Fruitflow is an ingredient added to other foods or beverages in the form of 'Fruitflow l' which is a 'tomato-based syrup', and it is offered in a non-sugar containing powder called 'Fruitflow II' which can also be added to foods and as a supplement apparently.
I have not read any of the 10 human studies they report, but the one they show a graphic from on the website of the ingredient maker was looking at just 26 some odd subjects. It may be useful, but I imagine the studies are rather skimpy from this first example.
Nonetheless, it may well be worth exploring with a healthy dose of an open-minded, yet appropriately skeptical perspective.
