I haven't heard of it. We use Stevia. I carry tons of these packets in my purse so when we eat out and have iced tea we have our own sweetner. It's 100% Natural. Calorie Free, sugar free and doesn't contain soy, wheat, yeast, milk or artificial ingredients of any kind. Natural herb, saccharin- free, aspartame-free and no after taste. We get it at Trader Joe's. |
