What Is L-Carnitine?
This amino acid derivative occurs naturally in the body, primarily in the liver and kidneys. It’s stored in tissues like muscles, heart, and brain, helping in fat metabolism and energy production. Though present in animal products such as meat and dairy, many people take it as a supplement to boost their health and fitness efforts.
The Science Behind L-Carnitine
Scientific research supports its effectiveness in enhancing athletic performance, weight loss, and cognitive function. Studies have shown that this nutrient can reduce muscle soreness, enhance recovery after exercise, and even support cardiovascular health. For older adults, it may help improve brain function by boosting energy and protecting against cognitive decline.
A 2018 study published in Frontiers in Nutrition highlighted its positive impact on exercise performance and recovery, while a 2021 review in the Journal of Clinical Medicine pointed out benefits for cognitive function and heart health.
