Consider it. Plain creatine at the right dose, with a testing claim nobody can check. 5 g of micronized creatine monohydrate per scoop and no other ingredients on the panel: the same thing as the plain tubs higher on this list, in a package aimed at women.

Why It Scores 8.1 — And The Label Line Behind Each Number
Form purity
25% of scoreMicronized creatine monohydrate, the form behind almost all of the research (Kreider 2017). The panel lists it as the only ingredient. The scoop is printed as 5.15 g against 5 g of creatine, and no other ingredient is named. Not a branded raw material such as Creapure.

Marketing Claims Vs. Reality
Improves strength.
Creatine monohydrate at 3 to 5 g a day with training increases strength; this is the best-supported effect of creatine (Kreider 2017).
Cognitive function.
Some studies find benefits for memory and mental tiredness, more clearly in people who eat little meat or are sleep deprived. The evidence is weaker than for strength.
Third party tested.
The tub says so, but no lab, certificate or seal is named, and we found no listing for this product with NSF.
What Our Test Actually Found
Marketed to women, made like any good creatine
Creatine for women does not need a special formula. Women respond to the same 3 to 5 g a day, and the review by Smith-Ryan 2021 reports that women start with lower creatine stores than men. Bloom puts exactly that in the tub and nothing else.
The testing claim is the weak point
Third party tested on a label means little unless the lab or the certificate is named. Thorne and Sports Research, higher on this list, are listed with NSF; Bloom is not. For most buyers that is a small risk with a single-ingredient powder. For drug-tested athletes it matters.
Water weight is real and temporary
Creatine draws water into muscle, so the scale can move by a kilo or two in the first weeks, mostly when people start with a loading phase (Kreider 2017). It is not fat, and 5 g a day without loading keeps it small.
Full analysis: all pros & cons (7), buy if / skip if
- 5 g of creatine monohydrate per scoop
- No sweeteners, flavors or add-ons on the panel
- Unflavored, mixes into any drink
- $0.50 per serving
- Third-party testing claim names no lab
- Not listed with NSF
- Costs more per gram than the bulk tubs
- You want a plain, unflavored creatine from a brand you already use
- You want 5 g per scoop without sweeteners or add-ons
- You prefer a smaller tub of 40 servings
- You want a certified product: Thorne is on the NSF Certified for Sport list
- You want the lowest price per gram: the bulk tubs cost less
- You expect anything beyond creatine: there is nothing else in it
5 g of micronized creatine monohydrate per scoop and no other ingredients on the panel: the same thing as the plain tubs higher on this list, in a package aimed at women. You pay a little more per gram than for the cheapest tubs, and the third-party testing claim names no lab.
Bloom is sold to women through social media, and creatine sold that way is often a blend with less creatine than it looks. This tub is not. The panel lists one ingredient, creatine monohydrate, 5 g per scoop, and the tub holds 40 servings. That is the dose from the research, at $0.50 a day when we checked. What it does not have is a named testing lab: the tub says third party tested, but neither the label nor the listing names who tested it, and the product is not in NSF's listings.
Good creatine in a women-brand package
If you already like Bloom and want creatine, this is a safe choice: one ingredient, the right dose, a fair price. It ranks below the plain tubs at the top of this list for one reason: they come with a named, checkable test and Bloom does not. Take one scoop a day, every day, with or without training.
If This Doesn’t Fit — Try These
01Sports Research Creapure Creatine
The research dose for women is the same 3 to 5 g a day as for men, and every plain monohydrate here supplies it.
02Thorne Creatine
If you're a drug-tested masters athlete (USATF, Powerlifting America, USAW masters) or you simply want the absolute cleanest tested tub on the market, Thorne is the answer.
08Alani Nu Creatine
Nothing wrong with what is in the tub.
Quick Answers
Is Bloom creatine good for women?
Yes. It is plain creatine monohydrate, 5 g per scoop, which is what the research on women used. Nothing about the formula is specific to women, and it does not need to be.
Does Bloom creatine make you gain weight?
You may gain a little water weight in the first weeks, because creatine draws water into muscle (Kreider 2017). It is not fat.
Is Bloom creatine third-party tested?
The tub says third party tested, but no lab is named and we found no NSF listing. If you need a verified product, Thorne Creatine is NSF Certified for Sport.
How much Bloom creatine should I take?
One scoop, 5 g of creatine, once a day.
