what is the optimal blood glucose level for most adults

The optimal blood glucose levels for most adults are as follows:

• Fasting Blood Glucose (before meals): 70–99 mg/dL (3.9–5.5 mmol/L)
• Postprandial Blood Glucose (1-2 hours after meals): Less than 140 mg/dL (7.8 mmol/L)
• Hemoglobin A1C (average over 2-3 months): Less than 5.7%

These ranges may vary slightly depending on individual health conditions, age, and other factors. Always consult with a healthcare provider for personalized targets.
