Everything you need to know about gym supplements — what they do, who they're for, and how to choose the right ones for your goals.
Protein Powder
The foundation of any supplement stack. Protein supports muscle growth, repair, and recovery after training. Ideal for anyone who trains regularly and struggles to hit their daily protein targets through food alone.
- Builds and repairs muscle tissue
- Supports recovery after training
- Convenient post-workout nutrition
- Available in whey, casein & vegan
Creatine
One of the most researched supplements in sports science. Creatine helps your muscles produce energy during heavy lifting and high-intensity exercise. A proven staple for anyone looking to build strength and muscle.
- Increases strength and power output
- Supports lean muscle growth
- Improves high-intensity performance
- Safe and well-researched
Pre-Workout
Designed to be taken 20–30 minutes before training. Pre-workout supplements boost energy, focus and endurance so you can train harder for longer. Best for athletes who want to get more from every session.
- Boosts energy and mental focus
- Increases training endurance
- Enhances muscle pumps
- Contains caffeine, beta-alanine & more
BCAAs & Amino Acids
Branched-chain amino acids are the building blocks of muscle. BCAAs can be taken during training to reduce muscle breakdown, decrease soreness and speed up recovery between sessions.
- Reduces muscle soreness (DOMS)
- Prevents muscle breakdown
- Supports muscle protein synthesis
- Great during fasted training
Weight Gainers
Mass gainers combine protein and carbohydrates in a single shake, making it easier to hit a caloric surplus for muscle building. Ideal for hardgainers or anyone struggling to eat enough calories to grow.
- High calorie formula for muscle gain
- Combines protein and carbohydrates
- Convenient way to hit calorie goals
- Ideal for hardgainers
Fat Burners
Thermogenic fat burners support weight management by increasing metabolism and energy expenditure. Best used alongside a calorie-controlled diet and regular training — not as a replacement for either.
- Boosts metabolic rate
- Supports energy during a calorie deficit
- Reduces appetite
- Works best alongside diet & training

Common Questions
Frequently Asked Questions
What gym supplements should I take as a beginner?
Start with the basics: a quality protein powder and creatine monohydrate. These two supplements are the most researched and proven for muscle growth and performance. Once you've established a consistent routine, you can consider adding a pre-workout or BCAAs.
Are gym supplements safe?
Quality gym supplements from reputable UK brands like Gym High are safe when used as directed. We use clear ingredient labels with defined doses so you always know exactly what you're taking. As with any supplement, consult a healthcare professional if you have any pre-existing conditions or are taking medication.
When is the best time to take protein powder?
Whey protein is fast-digesting and works well post-workout to kickstart muscle recovery. However, the most important thing is hitting your daily protein target — the exact timing is secondary. Protein shakes can be taken any time of day as a convenient way to boost your intake.
Do I need supplements to build muscle?
No — supplements are not essential. Consistent training, adequate protein intake and enough sleep are far more important. However, supplements can make it easier to hit your nutritional targets, especially protein. Think of them as a convenient tool, not a shortcut.
