Ambrosia Systems is a health technology company operating at ambrosiasys.com that develops continuous glucose monitoring (CGM) hardware and companion mobile applications. Its product lineup targets both insulin-dependent users requiring clinical-grade monitoring and everyday consumers interested in non-invasive wellness tracking.
The flagship product is the RIZZ, described as the world's first non-invasive CGM ring. In addition to glucose, RIZZ tracks sleep, stress, heart health, activity, blood oxygen levels, and skin temperature — all without finger pricks or adhesive sensors. The company positions RIZZ against competitors such as the Oura Ring, emphasizing its glucose-monitoring capability as a key differentiator.
For insulin-dependent users, Ambrosia offers the Waterproof NightRider BluCon, an electronic device that reads data from compatible Abbott FreeStyle Libre NFC sensors and transmits readings via Bluetooth to a smartphone. The companion LinkBluCon app is available on both Google Play and the Apple App Store, with monthly and annual subscription options. Ambrosia explicitly notes that its apps and devices are not FDA approved and readings should not be used for medical decisions.
