Jewel Windler 24 May 2025

Are you truly in the dark about what your A1C number signifies? Knowing your A1C is not just a number; it's a crucial insight into your metabolic health and long-term well-being, and understanding it could be the key to preventing life-altering complications.

The normal A1C number is a vital metric, representing your average blood sugar level over the preceding 2 to 3 months. This isn't some abstract concept; it's a direct reflection of how well your body is managing glucose, and its measured via a simple blood test routinely used to diagnose and manage diabetes.

Specifically, for adults without diabetes, the normal A1C number typically falls between 4% and 5.6%. However, the target shifts for individuals diagnosed with diabetes, where the aim is generally to keep the A1C number below 7%. These targets aren't arbitrary; they're based on extensive research linking A1C levels to the risk of diabetes-related complications.
