Creatine is one of the most studied supplements for training, and most experts point to the same plain form: creatine monohydrate. That leaves a few things to compare when you shop for men: a 5-gram dose per serving, third-party testing for banned substances, how easily the powder mixes, and what each serving costs. Here is what's available right now.
Our top pick is the 90-serving Thorne creatine. It is NSF Certified for Sport, has a single ingredient, and appears in more expert reviews than any other tub here. The other picks cover a pharmacist-ranked tub, a clean-label option, a non-GMO choice, a budget tub and a value pick.

Why it wins
- NSF Certified for Sport, which checks for nearly 300 banned substances
- One ingredient: 5 g creatine monohydrate per serving
- Mixes easily and tastes of nothing, per one expert review
- Named in three of five expert reviews
One catchThe 90-serving tub is a bigger up-front spend than most picks here, though it lasts longer.
Why it's our top pick
Thorne's 90-serving tub gives you 5 grams of creatine monohydrate per scoop and nothing else, which is the form the expert reviews point to. It carries NSF Certified for Sport, a third-party program that checks for banned substances, so you don't have to take the label's word on what's inside.
It is the pick that appears most often across the reviews we read, and one of them says it mixes easily and tastes of nothing. The larger size means fewer reorders, which matters if you take creatine every day.

Why we like it
This is the Optimum Nutrition unflavored creatine in the 120-serving tub. It gives 5 grams of micronized creatine monohydrate per scoop and is the top-ranked product in one expert review, a pharmacist survey that gave the brand's powder the highest score.

- One of the largest tubs here at about 100 servings
- Named the cheapest creatine that met one review's testing criteria
- Dissolves in water with a shaker bottle
Cons
- Not micronized, so it may clump more than micronized powders
- Heat can damage the product, so store it in a cool place
Read our full take
Why we like it
This is a budget-focused pick. The tub holds about 100 servings of unflavored creatine monohydrate at 5 grams per serving, and it is NSF Certified for Sport. One expert review named it the cheapest creatine that met its testing criteria over the years.
The trade-off is texture. The same review noted it is not micronized and may clump more than micronized powders. Shake it in a sealed bottle, and keep it out of heat, which the listing warns can damage it.

Why we like it
Momentous's 90-serving unflavored creatine gives 5 grams of creatine monohydrate per serving and is NSF Certified for Sport, with Non-GMO and gluten-free labeling. The brand says it is trusted by pro and collegiate teams, which is a brand claim rather than an independent test.

FAQ
Who it's for?
Creatine monohydrate suits men who lift, sprint or do other hard training and want a plain, well-studied supplement. One expert review recommends 3 to 5 grams daily, taken consistently, and says most men can skip a loading phase.
It is not a muscle builder on its own. Expert reviews say creatine works alongside resistance training, not in place of it.
What to look for on the label?
- Creatine monohydrate with 5 grams per serving and no fillers
- Third-party certification such as NSF Certified for Sport or Informed Sport
- Micronized powder, which generally mixes more easily
- Price per serving, not price per tub
What to skip, and who should ask a doctor?
Skip blends that promise to boost testosterone, mega-dose formulas, and products with ingredient lists you can't read. One expert review notes that creatine monohydrate does not raise testosterone.
Speak to a doctor before starting if you have kidney disease, liver disease, diabetes or high blood pressure.
What brand of creatine is the most effective?
None of the sources ranks creatine brands by how well they work in the body. The reviews agree the form matters more than the brand, and plain creatine monohydrate is the most studied option. Choose based on third-party testing, the dose per serving and the price per serving.
What is the best creatine for men over 50?
The sources don't set a different product or dose for men over 50. One expert review recommends 3 to 5 grams daily, taken consistently, with no loading phase needed for most men. Anyone with kidney disease, liver disease, diabetes or high blood pressure should speak to a doctor before starting.
What's the best creatine for men and women?
Plain creatine monohydrate is the form the reviews recommend, and the sources don't set separate doses by sex. Momentous is marketed for both men and women, and it is one of our picks. Any of our picks with 5 grams of monohydrate per serving suits either.
What is the best creatine for men muscle growth?
Creatine helps the body produce energy during short, hard efforts, which can support training. One expert review says creatine monohydrate increases muscle mass, strength and recovery, and says it is safe at recommended doses. Expert reviews also say it won't build muscle on its own, so pair it with resistance training.
