B vitamins support normal energy function, and there’s no added sugar and zero carbs. It’s the energy category, rebuilt for people who actually care what goes into their body.

Why choose between an energy drink and a protein drink?
For too long, that's been the trade-off: reach for energy and you get a sugar-loaded can that leaves you worse off by evening; reach for protein and you get something heavy that does nothing for your focus. SPORT Rx Protein Energy Drinks refuse the compromise. Each can combines clean, plant-derived caffeine with meaningful protein, BCAAs, B vitamins and L-theanine — so you get sharp, focused energy and real recovery support in one refreshing, sugar-free drink. It's the energy category rebuilt for people who actually care what goes into their body: no junk, no crash, no choosing between performance now and how you'll feel later. Just one smarter can that works as hard as you do.
Blood Flow Support for Training Performance
Adequate blood flow during exercise underpins oxygen delivery to working muscles and the clearance of metabolic waste products — both of which directly influence how hard and for how long an athlete can train effectively. Ingredients in Protein Rx Energy are specifically selected to support healthy circulation during training, contributing to better training performance and faster intra-session recovery between sets.
Mental Focus Alongside Physical Energy
Physical energy is only part of the pre-workout equation — mental focus, motivation and the ability to maintain form and technique through fatigue are equally important performance variables. Protein Rx Energy addresses both simultaneously, with ingredients chosen specifically for their role in supporting cognitive function and alertness during training — allowing athletes to train smarter as well as harder.
Energy and protein. Pre-workout and recovery support. One drink. Zero compromise.
FAQs
Please read our FAQs page to find out more.
How is it different from a regular energy drink?
Unlike standard energy drinks, Protein Rx Energy contains a sophisticated blend of whey protein isolate, BCAAs and collagen peptides to help fuel your muscles, keep you fuller for longer, and support recovery without added sugar or artificial preservatives.
How much caffeine does it contain?
Each 300 ml can contains 160 mg of caffeine (53 mg per 100 ml), roughly equivalent to a strong cup of coffee.
When should I drink Protein Rx Energy?
Enjoy it pre-workout to boost focus and performance, midday for a clean energy lift, or post-workout to support recovery with added protein and amino acids. Always serve chilled.
Is it sugar-free?
Yes, it’s completely sugar-free and contains zero carbs, making it an ideal low-calorie option for clean energy and protein support.
What makes the protein blend special?
Protein Rx Energy uses whey protein isolate, hydrolysed collagen peptides and BCAAs to deliver a high-quality, fast-absorbing protein source — supporting muscle health, satiety and recovery.
How does it support mental performance?
The caffeine + L-theanine combination enhances focus and alertness, while B vitamins (B6 and B12) contribute to normal energy metabolism and help fight fatigue.
Are there any artificial colours, flavours or preservatives?
No. Protein Rx Energy is free from harmful or artificial ingredients, colours and preservatives.
How should I store it?
Store in a cool, dry place. Once opened, refrigerate and consume within 24 hours.

Does Protein Rx Energy help with recovery?
Definitely. With 10 g of protein per can, 2 000 mg of BCAAs, and hydrolysed collagen peptides, it helps support muscle recovery, joint health, and reduced post-workout fatigue.
Is it safe to drink more than one can a day?
We recommend limiting your intake based on your caffeine sensitivity. Each can contains 160 mg of caffeine, so factor that into your total daily caffeine consumption.
Is it suitable for low-carb or keto lifestyles?
Yes. It has zero sugar and zero carbs, making it a great fit for low-carb or ketogenic diets.
Does it contain any allergens?
Protein Rx Energy contains dairy (whey protein isolate). If you have dairy sensitivities or allergies, check with your healthcare professional before consuming.
What makes it “clean energy”?
Protein Rx Energy is designed to support performance without the harsh stimulant overload found in many traditional pre-workouts. Instead of relying on excessive synthetic stimulants and sugar crashes, it uses plant-based extracts and functional ingredients to promote smoother energy, better focus and sustained performance — helping you train hard without feeling burnt out afterwards.
