Creatine, electrolytes & protein:
your no-nonsense guide to gym supplements
Walk into any gym and you'll see water bottles, shaker cups, and a rainbow of supplement pouches. But with so much noise out there, it can be hard to know what's actually worth your money — and what's just clever marketing. At Stack House Gym in Westcliff-on-Sea and Rayleigh, we're all about cutting through the clutter. Here's our honest, science-backed guide to three gym supplements that can make a genuine difference to your training.
Benefits of creatine for gym training
Creatine is arguably the most well-researched sports supplement in existence. It occurs naturally in your muscles and helps produce ATP — the energy currency your body relies on during short, explosive bursts of effort like lifting, sprinting, or a tough functional fitness circuit.
Supplementing with creatine tops up your muscle creatine stores beyond what diet alone can achieve. The result? You can push harder, lift heavier, and squeeze out those extra reps that make the real difference over time.
How much creatine should I take?
Creatine monohydrate is the gold standard form — affordable, effective, and extensively studied. A daily dose of 3–5g is all you need. There's no need to “load” or cycle it; consistency is what matters. Take it at the same time each day, with or without food.
Benefits of electrolytes for exercise and hydration
You already know that staying hydrated matters — but plain water doesn't always cut it, especially during intense or prolonged training. When you sweat, you lose more than just water. You lose key minerals — sodium, potassium, magnesium, and calcium — that are essential for muscle function, nerve signalling, and sustained energy levels.
Electrolyte supplements replenish these minerals, helping you maintain performance from the first rep to the last. They can also reduce the cramping, fatigue, and brain fog that come with dehydration — all things that quietly sabotage a good training session.
When should I take electrolytes?
Electrolytes are beneficial before, during, or after exercise — particularly for sessions lasting over 45 minutes, or any class where you're working up a significant sweat. Look for products that are low in added sugar. Even lower-intensity sessions like Yoga or Pilates can benefit from electrolyte replenishment, especially in warmer months.
Benefits of protein supplements for muscle recovery
Protein is the building block of muscle. Every time you train, you create tiny tears in your muscle fibres — and it's protein that repairs and rebuilds them, making them stronger in the process. The challenge for many people is simply getting enough protein from food alone, particularly with a busy lifestyle.
Protein supplements — whey, casein, or plant-based options like pea or rice protein — offer a convenient, easily digestible way to hit your daily protein targets. Whey protein in particular is fast-absorbing, making it ideal post-workout when your muscles are most primed to use it.
How much protein do I need after a workout?
Aim for a protein supplement with at least 20–25g of protein per serving and minimal fillers or artificial additives. You don't need to consume it immediately post-workout — total daily protein intake matters far more than exact timing. Find what fits your routine and stick to it.
Are supplements safe to take every day?
Creatine monohydrate, electrolytes, and protein supplements are all safe for daily use for healthy adults. As with any supplement, we'd always recommend checking with a healthcare professional first — especially if you have any existing health conditions or are taking medication.
Do I need supplements to see results at the gym?
No — supplements support your training, they don't replace good habits. A balanced diet, consistent training, and quality sleep are the foundation. Supplements like creatine and protein can meaningfully accelerate your progress when those foundations are in place.
Can women take creatine and protein supplements?
Absolutely. Creatine and protein supplements are equally beneficial for women. Creatine will not cause bulking — it supports strength and recovery. Protein helps with lean muscle maintenance and body composition goals, regardless of gender.
