Best Creatine Supplements, Scored on a Public Rubric
Creatine monohydrate is one of the most-researched sports supplements on the shelf — the International Society of Sports Nutrition's 2017 position stand calls it "the most effective ergogenic nutritional supplement currently available" for high-intensity exercise. Form matters less than most brands would have you believe: monohydrate is the gold standard; "advanced" forms like HCl and buffered creatine have not demonstrated superior outcomes in head-to-head trials. We scored five widely-available options, weighted toward third-party testing and price per effective gram.
Top pick
Optimum Nutrition — Creatine Monohydrate Powder (Micronized)
5g creatine monohydrate per serving, 600g tub, Creapure-grade micronized
Thorne — Creatine Monohydrate

How we scored
Every product below is scored on six metrics, 0-10 each, with the weighting described on how we review. The criteria specific to this category:
- Creatine monohydrate (the form with the deepest research base).
- Micronized for easier mixing (no loss of efficacy compared to non-micronized).
- Creapure® certification (German-sourced, tested for contaminants and dicyandiamide content) where available.
- Third-party testing — Informed Sport or NSF for competitive athletes.
- Price per 5g effective serving.
- Clean labels — single ingredient, no proprietary 'creatine matrix' blends.
What to know before buying
- Standard dosing: 5g per day, every day. No need to 'cycle'. No benefit to mega-loading beyond the initial 5-7 day saturation phase.
- Take with or without food — research shows timing has minimal effect on saturation after 3-4 weeks of daily use.
- Water retention is normal and temporary in the first weeks; it reflects intracellular hydration, not bloating.
- HCl, malate, and buffered forms cost more and lack equivalent clinical evidence. Monohydrate is the right default.

Frequently asked questions
The hair-loss claim traces to a single 2009 study in rugby players that observed elevated DHT (a hair-loss-associated hormone) after creatine loading. That study has not been replicated in any of the dozens of subsequent creatine trials. Current evidence does not support a meaningful creatine-to-hair-loss link in the general population, but the question remains open.
