Registered dietitians often highlight tart cherry juice as a beneficial late-night drink for blood sugar management. The key is choosing an unsweetened, 100% juice variety to avoid added sugars that can cause spikes. Tart cherries are a natural source of melatonin, which regulates sleep, and anthocyanins, antioxidants linked to improved insulin sensitivity.
Research, including a 2022 review in Nutrients, indicates that the bioactive compounds in tart cherries can help reduce post-meal glucose and insulin levels. A consistent sleep schedule supported by melatonin may also improve metabolic health. However, dietitians emphasize that this juice is a complementary strategy, not a replacement for a balanced diet, regular exercise, or prescribed diabetes medication.
Portion control is critical; a typical serving is 4 to 8 ounces (120-240 ml). Consuming it about 30-60 minutes before bed may aid sleep quality and next-morning fasting glucose. Individuals with diabetes should consult their healthcare provider before making dietary changes.
