The metabolic process of fat goes through an obstacle, that is, mitochondrial membrane. Mitochondria can burn fat to release energy, which is consumed by the body, but long-chain fatty acids can't pass this barrier. L-carnitine plays the role of porter! Take the long-chain fatty acids out of the protective cover bit by bit and send them to mitochondria for further oxidation!

L-carnitine is just a carrier, and how much fat is consumed does not depend on L-carnitine. It's like that all the bricks needed in Gai Lou are transported by car, but how many bricks Gai Lou consumes does not depend on the number of cars, but on the size and structure of the building.

Simply put, if the amount of exercise (energy consumption) is not large and the fat consumption is not much, just increasing L-carnitine will not increase the oxidation function of fat, so it will not help to lose weight.

Under normal circumstances (the amount of exercise is not very large), the human body will synthesize enough L-carnitine by itself, and there will be no shortage of L-carnitine.

Only when the amount of exercise is large, such as athletes or bodybuilders, the energy consumption per unit time is large, and the "flow" of fat oxidation energy supply is large, it is possible (supported by many research reports, but denied by some research reports) that the synthesis of L-carnitine is "relatively insufficient". At this time, taking more L-carnitine, expanding the scale of the transport fleet (carrier) and transporting more bricks (fatty acids) to the construction site (mitochondria) per unit time are obviously beneficial to the oxidation and consumption of more fat.
