Fasting Blood Sugar and A1C: The Numbers to Track
Updated November 5, 2026 · 4 min read
The short answer
Three numbers tell the story: your fasting glucose in the morning, your glucose two hours after a meal and your A1C every three months. Write the first two down before you start Cinna Shield and every week after. Most people can’t feel a 20-point change. They can see it.
The ranges doctors use
| Test | Normal | Prediabetes | Diabetes |
|---|---|---|---|
| Fasting glucose | Under 100 mg/dL | 100 to 125 mg/dL | 126 mg/dL or higher |
| Two hours after a glucose drink (lab test) | Under 140 mg/dL | 140 to 199 mg/dL | 200 mg/dL or higher |
| A1C | Under 5.7% | 5.7% to 6.4% | 6.5% or higher |
These are the American Diabetes Association’s diagnostic ranges. A diagnosis is made by a doctor, usually with a repeat test, not by one reading at home.
If you already have diabetes
The targets many adults are given are an A1C under 7%, 80 to 130 mg/dL before meals and under 180 mg/dL two hours after the start of a meal. Your doctor may set different targets for you. Use yours.
What each number tells you
- Fasting glucose is the morning snapshot. It is the first reading most Cinna Shield customers watch, and the maker says it usually starts to move between weeks two and six.
- After-meal glucose shows the spike. Test before and two hours after the same meal once a week. A smaller gap is the change you are looking for.
- A1C is the three-month average. It moves slowly by design, so one or two months is too early to judge it.
How to keep a log that means something
- Same time, same conditions. Morning, before food or coffee, washed hands.
- Three baseline mornings before the first capsule. Average them. That is your starting line.
- One number per week. Average the seven mornings. Compare weeks, never single days.
- Note what changed. New medication, illness, bad sleep, a holiday. They all move the meter.
- Bring it to your doctor. A page of weekly averages is worth more than any story.
Reading a change
| What you see | What it may mean |
|---|---|
| Weekly average falling 5 to 10 points over a month | A real trend. Keep going and keep logging. |
| Up and down with no direction | Too early, or too many things changing at once. |
| Readings under 70 mg/dL | Low blood sugar. Treat it as you were taught and call your doctor, especially on insulin or a sulfonylurea. |
| Nothing different by day 80 | Use the 90-day guarantee. That is what it is for. |
