It seems like thermogenic supplements just can’t catch a break. Like each main ingredient eventually turns out not to be safe. First it was ephedra (aka ephedrine), which was banned in the US. Then there was DMAA (dimethylamylamine): supplements containing it were pulled and some reportedly seized. Yet another ingredient seems to in trouble.
One for the top US dietary supplements manufacturers, USPLabs, is recalling two energy and fat loss supplements. Like ephedra and DMAA based supplements, these too appear to be quite popular especially in the bodybuilding circles.

The other USPLabs supplement in the recall is called VERSA-1. Both Oxyelite Pro and VERSA-1 contain the same main ingredient, known as aegeline. According to Wikipedia, aegeline is a constituent of the bael leaf, from a tree with a similar name that bears an edible fruit.
Interestingly, it was the US military that first brought attention to the safety of both DMAA and aegeline.

The difference between aegeline and DMAA, it appears, is that aegeline is natural while DMAA is not (though it was being marketed as natural). This proves, again, our standpoint that not everything that is natural is safe. Ephedra is natural as well.
Another interesting fact is that when DMAA issues started, supplements manufacturers scrambled to find an alternative. One alternative they found happens to be aegeline. Next?
