What the AI looks for in Creatine Nutritional Supplements
- Form
- Creatine monohydrate (micronized is fine) HCl, ethyl ester and buffered forms cost more and have not been shown to work better.
- Daily dose
- 3 to 5 g per day; an optional loading phase is about 20 g per day split into doses for 5 to 7 days Saturation, not timing, drives the benefit, so the daily dose is what matters.
- Third-party testing
- NSF Certified for Sport or Informed Sport if you are drug tested These verify both the label claim and the absence of banned substances.
- Format
- Powder or capsules over gummies Independent testing has found many creatine gummies contain far less creatine than labelled.
- Ingredient list
- Creatine as the only ingredient Blends dilute the dose and add cost.
Brands that matter
- Optimum Nutrition: Mainstream, widely available micronized monohydrate.
- Thorne: NSF Certified for Sport creatine.
- Klean Athlete: Sport-certified line aimed at tested athletes.
- Nutricost: Budget single-ingredient monohydrate.
What to avoid
- Creatine gummies
- Premium 'advanced' forms (HCl, ethyl ester, buffered) sold as superior
- Proprietary pre-workout blends used as a creatine source
Questions
Do I need to load creatine?
No. Loading saturates muscles in about a week, while 3 to 5 g daily gets there in about three to four weeks with the same end result.
