Formula Breakdown
NooLVL® - 1,600mg. NooLVL® is a patented ingredient, naturally its found in OPTIMISE. It supports cognitive performance and energy in gamers.
NooLVL® is the first dietary ingredient of its kind to be clinically studied in eSports athletes to significantly improve visual attention, accuracy and reaction time. First timer or seasoned gamer you'll be levelling up in no time!
N-acetyl-L-tyrosine (NALT) - 1,500mg. Ensure you're dialled in with this large dose of N-acetyl-L-tyrosine (NALT). It ensures your brain has the necessary "reserves" to synthesise catecholamines (e.g., dopamine and adrenaline). These neurotransmitters are crucial for wakefulness, attention, and motivation during an intense gaming competition.
Choline Bitartrate - 1,000mg. Choline bitartrate is a combination of choline and tartaric acid. It is primarily used to support the production of acetylcholine and phosphatidylcholine. Acetylcholine is a key neurotransmitter in the brain, associated with cognitive function.
CDP-Choline - 250mg. Using CDP-Choline helps boost cognition, increases brain energy, can improve learning and memory. For the serious gamer, this means quick thinking and mental processing, as well as better memory consolidation and retrieval.
Caffeine Anhydrous - 100mg. Just the right amount to give you a good caffeine kick without the crash of traditional energy products.
TeaCrine® - 100mg. TeaCrine® is a patented compound that delivers energy and activates dopamine receptors for improved motivation.
INFINERGY™ (Di-Caffeine Malate) - 100mg. Infinergy™ serves as a form of extended-release caffeine. Di-caffeine malate is a perfect carry on after that inital caffeine hit starts to wear off. Simply put, stand-alone caffeine only goes so far for kicking your brain into gear and keeping you alert.
AstraGin® - 50mg. AstraGin® works to help improve your ability to absorb key ingredients, essentially it ensures you're getting maximum benefit from everything we've put into this market-leading formula.

Another top product guys! Blue razz taste is fantastic and gives me a nice afternoon pick me up!
Tastes great and does exactly what it says. I was really impressed with how well it dissolved.
Strawberry and lime flavour is really refreshing
Use this for when working from home to stay concentrated throughout meetings and also when you need to purge for a session
Great product!!
I have used this for a week now and I feel sharp as alert to take on my working day.
Well worth purchasing if you need to focus during your day

Great product!!
Took this 15 mins before going into an assessment centre for a new job. Had carried out plenty of research prior to purchase. I was not disappointed at all! Came away feeling that I'd performed the best I could have done. Received a phone call later to say I'd been successful. What an absolute belter of a product. Thanks to Alex and his incredible team.
Brilliant customer service, great quality and supporting military veterans.
As an avid fan of Youtuber Stephen Howson, I’ve watched his health journey whilst using your products as a positive substitute for his reliance on store bought energy drinks.
As someone that was drinking 4-5 monster cans a day to facilitate my 60+ hour a week work schedule (& experiencing major crashes as a result), I made the switch on his recommendations, after seeing his results
After 2 months of use, in conjunction with other positive life changes, I have more energy & alertness whilst experiencing no crashes in energy. On busy days, I may have up to 2 servings throughout a 12+ hour working day, but I have also developed a positive habit of drinking more water in general, which has been key to my great start to 2025.
Huge props to the Combat Fuel team

Wow, just wow! I’ll admit, I was initially so skeptical about Optimise, but now I’m absolutely blown away by how incredible it is! I’m not a gamer, but I do struggle with concentration during everyday tasks, and this product has been a game-changer. It gave me laser-sharp focus—even for something as mundane as cleaning the entire house!
I tried it this morning after breakfast before hitting the gym, and I absolutely crushed my workout. It gave me unparalleled energy and focus without any of the side effects I usually experience with pre-workouts. Optimise has officially become a staple in my daily routine, and I recommend it to everyone I know. Whether you’re tackling chores, working out, or just trying to concentrate better, this product is an absolute must-try. Total life-changer! Well done on producing something so good Combat Fuel.
Excellent taste
Turned to Combat to help reduce my red bull intake. Amazing substitution, not too potent and gives you the perfect little boost you need
I have been obsessed with using this for well over a year now.. soon as I started using it I’ve never gone back and always rave about it. Flavours are STUNNING (tastes like slush puppy) and I enjoy the vibe whilst training with it!
No Marketing BS and Clear Clean Ingredients. Perhaps the best I've ever seen
I use this for BJJ, feels like it gives me that extra focus after a long day at work.
I'm not a gamer, but I use Optimise for intense work meetings, where I need the extra focus, and recently for sitting an exam. It really does work, and doesn't give me the jitters, like caffeine does. It also doesn't have that horrible crash that sugar does. Highly recommneded!
I started using Optimise recently as I noticed with long periods of working from home my attention span has dropped a lot, this has allowed me to get that extra focus back into my routine and keep on top of work! Also the protein clusters that were thrown into the order for free were incredible!
Tried the sample pack and all the flavours are great. This used with the pumped-up gives you all you need for an insane workout and it's a great alternative to pre workout.
Absolute fantastic product
Tastes nice
Gives energy focus and motivation at work
Lasts through the day or night -great for shift workers
Never had a product like it and super value for money
Will be purchasing more as my shifts are not the same without it
Maintains your stamina, without any of the downs that caffeine gives - go ahead try it and be the best version of you
This product tastes great and delivers. Will definitely buy more. Highly recommended.
Definitely gives me the edge working on my PC or even gaming and all the flavours taste great! Highly recommend
Having tried all the flavours I'm hooked! Definitely gets me going while I'm gaming!
Optimise - Blue Razz, fantastic stuff. Flavours are spot on without being overly sour. Texture of the drink is very smooth, although I’ve found it helps to weigh the 5g on the scoop - as a full level scoop is 7g and the result is a chalky texture. Once I figured that out I add a little more water, stir it with a spoon before shaking it up.
Keeps you awake, alert, it’s a refreshing drink without the draw back of a sugar high - and for someone with ADHD, it actually works rather than putting me to sleep!
Normally avoid these types of energy drinks because they taste powdery but this brand is like no other - no powdery taste and gave me an energy boost without the shakes! Tastes dreamy! Absolutely Love the strawberry and lime! Highly recommended!
Two of my favourite things are playing COD and going out with mates in our cars. I feel alert and well focused without having to have an energy drink every few hours!
Unbelievable product.
I have long been a fan of nootropic style supplements. Optimise does everything I want it to and more, helping me deliver more focus and drive to a busy work/life schedule.
I was amazed as well that even 8 hours after using the product I could still feel that focus and drive when training and teaching BJJ.
