The Top 10 Supplements for Gym, Sport & Active Lifestyles
The Top 10 Supplements for Gym, Sport & Active Lifestyles – What to Take, Why to Take It & When to Take It
Whether you're lifting weights, running, cycling, playing football, training for a marathon or simply living a more active lifestyle, your body needs the right fuel to perform at its best.
Training hard is only part of the equation. Recovery, muscle repair, energy production and overall health all play a huge role in helping you reach your goals.
Supplements aren't magic—they're designed to support a healthy diet and consistent training programme. Think of them as giving your body the nutritional support it needs to perform, recover and improve.
Here are our Top 10 supplements for active people, why they're beneficial, and the best time to take them.
It's recommended that men drink 13 cups (about 3 liters) of water each day.
1. Protein Powder – The Foundation of Muscle Recovery
If there is one supplement that almost every active person should consider, it's protein powder.
Every workout causes tiny tears in your muscle fibres. Protein provides the amino acids your body needs to repair those fibres, helping muscles recover stronger than before.
Benefits
• Supports muscle growth
• Helps muscle recovery
• Reduces post-workout soreness
• Helps maintain lean muscle while losing fat
• Convenient way to increase daily protein intake
Best Sources
Whey Protein
Whey Isolate
Casein Protein
Plant-Based Protein
Best Time to Take
★★★★★ Immediately after training
Also useful:
Breakfast
Between meals
Before bed (Casein)
2. Creatine – One of the Most Researched Sports Supplements
Creatine has been studied for decades and remains one of the most effective supplements available.
It increases the body's stored phosphocreatine, allowing muscles to produce energy more quickly during explosive exercise.
Benefits
• Increased strength
• Improved power output
• Better gym performance
• Supports muscle growth
• May improve recovery
Best Time
Any time of day.
Many people prefer taking it immediately after training with their protein shake.
Recommended intake is generally around 3–5g daily, taken consistently.
3. BCAA (Branched Chain Amino Acids)
BCAAs contain three essential amino acids:
Leucine
Isoleucine
Valine
These amino acids help stimulate muscle protein synthesis and may reduce muscle breakdown during prolonged or intense exercise.
Benefits
• Supports recovery
• Helps reduce muscle soreness
• May reduce fatigue during long workouts
• Supports muscle preservation when training fasted
Best Time
Before training
During training
Immediately after training
Especially useful during longer endurance sessions.
4. Omega-3 Fish Oil
Omega-3 is often overlooked, yet it's one of the best supplements for overall health.
Healthy joints, heart health and brain function all benefit from adequate Omega-3 intake.
Benefits
• Supports heart health
• Supports brain function
• Helps maintain healthy joints
• May assist recovery from exercise
• Supports healthy inflammation response
Best Time
Take with meals containing healthy fats.
Morning or evening both work well.
5. Magnesium – The Recovery Mineral
Many active people don't consume enough magnesium.
Since magnesium is involved in hundreds of processes throughout the body, it plays an important role in recovery and muscle function.
Benefits
• Supports normal muscle function
• Helps reduce tiredness and fatigue
• Supports sleep quality
• Supports nerve function
• Helps normal energy production
Best Time
Evening or before bed.
Many people find it fits well into a bedtime routine.
6. Zinc – Small Mineral, Big Benefits
Zinc supports normal immune function and contributes to normal protein synthesis.
Heavy training can increase nutritional demands, making zinc an important nutrient to include in your diet.
Benefits
• Supports immune health
• Contributes to normal protein synthesis
• Supports recovery
• Helps maintain healthy testosterone levels within the normal range
Best Time
Evening with food.
Avoid taking it alongside large amounts of calcium or iron supplements where possible.
7. Vitamin B12 – Natural Energy Support
Vitamin B12 plays an important role in energy metabolism and red blood cell formation.
It's particularly important for vegetarians and vegans, who may have lower dietary intake.
Benefits
• Supports normal energy release
• Helps reduce tiredness
• Supports nervous system function
• Helps oxygen transport through healthy red blood cells
Best Time
Morning
Taking B12 early in the day suits many people's routines.
8. Multivitamins – Your Daily Nutritional Insurance
No diet is perfect.
A good quality multivitamin helps fill nutritional gaps, particularly during busy periods or intense training phases.
Benefits
• Supports immune function
• Supports energy production
• Provides essential vitamins and minerals
• Helps overall wellbeing
Best Time
Breakfast
Taking a multivitamin with food may improve tolerance and absorption.
9. Beta-Alanine – Built for High-Intensity Training
Beta-Alanine became extremely popular with athletes for good reason.
It increases muscle carnosine levels, helping buffer acid build-up during intense exercise.
Many people notice a harmless tingling sensation shortly after taking it.
Benefits
• Supports muscular endurance
• Helps delay muscle fatigue
• Ideal for HIIT workouts
• Useful for CrossFit, football, rugby and sprint training
• Supports higher training volume
Best Time
30–60 minutes before training.
Daily use is more important than exact timing, as benefits build over time.
10. Water – The Most Important Performance Supplement
Technically not a supplement—but probably the most important item on this list.
Even mild dehydration can reduce physical performance.
Muscles are largely made up of water, and proper hydration supports everything from endurance to concentration.
Benefits
• Regulates body temperature
• Supports muscle performance
• Helps nutrient transport
• Supports recovery
• Helps prevent dehydration
Best Time
All day.
Aim to stay hydrated before, during and after exercise.
Bonus: Glucose – Fuel for Endurance Exercise
Glucose provides a rapid source of carbohydrate energy.
While not necessary for every workout, it can be useful during prolonged endurance activities such as long-distance cycling, running or team sports.
Best For
Marathon runners
Cyclists
Footballers
Rugby players
Long gym sessions
Best Time
Before or during extended exercise lasting more than an hour.
