Doses are declared per serving in mg. “By weight” is the share of the ingredient that is the nutrient itself (e.g. elemental magnesium in a magnesium salt).

Why Creatine Nitrate is tier 2

A dose-ranging safety/efficacy trial found comparable safety markers and performance outcomes to monohydrate, but the evidence base is much smaller and mostly industry-affiliated.

Why Creatine HCl (Hydrochloride) is tier 2

Marketed on higher-solubility claims; head-to-head RCTs are few and small: two (Londono-Velasquez 2025, n=31, 5 g/day x8 wk; Eghbali 2024) found no advantage over monohydrate, while one small 4-week trial in soccer players (Duan 2026, n=10/group) reported greater short-term performance gains with HCl. No consistent superiority has been shown.

Tiers summarize published comparative bioavailability or outcome evidence for each form (see methodology). This page describes the market; it is not a recommendation to take either form. Talk to a clinician about what's right for you.
