Who should buy which

Pick the Ambrosia Systems RIZZ if

Buyers who completed a CGM program (Levels, Veri, Nutrisense) and want continuous glucose-trend data without re-applying a real CGM every 14 days.

Skip if

You are newly curious about glucose - start with a real CGM (Levels or pharmacy Libre) for the first 30-60 days. RIZZ is for the after-program use case.

Pick the Levels Levels Membership if

Anyone wanting to understand their personal food/exercise/sleep response to glucose, or working on insulin sensitivity.

Skip if

You're prone to obsessing over normal variation, or you already have well-managed metabolic health and don't need data.
