Fasting Insulin

Measured in uIU/mL

How hard your pancreas is working to keep glucose normal. Rises years before glucose does — the earliest warning available.

What the numbers mean

These are the ranges BioForge works to. They are not the same as a lab's reference range, which is built from the general population rather than from people who feel well.

Low
<2
Optimal
2–6
High
>8 · >10 = clear insulin · resistance

What moves Fasting Insulin

Driven up by excess body fat (especially abdominal), refined carbohydrates, inactivity, poor sleep and chronic stress. High insulin also crushes SHBG, which distorts your free testosterone reading.
