“It should be noted that although creatine is found mostly in animal products, the creatine in most supplements is synthesized from sarcosine and cyanamide [39,40], does not contain any animal by-products, and is therefore “vegan-friendly. The only precaution is that vegans should avoid creatine supplements delivered in capsule form because the capsules are often derived from gelatin and therefore could contain animal by-products.”
On (1), I commented above, but most supplemental creatine is vegan as far as I can tell.
Thanks, I’m seeing that here, too:
