Prediabetes Guide: The Numbers, the Programs and Your Next Steps
Prediabetes means an A1C of 5.7% to 6.4% or a fasting glucose of 100 to 125 mg/dL. About 115.2 million U.S. adults have it. In the Diabetes Prevention Program, a lifestyle program cut the chance of type 2 diabetes by 58%, more than metformin did. No supplement, GlucoZen included, has shown anything close to that.

The basics
What is prediabetes?
Prediabetes means your blood sugar is higher than normal but not high enough to be called diabetes. It is common, it often has no symptoms, and it is a signal worth acting on.
CDC estimates that 115.2 million U.S. adults have prediabetes (CDC, Diabetes statistics). That is a very large group of people, and you may be one of them.
The same CDC report counts 40.1 million people with diabetes in 2023, and 11.0 million of them were undiagnosed (CDC, Diabetes statistics). A routine blood test is often the first clue.
Prediabetes is not a diagnosis of diabetes. It is a range of numbers that shows higher risk, and that risk can be lowered with steps that are well tested.
Know your numbers
What A1C and fasting glucose numbers mean prediabetes?
An A1C of 5.7% to 6.4%, or a fasting glucose of 100 to 125 mg/dL. Type a result to see its range.
| Test | Normal | Prediabetes | Diabetes range |
|---|---|---|---|
| A1C | Under 5.7% | 5.7% to 6.4% | 6.5% or higher |
| Fasting plasma glucose | 99 mg/dL or lower | 100 to 125 mg/dL | 126 mg/dL or higher |
| Confirmation | Not needed | Your clinician may repeat it | Usually confirmed with a second test |
One result is a starting point, not a verdict. A deeper walk through each test is in A1C and fasting glucose numbers explained.
The big trial
What did the Diabetes Prevention Program find?
The Diabetes Prevention Program tested a lifestyle program against metformin and a placebo in people at high risk. Over about 3 years, the lifestyle group lowered their chance of type 2 diabetes by 58%. Metformin lowered it by 31%. In people aged 60 and older, the lifestyle program lowered it by 71% (NIDDK, DPP).
What the goals mean
What do the 7% and 150-minute goals look like day to day?
The trial set two targets: lose about 7% of body weight and get 150 minutes of physical activity a week (NIDDK, DPP). Both are smaller than many people expect.
| Starting weight | 7% goal | Activity split |
|---|---|---|
| 160 lb | About 11 lb | 30 minutes, 5 days a week |
| 200 lb | 14 lb | Three 10-minute walks, 5 days a week |
| 240 lb | About 17 lb | 25 minutes a day, 6 days a week |
Walking counts. So does cycling, dancing or yard work at a brisk pace. Short walks after meals are an easy place to start.
A program near you
What is the CDC National Diabetes Prevention Program?
It is a yearlong lifestyle change program built on the same ideas as the trial. CDC says it is "proven to cut type 2 diabetes risk in half" (CDC, National DPP).
The program focuses on building habits meant to last over the long term, not a quick fix. It follows the same direction as the trial: steady activity and modest, lasting change.
- Ask your clinician or local health department about a recognized program.
- Ask your health plan or employer whether it is covered.
- Pick a format you will stick with for a full year.

What steps should you take after a prediabetes result?
Five steps, in the order most people find useful.
Confirm the number
Ask which test it was and whether a repeat test makes sense. Keep a copy of the lab report.
Set one activity goal
Work toward 150 minutes a week. Start where you are, even with 10 minutes.
Pick a modest weight goal
If weight loss is right for you, 7% was the trial's target. Gentle, steady change counts.
Join a structured program
A yearlong program gives habits time to stick. Ask about the CDC-recognized program.
Recheck on schedule
Agree on when to repeat your A1C or fasting glucose, and put it on the calendar.
Some people also ask about metformin. It lowered risk by 31% in the trial (NIDDK, DPP), and only a clinician can decide whether it fits you.
Supplements
Do supplements help with prediabetes?
Not on current evidence. The ladder shows how much testing each option has behind it.
- 4Guidelines and large trials
- 3Several trials
- 2Small human trials
- 1Lab and animal studies
- GlucoZen's blendNo trials found(FDA, Dietary supplements Q&A)
- Chromium, gymnema, ginsengSmall, mixed trials(NIH ODS, Chromium) (LiverTox, Gymnema) (NCCIH, Asian ginseng)
- Metformin (prescription)Large trial: 31% lower risk(NIDDK, DPP)
- Lifestyle programLarge trial: 58% lower risk(NIDDK, DPP) (CDC, National DPP)
Higher means stronger evidence for preventing or managing type 2 diabetes. In the Diabetes Prevention Program, the lifestyle program beat metformin; no supplement was tested.
Under Recommendation 5.16 of the ADA's 2026 Standards of Care, micronutrient, herb and spice supplements are not advised for glucose benefit (ADA, Standards of Care 2026). The ADA also says supplements are not proven to lower blood glucose (ADA, Vitamins and supplements). Supplements also reach shelves without FDA approval, since FDA lacks that authority for them (FDA, Dietary supplements Q&A).
That gap is the reason a supplement cannot stand in for the steps above. See every option side by side on the comparison page.
Where GlucoZen fits
Can GlucoZen help with prediabetes?
No study has tested GlucoZen in people with prediabetes, or in anyone. Its label says "Blood Sugar Support," and that is a brand claim, not a finding.
A 1 mL serving lists chromium at 0.7 mcg plus a 200 mg blend holding 22 herbs and amino acids. At the label's 1 mL twice daily, chromium comes to 1.4 mcg a day, about 4% of the Daily Value (NIH ODS, Chromium).
If you choose to try it, treat it as an extra next to the lifestyle steps, never in place of them. Read the line-by-line Supplement Facts first, and check the who it's for limits.
When to call
When should someone with prediabetes call a clinician?
Call if a new result lands in the diabetes range, or if you notice extreme thirst or confusion. Very high readings with those signs need prompt care.
Insulin, sulfonylureas and meglitinides can cause lows, often defined as below 70 mg/dL, with shakiness, hunger or dizziness (NIDDK, Hypoglycemia). Treat a low right away and tell your care team before adding any supplement.
FAQ
Prediabetes questions, answered
What A1C level is considered prediabetes?
An A1C of 5.7% to 6.4% falls in the prediabetes range for adults who are not pregnant, according to NIDDK. Under 5.7% is normal, and 6.5% or higher is in the diabetes range. Clinicians usually confirm a diabetes-range result with a second test before making a diagnosis.
Can you keep prediabetes from turning into type 2 diabetes?
Many people can lower their chances a lot. In the Diabetes Prevention Program, a lifestyle program with 7% weight loss and 150 minutes of weekly activity cut the chance of type 2 diabetes by 58% over about 3 years. It lowers risk; it does not promise a result for every person.
How much weight should I lose if I have prediabetes?
The Diabetes Prevention Program aimed for about 7% of body weight. For a 200 pound person that is 14 pounds. Talk with your clinician about whether weight loss suits you, since activity, sleep and eating patterns also matter, and the right goal depends on your health.
How long does the CDC diabetes prevention program last?
The CDC National Diabetes Prevention Program runs for a year. CDC describes it as a lifestyle change program built around habits meant to last, and says it cuts type 2 diabetes risk in half. Ask your clinician, health plan or local health department how to join one.
How many people in the U.S. have prediabetes?
CDC estimates that 115.2 million U.S. adults aged 18 and older have prediabetes. The same report counts 40.1 million people with diabetes in 2023, including 11.0 million adults who did not know they had it. Many people with prediabetes have no symptoms.
Is there a supplement that reverses prediabetes?
No supplement has been shown to do that. The ADA's 2026 Standards of Care do not recommend chromium, magnesium, herb or spice supplements for blood sugar benefit. GlucoZen has no published trial. The steps with real evidence are activity, modest weight loss and a structured lifestyle program.
Did metformin work in the Diabetes Prevention Program?
Yes, it helped, though less than lifestyle change. Metformin lowered the chance of type 2 diabetes by 31% over about 3 years, compared with 58% for the lifestyle program. Metformin is a prescription drug, so only your clinician can say whether it fits your situation.
