One of the only protein powders by C4, this leans heavily into indulgence with its Reese’s-inspired peanut butter and chocolate flavour. It delivers a thick, milkshake-like consistency even when mixed with water, making it one of the most dessert-like options available.

Beyond taste, it offers a high protein content per serving and is designed with performance in mind, supporting recovery and muscle growth. It has no added sugars, which is a notable benefit for those tracking their intake closely.

Protein Works Whey Protein 360 - PLATINUM Innovation 600g RRP £41.99

Cost per serving: ~£2.47
Serving: 35g (17 servings)
Calories: 127kcals

This is a quality, all-in-one formula combining fast and slow-release proteins designed for sustained nutrient delivery throughout the day. Added vitamins and digestive enzymes make it more functional, elevating it above a standard whey protein.

The flavour is subtle and neutral, which works well for mixing into recipes or smoothies rather than drinking on its own. Its versatility and nutritional profile are strong, but the higher price point may be a barrier.

Why use protein powder?

Protein supplements are great for active Britons, gym-goers, athletes, and anyone struggling to meet daily protein needs through whole foods alone. This can become particularly important with age as a way of maintaining strength and mobility, as muscle mass naturally declines over the years.

They can support muscle growth, repair, and recovery, especially after exercises like strength training. Indeed, A meta-analysis in the British Journal of Sports Medicine study found that protein supplementation had a significant impact on increasing muscle size and strength when combined with resistance training.

Incorporating protein powders into your diet can also help with weight management as the macronutrient promotes feelings of fullness and helps maintain lean muscle while dieting.

What's more, it is a convenient, quick option for busy lifestyles and can support overall health, including bone strength and metabolic function.
