individual advice. | I need the drink’s ingredients and serving size to fit my circumstances, particularly if I must avoid milk or follow a prescribed diet. |
Tesco lists 3.2g protein per 100ml for Yazoo Chocolate, while Optimum Nutrition lists 25g in a 330ml High Protein Shake. Those figures use different serving bases and do not describe interchangeable drinks.
Check protein for the amount you plan to drink, then read sugars and energy on the same serving basis.
Tesco’s label for UFIT Pro50 Strawberry says no added sugar but still lists 18g total sugars per 500ml bottle.
Use the total sugars line and the stated serving size when comparing bottles.
The Modern Milkman asks customers to check their postcode, and its reuse system involves scheduled delivery and collection of empties.
Confirm service at your address and decide whether you can rinse and leave bottles out for collection before choosing it as a regular option.
University Hospitals Sussex NHS Foundation Trust explains that protein needs can differ across kidney treatments; the amount in one shake may therefore matter differently to someone with an individual target.
If you have a prescribed protein intake, discuss the labelled serving with your renal team or dietitian.
These product-line examples show different serving and packaging arrangements; a brand’s inclusion does not mean every one of its drinks has the same characteristics.
Its Chocolate Protein Shake is the reusable-glass delivery option in this comparison.
Its 330ml High Protein Shake offers a smaller ready-to-drink serving to compare with larger bottles.
UFIT Pro50 Strawberry is a 500ml ready-to-drink option with a different serving size from the glass-bottle shake.
Yazoo Chocolate 400ml is a flavoured milk drink to compare by its nutrition panel rather than its category name.
These flavoured protein shakes offer ready-to-drink alternatives to consider when reusable glass is a preference rather than a firm requirement. If glass is essential, confirm each pack’s material and any return arrangement before buying.

A ready-to-drink chocolate option for comparing nutrition by the 500ml bottle. Check the current label for protein, sugars, energy and milk ingredients; confirm the bottle material and any return arrangement if reusable glass matters to you.

This ready-to-drink strawberry option comes in a smaller stated bottle size than the Double Chocolate variant above. Compare the nutrition for its own 330ml serving, and check the pack for milk ingredients, bottle material and any return instructions.

A ready-to-drink vanilla option with a 250ml stated serving. Read the current nutrition and allergen label for that serving, and check the container and any return arrangement before choosing it for a reusable-glass preference.
The Modern Milkman lists 40g protein per pint for its Chocolate Protein Shake and says the glass bottles are collected, cleaned and refilled. Enter your postcode to check whether its delivery service reaches your address.
The Modern Milkman asks customers to rinse the empty pint-sized glass bottles and leave them on the doorstep for collection. If that routine is impractical at your address, its return-and-reuse service may not suit you.
Start with the amount in the serving you expect to drink, then use per-100ml figures when comparing different bottle sizes on the same basis. Optimum Nutrition lists 25g per 330ml bottle, The Modern Milkman lists 40g per pint, and Tesco lists 50g per 500ml bottle for UFIT Pro50 Strawberry.
Check the current ingredient and allergen declaration on each drink rather than assuming that a protein shake is suitable. Tesco explicitly lists milk as an allergen for Yazoo Chocolate; formulations and labels should be checked for the specific product you intend to buy.
Use your individual advice when assessing how a whole bottle fits your intake. University Hospitals Sussex NHS Foundation Trust notes that protein needs can differ across kidney treatments, so discuss a drink’s labelled serving with your renal team or dietitian if this applies to you.
