Low GI sugar substitutes are a range of sweeteners that are designed to provide a healthier alternative to traditional sugar. These products are made from natural ingredients and have a low glycemic index, which means they are absorbed more slowly by the body and do not cause rapid spikes in blood sugar levels. They are ideal for anyone looking to reduce their sugar intake or for those with diabetes who need to control their blood sugar levels. These products come in a variety of forms, including granulated sweeteners, liquid sweeteners and syrups, and can be used in a range of recipes and drinks.
