Creatine monohydrate is the most researched and proven supplement in the fitness world — and yet it is still surrounded by confusion and myths. If you are new to the gym and wondering whether creatine is worth taking, this guide is for you.
I have been using creatine consistently for years. It is one of the few supplements I would genuinely recommend to anyone who trains seriously. In this guide, I will break down everything you need to know: what it does, how to take it, which brands are worth buying in the UK, and whether the myths you have heard are true.
What Is Creatine Monohydrate?
Creatine is a natural compound found in your muscles. Your body makes some of it on its own, and you also get it from foods like red meat and fish. Creatine monohydrate is simply the supplemental form — the same molecule, just concentrated into a powder.
When you supplement with creatine, you increase your muscles phosphocreatine stores. This gives your muscles more energy during high-intensity exercise like lifting weights or sprinting. The result? You can push out a few more reps, lift slightly heavier, and recover a bit faster between sets.
Over time, those extra reps add up to more muscle growth and better strength gains. It is not a magic pill — you still have to train hard and eat properly — but it gives you a genuine edge.
What Does Creatine Actually Do?
Here is what the research consistently shows creatine can do:
- Increases strength — most studies show a 5-10% improvement in maximal strength
- Builds more muscle — by allowing you to train harder, you stimulate more muscle growth over time
- Improves power output — better performance in explosive movements like sprints and jumps
- Speeds up recovery — helps replenish energy stores between sets and between workouts
- May support brain function — emerging research suggests cognitive benefits too
What creatine does NOT do: it will not make you huge overnight, it will not burn fat directly, and it will not replace hard training.
How to Take Creatine (The Simple Way)
Forget everything you have heard about complicated loading phases and cycling. Here is the simplest, most effective approach:
Daily Dose
Take 3-5g of creatine monohydrate every single day. That is it. No loading phase needed, no cycling on and off. Just 3-5g daily, consistently.
Timing
It genuinely does not matter when you take it. Before training, after training, with breakfast — pick a time that works for you and stick with it. Consistency matters more than timing.
How to Mix It
Creatine monohydrate is unflavoured and mostly tasteless. Mix it into water, your protein shake, juice, or whatever you are drinking. Stir it well — some cheaper brands can be a bit gritty.
Do I Need a Loading Phase?
No. The old-school approach was to take 20g per day for a week to saturate your muscles faster, then drop to 5g daily. This works but it is unnecessary. Taking 3-5g daily will fully saturate your muscles within 3-4 weeks anyway, without the potential bloating and stomach discomfort that loading can cause.
Best Creatine Monohydrate UK: My Recommendations
Creatine is creatine — the ingredient itself is the same across brands. The differences come down to purity, mixability, and price. Here are my top picks available in the UK right now:
1. Optimum Nutrition Micronised Creatine — Best Overall
My Experience: This is the one I keep coming back to. I have bought it twice now and it is consistently good. The micronised powder mixes much better than cheaper options — no gritty residue at the bottom of your shaker. It is unflavoured so you can throw it in anything without changing the taste.
Key Details:
- Size: 634g (186 servings at 3.4g per scoop)
- Price: Around £28 for 634g (often on sale)
- Type: 100% pure creatine monohydrate, micronised
- Rating: 4.6 stars from 32,000+ reviews on Amazon
- Amazon Choice product
Why I recommend it: Trusted brand, excellent mixability, great value for the 634g tub. If you want to buy once and not think about it for months, this is the one.
2. Nutrition Geeks Pure Creatine — Best Budget Pick
Overview: This is the current Amazon Best Seller in creatine and for good reason — 90 servings for under £10 is incredible value. It dissolves easily, which is unusual for budget brands. A great choice if you want proven creatine without spending much.
Key Details:
- Size: 315g (90 servings)
- Price: Around £9.49
- Type: Micronised creatine monohydrate, vegan
- Rating: 4.5 stars from 3,700+ reviews
- 40K+ bought in past month
Why consider it: If budget is your priority, this is the best value creatine on Amazon UK right now. The reviews are solid and it is a UK brand.
3. Warrior Creatine Monohydrate — Good All-Rounder
My Experience: I have tried this one and it does the job. Nothing fancy, just solid creatine at a fair price. Warrior is a well-known UK brand in the supplement space. The 300g tub lasts about 2 months at 5g per day. Mixes reasonably well — not quite as smooth as ON but no major complaints.
Key Details:
- Size: 300g (100 servings at 3g per scoop)
- Price: Around £8.32
- Type: Pure micronised creatine monohydrate
- Rating: 4.4 stars from 3,900+ reviews
- Available in 7 flavours (including unflavoured)
Why consider it: Affordable, available in flavoured options if you hate plain powder, and from a trusted UK brand. Good entry-level choice.
4. Applied Nutrition Creatine Monohydrate
Overview: Applied Nutrition is a brand I trust — their whey protein is one of my favourites. Their creatine is solid too. Slightly pricier than budget options but you are paying for a reputable brand with good quality control.
Key Details:
- Size: 250g
- Price: Around £14.99
- Type: 100% micronised creatine monohydrate
- Rating: 4.7 stars from 250+ reviews
- Available in multiple sizes and flavours
5. MyProtein Impact Creatine — Best for Bulk Buying
Overview: MyProtein offers creatine in sizes up to 1kg, which makes it the cheapest per serving when bought in bulk during sales. Like their whey, the key is to wait for a sale — never pay full price.
Key Details:
- Size: 500g (147 servings)
- Price: Around £10 (often cheaper during sales)
- Type: Creatine monohydrate
- Rating: 4.6 stars from 3,100+ reviews

Creatine Myths Debunked
Myth: Creatine is a steroid
False. Creatine is a natural compound found in meat and fish. It has nothing to do with anabolic steroids. It is one of the most studied supplements in history and is completely legal and safe.
Myth: Creatine damages your kidneys
False for healthy people. Dozens of studies have shown creatine is safe for people with healthy kidneys, even with long-term use. If you have pre-existing kidney issues, consult your doctor first — but for the average gym-goer, this is not a concern.
Myth: Creatine makes you bloated and puffy
Partially true, but misleading. Creatine does cause your muscles to hold a bit more water. This is actually a good thing — it is intramuscular water, not the puffy water retention people think of. You might gain 1-2kg in the first couple of weeks, but it is water inside your muscles, making them look fuller — not fat.
Myth: You need to cycle creatine
False. There is no benefit to cycling on and off. Take it every day, year-round. Your body does not build up a tolerance to it.
Myth: Creatine causes hair loss
Unproven. This comes from a single study in 2009 that showed increased DHT levels. No study since has replicated this finding. The evidence is extremely weak and most researchers consider this myth debunked.
Frequently Asked Questions
Is creatine safe for teenagers?
Creatine is generally considered safe for people over 18. For teenagers, the research is limited. If you are under 18, focus on training and nutrition first — you do not need supplements at that stage.
Can women take creatine?
Absolutely. Creatine works the same way regardless of gender. Many women avoid it because of the water retention myth, but the actual effect is minimal and the strength benefits are well worth it.
Do I need creatine if I eat a lot of meat?
You would need to eat roughly 1kg of raw beef daily to get 5g of creatine from food alone. Supplementing is far more practical and cost-effective.
Monohydrate vs HCL vs Ethyl Ester — which is best?
Creatine monohydrate. Every time. It is the most researched, most proven, and cheapest form. Other forms like HCL and ethyl ester have marketing behind them but no evidence they work better. Save your money and stick with monohydrate.
Should I take creatine on rest days?
Yes. Creatine works by keeping your muscles saturated over time. You need to take it every day — training days and rest days — to maintain those levels.
How long does it take to see results?
You will likely notice increased strength within 2-4 weeks of consistent use. Visual changes (fuller muscles) can appear within the first week or two due to increased water retention in the muscles.
My Final Take
Creatine monohydrate is one of the very few supplements that genuinely works. It is cheap, safe, well-researched, and effective. If you are training seriously and not taking creatine, you are leaving gains on the table.
My personal recommendation: grab a tub of Optimum Nutrition Micronised Creatine if you want the best quality, or Nutrition Geeks if you want the best value. Take 5g every day, train hard, and let the results speak for themselves.
