The carnivore diet is a controversial topic, and one of the most persistent concerns is whether individuals will get enough vitamin C. This worry is based on the misconception that plants are the only source of vitamin C. In reality, meat does contain small amounts of vitamin C, and proponents of the carnivore diet argue that this is sufficient to prevent vitamin C deficiency and scurvy. Some sources suggest that organ meats, such as beef spleen, pork liver, and beef liver, can provide even higher amounts of vitamin C. However, critics argue that a carnivore diet may not provide optimal levels of vitamin C and that additional supplementation or the inclusion of fruits and vegetables may be beneficial. While there is conflicting evidence, it is clear that the carnivore diet requires careful consideration of nutrient intake to ensure overall health.

Meat contains vitamin C
The idea that a carnivore diet leads to vitamin C deficiency and scurvy is based on the misconception that plants are the only source of vitamin C. This fallacy has been perpetuated by the USDA, which lists vitamin C amounts in muscle meat as "assumed to be zero". However, research published in the Meat Science Journal in 2007 contradicts this, finding that fresh beef contains approximately 1.6 mcg/g of vitamin C in grain-fed meat and 2.56 mcg/g in grass-fed meat.
On a carnivore diet, consuming 1000 grams of meat per day would provide 2.56 mg of vitamin C from grass-fed beef and 1.6 mg from grain-fed beef. This exceeds the amount of vitamin C needed to prevent scurvy, which is only about 10 mg per day. In fact, for over 100 years, it has been known that fresh meat not only prevents but cures scurvy.
While it is true that vitamin C is concentrated in internal organs and brain rather than muscle meat, adding organ meats to your diet can boost your vitamin C intake. For example, raw liver, fish roe, and eggs are good sources of vitamin C. Additionally, when you reduce carbohydrates, your body absorbs more vitamin C as they compete for the same metabolic pathways.
It is worth noting that cooking meat can lead to significant vitamin C loss due to its instability when exposed to water, air, light, heat, and pH levels above 4.0. To minimize this loss, meat can be consumed raw (fresh or frozen) or after it has been putrefied, which also lowers the pH and increases vitamin C stability.
In summary, meat does contain vitamin C, and a varied carnivore diet that includes fresh meat and organ meats can provide sufficient vitamin C to prevent deficiency and maintain optimal health.

Organ meat is a good source of vitamin C
The carnivore diet has sparked concerns about potential vitamin C deficiencies, but these worries are largely unfounded. While vitamin C is essential for various bodily functions, including collagen formation, it is a common misconception that plants are the only source of this nutrient. Organ meats, such as beef spleen, pork liver, and beef heart, are excellent sources of vitamin C, providing sufficient amounts to prevent deficiencies and associated health issues like scurvy.
Vitamin C is indeed vital for our health, but the belief that a meat-only diet leads to vitamin C deficiency stems from a fallacy. This misconception likely arose from observing the diets of British sailors, who consumed primarily dried meat and carbohydrates, which are low in vitamin C. However, fresh meat, especially organ meat, has been scientifically proven for over a century to not only prevent but also cure scurvy, a disease caused by vitamin C deficiency.
Organ meats, such as liver and beef spleen, are particularly rich in vitamin C. For example, 100 grams of cooked beef spleen provides approximately 50.3 mg of vitamin C, which meets 84% of the average recommended daily intake. Additionally, a 6-ounce serving of oysters contains about 12 mg of vitamin C, and fish eggs, such as salmon roe, are also excellent sources, with a 3-ounce serving providing around 4.5 mg.
Consuming organ meats on a carnivore diet ensures adequate vitamin C intake. A survey by the Zero Carb Health community found that 90% of respondents who regularly included liver and other organ meats in their strict carnivore diets maintained healthy vitamin C levels. Furthermore, a study published in the journal "Nutrients" reported that participants on a carnivore diet who consumed organ meats did not exhibit vitamin C deficiency over a six-month period.
In conclusion, organ meat is a valuable source of vitamin C for those adhering to a carnivore diet. By incorporating these nutrient-dense foods, individuals can obtain sufficient vitamin C while reaping the health benefits and satisfaction often associated with the carnivore lifestyle.

Vitamin C requirements are lower on a carnivore diet
The concern that a carnivore diet may not provide sufficient vitamin C is generally rooted in the mainstream dietary belief that plants are the only source of vitamin C. However, this is a fallacy, as meat does contain small amounts of vitamin C. For example, muscle meat contains enough vitamin C to prevent scurvy (vitamin C deficiency). Traditional groups subsisting on meat-based diets, like the Arctic Inuit, did not suffer from scurvy, nor does the modern-day carnivore community.
Additionally, eating fish, seafood, and organs (such as beef spleen, pork liver, beef thymus) can further increase your vitamin C intake. In clinical practice, vitamin C has not been an issue for carnivore clients, indicating that the vitamin C naturally occurring in meat is sufficient.
However, it is important to note that the optimal amount of vitamin C for those on a carnivore diet is unknown. While some proponents of the carnivore diet claim that vitamin C supplementation is unnecessary, others argue that additional vitamin C may be beneficial for certain individuals, especially those healing from a serious chronic illness. Furthermore, a carnivore diet may not provide optimal levels of vitamin C for everyone.
Overall, while vitamin C requirements are lower on a carnivore diet, it is still essential to ensure adequate intake, as vitamin C plays a vital role in various bodily processes, including proper collagen formation.

No cases of vitamin C deficiency in the modern-day carnivore community
The concern about vitamin C deficiency in people on a carnivore diet is based on the mainstream belief that plants are the only source of vitamin C. However, this is a fallacy as meat, especially fresh meat, does contain vitamin C.
Vitamin C is an essential dietary nutrient, meaning our bodies cannot produce it and we need to consume it through our diet. While it is true that vitamin C is abundant in fruits and vegetables, it is also present in meat, albeit in smaller quantities. Carnivores need very little vitamin C, and the vitamin C found in meat is enough to meet their daily requirements.
According to some sources, eating at least 1000 grams (2.2 lbs) of fresh muscle meat per day on a carnivore diet will provide enough vitamin C to prevent scurvy (vitamin C deficiency). In fact, it is hypothesized that on a low-carb carnivore diet, you may need even less vitamin C as glucose and vitamin C compete for absorption, and when glucose is present in high amounts, it wins out.
Some proponents of the carnivore diet claim that there are no cases of vitamin C deficiency in the modern-day carnivore community. They argue that people have been eating this way for years, even decades, without any reported cases of scurvy. However, it is important to note that the data supporting these claims is mostly self-reported and anecdotal, and there is a lack of scientific research backing up these assertions.
Additionally, it is worth mentioning that while organ meats such as liver, kidney, spleen, and lung contain higher amounts of vitamin C than other meats, they are not always a part of everyone's carnivore diet. As a result, some people on a carnivore diet may be at a higher risk of vitamin C deficiency, especially if they are not consuming enough organ meats or other sources of vitamin C.
In conclusion, while there may be no reported cases of vitamin C deficiency in the modern-day carnivore community, it is important to approach this diet with caution. The lack of scientific research and the potential for nutrient deficiencies highlight the need for careful consideration and consultation with healthcare professionals before embarking on a carnivore diet.

Vitamin C is mostly used to digest carbohydrates
One of the most common concerns about the carnivore diet is whether it provides enough vitamin C to prevent scurvy. This concern is based on the misconception that plants are the only source of vitamin C, and that meat contains none. However, this is not true; meat does contain vitamin C, and when following a carnivore diet, all the vitamin C found in the meat is absorbed, providing enough to meet your daily requirements. In fact, eating 1000 grams (2.2 lbs) of fresh muscle meat will provide more than enough vitamin C to prevent scurvy.
Vitamin C is an essential nutrient, meaning our bodies cannot produce it and we must obtain it from our diet. While it is commonly associated with citrus fruits, vitamin C can also be found in animal sources, particularly the adrenal and thymus glands, brain, bone marrow, pancreas, liver, and kidney. These animal sources of vitamin C are often accompanied by a complex of other naturally occurring phytonutrients.
Vitamin C plays a vital role in various bodily processes, including the growth and repair of tissues, the production of collagen, and the functioning of the nervous, immune, bone, and cartilage systems. It is also a powerful antioxidant, helping to prevent and treat various health conditions such as cancer, cardiovascular disease, high blood pressure, asthma, and osteoarthritis.
While it is important to ensure adequate vitamin C intake, excessive supplementation may lead to adverse effects. The Recommended Dietary Allowance (RDA) for adults is 90 mg daily for men and 75 mg for women, with higher amounts suggested during pregnancy and lactation. The Tolerable Upper Intake Level (UL) for vitamin C is 2000 mg daily, and exceeding this amount may cause gastrointestinal issues and diarrhea. It is worth noting that the intestines have a limited ability to absorb vitamin C, and absorption decreases when taking amounts greater than 1000 mg.
Vitamin C is indeed important for carbohydrate metabolism. A deficiency in vitamin C has been shown to impact carbohydrate metabolism in guinea pigs, leading to changes in glycosuria, glucose tolerance, and liver glycogen content. However, this does not mean that vitamin C is primarily used for digesting carbohydrates. The carnivore diet is naturally low in carbohydrates, and as such, the demand for vitamin C in carbohydrate metabolism is reduced. Therefore, while vitamin C plays a role in carbohydrate metabolism, it is not the primary use of this nutrient on a carnivore diet.
