Carnitine is a water-soluble amino acid derivative that the body naturally produces for energy. It is also found in animal proteins like chicken, fish, and beef. L-carnitine is a popular supplement in the keto community, as it is believed to help with fat burning and weight loss. The high fat content in the ketogenic diet means more fatty acids need to be transported into the mitochondria for oxidation, requiring more carnitine and increasing the risk of depletion of body carnitine stores. However, there are limited studies examining whether carnitine deficiency occurs on the ketogenic diet.

Carnitine is a water-soluble compound that helps transport fatty acids across the mitochondrial membrane for degradation into ketones
Carnitine is a water-soluble compound that plays a crucial role in the ketogenic diet. It is primarily responsible for transporting fatty acids across the mitochondrial membrane for degradation into ketones, a process known as ketogenesis. This transport mechanism is essential for the body's energy metabolism.
The ketogenic diet, or KD, is characterised by a high-fat, adequate-protein, and low-carbohydrate composition. This unique combination induces a state of ketosis, where the body relies on fat metabolism for energy instead of carbohydrates. As a result, fatty acids become the primary source of energy, and carnitine plays a pivotal role in their utilisation.
Carnitine, also known as L-carnitine, is a naturally occurring amino acid derivative. It is produced by the body and can also be obtained from dietary sources, particularly animal proteins such as chicken, fish, and beef. Red meats, in particular, are rich sources of L-carnitine. However, it is important to note that vegans and vegetarians may have lower carnitine intake from their diets, potentially leading to deficiencies over time.
The role of carnitine in the ketogenic diet is significant. As the diet involves a high intake of fats, more fatty acids need to be transported into the mitochondria for oxidation. This process relies on carnitine, and a deficiency can impair ketone body synthesis and energy levels. Some individuals starting a ketogenic diet may already have low carnitine levels, and the high-fat content can further decrease carnitine levels in the initial months of the diet.
Supplementation with L-carnitine is a popular choice among those following a ketogenic diet. It is considered a safe supplement, with potential benefits for muscle recovery and exercise performance. However, it is always advisable to consult with a healthcare professional before starting any new supplement, especially for those with health conditions or long-term supplementation plans.

Carnitine deficiency may impair ketone body synthesis and energy levels
Carnitine is a water-soluble amino acid derivative that the body naturally produces for energy. It is also present in animal proteins like chicken, fish, and beef. Red meats like beef have higher amounts of carnitine, and it is also found in smaller amounts in other foods like milk, dairy products, avocado, and beans.
On a ketogenic diet, carnitine is important because the high-fat intake means more fatty acids need to be transported into the mitochondria for oxidation, requiring more carnitine. This increases the risk of depletion of body carnitine stores. This risk may be magnified as food restrictions could reduce dietary carnitine intake. If carnitine is deficient, it will be difficult to achieve adequate ketosis on a ketogenic diet due to impaired ketone body synthesis, and energy levels may also be impaired.
Some studies have shown that carnitine levels decrease over the first few months of a ketogenic diet and, in some patients, dip into the deficiency range. However, levels then normalize after the first few months, with no evidence of a continued decline in levels. Other studies have shown that carnitine levels stabilize or increase slightly with long-term treatment.
Carnitine supplementation is a popular topic in the keto community, and some people choose to supplement with L-carnitine. L-carnitine is considered a safe supplement with a recommended daily dose of up to 2 mg. However, it is always best to talk to a doctor before making any diet or supplement changes, especially if you have a health condition or are planning on supplementing for a longer period of time.

Carnitine supplementation may be beneficial for gastric emptying and bowel function in patients with drug-resistant epilepsy
Carnitine is a water-soluble amino acid derivative that the body naturally produces for energy. It is also present in animal proteins like chicken, fish, and beef. Red meats like beef have higher amounts of carnitine, and it is also found in smaller amounts in other foods like milk, dairy products, avocado, and beans.
The ketogenic diet (KD) is a high-fat, low-carbohydrate, and adequate-protein diet that has been shown to be effective in treating drug-resistant epilepsy (DRE) in infants and children. However, the high-fat content in KD can lead to gastrointestinal disturbances, constipation, dyslipidemia, and micronutrient deficiencies. Carnitine deficiency has been reported in patients with epilepsy, particularly those being treated with valproic acid, carbamazepine, and phenobarbital.
L-carnitine supplementation has been studied for its potential benefits in improving gastric emptying and bowel function in patients with DRE on KD. One clinical trial recruited 30 patients aged 12 months to 18 years newly diagnosed with DRE who were starting KD. The participants were randomly assigned to two groups: one group received KD with L-carnitine supplementation, while the other group received KD only. The study found that L-carnitine supplementation had a significant positive impact on gastric motility and increased the frequency of defecation.
Another study by Berry Kravis et al. in 2001 looked at plasma total carnitine levels in 46 patients (aged 1-24 years) on the ketogenic diet. Out of the 38 patients monitored from diet initiation, three started on carnitine supplementation at baseline due to low levels, and five others needed supplementation later in the diet treatment. None of the patients showed any clinical signs of carnitine deficiency, and there was no worsening of seizure control with low carnitine levels.
Overall, L-carnitine is considered a safe supplement, and it is a popular choice in the keto community. However, it is always recommended to consult with a doctor or dietitian before starting any new supplement, especially for those with health concerns or those planning on supplementing for a longer period.

Carnitine levels may decrease during the initial months of a ketogenic diet but tend to normalize or increase with long-term treatment
Carnitine is a water-soluble amino acid derivative that the body naturally produces for energy. It is also found in animal proteins such as chicken, fish, and beef, with red meats like beef containing higher amounts. Carnitine is important on a ketogenic diet because the high-fat content means more fatty acids need to be transported into the mitochondria for oxidation, requiring more carnitine and increasing the risk of depletion of body carnitine stores. This risk may be higher for those with dietary restrictions that limit their intake of animal proteins, such as vegans and vegetarians.
The ketogenic diet (KD) is a high-fat, adequate-protein, and low-carbohydrate diet. It is a therapeutic option for epilepsy patients, as it provides ketones from the breakdown of free fatty acids for energy metabolism. Carnitine is the carrier molecule that transports these fatty acids across the mitochondrial membrane for degradation into ketones. Therefore, carnitine plays a crucial role in the ketogenic response.
Studies have shown that carnitine levels may decrease during the initial months of a ketogenic diet. For example, a study of 38 patients monitored from diet initiation found that the average total carnitine levels were lower after one and six months on the diet compared to baseline levels. However, these levels then increased again by 12 and 24 months, indicating a normalization or slight increase in carnitine levels with long-term treatment.
Another study by Coppola et al. in 2005 measured plasma free carnitine levels in 164 epilepsy patients on a ketogenic diet and found no abnormal levels of free carnitine. These results suggest that while carnitine levels may initially dip during the first few months of a ketogenic diet, they tend to stabilize or increase slightly with long-term treatment.
L-carnitine supplementation is a popular choice in the keto community, as it is believed to boost fat burning, weight loss, and energy levels. However, studies on its effectiveness are inconclusive. It is recommended to consult a doctor before starting any new supplement, especially for those with health conditions or concerns.

L-carnitine is a water-soluble amino acid derivative that the body naturally produces for energy. It is also present in animal proteins like chicken, fish, and beef. Red meats like beef have higher amounts of L-carnitine, and it’s also found in smaller amounts in other foods like milk, dairy products, avocado, and beans.
L-carnitine is a popular supplement in the keto community. This is because the high-fat content of a ketogenic diet means more fatty acids need to be transported into the mitochondria for oxidation, requiring more carnitine and, therefore, increasing the risk of depletion of body carnitine stores. Carnitine is the carrier molecule that transports fatty acids across the mitochondrial membrane for degradation into ketones. The integrity of this transport system is a prerequisite for an adequate ketogenic response.
However, the effectiveness of L-carnitine as a supplement varies. While some studies have shown that total carnitine does decrease over the first few months of ketogenic diet treatment and can even dip into the deficiency range, it then normalizes after the first few months, with no evidence of a continued decline in levels. Furthermore, in a 2005 study by Coppola et al., none of the 11 patients on a ketogenic diet developed abnormal levels of free carnitine.
In another study, three out of 38 patients monitored from diet initiation were started on carnitine supplementation at baseline due to low levels, and five others needed supplementation later in the diet treatment. However, none of them showed any clinical signs of carnitine deficiency, and did not show any worsening of seizure control with low carnitine levels.
It is important to note that adding supplements beyond those recommended by a dietitian could be harmful. Therefore, it is always best to talk to your doctor before making any diet or supplement changes.
