How to verify any supplement

• Look for a clear company name, contact details and a written refund policy.
• Be wary of claims to cure disease, countdown timers and 'secret' ingredients.
• Check the ingredients against independent sources such as the NIH.
• Use only the official checkout so the guarantee applies.

The honest context

Some ingredients in blood-sugar formulas, such as berberine or cinnamon, have shown modest effects on glucose in small studies, but no supplement replaces diabetes medication, diet and exercise. Stopping prescribed treatment in favour of a supplement can be dangerous.

Very high or very low blood sugar, confusion, extreme thirst or fainting needs urgent medical care.
