Myprotein Creatine vs Optimum Nutrition Creatine: Which to Buy?
Quick Verdict
Both products contain creatine monohydrate — the same proven ingredient. Optimum Nutrition uses Creapure-certified creatine with guaranteed purity. Myprotein costs significantly less. For most people, the cheaper option is the smarter buy.
Product Comparison
| Factor | Myprotein Creatine Mono | ON Micronised Creatine |
|---|---|---|
| Type | Creatine monohydrate | Creatine monohydrate |
| Creapure certified | No | Yes |
| Serving size | 5g (1 scoop) | 3.4g (1 scoop) |
| Protein | 0g | 0g |
| Other ingredients | None | None |
| Micronised | No | Yes |
| Flavoured options | Unflavoured only | Unflavoured only |
Both are unflavoured, pure creatine monohydrate with no fillers, sugars, or additives. The active ingredient is identical.
Price Comparison
| Size | Myprotein | Optimum Nutrition |
|---|---|---|
| ~500g | ~£17 | ~£20 (317g) |
| Cost per 5g serving | ~£0.17 | ~£0.32 |
| Monthly cost (5g/day) | ~£5.10 | ~£9.60 |
| Annual cost | ~£62 | ~£115 |
Myprotein is roughly half the price per serving. Over a year, that’s a saving of about £53 — enough to buy several months of extra supply.
What Is Creapure?
Creapure is a brand of creatine monohydrate manufactured by AlzChem in Germany. It’s produced using a patented process and tested for impurities like dicyandiamide (DCD) and dihydrotriazine (DHT). Creapure certification means:
- Manufactured in a dedicated facility in Germany
- Batch-tested for contaminants
- Guaranteed 99.99% pure creatine monohydrate
This doesn’t mean non-Creapure creatine is impure — it just hasn’t been through the same testing process.
Does Micronised Matter?
ON’s creatine is micronised, meaning the particles are ground finer. This improves mixability — it dissolves more quickly and leaves less grit at the bottom of your glass. Myprotein’s non-micronised powder is slightly grittier but still mixes adequately with a good stir or shake.
If you’re mixing creatine into a protein shake or smoothie, you won’t notice the difference. If you’re stirring it into water alone, micronised is noticeably smoother.
Packaging
Myprotein uses resealable foil pouches (250g, 500g, 1kg). ON uses plastic tubs (144g, 317g, 634g). Both seal well. ON’s tub is more convenient for daily scooping; Myprotein’s pouch takes up less shelf space.
Note that ON’s scoop delivers 3.4g, not the recommended 5g. You’ll need a heaped scoop or a scoop-and-a-half to hit the optimal daily dose.
Quality and Testing
Myprotein products are manufactured in the UK and many carry Informed Sport certification (third-party tested for banned substances). ON is manufactured across multiple global facilities with its own quality assurance programme. Both brands are reputable with long track records.
Who Each Product Suits
Choose Myprotein if you:
- Want the lowest cost per serving
- Are happy with standard (non-micronised) powder
- Already order from Myprotein regularly
- View creatine as a commodity ingredient (which it essentially is)
Myprotein Creatine Monohydrate
Choose Optimum Nutrition if you:
- Want Creapure-certified purity
- Prefer micronised powder for better mixing
- Value the reassurance of third-party purity testing
- Don’t mind paying a premium for peace of mind
Optimum Nutrition Micronised Creatine
Final Recommendation
Creatine is creatine. Both products contain the same molecule and will produce the same results. Myprotein is the rational choice for most people — save your money and spend it on food instead. If purity certification genuinely matters to you (competitive athletes subject to testing, for example), ON’s Creapure certification is worth the premium.
