Levels chart
Normal blood sugar range: a levels chart for fasting and A1C
The normal blood sugar range for adults who are not pregnant is a fasting plasma glucose of 99 mg/dL or below and an A1C below 5.7%, per NIDDK. Prediabetes is 100 to 125 mg/dL or 5.7% to 6.4%. Diabetes is 126 mg/dL or above, or 6.5% or above. One reading is not a diagnosis.

The chart
What is the normal blood sugar range?
The normal blood sugar range, for adults who are not pregnant, is a fasting plasma glucose of 99 mg/dL or below and an A1C below 5.7% (NIDDK, Diabetes tests and diagnosis).
NIDDK builds its chart from American Diabetes Association criteria. Read across a row to see the two tests side by side.
| Result | Fasting plasma glucose | A1C |
|---|---|---|
| Normal | 99 mg/dL or below | Below 5.7% |
| Prediabetes | 100 to 125 mg/dL | 5.7% to 6.4% |
| Diabetes | 126 mg/dL or above | 6.5% or above |
After eating
What is a normal blood sugar after meals?
We found no source in our set that gives a normal range for readings taken after meals, so we do not print one.
NIDDK's table does include a 2-hour glucose tolerance test, but that is a lab test a clinician runs, not a home check after lunch. If you test at home, ask your care team what targets they want for you and when to test.
Try the lookup for a fasting or A1C number. It matches your number to the NIDDK rows only.
Test ranges for adults who are not pregnant (NIDDK, from ADA criteria)
| 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 |
Usually a second test confirms diabetes. Pregnancy uses different cutoffs. These are ranges for tests a clinician orders; a supplement cannot tell you where you are. (NIDDK, Diabetes tests and diagnosis)
Why one number is not enough
Does one high reading mean diabetes?
No. NIDDK says that usually a second test confirms diabetes, so one reading starts a conversation rather than ending it (NIDDK, Diabetes tests and diagnosis).
Low readings have their own rule. For many people with diabetes, below 70 mg/dL is low, and NIDDK says to eat or drink 15 to 20 grams of glucose or carbohydrate and recheck in 15 minutes (NIDDK, Low blood glucose (hypoglycemia)). Your own targets may differ, so ask your team.
Keep taking prescribed medicine exactly as directed. Signs of severe low blood sugar (confusion, fainting, seizure), chest pain or trouble breathing: call 911.

Does Olivaro keep blood sugar in the normal range?
We found no study showing that, and the label does not promise it.
The bottle front prints “Balanced Blood Sugar Advanced Support*”, and the star leads to the FDA statement that the claim has not been evaluated. Olivaro is a liquid dietary supplement with chromium at 0.7 mcg (0.7 / 35 = 2% of the Daily Value) and a 200 mg blend of 22 ingredients with no individual amounts. No trial tested it. Only a clinician's tests show where your numbers sit.

FAQ
Olivaro questions people ask
What is a normal blood sugar level for adults?
For adults who are not pregnant, NIDDK lists a fasting plasma glucose of 99 mg/dL or below and an A1C below 5.7% as normal. Your clinician may set different personal targets if you have diabetes, so ask what applies to you.
Is a fasting reading of 126 mg/dL diabetes?
It falls in the diabetes range, which NIDDK sets at 126 mg/dL or above. Even so, NIDDK says a second test usually confirms the diagnosis. Share the number with your clinician soon and ask what retest or next step they want.
Why does my home meter differ from my lab result?
We found no source in our set that explains meter accuracy. A home meter reading is your own data, taken at your own time and method. Bring the meter to your clinician or pharmacist and ask them to check how it compares.
