The problem
Your glucose is telling you something
Same food. Same routine. Feeling different?
After age 35, metabolic changes can quietly accelerate. Your body’s cells can become less efficient at processing glucose. Meals that were steady before now start spiking your glucose levels. The problem isn't a lack of willpower; it’s that you've been flying blind on how your body is changing. Real-time glucose insights can help you adjust your habits and daily routines as you age.

What is A1c?
A1C is a blood test showing your average blood sugar levels over about the past 3 months.4 Unlike a single glucose reading capturing a single moment in time like a fingerstick, A1C provides a bigger picture view of your recent glucose health. It’s commonly used to test for prediabetes and to check glucose health over time with your doctor.

Know your A1c. Know your risk.
Current expert guidelines recommend a blood test for prediabetes or diabetes screening beginning at age 35. Risk factors like overweight, obesity, family history, or high blood pressure increase the risk. The earlier prediabetes is identified, the earlier action can begin. Lifestyle changes to food and exercise habits along with weight loss have been shown to reduce the progression to type 2 diabetes by 58% over about 3 years.
