Over the last 18 years of training, coaching, and experimenting with my own performance, I've seen the best and worst of the supplement world. When I first started, I was overwhelmed by the noise - endless products, unnecessarily large tubs, flashy marketing, and promises that didn't always deliver.
Over time, I learned to cut through it. I stopped chasing hype and started looking for effective ingredients backed by science - supplements that actually supported strength, endurance, recovery, and body composition. That's why aligning with Musashi was easy for me: simple, effective, evidence-based formulas that do exactly what they claim to.
In this article, I'll share the best supplements for specific training goals - matched with Musashi products I trust. If you're serious about getting results, this is where to start.
1. Build Strength & Muscle
Key Supplements: Creatine, Protein and ZMA
Creatine
Creatine is one of the most studied sports supplements, with strong evidence supporting its ability to enhance strength, power, and muscle mass. Creatine increases the availability of phosphocreatine in muscles, allowing you to regenerate ATP - the primary energy source for explosive movements - faster during high-intensity exercise. PMID: 28615996
Best for: Heavy lifting, sprinting, short bursts of explosive effort.
Protein
Protein is essential for muscle repair and growth. Numerous studies show that consuming high-quality protein around training can stimulate muscle protein synthesis - a key process for muscle growth, maintenance, and repair. PMID: 22932282
Best for: Building lean mass, enhancing recovery and maintaining strength during cuts.
ZMA (Zinc, Magnesium Aspartate & Vitamin B6)
ZMA is a combination of zinc, magnesium, and vitamin B6 - nutrients that play key roles in muscle recovery, hormone production, and sleep quality. Zinc supports testosterone levels and immune function, while magnesium aids in muscle relaxation and nervous system regulation. Together, they're commonly used by athletes to optimise recovery, especially during heavy training phases. PMID: 18500945
Best for: Strength and hypertrophy phases, athletes looking to improve sleep quality, reduce muscle cramps, and support hormonal balance during intense training blocks.
2. Fat Loss
Key Supplements: Carnitine and Protein
Carnitine
Carnitine is a compound that plays a key role in fat metabolism by transporting long-chain fatty acids into the mitochondria, where they're burned for energy.
Best for: Endurance athletes or individuals in fat-loss phases aiming to increase fat utilisation, improve recovery, and reduce exercise-induced muscle soreness.
Protein
Protein isn't just for building muscle. Higher protein intake increases satiety, supports lean mass retention during a calorie deficit and raises the thermic effect of food (your body burns more calories digesting it). Adding shakes are a great way to top up meals or replace snacks. PMID: 23097268
Best for: Preserving muscle while losing fat and managing hunger.
3. Endurance
Key Supplements: Carbohydrates, Electrolytes and Beta Alanine
Carbohydrates
Carbs are the primary fuel for endurance training. Supplementing with easily digestible carbs before, during, and after training preserves glycogen stores and enhances performance. Options like gels, drinks and powders are easily digestible forms for rapid absorption. PMCID: PMC9734239
Best for: long runs, cycling and team sports.
Electrolytes
Sweating depletes electrolytes (especially sodium, potassium, and magnesium), crucial for hydration, muscle function, and preventing cramps. Preloading electrolytes before a heavy sweat session or hot day is an effective way to stay hydrated. PMCID: PMC5790864
Best for: Endurance athletes, hot climates and long sessions.
Beta-Alanine
Beta-alanine acts as a buffer against acid build-up in muscles during high-intensity exercise, delaying fatigue and allowing you to push harder for longer. PMID: 23075550
Best for: High-intensity endurance events (e.g. rowing, running intervals, cycling), hybrid training formats like CrossFit, Hyrox, and functional fitness, and strength endurance blocks.
4. Focus
Key Supplements: Caffeine + Theanine and L-Tyrosine
Caffeine + Theanine
Combining caffeine with L-theanine (an amino acid found in tea) delivers the best of both worlds: enhanced alertness and reaction time without the "jittery" side effects. PMID: 24946991
Best for: Staying locked in during heavy training or competitions.
L-Tyrosine
L-tyrosine supports cognitive function under stress by aiding the production of neurotransmitters like dopamine and norepinephrine. Great for high-pressure training, competition days, or long workouts. PMID: 26424423
Best for: Focus, mood, and performance under stress.
Training hard is only part of the equation. Recovery and supplementing smartly - with the right ingredients, at the right time, for the right goals - can truly take your performance to the next level.
I've seen firsthand how a targeted supplement strategy can amplify training outcomes, accelerate recovery, and elevate long-term results.
Every product in the Musashi range is backed by science and trusted by athletes who demand the best.
When you align your supplements with your goals, you give yourself the tools not just to train harder - but to adapt, improve, and perform at your best.
