Elevated glucose levels are especially detrimental as they can lead to diabetes, cardiovascular disease, kidney dysfunction, and eye disorders.
A healthy, balanced diet is the foundation of hyperglycemia intervention and prevention. This includes an abundance of micronutrients, antioxidants, and anti-inflammatory compounds from fruits, vegetables, nuts, herbs, and spices.
These beneficial compounds can be consumed within the diet or supplemented when appropriate.
Culinary herbs and spices that have been most researched for their beneficial effects on blood glucose regulation and cardiometabolic health include (Mackonochie 2023).
Omega-3 Polyunsaturated Fatty Acids

Phytogenic substances as possible options for obesity and diabetes therapies are shown.

The herb Gymnema sylvestre can significantly improve blood glucose control and is known as gurmar, meaning “destroyer of sugar” in Hindi/Ayurvedic medicine (McKennon 2021). A systematic review and meta-analysis of data from 419 type 2 diabetic subjects across 10 research studies concluded that Gymnema sylvestre significantly reduced fasting glucose, postprandial glucose, hemoglobin A1C, triglycerides, and total cholesterol (Devangan 2021)
Gymnema sylvestre supplementation may reduce insulin and type 2 diabetes requirements and even stabilize blood glucose following the discontinuation of these drugs in some individuals (Rahman 2022).
