We have not tested products ourselves. How we research
Without a prescription you have two direct options, Dexcom Stelo ($89 a month listed, 15-day sensors) and Abbott Lingo ($54 for a two-week plan), plus coaching services such as Nutrisense and Levels. Prescription sensors like Libre 3 and Dexcom G7 are for people with diabetes. No trial shows a CGM improves health outcomes in healthy people.

The short answer: If you do not have diabetes and want to try a continuous glucose monitor (CGM), you have two direct options in the US: Dexcom’s Stelo, listed at $89 a month with 15-day sensors, and Abbott’s Lingo, listed at $54 for a two-week plan that does not auto-renew (both checked 29 Sept 2026). Services such as Nutrisense and Levels sell coaching on top. Prescription models like Libre 3 and Dexcom G7 are made for people with diabetes. Treat the readings as patterns: an independent study of over-the-counter CGMs found 12.9% average error, and no trial shows a CGM improves health in healthy people.

Neither Nutrisense nor Levels names the sensor brand on the pages we read. Compare the two direct options in detail in Stelo vs Lingo.
Reasonable to try for a fortnight: adults without diabetes who are curious how meals and sleep move their glucose and will change a habit if the graph surprises them. Start with the cheapest way in.
Skip it, or ask a doctor first: anyone with a history of disordered eating (Lingo itself advises consulting a professional), people on glucose-lowering medicines, and anyone who wants a diagnosis. A CGM does not diagnose diabetes. If you are worried, ask for a laboratory test; see best at-home blood tests. To read the graph, use the CGM guide. Details of the Stelo product are in the Dexcom Stelo review.
