We tasted a wide range of ready to drink protein shakes to save you the work!
After a grueling workout session at your local park gym, or perhaps a challenging home workout, protein is crucial for recovery and muscle growth. But let’s be honest, sometimes whipping up a full, protein-packed meal isn’t practical when you’re on the go, juggling life, or simply don’t have the energy.
That’s where ready-to-drink protein shakes come in to their own. They’re convenient, delicious, and an efficient way to get high-quality protein into your system quickly. Perfect for that post-workout window, or even as a high-protein snack to keep you feeling full between meals. But with so many options lining the supermarket shelves and online stores, how do you choose the best one?
We’ve done the hard work for you, diving into the most popular and affordable protein shakes available in the UK in 2025. We’ve looked at protein content, ingredients, taste, and overall value to bring you our top 5 picks.
For 4 of our 5 recommended picks we’ve also included a link to a multi-buy option, which are usually better value than buying the bottles individually.

Our Top 5 Best Protein Shakes for 2025
1. UFIT High 25g Protein Shake, Chocolate

UFIT has become a staple in many UK fridges, and for good reason. Their 25g protein shake offers a fantastic balance of protein, carbohydrates, and fats, making it a well-rounded option for both post-workout recovery and a satisfying snack. The chocolate flavour is consistently praised for its smooth, rich taste that avoids the artificial aftertaste some protein drinks can have. It’s not overly thick, making it easy to drink quickly when you’re on the move after a park gym session.
- Pros: Excellent taste and texture (smooth, not chalky). Good balance of macros for recovery and satiety. Widely available in supermarkets and online. Reliable protein content.
- Cons: Slightly higher in sugar and calories compared to some ultra-low-carb options. Price per shake can add up if bought individually.
2. Grenade High Protein Shake, Fudge Brownie

Grenade burst onto the scene with their popular protein bars, and their shakes quickly followed suit, living up to the brand’s reputation for bold flavours and serious protein. The Fudge Brownie shake is a standout, offering a genuinely indulgent taste without the high sugar content often found in other “dessert” flavoured options. It’s a fantastic choice for those looking to keep their carb and sugar intake low while still getting a significant protein hit.
- Pros: Exceptionally low in sugar. Great for those on a lower-carb diet. Delicious, dessert-like flavours that curb cravings. Good protein content per serving.
- Cons: Can be slightly thicker than some other shakes, which might not suit everyone. Some find the sweetness intense due to artificial sweeteners.
3. Optimum Nutrition High Protein Shake, Vanilla

Optimum Nutrition is a powerhouse name in the supplement industry, known for its high-quality protein powders. Their ready-to-drink shakes bring that same trusted quality in a convenient format. The Vanilla flavour is a classic for a reason – it’s clean, refreshing, and versatile enough to enjoy on its own or even mixed into a quick smoothie. This shake provides a solid 25g of protein, making it an excellent choice for serious recovery after a tough session at the pull-up bars or a long run.
- Pros: Comes from a highly reputable and trusted brand. Clean, classic vanilla flavour that’s not overpowering. Good protein-to-calorie ratio. Reliable for consistent results. Packs a huge 50 grams of protein into a single 500ml bottle.
- Cons: Can sometimes be on the pricier side compared to some other options. Flavour range might be less adventurous than some competitors.
4. Pro Mlk Protein Shake, Chocolate

Pro Mlk has carved out a strong reputation for offering great value without compromising on taste or protein content. Their Chocolate protein shake is a smooth, satisfying option that delivers 25g of protein in a convenient bottle. It’s often a go-to for those looking for a reliable, everyday protein boost that’s easy on the wallet, making it a perfect fit for the budget-conscious outdoor fitness enthusiast. Its consistency is often described as similar to regular chocolate milk, making it very palatable.
- Pros: Excellent value for money, especially when bought in multipacks. Smooth, easy-to-drink texture. Good, classic chocolate flavour. Reliable protein content.
- Cons: May not be as widely available in all local supermarkets as some larger brands. Flavour range can be more limited – with only 3 flavours (chocolate, strawberry, vanilla) currently available.

5. For Goodness Shakes, Chocolate

For Goodness Shakes has been a long-standing favourite in the UK for recovery, particularly among runners and endurance athletes. While it provides 15g of protein, it also typically includes a higher carbohydrate content, making it an excellent choice for replenishing glycogen stores after longer or more intense workouts – perhaps after a full-body circuit at the park or a challenging run. The chocolate flavour is generally well-received, offering a comforting and familiar taste.
- Pros: Higher carbohydrate content ideal for post-endurance recovery. Good taste and widely available. Contains added vitamins and minerals for overall well-being.
- Cons: Has a much higher sugar content which might not be suitable for those on strict low-carb diets. Can be slightly more expensive per shake.
Your Buying Guide: Choosing the Best Protein Shake for YOU
With so many great options, how do you pick the perfect protein shake for your needs? Consider these factors before you buy:
1. Protein Content & Source
Most ready-to-drink shakes offer 20-30g of protein per serving, which is a great amount for muscle repair and growth. Check the source – most will be whey or casein (milk-based proteins), which are excellent for muscle synthesis. If you’re plant-based, look for shakes made from pea, soy, or a blend of plant proteins.
2. Calories & Macros (Carbs & Fats)
Your overall diet and goals play a big role here. If you’re aiming for fat loss, you might prefer a lower-calorie, lower-sugar option (like Grenade). If you’ve just completed a long, intense workout (like a long run or a big circuit at the park), a shake with a few more carbs (like For Goodness Shakes) can be beneficial for replenishing energy stores.
3. Sugar Content
While some sugar can be useful post-workout, many prefer to limit it. Check the nutrition label. Many brands use artificial sweeteners to keep sugar low, which is fine for most, but some individuals prefer to avoid them.
4. Taste & Texture
This is highly personal! What one person loves, another might dislike. Look for reviews on taste and texture. Some prefer thicker, milkier shakes, while others want something lighter. Starting with a single bottle before buying a multipack can be a good idea to find your favourite.
5. Price & Value
Ready-to-drink shakes are more expensive than protein powder, but the convenience often justifies the cost. Look for multipacks via the links in this article, as they usually offer much better value per shake.
6. Dietary Needs & Allergens
Always check for allergens like dairy or soy if you have sensitivities. Some brands offer lactose-free or plant-based options.
