There are going to be four random episodes like this between now and the end of May, timed with our 9-year anniversary — each one giving you a chance to enter.
Cutting Through the Noise on Supplements
Today, we’re cutting through the noise on supplements.
The supplement industry is worth over £150 billion globally — and it profits from one thing: your confusion.
So today, I’m going to break down:
- What actually works
- What’s a complete waste of money
- And one thing you should do before buying anything at all
The Reality of Supplement Marketing
A few days ago, I walked into a supplement store.
Every product promised insane results.
What I’ve seen over the years is this:
The problem is, many of these products don’t actually deliver results — they just sell well.
The Three Categories of Supplements
Most supplements fall into three categories:
- Completely useless — no real evidence
- Marginally effective — tiny benefit, not worth the cost
- Evidence-based — proven with consistent results
The reality?
Fix the Basics First
Before even thinking about supplements, you need to fix the basics:
- Nutrition
- Training
- Sleep
- Consistency
If your diet is a mess, no supplement will fix it.
What Actually Works
1️⃣ Protein Powder
Protein powder isn’t essential — but it’s incredibly convenient.
You can get all your protein from whole foods, but when you’re busy, a shake can help you hit your targets more easily.
One scoop gives around 20–30g of protein, it’s quick, portable, and easy to use.
2️⃣ Creatine Monohydrate
Creatine is one of the most researched supplements in history.
It helps your muscles produce energy during high-intensity efforts like lifting weights.
This means:
- More reps
- Slightly heavier lifts
- Better recovery
Over time, that leads to more strength and muscle.
3️⃣ Vitamin D
Most people are deficient in vitamin D — especially if they don’t get enough sunlight.
It supports:
- Immune function
- Bone health
- Mood
- Recovery
4️⃣ Magnesium
Magnesium can help with sleep, recovery, and muscle relaxation — particularly if you’re deficient.
If you struggle with sleep or train hard, it may be worth considering.
5️⃣ Omega-3 (Fish Oil)
Omega-3s can support:
- Heart health
- Recovery
- Inflammation
If you’re not eating fatty fish regularly, supplementation can act as an “insurance policy.”
What You Don’t Need
Here’s what you can confidently skip:
- BCAAs (if you hit protein targets)
- Fat burners
- Testosterone boosters
- Detox products
- Greens powders
You’re better off eating real food and focusing on the basics.
The Most Important Step
Before buying any supplement, get a blood test.
This shows what you’re actually deficient in — instead of guessing or relying on marketing.
Then follow professional advice and supplement only what’s needed.
Final Message
People who get results don’t rely on stacks of supplements.
- Eating enough protein
- Training consistently
- Sleeping well
- Moving daily
Supplements are just that — supplements.
Competition
Now for today’s competition — two truths and one lie:
- Creatine is the most researched supplement and improves strength, muscle mass, and recovery
- BCAAs are worth taking even if you hit your protein target
- Getting a blood test is more useful than relying on supplement recommendations
