Sugar Defender is a dietary supplement designed to help manage blood sugar levels and curb sugar cravings. While it offers several benefits, it's essential to be aware of potential side effects. Common side effects include gastrointestinal issues such as bloating, gas, and diarrhea due to high fiber content or other ingredients aimed at regulating blood sugar. Some users may experience mild headaches or dizziness, particularly when starting the supplement, as the body adjusts to changes in blood sugar levels. Allergic reactions, though rare, can occur, leading to symptoms like itching, swelling, or difficulty breathing. It's crucial to consult with a healthcare professional before beginning any new supplement, especially for individuals with underlying health conditions or those taking other medications. Monitoring for adverse effects and adjusting dosage as necessary can help mitigate these side effects.
