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 Magnesium Creatine Chelate is tier 3

A single small (n=35) 2003 RCT showed greater increase in intracellular water vs plain creatine+MgO, but never independently replicated and no trial has shown superior strength/performance outcomes vs monohydrate.

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.
