Speaking of L-carnitine, I believe many people are still unfamiliar with it, so here is a detailed explanation of what L-carnitine is. Strictly speaking, L-carnitine is a kind of ubiquitous "substance". Just like the carotene in carrots and the apple elements in apples, L-carnitine is also contained in our daily diet, such as in meat products. L-carnitine is an amino acid that helps convert fat into energy. However, the L-carnitine sold in many stores on Taobao Mall is a processed health weight-loss product, so they are different concepts.
