⚠️ If you have diabetes, always consult your doctor or a registered dietitian before changing your diet. This recipe is not medical advice. Continue to monitor your blood sugar and observe your body's response.

Q2. How can I reduce the bitterness of bitter melon juice?: Three effective methods are: ① thoroughly remove seeds and white pith, ② massage with salt, let sit for 5 minutes, then rinse, and ③ add more green apple or lemon. Gradually increase the amount of bitter melon as you get used to the taste.
Q3. How much cinnamon should I consume for it to be effective?: Studies have reported improved blood sugar control with a daily intake of 1-6g of cinnamon. Start by consuming 1/4 teaspoon (approx. 0.6g) daily. Ceylon cinnamon is considered safer than Cassia cinnamon.
