Is Muscle Health PLUS vegan?

Muscle Health PLUS is not 100% plant-based. Currently, the l-leucine is derived from an animal source. With that said, our team continues to look for a plant-based form of l-leucine that performs as well as the animal-derived version. Note that l-leucine is the only animal-derived ingredient in the product, so if we're able to swap this ingredient, the product would become 100% plant-based and vegan.
