The ketogenic diet is a popular, low-carb regimen that limits carbohydrate intake to 25-50 grams a day. While the diet is inherently nutrient-dense, it can lead to deficiencies in certain nutrients, including vitamin C. Humans do not possess the enzyme required to produce vitamin C, so it must be obtained through diet or supplementation. Although vitamin C is commonly found in plant foods, there are keto-friendly sources such as colourful bell peppers, kale, cauliflower, broccoli, and Brussel sprouts. Meat is also a source of vitamin C, although there is debate over the amount present. Some studies suggest that a ketogenic diet may lead to lower vitamin C levels, while others indicate that ketosis reduces the need for vitamin C. Therefore, it is important for those on a ketogenic diet to be mindful of their vitamin C intake and consider supplementation if necessary.

Humans cannot produce vitamin C, so it must be obtained from food or supplements
Humans are unable to produce vitamin C. Unlike other animals, such as dogs and cats, we lack the enzyme necessary for its production. As a result, we must obtain this essential nutrient through our diet or supplementation.
Vitamin C is a water-soluble vitamin, which means the body cannot store it. It is commonly found in plant foods, including parsley, kale, cauliflower, broccoli, Brussel sprouts, and bell peppers, as well as liver and organ meats. While the ketogenic diet is nutrient-dense, it restricts carbohydrate intake, which can lead to a lower intake of vitamin C. Carbohydrates often contain water-soluble vitamins like vitamin C, and reducing their consumption may lower vitamin C levels.
To prevent vitamin C deficiency, those on a ketogenic diet can include vitamin C-rich foods, such as colorful bell peppers, kale, cauliflower, and broccoli. These vegetables are not only rich in vitamin C but also provide other health benefits. For example, diets high in cruciferous vegetables have been linked to a reduced risk of certain cancers. Additionally, supplements can help fill nutritional gaps, ensuring adequate vitamin C intake.
It is important to note that some studies suggest a link between low-carb diets and decreased vitamin C levels. However, other research indicates that ketogenic diets may result in higher vitamin C levels compared to moderate-carb diets. The reason for this discrepancy may be due to the competition between glucose and vitamin C for absorption, with glucose taking priority. As such, reducing carbohydrates may lead to improved vitamin C absorption and upregulation of endogenous antioxidants.
In summary, while humans cannot produce vitamin C, it is a crucial nutrient that can be obtained through a well-planned ketogenic diet that includes vitamin C-rich foods or through supplementation.

The ketogenic diet is low-carb, so vitamin C needs are lower
The ketogenic diet is a low-carbohydrate regimen that limits carbohydrate intake to 25-50 grams per day. It is a high-fat, low-carb, and moderate-protein diet that forces the body into a state of nutritional ketosis, where fatty acids are burned for fuel. While the ketogenic diet is inherently nutrient-dense, it can lead to nutrient deficiencies, including vitamin C deficiency.
Vitamin C is a water-soluble vitamin that humans must obtain from their diet or supplementation as they do not contain the enzyme needed for its production. The body maintains vitamin C in high amounts in white blood cells, skin, eyes, brain, and adrenal glands. It is commonly recommended by doctors and health experts as a treatment for infection and chronic illnesses. It can also enhance wound healing, aid in creating neurotransmitters, and protect against environmental pollutants and signs of aging.
The ketogenic diet may reduce the need for vitamin C because lowering carbohydrate intake lowers the need to supplement with vitamin C. This is because glucose and vitamin C compete for absorption into cells, and when glucose levels are low, the body absorbs more vitamin C. In addition, a study by F. T. McSwiney and colleagues found that endurance athletes following a low-carbohydrate ketogenic diet for 12 weeks experienced a significant drop in vitamin C levels compared to those on a moderate-carb diet.
However, it is important to note that most people do not get enough vitamin C, and levels are depleted even faster when the body is under stress. Therefore, while the ketogenic diet may lower vitamin C needs, supplementation or a diet rich in vitamin C may still be necessary to meet the recommended daily intake of 90 mg. Some keto-friendly sources of vitamin C include colorful bell peppers, kale, cauliflower, broccoli, Brussel sprouts, organ meats, and seafood.

Meat contains vitamin C, so it can be obtained on a zero-carb diet
Humans do not contain the enzyme required to produce vitamin C and must obtain it from their diet or supplements. While vitamin C is commonly associated with fruits and vegetables, it can also be found in meat, particularly organ meats. This is important to know for those on a ketogenic diet, which is high in fat, low in carbohydrates, and moderate in protein, as it can be challenging to get enough vitamin C from non-animal sources.
Vitamin C is a water-soluble vitamin, and the body cannot store it. Therefore, it is essential to consume it regularly to maintain adequate levels. Meat, specifically fresh meat, can be a good source of vitamin C. While muscle meat contains very little vitamin C, organ meats such as liver and kidney are rich sources. For example, a study found 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.
Consuming meat on a ketogenic diet can help individuals obtain sufficient vitamin C. In addition to fresh meat, organ meats can further boost vitamin C intake. It is worth noting that cooking methods can affect vitamin C levels in meat. Raw meat contains higher vitamin C levels than cooked meat, as common preparation methods like drying, roasting, and boiling can lead to significant vitamin C loss. However, putrefaction, a common preservation method among ancient foragers, increases vitamin C stability.
Overall, while a ketogenic diet may increase the risk of vitamin C deficiency, including meat in the diet can help individuals obtain sufficient vitamin C. The consumption of fresh meat and organ meats can ensure adequate vitamin C intake, even on a low-carb or zero-carb diet.
In summary, meat does contain vitamin C, and it can be obtained on a zero-carb diet. While supplementation may be necessary for some individuals on a ketogenic diet, including meat can help prevent vitamin C deficiency.

Some keto-friendly foods rich in vitamin C include kale, cauliflower, and peppers
Humans do not produce vitamin C naturally and must obtain it from their diet or supplements. The ketogenic diet, being low-carb, can make it challenging to obtain vitamin C from food sources alone. This is because many vitamin C-rich foods, such as citrus fruits, are also high in carbohydrates.
Other keto-friendly sources of vitamin C include broccoli, Brussels sprouts, strawberries, and lemons. While broccoli and Brussels sprouts are rich in vitamin C, boiling them can reduce their vitamin C content, so it is recommended to steam or roast them instead. Strawberries are a flavourful, keto-approved fruit that can be enjoyed fresh or frozen in smoothies and desserts. Lemons are another keto-friendly source of vitamin C, with one whole raw lemon providing 45 mg of vitamin C, or 50% of the DV.
While these keto-friendly foods provide good sources of vitamin C, it is important to note that supplementation may still be necessary to ensure adequate vitamin C intake on a ketogenic diet. This is because the diet's restrictive nature can lead to nutrient deficiencies, and research suggests that endurance athletes on a low-carb ketogenic diet experienced a significant drop in vitamin C levels.

Vitamin C deficiency is associated with health issues like scurvy and heart disease
Unlike other animals, such as cats and dogs, humans do not produce vitamin C naturally. Therefore, humans must obtain vitamin C from their diet or through supplementation. Vitamin C is found in plant foods like parsley, kale, cauliflower, broccoli, Brussel sprouts, and bell peppers, as well as liver and organ meats.
Vitamin C is a water-soluble vitamin, which means the body cannot store it. As a result, vitamin C must be consumed regularly. The recommended daily intake of vitamin C for men is 90 mg, while women are advised to consume 75 mg.
Vitamin C deficiency can lead to various health issues. One of the most well-known conditions associated with vitamin C deficiency is scurvy. Scurvy is characterized by symptoms such as tiredness, weakness, irritability, weight loss, muscle and joint aches, bleeding under the skin, swollen and bleeding gums, dry and brittle hair, and dry, rough, and scaly skin. While scurvy is rare in developed countries, it may occur in individuals with certain risk factors, such as alcohol use disorder and malnutrition.
In addition to scurvy, vitamin C deficiency has been linked to an increased risk of coronary heart disease and stroke. Research suggests that low levels of vitamin C may also impact bone health, increasing the risk of fractures, osteoporosis, and tooth loss. Vitamin C plays a crucial role in collagen production, which is essential for maintaining healthy skin, bones, and connective tissues. A deficiency in vitamin C can lead to impaired wound healing and increased susceptibility to infections. Additionally, there is evidence that vitamin C may influence fat metabolism and contribute to belly fat accumulation.
Following a ketogenic diet may increase the risk of vitamin C deficiency due to the exclusion of certain food groups. Therefore, individuals on a keto diet should ensure they are obtaining adequate amounts of vitamin C through vitamin C-rich foods or supplements to prevent potential health complications associated with vitamin C deficiency.
