Do XTEND products contain Animal Derivatives?

In other words, are these vegan or vegetarian friendly?

XTEND BCAA products, such as Original, On The Go Carbonated, Ripped and Elite, utilize a 2:1:1 ratio of Leucine, IsoLeucine, and Valine. XTEND BCAAs may be derived from vegan and non-vegan sources depending on the available global supply of raw materials. Out of these three, Leucine is the most common non-vegan, animal byproduct amino acid. IsoLeucine and Valine are commonly plant-based ingredients via corn glucose fermentation. To maintain the highest quality and most readily available raw materials, XTEND may dually source vegan or non-vegan BCAA ingredients as necessary. It is for these reasons that XTEND BCAAs are not certified or marketed as vegan/vegetarian.

Most importantly, our amino acid raw materials do not originate from bovine or porcine materials or byproducts.
