Whether you’re lifting heavy weights, running long distances, or engaging in high-intensity interval training, post-workout nutrition is crucial for reducing muscle soreness, replenishing nutrients, and accelerating recovery. Maximising recovery after a workout is just as important as the workout itself.
But with so many options available, what are the best supplements to speed up recovery? Here are the top post-workout supplements to help you recover faster and get back to training stronger.
1. Whey Protein – The Muscle Repair Essential
Protein is the building block of muscle recovery, and whey protein is one of the most effective options due to its fast absorption rate and high leucine content. It helps promote muscle protein synthesis (MPS), which is essential for muscle repair and growth.
👉 Best for: Strength training, muscle building, and overall recovery.
👉 Recommended Product: Optimum Nutrition Gold Standard Whey
Optimum Nutrition Gold Standard Whey
- High-Quality Protein: 24g protein, 5g BCAAs, and 4g glutamine per serving for muscle recovery.
- Fast & Versatile: Whey isolate blends easily into shakes, oatmeal, and more.
- Trusted & Safe: Gluten-free, instantized, and tested for banned substances.
2. Casein Protein – The Slow-Releasing Recovery Aid
Unlike whey, casein protein digests slowly, providing a steady release of amino acids for muscle recovery over several hours. This type of protein is an excellent pre-bedtime supplement aiding overnight recovery.
👉 Best for: Long-term muscle repair and overnight recovery.
👉 Recommended Product: Lean Dessert by Genetix Nutrition Chef Series

- Macro-Friendly & Low-Lactose: Provides a high-protein, low-calorie dessert option with added fiber, MCT oil, and glutamine to support digestion, brain function, and overall health.
3. BCAAs – Reduce Muscle Soreness & Fatigue
Branched-chain amino Acids (BCAAs)—leucine, isoleucine, and valine—are essential for reducing muscle breakdown and improving endurance. BCAAs are particularly useful when taken post-workout to decrease delayed onset muscle soreness (DOMS).
👉 Best for: Reducing muscle soreness and improving recovery speed.
👉 Recommended Product: Amino Recovery by Musashi

4. Creatine Monohydrate – Replenish Energy Stores
Creatine is not just for strength and power—it's also a recovery powerhouse. Post-workout creatine supplementation helps restore ATP levels, ensuring muscles have the energy needed for the next workout. It also aids in reducing inflammation and muscle damage.
👉 Best for: Strength athletes, powerlifters, and high-intensity trainers.
👉 Recommended Product: 100% Creatine Monohydrate by Genetix Nutrition
100% Pure Creatine by Genetix Nutrition Essentials

- Supports Lean Muscle Growth: Aids in building high-quality muscle while promoting overall body composition goals.
5. L-Glutamine – The Recovery Booster
L-glutamine is an amino acid that plays a key role in muscle repair and immune function. After intense training, glutamine levels drop, which can increase muscle breakdown. Supplementing with glutamine helps accelerate recovery and reduce muscle fatigue.
👉 Best for: Athletes looking for faster muscle repair and immune support.
👉 Recommended Product: 100% L-Glutamine by Switch Nutrition
100% Pure L-Arginine by Switch Nutrition

6. Electrolytes – Stay Hydrated, Stay Recovered
Sweating during a workout leads to the loss of essential electrolytes, which can cause cramps, dehydration, and fatigue. Replenishing electrolytes post-workout helps restore hydration levels and support muscle function.
👉 Best for: Endurance athletes and high-intensity trainers.
👉 Recommended Product: Electrolyte + Hydration by Body Science
Electrolyte + Hydration by Body Science

7. Omega-3 Fatty Acids – Reduce Inflammation & Joint Pain
Post-workout inflammation can slow down recovery. Omega-3 fatty acids, found in fish oil supplements, help reduce inflammation, promote joint health, and aid muscle recovery.
👉 Best for: Reducing muscle soreness and improving overall recovery.
👉 Recommended Product: Ultra Omega by PILLAR Performance
