L Carnitine
 

I generally take this supplement when training for a marathon. However I have noticed on the label that it is not suitable for vegetarians/vegans.
Holland and Barrett do a similar product with the same ingredients which they claim is suitable for vegetarians/vegans and various vegetarian/vegan websites say it's ok for vegetarians/vegans to take this supplement .
The product I'm using is from myprotein.com. Are they just being over cautious or can it be manufactured in different ways?

You can find vegan carnitine supplements, but you should check out these studies before you do-
