What is a healthy A1C level by age? A healthy A1C indicates long-term blood sugar control. For adults under sixty, an A1C below five point seven percent is considered normal. For those over sixty, slightly higher levels, up to six percent, may be acceptable due to health factors. Always consult your doctor to set personalized goals based on your health status. Maintaining a balanced diet, exercising, and regular monitoring can help manage your A1C levels effectively.
