New study finds L-carnitine supplementation aids post-exercise muscle recovery.

Results presented by authors from Spain suggest that L-carnitine supplementation may serve as an ergogenic aid​, aiding in muscle recovery and damage, especially in cases of L-carnitine deficiency. It is demonstrated that l-carnitine alleviates muscle injury and reduces markers of cellular damage and free radical formation accompanied by attenuation of muscle soreness. L-Carnitine plays a role in free fatty acid metabolism and metabolic health and is required for the breakdown of fats and glucose into energy. Decreased levels of L-carnitine have been observed during pregnancy, supplementation has been shown to help improve plasma levels.

What is L-carnitine?

L-carnitine is sometimes identified as an amino acid; however, it is really a chemical derivative that is synthesized in the human body from the amino acids lysine and methionine. This synthesizing happens primarily in the brain, liver and kidneys. The body then uses the L-carnitine to release energy from lipids or fats.

L-carnitine is also acquired through food intake and supplementing. Meat, poultry, fish, and dairy products are the richest sources of L-carnitine; however, plant-based foods rich in lysine and methionine will allow the body to readily synthesize L-carnitine naturally.

Foods rich in lysine include legumes, avocado, nuts and grains. Foods rich in methionine include seaweed, spinach, sesame seeds, nuts, oats, white beans, chickpeas and corn.

Since it is present in virtually every cell in the body, and is essential for good health, L-carnitine is also approved for medical treatments.

WebMD states: “Taking L-carnitine by mouth or by IV is effective for treating L-carnitine deficiency caused by certain genetic diseases or other disorders. It’s approved by the FDA for this use.”

Study details

The new study focused on exercise-induced muscle damage. This damage encompasses both structural and functional aspects, leading to weakened strength, fatigue, muscle pain, and cramping.

The researchers noted their new study supports earlier findings that L-carnitine can serve as an “ergogenic aid” in helping offset this damage.

Exercise is known to induce oxidative stress which is characterized by an upsurge in free radical production. This is a side effect from mitochondrial activity and an increase in muscle inflammation.

Previous studies have provided evidence supporting the potential benefits of nutritional supplements, including L-carnitine, in the treatment of muscle damage. The research showed L-carnitine is not only essential for cellular energy metabolism in the muscles, but that it also acts as an antioxidant and reduces inflammation.

According to the researchers, supplementing with L-carnitine increases its levels in the blood, promoting improved blood flow and oxygen delivery to muscles. This reduces hypoxic damage and speeds recovery after exercise-induced stress.

The study was a review of 15 earlier studies, including both human and animal models.

Researchers reviewed dozens of earlier studies that examined the efficacy of L-carnitine supplementation in the treatment of post-exercise muscular damage. They isolated the studies that were randomized, double-blind controlled studies with a parallel design.

Three database were used to review and qualify the studies: SCOPUSMedline, and Web of Science.

Published results

Results from all the qualified studies suggested that L-carnitine supplementation did provide positive effects on exercise performance and recovery.

In their findings the researchers wrote that the supplementation was found to “improve lipid oxidation, preserve muscle glycogen, reduce inflammation, and potentially accelerate recovery from exercise-induced muscle injury.”

One study observed that L-carnitine supplementation is effective in attenuating the signs of tissue damage induced by exercise. Additionally, one dog-model study observed that the administration of L-carnitine increased muscle contractile force by 30% accompanied by an increase in blood flow.

The researchers hypothesized that L-carnitine exerts an effect on the vascular cells surrounding muscle, and thereby increases oxygen delivery.

Understanding Insufficient Responses in DNA Epigenetic Reports for Certain Supplements.

Introduction:

DNA epigenetic reports have gained popularity as a tool for personalized nutrition and supplementation recommendations. These reports provide insights into an individual’s genetic variations and epigenetic modifications, helping tailor dietary and supplementation choices. However, there are instances where individuals may experience insufficient responses to certain supplements, despite the recommendations provided in their DNA epigenetic reports. In this blog, we will explore some possible reasons behind these inadequate responses and shed light on the complexities of individualized supplementation.

  1. Variability in Absorption and Metabolism:

Even with personalized DNA epigenetic reports, individual responses to supplements can vary due to differences in absorption and metabolism. Factors such as gut health, digestive enzyme activity, and liver function play crucial roles in how our bodies process and utilize nutrients from supplements. Genetic variations and epigenetic modifications identified in the report may provide insights into potential areas of concern, but they do not account for all aspects of absorption and metabolism. As a result, individuals may experience insufficient responses to certain supplements due to individual variations in these physiological processes.

  1. Complex Nutrient Interactions:

Supplementation involves a delicate balance of nutrients, and interactions between different supplements or with other medications can influence their effectiveness. DNA epigenetic reports typically focus on individual genetic variations and provide recommendations based on specific nutrients. However, they may not consider the complexities of nutrient interactions within the body. Certain supplements may require co-factors or specific ratios with other nutrients for optimal absorption and utilization. Insufficient responses could arise if these interactions are not adequately addressed in the recommendations provided by the DNA epigenetic report.

  1. Environmental and Lifestyle Factors:

While DNA epigenetic reports offer valuable insights into genetic variations, they do not account for environmental and lifestyle factors that can influence the body’s response to supplements. Factors such as stress, sleep patterns, physical activity, and exposure to toxins can impact nutrient needs and utilization. Additionally, dietary habits and food choices can also affect the body’s ability to absorb and utilize supplements. Consequently, insufficient responses to supplements recommended in the DNA epigenetic report may be influenced by these external factors that are not captured in the genetic analysis.

  1. Individual Biochemical Individuality:

Each person possesses unique biochemical individuality, and while DNA epigenetic reports provide valuable information, they cannot capture the full complexity of an individual’s physiology. Personalized nutrition and supplementation are not solely determined by genetics; they also depend on other factors, such as epigenetic modifications, gene expression, and environmental influences. Therefore, some individuals may experience insufficient responses to certain supplements due to factors that are beyond the scope of the genetic analysis provided in the DNA epigenetic report.

Conclusion:

While DNA epigenetic reports offer valuable insights into an individual’s genetic variations and epigenetic modifications, they may not fully explain the reasons behind insufficient responses to certain supplements. Factors such as absorption and metabolism variability, complex nutrient interactions, environmental and lifestyle influences, and individual biochemical individuality all contribute to the complexities of individualized supplementation. It is essential to approach personalized nutrition and supplementation holistically, considering not only genetic information but also other relevant factors to optimize outcomes. Consulting with healthcare professionals who can interpret the DNA epigenetic report and provide tailored advice can help navigate the complexities and maximize the benefits of personalized supplementation.
