Blood sugar basics
Prediabetes: What It Means and What Actually Helps
Prediabetes means blood sugar is higher than normal but not yet in the diabetes range. NIDDK counts about 97.6 million U.S. adults with it in 2021, and CDC says a lifestyle change program cut type 2 diabetes risk by 58%. Supplements, Glyco Reset included, are not part of that proven plan.

The basics
What does prediabetes mean?
Prediabetes means your blood sugar is above the normal range but below the level used to diagnose type 2 diabetes. It is common, it often has no symptoms, and it can change.
NIDDK, part of the National Institutes of Health, says about 97.6 million U.S. adults had prediabetes in 2021 (NIDDK: Prediabetes & insulin resistance). CDC puts it another way: more than 2 in 5 American adults have it (CDC: Prediabetes, prevent type 2). Most of them do not know.
The word "pre" matters. It is a warning light, not a verdict.
The exact test numbers that define prediabetes come from your doctor and the lab. We do not list cutoffs here, because your doctor reads them in the context of your age, health and other results.
How it happens
What is insulin resistance, and how is it linked to prediabetes?
Insulin resistance means the body's cells do not respond well to insulin, the hormone that moves sugar from the blood into cells. NIDDK covers insulin resistance and prediabetes on the same page because they are closely tied (NIDDK: Prediabetes & insulin resistance).
When cells push back, the pancreas makes more insulin to keep up. For a while that works. Over time, blood sugar can start to creep up, and that is when a blood test may show prediabetes.
A quick note on tests. A fasting glucose test measures sugar in your blood after you have not eaten for several hours. An A1C test reflects your average blood sugar over the past few months. Your doctor decides which test you need and what your results mean.
The numbers
How many people have prediabetes, and what lowers the risk?
Two federal sources give the core numbers, and they agree on the main point: lifestyle change works for many people. The table keeps each figure next to its source.
| Figure | What it says | Source |
|---|---|---|
| 97.6 million | U.S. adults with prediabetes in 2021 | NIDDK (NIDDK: Prediabetes & insulin resistance) |
| More than 2 in 5 | American adults who have prediabetes | CDC (CDC: Prediabetes, prevent type 2) |
| 5% to 7% | Weight loss from starting weight that helped high-risk people in the Diabetes Prevention Program | NIDDK (NIDDK: Prediabetes & insulin resistance) |
| 58% | Lower type 2 diabetes risk with the National Diabetes Prevention Program lifestyle change program | CDC (CDC: Prediabetes, prevent type 2) |
| 71% | Lower risk in people over 60 in the same program | CDC (CDC: Prediabetes, prevent type 2) |
No supplement appears in this table. The proven results came from changes in weight, food and activity, with support from a structured program.
What helps
What lifestyle steps have evidence behind them?
The strongest evidence points to a structured lifestyle program and modest weight loss. In the Diabetes Prevention Program, losing 5% to 7% of starting weight helped high-risk people lower their chance of type 2 diabetes (NIDDK: Prediabetes & insulin resistance).
Ask about a lifestyle change program
CDC's National Diabetes Prevention Program is the program behind the 58% figure (CDC: Prediabetes, prevent type 2). Ask your doctor or local health department how to join one.
Set a small weight goal, if your doctor agrees
The 5% to 7% range NIDDK cites is a modest target, not a crash diet.
Build movement into most days
Physical activity is part of the lifestyle program CDC describes. A walk after a meal is an easy place to start.
Watch added sugar
The Dietary Guidelines for Americans 2025-2030 say added sugars "are not recommended" (Dietary Guidelines 2025-2030 (RealFood.gov)). Read labels, including on supplements.
None of these steps needs a special product. More habits are in the blood sugar guide.
Testing
When should you get tested for prediabetes?
Ask your doctor about a blood sugar test at your next checkup, especially if you have never had one. Because prediabetes rarely causes symptoms, waiting to feel unwell is not a reliable plan.
Your doctor can choose between tests such as fasting glucose and A1C, and can tell you how often to repeat them. The right schedule depends on your health history, your weight, your family and any medicines you take.
Questions worth bringing to the visit
- Which test are you ordering, and what does my result mean?
- How often should I be retested?
- Is there a lifestyle change program near me or online?
- What weight goal makes sense for me?
- Should I tell you about any supplements I take or plan to try?
That last question matters. FDA notes that some supplements interact with medicines (FDA 101: Dietary supplements), and RxList lists vinegar interactions with insulin and diabetes medicines (RxList: ACV interactions). See medicines and Glyco Reset.

Where do supplements fit for prediabetes?
For most supplements, the evidence is thin. The National Center for Complementary and Integrative Health says that "for most supplements, there isn't evidence to support a beneficial effect on diabetes or its complications" (NCCIH: Diabetes and dietary supplements).
NCCIH adds that it is very important not to replace medical treatment for diabetes with an unproven product or practice (NCCIH: Diabetes and dietary supplements). The American Diabetes Association goes further: its Standards of Care do not recommend supplements unless a nutrient deficiency has been diagnosed (ADA: Vitamins & supplements).
If you take diabetes medicine, never stop or change it because of a supplement. Talk to your doctor before adding anything new.
FDA does not approve dietary supplements for safety or effectiveness before they are sold (FDA 101: Dietary supplements). A product that claims to treat or prevent a disease is regulated as a drug, even if its label says "supplement."
About our product
Is Glyco Reset a treatment for prediabetes?
No. Glyco Reset is a dietary supplement in liquid drops, not a drug and not a treatment for prediabetes or diabetes. The brand describes it as "Supports Healthy Glucose Utilization*," and the asterisk means FDA has not evaluated that claim.
Its main named ingredient is apple cider vinegar. In a pooled analysis of 9 trials with 686 people, vinegar was linked to fasting glucose about 7.97 mg/dL lower and no change in insulin resistance scores (Hadi 2021 ACV meta-analysis). Those trials used about 15 to 30 mL of vinegar a day.
A Glyco Reset bottle holds 60 mL of everything combined, and the vinegar per serving is not published. The formula also lists pure cane sugar, amount not published. See the ingredients page for each one.
Bottom line
What is the takeaway on prediabetes?
Prediabetes is common and often silent. A blood test finds it. Modest weight loss and a structured lifestyle program have the strongest evidence, with risk cut by 58% in CDC's program (CDC: Prediabetes, prevent type 2).
Supplements sit at the edge of that plan, not the center. If you are comparing products, our guide on choosing a blood sugar supplement lists what to check.
FAQ
Prediabetes questions people ask
Can prediabetes go away?
It can improve for many people. In the Diabetes Prevention Program, losing 5% to 7% of starting weight helped high-risk people lower their chance of type 2 diabetes, per NIDDK. Your doctor can retest you to see whether your numbers have moved back toward normal.
How common is prediabetes in the U.S.?
Very common. NIDDK reports about 97.6 million U.S. adults had prediabetes in 2021, and CDC says more than 2 in 5 American adults have it. Many people with prediabetes do not know, because it rarely causes symptoms.
What is the difference between insulin resistance and prediabetes?
Insulin resistance means cells respond poorly to insulin, so the body needs more of it. Prediabetes means blood sugar has risen above normal but not into the diabetes range. NIDDK covers them together because insulin resistance often comes first.
Does a lifestyle program really work for prediabetes?
The data are strong. CDC says its National Diabetes Prevention Program lifestyle change program can lower type 2 diabetes risk by 58%, and by 71% for people over 60. Ask your doctor how to join a program in person or online.
Can a supplement help with prediabetes?
The evidence is weak for most products. NCCIH says most supplements lack evidence of benefit for diabetes, and the ADA does not recommend supplements unless a deficiency has been diagnosed. Never use one in place of your doctor's plan.
Is Glyco Reset safe to take with prediabetes?
Ask your doctor first. Glyco Reset lists apple cider vinegar, which RxList says can interact with insulin, diabetes medicines, digoxin and diuretics. The formula also lists pure cane sugar, and no amounts or dose are published online, so follow the label you receive.
