Reign is a pretty new product quickly gaining popularity.
Their website is pretty barebones for now, just explaining that it’s a pre-workout supplement with BCAAs, caffeine, CoQ10, and electrolytes.
BCAAs in general are sometimes vegan, but not always.
I contacted the company about whether or not it’s vegan, and got back a pretty standard templated response:
Thanks again for taking the time to contact us.
We use no animal bi-products in any of our product lines. However, the product is not vegan certified.
That’s as clear as it gets, Reign is vegan.
You can also check out Reign’s Twitter account, they constantly re-tweet posts from vegans about the product. That’s another good indication.
If this changes in the future, I will try to keep this page updated.
