Soy Protein

Question

GNC makes an isolated soy protein mix called Soy Protein 95. There is no kashrut on it at all. It is vegetarian, and the only ingredient is Supro Brand Soy Protein Isolate. Is it kosher? They also make a chocolate-flavored Soy Protein 95. The ingredients are: Supro Brand Soy Protein Isolate, Cocoa, Fructose, Natural and artificial flavor, salt, acesulfame potassium, and sucralose. Is it kosher? Thank you
