Like many other amino acids, L-Carnitine is a great regulator of both moods and emotions

How can I lean on L-Carnitine?

Various studies have been conducted on L-Carnitine’s efficacy in improving mood and antidepressant properties. A study conducted on mice and long term use of L-Carnitine supplementation found that L-Carnitine was able to alter brain energy metabolism (the process of generating energy from nutrients) and increase the content of noradrenaline and serotonin, which are the hormones responsible for calm and happy moods (Smeland et al., 2012). L-Carnitine has shown to improve symptoms of depression by increasing the neurotransmitter dopamine to enhance energy, focus and motivation (Clinical Applications of Scientific Innovation, 2017). L-carnitine is able to achieve these effects because it has a  similar structure to acetylcholine (a compound in the brain that produces neuromodulators and Emotional Feelings of calmness), so it can also  stimulate acetylcholine receptors in the brain to release dopamine (Durand-de Cuttoli, et al., 2018)

Can I get L-carnitine from food?

You can get your daily dose of L-carnitine from a variety of food sources with the highest amounts being in red meats. Lesser amounts can be found in dairy, chicken, fish, beans and avocado (Oregon State University, 2019). For people who don’t consume red meat, getting higher amounts of L-carnitine through your food intake can be challenging. Data shows that adults who eat mixed diets including red meat and animal products consume around 60-180mg of carnitine daily compared to adults eating a vegan diet who consume around 1012mg of carnitine daily (National Institutes of Health, 2021). With such a significant difference between dietary carnitine intake Lean Boost is a great supplement alternative to help boost your L-carnitine levels for the most therapeutic effects.
