I have addressed this point elsewhere in this thread, and it has also been explained ten thousand times on forums such as https://reddit.com/r/carnivore

The long and the short of it is that fresh meat contains vitamin C and the carnivore diet also reduces your body's need for vitamin C because vitamin C is used for the synthesis of collagen and you will be getting collagen directly by following this diet.

Ah never knew meat contains vitamin c, seems to be mostly in the liver.

Well it's an interesting experiment going on meat and see how the body responds.

yes, beef liver is the most nutritious thing you can eat on Earth, bar none. But there are some carnivores who only eat ribeye steaks and do not eat the organ meats -- and they don't get scurvy.
