“Knowing my glucose means no more guessing.
It’s all based on data. My data.”
– Serena Williams
When one game-changer meets another
Thanks to Lingo, Serena’s figured out that staying in a healthy glucose range** isn’t about achieving perfection. It’s about noticing the patterns and habits that support her goals (and the ones that don’t).
Just like Serena, your body is unique. When you get to know your glucose, you gain insights that can help support your metabolic health, now and in the future.
**A typical glucose range for healthy individuals is 70-140mg/dL. Occasionally, one may find themselves over 140 mg/dL or under 70 mg/dL, which is expected.
