Vitamin C
If you tell someone you are on a meat only diet, they will be quick to ask you where you get your Vitamin C - because, as everyone knows, you will get scurvy without it.
This is not the case. Essentially glucose will interfere with the uptake of vitamin C. If you don't have excess blood sugar, say from a high carb diet, you will not need much vitamin C.

Zsofia Clemens and Csaba Tóth discuss it in this wonderful article
"We put forward that instead of taking vitamin C as a supplement, an evolutionary adapted human diet based on meat, fat and offal would provide enough vitamin C to cover physiological needs and to ward off diseases associated with vitamin C deficiency."

Vitamin C is used in the synthesis of collagen through the combination of hydroxy groups with lysine and proline. Meat contains hydroxylysine and hydroxyproline.
The reason sailors developed scurvy is because they ate nothing but hardtack for months, which is wheat grain biscuits with the consistency of a boulder. That's sugar and antinutrients with zero bioavailable vitamins. Further, these dolts didn't think to catch fish because they thought grains were enough to keep them fed.
Their scurvy was a result of meat deficiency, not plant deficiency. All plant vitamins needed in bodily processes are not necessary because meat contains the pre-formed tissues and nutrients which does, indeed, digest into the base components but in a pre-formed state.

Vitamin C and Disease: Insights from the Evolutionary Perspective
Abstract
The role of vitamin C at the physiological and cellular levels is indisputable. In line with this, blood level of vitamin C is inversely related to disease parameters such as risk of cancer, cardiovascular disease and mortality in prospective cohort and correlational studies. At the same time, adequately powered clinical intervention studies consistently provide no evidence for a beneficial effect of supplementing vitamin C. Here we provide a framework to resolve this apparent conflict. Besides providing an overview of the widely-known facts regarding vitamin C, we review evidence that are of potential relevance but are seldomly mentioned in the context of vitamin C. We invoke the glucose-ascorbate antagonism (GAA) theory which predicts that as a consequence of their molecular similarity glucose hinders the entry of vitamin C into cells. Integrating data coming from research at the cellular level, those from clinical, anthropological and dietary studies, in the present hypothesis paper we propose an evolutionary framework which may synthesize currently available data in the relation of vitamin C and disease. We put forward that instead of taking vitamin C as a supplement, an evolutionary adapted human diet based on meat, fat and offal would provide enough vitamin C to cover physiological needs and to ward off diseases associated with vitamin C deficiency.
