Does Tart Cherry Juice Lower Blood Sugar? Science-Backed Facts
Tart cherry juice may help lower blood sugar levels due to its antioxidants and anti-inflammatory properties, but more research is needed for conclusive evidence.
Tart cherry juice has gained popularity as a natural remedy for various health issues, including blood sugar management. Packed with antioxidants, vitamins, and anti-inflammatory compounds, this vibrant red juice may offer benefits for glucose control. But how strong is the evidence?
