For a non-diabetic individual, a normal A1C level is typically below 5.7%. This percentage reflects the average blood sugar levels over the past 2-3 months. Here’s a breakdown of A1C ranges:

A1C Range Interpretation

Below 5.7% Normal
5.7% to 6.4% Prediabetes
6.5% or higher Diabetes

Maintaining an A1C below 5.7% is generally considered healthy and indicates good blood sugar control. If your A1C is in the prediabetes range, lifestyle changes such as diet and exercise can help prevent progression to diabetes.
