Pre-workouts are one of the most hyped supplement categories. Walk into any gym and you will see someone sipping a neon-coloured drink from their shaker, swearing it makes them train twice as hard. But do you actually need one?
I will be upfront — I do not use pre-workout regularly. A strong coffee does the job for me 90% of the time. But I have tried several over the years and I understand why people love them. Here is an honest guide to the best options in the UK, plus whether you should even bother.
Do You Even Need a Pre-Workout? (Honest Take)
Before spending £20-30 on a tub of pre-workout, consider this:
A cup of coffee gives you:
- 80-100mg caffeine (the main active ingredient in most pre-workouts)
- Proven focus and energy boost
- Costs roughly 10p per cup
A pre-workout gives you:
- 150-300mg+ caffeine (much stronger dose)
- Additional ingredients like beta-alanine, citrulline, and creatine
- Costs roughly £0.50-1.00 per serving
If coffee gets you through your workouts fine, you do not need pre-workout. Save your money. But if you train very early in the morning, have intense sessions, or just need that extra kick on heavy days — a good pre-workout can genuinely help.
What to Look For in a Pre-Workout
Most pre-workouts contain the same core ingredients. Here is what actually matters at what doses:
| Ingredient | What It Does | Effective Dose | Watch Out For |
|---|---|---|---|
| Caffeine | Energy, focus, performance | 150-300mg | Too much = jitters, anxiety, crash |
| Citrulline Malate | Muscle pumps, blood flow, endurance | 6-8g | Many products underdose this |
| Beta-Alanine | Endurance, buffers lactic acid | 3.2-6.4g | Causes tingling sensation (harmless) |
| Creatine | Strength and power | 3-5g | Unnecessary if you already take creatine daily |
| L-Theanine | Smooth focus without jitters | 100-200mg | Not all products include this |
| Betaine | Power output, endurance | 2.5g | Newer ingredient, decent evidence |
Red flags to avoid:
- “Proprietary blends” — this means they are hiding the doses. If they do not tell you how much of each ingredient, they are probably underdosing everything
- More than 350mg caffeine — this is excessive for most people and increases risk of side effects
- Artificial colours and unnecessary fillers
- Products that list 20+ ingredients — usually means tiny ineffective doses of each
Best Pre-Workout Supplements UK
1. Applied Nutrition ABE (All Black Everything) — Best Overall
Overview: ABE is one of the most popular pre-workouts in the UK and for good reason. It has properly dosed ingredients, great flavours, and a strong but not overwhelming energy kick. Applied Nutrition is a brand I trust — their whey protein is one of my favourites too.
Key Details:

2. Gorilla Mode Pre-Workout — Best for Serious Lifters
Overview: Created by fitness YouTuber Derek from More Plates More Dates, Gorilla Mode has become hugely popular for its fully transparent, heavily dosed formula. This is not a pre-workout for beginners — it is for people who want maximum performance.
Key Details:
- Caffeine: 175mg per scoop (350mg at full 2-scoop serving)
- Citrulline: 4.5g per scoop (9g at full serving)
- Creatine: 2.5g per scoop

3. Myprotein THE Pre-Workout — Best Budget
Overview: MyProtein offers a decent pre-workout at a typical MyProtein price — affordable, especially during their frequent sales. Not the most exciting formula but it gets the job done.
Key Details:
- Caffeine: 175mg
- Citrulline: included
- Beta-Alanine: included
- Servings: 30
- Price: Around £15-20 (cheaper on sale)

4. Warrior RAGE — Best UK Brand Pre-Workout
Overview: Warrior is a well-known UK supplement brand and RAGE is their flagship pre-workout. Known for strong energy and good flavours. Popular in UK gyms.
Key Details:
- Strong caffeine content
- Good flavour range
- UK brand, widely available
- Price: Around £18-25
5. The Free Alternative: Coffee + Creatine
This is what I personally use most of the time and I am including it because honesty matters more than affiliate commissions.
The stack:
- One strong black coffee (80-100mg caffeine) — 10p
- 5g creatine monohydrate mixed in water — 5p
- Total cost: 15p per “serving”
This gives you caffeine for energy and creatine for strength. You miss out on citrulline (pumps) and beta-alanine (endurance), but for most training sessions, coffee and creatine is genuinely all you need. I save pre-workout for the occasional heavy session or days when I am really dragging.

Pre-Workout Side Effects to Know About
Beta-Alanine Tingling
That itchy, tingling sensation on your skin (usually face and hands) after taking pre-workout? That is beta-alanine. It is called paraesthesia and it is completely harmless. It goes away after 15-30 minutes. Some people love it because it makes them feel like the pre-workout is “working.” Others hate it. If you hate it, look for a product without beta-alanine.
Caffeine Sensitivity
If you are sensitive to caffeine, start with half a scoop. Most pre-workouts contain 150-300mg of caffeine — equivalent to 2-3 cups of coffee in one go. Taking it too late in the day (after 4-5pm) can seriously disrupt your sleep.
Crash
High-caffeine pre-workouts can cause an energy crash 3-4 hours later. Products with L-Theanine tend to produce smoother energy without the crash.
Dependency
If you take pre-workout every single session, your body builds tolerance to caffeine and it stops working as well. I recommend using pre-workout only 2-3 times per week on your hardest sessions, and using coffee or nothing on lighter days.
Frequently Asked Questions
Can I take pre-workout every day?
You can, but I would not recommend it. Your caffeine tolerance will build quickly, forcing you to take more for the same effect. Use it strategically on your hardest training days.
Is pre-workout safe?
Reputable brands with transparent labels are generally safe for healthy adults. However, people with heart conditions, high blood pressure, or caffeine sensitivity should consult a doctor first. Do not exceed the recommended serving size.
Should I take pre-workout on an empty stomach?
It absorbs faster on an empty stomach but can cause nausea for some people. If you get stomach discomfort, have a small snack (banana, toast) 30-60 minutes before.
Pre-workout vs energy drinks — which is better for the gym?
Pre-workout is better because it contains performance-specific ingredients (citrulline, beta-alanine, creatine) that energy drinks lack. Energy drinks are basically just caffeine and sugar. If you are going to spend money on a gym boost, a proper pre-workout is the smarter choice.
I am a beginner — should I take pre-workout?
No. Beginners should focus on building consistent training habits, dialling in their diet, and taking the basics (protein and creatine). Pre-workout is an advanced supplement for when your training intensity demands it. Read my guide on which supplements you actually need.
My Final Take
Pre-workout is not essential. Coffee and creatine will get most people through most sessions just fine. But if you want that extra edge on heavy days, Applied Nutrition ABE is the best option in the UK — properly dosed, great tasting, and from a brand I trust.
Just do not become dependent on it. Save it for when you really need it.
