Most people think a serious supplement stack costs £100+ per month. It does not. I take seven evidence-based supplements every single day and my total monthly cost is under £40. Here is exactly how I do it, with every product, price, and money-saving trick I use.
No sponsored products. No exaggeration. Just my actual purchases broken down to the penny.
My Complete Stack: The Numbers
| Supplement | Product | Tub Price | Lasts | Monthly Cost |
|---|---|---|---|---|
| Whey Protein | Applied Nutrition Critical Whey 2.27kg | £38 | ~2.5 months | £15.20 |
| Creatine | ON Micronised Creatine 634g | £28 | ~6 months | £4.67 |
| Magnesium | Nutrition Geeks 3-in-1 (90 caps) | £7.64 | ~3 months | £2.55 |
| Vitamin D3+K2 | Nutrition Geeks D3+K2 (365 tabs) | £8.49 | ~12 months | £0.71 |
| B-Complex | Igennus Super B-Complex (60 tabs) | £8.49 | ~2 months | £4.25 |
| Krill Oil | WeightWorld Krill Oil (180 caps) | £22.49 | ~3 months | £7.50 |
| Collagen | Revive Naturals Multi Collagen 400g | £14.99 | ~3 months | £5.00 |
| TOTAL MONTHLY COST | £39.88 | |||
Under £40 per month for a comprehensive, evidence-based stack. That is less than what most people spend on their Netflix, Spotify, and takeaway coffee combined.
The Yearly Perspective
| What | Yearly Cost |
|---|---|
| My entire supplement stack | £478 |
| One coffee per day from Costa | £1,095 |
| Average UK gym membership | £360 |
| Average UK Netflix + Spotify | £288 |
| One takeaway per week | £1,040 |
When you put it in perspective, £478 per year for supplements that genuinely improve your health, performance, and recovery is outstanding value. Most people waste more than that on things that add nothing to their life.
How I Keep Costs Down (7 Money-Saving Tricks)
1. Buy Bigger Tubs
The price per serving always drops when you buy larger sizes. My Applied Nutrition protein costs £38 for 2.27kg versus £22 for 900g. The bigger tub saves roughly 30% per serving. Yes, the upfront cost is higher, but you save significantly over time.
2. Amazon Subscribe & Save
Amazon offers an extra 5-15% discount when you set up Subscribe and Save on supplements you buy regularly. I have my protein and creatine on auto-delivery every 2-3 months. It saves me about £3-5 per order and I never run out.
3. Choose Value Brands for Vitamins
For vitamins and minerals, the molecule is the same regardless of brand. Nutrition Geeks Vitamin D costs £8.49 for a full year. A premium brand charges £15+ for 3 months of the same thing. The Vitamin D molecule does not care about the label.
4. Skip the Useless Stuff
The biggest savings come from NOT buying things. I used to spend £30/month on BCAAs, £25 on fat burners, and £20 on testosterone boosters. Cutting these useless supplements saved me over £75/month instantly. That alone freed up budget for supplements that actually work.
5. Buy Protein on Value, Not Brand
I switched from ON Gold Standard (£30/kg) to Applied Nutrition (£17-20/kg) for my daily protein and honestly cannot tell the difference in results. I still use ON Gold Standard occasionally because I love the taste, but Applied Nutrition is my cost-effective daily driver.
6. Stock Up During Sales
Amazon Prime Day, Black Friday, and brand-specific sales can save you 30-50% on supplements. I typically buy 3-6 months worth of protein and creatine during these events. The savings compound massively over a year.
7. Use Coffee Instead of Pre-Workout
A cup of coffee costs 10p. A serving of pre-workout costs 75p-£1.00. Over a year of 5 sessions per week, that is a difference of roughly £170-230. Coffee gives you caffeine — the main active ingredient anyway. I save pre-workout for occasional heavy sessions only.
What If I Only Had £20/Month?
If I had to cut my stack to £20/month, here is exactly what I would keep:
| Supplement | Why It Stays | Monthly Cost |
|---|---|---|
| Cheap Whey Protein | Cannot hit protein targets without it | £15 |
| Creatine | Most proven supplement, incredibly cheap | £3 |
| Vitamin D | NHS recommended, costs almost nothing | £0.70 |
| Total | £18.70 |
These three cover the absolute essentials. You can build an impressive physique on just these and a solid diet. Everything else in my full stack is optimisation, not necessity. Read my full supplement stack guide for the tiered approach.
What If I Had £100/Month?
If money was not a concern, I would upgrade a few things but NOT add unnecessary products:
| Change | From | To | Extra Cost |
|---|---|---|---|
| Protein upgrade | Applied Nutrition | ON Gold Standard 2.27kg | +£8/month |
| Add Taurine | Nothing | NOW Foods Taurine | +£4/month |
| Premium Krill Oil | WeightWorld | Aker Superba | +£10/month |
| New total | ~£62/month |
Even with a £100 budget, I would only spend £62. The remaining £38 would go towards better food — which will always have more impact than any supplement. I would NOT add BCAAs, testosterone boosters, fat burners, or any other waste of money products.

Frequently Asked Questions
Is this stack enough for serious muscle building?
Yes. Combined with proper training (progressive overload on compound lifts), adequate protein (2g per kg bodyweight), and good sleep, this stack covers everything an evidence-based approach requires. Read my transformation story to see what this stack helped build.
Could I make it even cheaper?
Yes — the £20/month Essential Stack (protein, creatine, Vitamin D) is the bare minimum and it works. The extra £20 for the full stack is optimisation that I believe is worth it, but it is not strictly necessary for building muscle.
Do I need to take all 7 every single day?
Protein and creatine daily is important. The vitamins and minerals can be missed occasionally without issue — what matters is long-term consistency. If you forget a day, do not stress. Just take your normal dose the next day.
Why Applied Nutrition over ON Gold Standard as daily protein?
Pure value. Applied Nutrition is roughly 30-40% cheaper per serving and the muscle-building results are identical. I use ON Gold Standard when I want the premium taste experience, but for daily cost-effective protein, Applied Nutrition wins.
The Bottom Line
A comprehensive, effective supplement stack does not need to cost a fortune. Under £40 per month covers everything — protein for muscle, creatine for strength, vitamins for health, omega-3 for joints, and collagen for recovery.
The real secret to saving money on supplements is knowing what actually works and ignoring everything else. Five to seven proven supplements will always outperform twenty hyped-up products, both in results and in cost.
Spend smart. Train hard. Be consistent. The results will follow.
