Sweet 10 is a liquid sugar substitute that has no calories or carbohydrates. It is made from sodium saccharin, which is about 300 times sweeter than regular sugar. This sugar substitute is hard to find, as it is no longer sold in local grocery or health-food stores. However, there are a couple of online stores that still carry this product.
This website still carries Sweet 10. A 6-oz. bottle sold for less than $3 in August 2009.
Amazon carries just about anything, including Sweet 10. Amazon sells 6-oz. bottles in packs of six or 12. If a product is out of stock on Amazon, you can sign up to be notified when it is available.
As you can see, Sweet 10 sugar substitute is difficult to obtain and available on only a couple websites. Therefore, the sites that do sell it may have a difficult time of keeping it in stock. Check these websites regularly if you don't want to miss an opportunity to purchase this product.
