Prediabetes
Prediabetes ranges, symptoms and the test: what to ask a clinician
Prediabetes ranges, per NIDDK, are an A1C of 5.7% to 6.4% or a fasting plasma glucose of 100 to 125 mg/dL, for adults who are not pregnant. A blood test finds it, and a clinician decides what comes next. We found no source in our set on symptoms, and no supplement replaces the test.

The numbers
What are the prediabetes ranges?
Prediabetes ranges sit between normal and diabetes: an A1C of 5.7% to 6.4%, or a fasting plasma glucose of 100 to 125 mg/dL (NIDDK, Diabetes tests and diagnosis).
The cutoffs are for adults who are not pregnant. NIDDK takes them from American Diabetes Association criteria, and says a second test is usually used to confirm diabetes.
| Result | A1C | Fasting plasma glucose |
|---|---|---|
| Normal | Below 5.7% | 99 mg/dL or below |
| Prediabetes | 5.7% to 6.4% | 100 to 125 mg/dL |
| Diabetes | 6.5% or above | 126 mg/dL or above |
What you notice
What are the symptoms of prediabetes?
We found no source in our set that lists prediabetes symptoms, so we will not guess; a blood test is how it is found.
That matters because a normal day tells you little. Many conditions give no clear signs at first. High blood pressure, for example, usually has none (CDC, High blood pressure). If you are worried, ask a clinician rather than waiting for a feeling.
Very high or very low blood sugar is different: confusion, fainting or a seizure needs care right away.
Keep taking prescribed medicine. Signs of severe low blood sugar (confusion, fainting, seizure), chest pain or trouble breathing: call 911.
Getting tested
Who should get a prediabetes test, and what happens next?
A clinician decides who should be tested; we found no source in our set that lists risk factors or screening ages, so ask yours.
A prediabetes test is an A1C, a fasting plasma glucose test, or both. Ask when to repeat it. Between visits, the steps below are general health habits from our sources and a clinician's plan, not a treatment for prediabetes. See when to see a clinician.
- A test, not a guessFasting glucose and A1C tests, ordered by a clinician, show where you are: normal A1C is below 5.7% and diabetes starts at 6.5% (NIDDK). (NIDDK, Diabetes tests and diagnosis)
- Moving most daysThe HHS guidelines say 150 to 300 minutes of moderate activity a week plus muscle strengthening on 2 or more days; walking counts. (CDC, Adult activity)
- SleepAdults need 7 or more hours a night; short sleep is part of the picture in the health-agency pages we read. (CDC, Sleep)
- Know your blood pressureHigh blood pressure usually has no symptoms and often travels with high blood sugar; normal is under 120/80. (AHA, BP readings) (CDC, High blood pressure)
- A clinician's planThe ADA's Standards of Care say herbs and micronutrients are not recommended for glycemic benefit; treatment decisions belong with your health care team. (ADA 2026, Standards of Care, supplements) (NCCIH, Diabetes and dietary supplements)
- Tell your team what you takeNCCIH advises telling your providers about any herbal supplement you use, because supplements can interact with diabetes medicines. (NCCIH, Diabetes and dietary supplements)

Can Olivaro or another supplement replace a prediabetes test?
No. The American Diabetes Association's 2026 Standards of Care say herbs and micronutrients are not recommended for glycemic benefit (ADA 2026, Standards of Care, supplements).
NCCIH adds that it has no reliable evidence any herbal supplement controls diabetes, and warns against replacing medical care with an unproven product (NCCIH, Diabetes and dietary supplements). Olivaro is a liquid dietary supplement whose label makes no claim to treat or prevent prediabetes. The front reads “Balanced Blood Sugar Advanced Support*”, and no trial tested it.

FAQ
Olivaro questions people ask
Does prediabetes always turn into diabetes?
We found no source in our set that gives the odds. NIDDK describes prediabetes as the range between normal and diabetes. Ask your clinician what your results mean, how often to retest and which steps they recommend for you.
Is an A1C of 6.4% prediabetes?
Yes, in the NIDDK table, it is the top of the range. An A1C of 5.7% to 6.4% is the prediabetes range for adults who are not pregnant. One result is a starting point, so ask your clinician whether to repeat it or add a fasting test.
Can I take Olivaro if I have prediabetes?
Ask a clinician or pharmacist first, as the label advises for anyone with a known medical condition. Olivaro makes no claim to treat prediabetes, and no trial tested it. Never stop or change a prescribed medicine because of a supplement.
