More than one third of people in the developed world have metabolic syndrome, an insulin-resistant state in which borderline high blood sugar and other metabolic abnormalities indicate an increased risk for serious health conditions such as heart disease, stroke, cancer and other ageing diseases.

Sugar-lowering drugs are not usually prescribed by doctors until a person has diabetes, which means many people are in a dangerous pre-diabetic state without any prevention treatments.

Natural supplements have demonstrated that they are able to help reduce the risk by lowering blood sugar.

These include cinnamon, chromium, alma, shalajit and seaweed and should be used to help maintain healthy blood sugar levels.
