Fasting Insulin
Insulin moves sugar from your blood into your cells. When cells stop responding well (insulin resistance), the body makes more insulin to compensate, often years before blood sugar or HbA1c rise.
Your reading
This app uses 2–25 mIU/mL, the typical lab range. Many clinicians consider values in the upper part of that range an early sign of insulin resistance, especially alongside high triglycerides or weight around the waist. Combined with fasting glucose, it gives HOMA-IR.
What may help
- —Regular exercise, particularly strength training, which improves insulin sensitivity
- —Fewer refined carbs and sugary drinks; more fiber and protein
- —Enough sleep: even a few short nights reduce insulin sensitivity
When to talk to a doctor
If fasting insulin is high, or high-normal with rising glucose, HbA1c or triglycerides. Insulin resistance is very reversible when caught early.

What is a normal Fasting Insulin level?
Daygo uses 2–25 mIU/mL as the reference range. This app uses 2–25 mIU/mL, the typical lab range.

How can I improve my Fasting Insulin?
Regular exercise, particularly strength training, which improves insulin sensitivity. Fewer refined carbs and sugary drinks; more fiber and protein. Enough sleep: even a few short nights reduce insulin sensitivity.
When should I see a doctor about Fasting Insulin?
If fasting insulin is high, or high-normal with rising glucose, HbA1c or triglycerides. Insulin resistance is very reversible when caught early.
