Top Pick — The Banned-Substance-Tested Default, at 23 Cents a Scoop
From $27.95 (120 servings) · · 4.6/5 stars · 77,710 Amazon ratings
Creatine monohydrate is the most-studied supplement in sports nutrition and also the easiest to overpay for. If you are looking for the best creatine for beginners, the question is not really which formula works — monohydrate is monohydrate — it is which tub you can trust and what it costs per scoop. Optimum Nutrition’s Micronized Creatine answers both: 5g of plain unflavoured monohydrate per serving, Informed Choice banned-substance tested, and 120 servings from about $27.95. That is roughly 23 cents a day.
THE VERDICT
This verdict is built from our analysis of verified Amazon review data, aggregated owner sentiment, and real customer testimonials — not a physical hands-on test by our team. 77,710 ratings at 4.6/5 is one of the largest and most stable review bases in the entire supplement category, and the sentiment is boring in the best possible way: it mixes, it has no taste, it works, people reorder it for years. There is no proprietary blend, no flavour system to dislike, no marketing story to see through — just micronized monohydrate that has been the reference product long enough that most competitors position themselves against it.
The one consistent complaint is texture. Reviewers describe it as grainy and note it does not fully dissolve — it tends to settle at the bottom of a glass of plain water. Owners work around it by mixing into a shake or stirring it into a small amount of liquid first. If you want something that vanishes into cold water, this is not it. If you want the cheapest tested monohydrate per gram, it is.
WHAT WE LIKED
- 5g of pure micronized creatine monohydrate per scoop — the clinically standard dose, no fillers or proprietary blend.
- Informed Choice banned-substance tested, which matters if you compete in any tested sport.
- Roughly $0.23 per serving at the 120-serving size — among the lowest cost-per-gram of any tested creatine.
- Completely unflavoured, so it disappears into a protein shake, coffee or juice without fighting the taste.
- 77,710 ratings at 4.6/5 — an unusually large and consistent evidence base for a supplement.
- Three sizes (60, 120 and 240 servings) so you can trial it cheaply before committing.
WHAT COULD BE BETTER
- It is grainy. Multiple verified buyers report it does not fully dissolve in plain water and settles at the bottom of the glass.
- No scoop-free convenience. Unflavoured powder means you are measuring every day; capsule users will find this a step backwards.
- Price varies by size and seller, and the 60-serving tub is poor value per gram compared with the 120.
- Zero flavour options in the unflavoured line — if you drink it in water and dislike chalky texture, you will want to mix it into something else.
“Been using Optimum Nutrition’s Micronized Creatine Monohydrate for a few months now and it’s honestly one of the best supplement purchases I’ve made.”
“I heard the creatine powder doesn’t taste good, but this one has no taste at all. It doesn’t really dissolve, so I pour a little water onto a scoop of it in a glass.”
OPTIMUM NUTRITION MICRONIZED CREATINE VS. BUCKED UP CREATINE MONOHYDRATE — WHICH SHOULD YOU BUY?
Bucked Up is the other creatine we rate highly, and on paper it is cheaper up front. The real difference is scale of evidence and cost per serving once you account for tub size.

Best Pick — Anyone Who Wants Tested Creatine and No Surprises
If you compete in a tested sport, or you simply want the lowest cost-per-gram from the largest evidence base in the category, Optimum Nutrition is the safer default. Bucked Up is the cheaper entry ticket and rates marginally higher, so it is the better first tub if you just want to try creatine for a month without committing.
