Do You Really Need Supplements?

Walk into any health shop and you’ll see shelves full of powders, pills, and potions promising big results. But do you really need supplements to get fitter, stronger, or healthier?

The truth: no — not if your diet is already balanced. Supplements are exactly that — a way to supplement your nutrition, not replace it.

⚖️ The Pros & Cons of Supplements

Pros:

  • Convenient when whole foods aren’t enough

  • Can help fill gaps in your diet

  • Backed by research in some cases (like creatine and vitamin D)

Cons:

  • They’re not magic — you still need to eat well and train consistently

  • Can be expensive if you’re taking things you don’t really need

  • Not all supplements are created equal (quality matters!)

✅ The Supplements I Recommend

There are just a few that I suggest most people take:

  • Vitamin D3 (4000iu daily): Especially in the UK where we don’t get much sunlight. Supports bones, immunity, and overall wellbeing.

  • Creatine (5–10g daily): One of the most researched supplements in the world. Not only does it help with strength, power, and recovery, but studies also show it can support brain health, memory, and mental performance.

  • Good quality fish oil (if you don’t eat much fish): Supports heart health, reduces inflammation, and can help with joint health and recovery.

  • Good quality Whey protein powder: Not essential, but really useful if you struggle to hit your protein target through food alone. 

Other supplements? They depend on you. If you’re low in something specific (like iron, B12, or magnesium), you’d only know with a blood test — which is also something I recommend people do on an annual basis, especially as you get older.

💡 The Bottom Line

Supplements aren’t magic. They can help — but only when used wisely and alongside a solid diet and training routine but whole foods should always be your priority: lean protein, fruit, veg, carbs, and healthy fats. Think of supplements as a top-up, not the foundation.

At CrossFit Greater Brislington, we help members get the basics right first: training, nutrition, and lifestyle. Once those are in place, supplements can give you an extra edge.

When’s the Best Time to Eat? (How to time meals around training)

Meal timing can make a big difference to your  energy, performance, and recovery  — but it doesn’t have to be complicated. You don’t need to track every bite or plan your day around food. What really matters is  creating simple, consistent habits  that support your training and lifestyle. Here’s how to get it right 👇 🍳 Start Your Day Right Breakfast really does set the tone for your day — especially when it’s  high in protein . A balanced breakfast helps: ✅ Stabilise your energy levels. ✅ Keep you full for longer. ✅ Reduce cravings and snacking later on. Example: Scrambled eggs on wholegrain toast with avocado, or Greek yoghurt with berries and oats. If mornings are hectic, a  protein shake and a banana  are still better than nothing — you’re giving your body fuel to perform. 🏋️‍♂️ Fuel Around Training If you’re training hard (like we do at CrossFit Greater Brislington),  when you eat around your workouts  can make a big difference to how ...

How Often Should You Train?

 This is one of the most common questions we get asked — and honestly, it’s a good one. Some people think they need to train every day to see results. Others worry that if they can only make it two or three times a week, it’s not enough. The truth?  It depends on your goals, your recovery, and your lifestyle. 💪 For General Strength & All-Round Fitness If your goal is to move better, get stronger, and improve your fitness —  training 2–4 times per week  is more than enough when you follow a structured program (like ours). Why? Because progress comes from a balance of  training hard, recovering well, and staying consistent. Even elite athletes build rest days into their week. The magic doesn’t just happen in the gym — it happens when your body adapts between sessions. 🧠 It’s About Quality, Not Quantity Doing 2–4 well-planned, purposeful workouts each week will give you far better results than seven half-hearted sessions with no plan. Each time you train, you...
