L-Carnitine Base
L-Carnitine Base is a naturally occurring amino acid derivative that is important for heart and brain function, muscle movement, and many other body processes. It is used to increase L-carnitine levels in people whose natural level of L-carnitine is too low. Some people also use L-carnitine for conditions of the heart and blood vessels, serious kidney disease, and many other conditions, but there is no good scientific evidence to support these uses.
Some studies suggest that L-carnitine may offer some health benefits, including increased weight loss, improved brain function, and more. L-carnitine supplements at doses of 0.25 to 4 g/day for 2 to 52 weeks reduced fasting blood glucose, insulin resistance, and glycosylated hemoglobin levels in a meta-analysis of randomized controlled trials.
Another study observed a reduction in heart failure and deaths among participants who took L-carnitine supplements. Animal and human studies have shown that supplementation with L-carnitine improved protein synthesis, prevented cell death, decreased protein breakdown, and more.
The recommended dosage is roughly 1–3 grams per day. Most people tolerate L-carnitine well. However, some people may experience mild side effects when increasing their L-carnitine intake, especially with long-term use. These side effects may include nausea, vomiting, stomach upset, diarrhea, and fishy body odor. It is important to talk to a healthcare provider before taking L-carnitine supplements to discuss any medications being taken and the possible drug interactions.
