Amber Dark Nectar is extracted from Mexico's agave plants. Our Agave Nectar is certified organic and has a low glycemic index making this sweetener a healthy alternative. Agave is the perfect sweetening option for those concerned with sugar in their diet or with cutting empty carbohydrates. Agave is superior to sugar because sugar is a processed sweetener that has no nutritive value, other than calories. And agave has a desirable low–glycemic index. This means that when consumed, it won't cause a sharp rise or fall in blood sugar. USDA – Organic.
