Ginger contains bioactive compounds capable of controlling blood sugar, such as gingerol and shogaol, which can help muscle cells absorb blood glucose more effectively, thereby increasing insulin sensitivity. This is a very important factor in helping to control blood sugar, according to the health site Medical News Today (UK).

These compounds are also believed to inhibit certain enzymes related to carbohydrate digestion and possess anti-inflammatory properties, helping to reduce oxidative stress. These are the very factors that contribute to insulin resistance.
Some research evidence shows that consuming ginger regularly can help improve blood sugar in people with type 2 diabetes and prediabetes. For instance, a study published in the journal Nutrients found that ginger helps reduce fasting blood sugar levels in people with high blood sugar.
In human clinical trials, ginger is typically used in doses ranging from 1.2 to 3 grams/day for a duration of 4 to 12 weeks.
Meanwhile, in healthy individuals or those just wanting to take preventive measures, evidence shows that eating ginger regularly does not bring about clear blood sugar stabilizing effects as it does in those with diabetes.
Ginger can cause some symptoms such as heartburn or discomfort in the digestive tract. These issues are usually mild. Ginger rarely causes severe side effects. However, this does not mean it can be used in large amounts arbitrarily. Ginger can increase the risk of bleeding when used together with anticoagulants or antiplatelet drugs like aspirin or warfarin.
Additionally, when combined with blood-sugar-lowering medications or insulin, high doses of ginger can increase the risk of excessively low blood sugar. Therefore, people who are treating diabetes with medication need to consult with their doctor before using ginger regularly.
One thing to note is that ginger has a supportive effect but cannot replace a healthy diet, regular exercise, and adherence to a doctor's treatment regimen. Therefore, the best way is to combine ginger with other blood sugar control measures rather than using it as a standalone solution, according to Medical News Today.
