I run a supplement review website. I earn money when you buy supplements through my links. So you might expect me to tell you that you absolutely need a cupboard full of pills and powders to build muscle or stay healthy.
I am not going to do that. Because the honest truth is: most people waste hundreds of pounds a year on supplements they do not need.
Here is what you actually need, what is optional, and what is a complete waste of money — from someone who has spent years and a lot of his own cash figuring this out.
The Uncomfortable Truth
If your diet is solid, you sleep 7-8 hours, and you train consistently, you can build an impressive physique with zero supplements. Supplements are the last 5-10% — the cherry on top. They are not the cake.
The supplement industry is worth over £140 billion globally. That kind of money creates a lot of marketing pressure to convince you that you need things you do not. Instagram influencers, flashy packaging, and pseudo-scientific claims are designed to separate you from your money.
My job on this site is to cut through that noise and tell you what actually works based on real experience and real science.
The Three Tiers of Supplements
Tier 1: Actually Worth It (Evidence-Based)
These are the supplements with strong scientific evidence behind them and genuine real-world benefits. If you are going to spend money on supplements, start here.
| Supplement | Why It Works | Who Needs It | Monthly Cost |
|---|---|---|---|
| Whey Protein | Convenient way to hit protein targets | Anyone struggling to eat enough protein | £15-25 |
| Creatine Monohydrate | Increases strength, most researched supplement ever | Anyone who trains with weights | £3-5 |
| Vitamin D | NHS recommends for all UK residents | Everyone in the UK, especially winter | £0.70 |
Total cost: roughly £20-30 per month. That is it. These three cover the essentials for 90% of people who train.
Tier 2: Genuinely Useful (Good Evidence)
These have solid evidence and I personally take all of them, but they are not essential. Think of them as upgrades once your basics are covered.
| Supplement | Why It Helps | Who Benefits Most | Monthly Cost |
|---|---|---|---|
| Magnesium | Sleep, recovery, most people are deficient | Hard trainers, poor sleepers | £2-3 |
| Omega-3 (Krill/Fish Oil) | Joints, inflammation, heart health | People who do not eat oily fish regularly | £7-10 |
| Vitamin B Complex | Energy production, nervous system | Hard trainers, vegetarians, stressed individuals | £4-5 |
| Collagen | Joint support, skin, connective tissue | Heavy lifters, people over 30 | £10-15 |
Total cost with Tier 1: roughly £40-60 per month. This is my full daily supplement stack and I genuinely believe every item earns its place.
Tier 3: Waste of Money (Save Your Cash)
These are supplements with weak evidence, overblown marketing, or that are simply unnecessary if you eat a decent diet. I have tried most of these and stopped buying them.
| Supplement | Why It Is a Waste | What to Do Instead |
|---|---|---|
| BCAAs | Redundant if you eat enough protein. Whey already contains all BCAAs | Just drink whey protein |
| Testosterone boosters | None of them work. Zero credible evidence | Sleep more, reduce stress, lift heavy |
| Fat burners | Overpriced caffeine. No supplement burns fat | Calorie deficit + training |
| Mass gainers | Mostly sugar and maltodextrin at a huge markup | Eat more food + whey protein |
| Glutamine | Your body makes enough. Unnecessary for most people | Save your money |
| CLA | Negligible fat loss effects in humans | Calorie deficit |
| Detox supplements | Your liver and kidneys already detox you. Scam category | Drink water, eat vegetables |
| Waxy maize / Dextrose | Just sugar with a fancy name | Eat a banana or rice |
The “Do I Need It?” Decision Framework
Before buying any supplement, ask yourself these three questions:
1. Can I get this from food?
If yes, try that first. Real food is almost always better and cheaper than supplements. Protein from chicken costs less per gram than protein from powder.
2. Is there strong scientific evidence it works?
Not “a study suggests” or “some people believe.” Look for multiple studies, systematic reviews, and meta-analyses. If the only evidence comes from the company selling it, run.
3. Will it make a noticeable difference to my results?
Creatine? Yes — you will measurably lift more weight. BCAAs? No — you will notice zero difference if your protein intake is adequate. Be honest about whether something actually moves the needle.
What I Spend Per Month (Full Transparency)
| Supplement | Product | Monthly Cost |
|---|---|---|
| Whey Protein | ON Gold Standard | ~£20 |
| Creatine | ON Micronised | ~£4 |
| Magnesium | Nutrition Geeks 3-in-1 | ~£2.50 |
| Vitamin D3+K2 | Nutrition Geeks | ~£0.70 |
| B-Complex | Igennus Super B | ~£4.25 |
| Krill Oil | WeightWorld | ~£7.50 |
| Collagen | Revive Naturals | ~£7.50 |
| Total | ~£46.45 |
Under £50 per month for a comprehensive, evidence-based supplement stack. I have cut out everything that did not make a measurable difference. You can see my full breakdown in my supplement stack article.
The Beginner Priority List
If you are just starting out and want to know what to buy first, here is the exact order I would recommend:
Month 1: Whey protein + creatine (£20-25 total). These two give you the biggest bang for your buck.
Month 2: Add Vitamin D + magnesium (£10 total). Cheap health insurance that most UK people need.
Month 3: Add krill oil or fish oil (£7-10). Especially if you do not eat fish regularly.
Month 4+: Consider B-Complex and collagen based on your personal needs.
Never: BCAAs, testosterone boosters, fat burners, mass gainers, or anything that promises miracle results.
Frequently Asked Questions
If supplements are only 5-10%, what is the other 90-95%?
Training consistently (3-5x per week with progressive overload), eating enough protein (check my protein guide), sleeping 7-8 hours, managing stress, and being patient. No supplement compensates for poor training or poor diet.
Why do you sell supplements if most are unnecessary?
Because some genuinely work — and my job is to help you find those and avoid the rest. I would rather you spend £30 on 3 proven supplements than £100 on 10 useless ones. I only recommend products I personally buy with my own money.
My favourite influencer takes 20 different supplements. Should I?
No. Most influencer supplement stacks are sponsored. They take what they are paid to promote, not necessarily what works. Look at what the science says, not what someone on Instagram tells you between sponsored posts.
Are supplements regulated in the UK?
Food supplements in the UK are regulated under the Food Supplements Regulations 2003 and enforced by Trading Standards. However, regulation is not as strict as for medicines. This is why buying from established, reputable brands with third-party testing is important. All the brands I recommend on this site meet proper UK food safety standards.
The Bottom Line
Most supplements are unnecessary. A few are genuinely useful. The trick is knowing the difference.
Focus on training hard, eating enough protein, sleeping well, and being consistent. Then add the proven basics — protein, creatine, Vitamin D — and you are set. Everything else is optional optimisation, not essential.
I would rather you save your money and buy better food than waste it on supplements you do not need. And yes, I know that is an unusual thing to hear from someone who runs a supplement review site. But it is the truth.
