Hi Jake 43241,
I actucually use the product that you are refering to. I have contacted the company and they don’t give the properties of natural flavor. I did explain our concern with that food ingredient. She is going to look in to it and call me. I will post the info. The number to call the company is 1-888-820-9283. I am a diabetic and it can be difficult to find products that are beneficial for me. I use the product and will continue to do so. Kefir is also a healthy refreshing beverage. It can be purchased from Cultures for Health. They are great grains and the people at the company don’ mind answering quesions. I make mine with coconut milk as I have difficulties with milk. Hope this helps you out.
