Then you may have bought fake L-carnitine. After a brand of L-carnitine treatment, I lost 22 pounds. To answer you with my example, I have lost weight for a long time. I learned a lot from exposure to diet pills. What I used to eat had great side effects. Say it when you are thin, and don't say it when you spend money. My body still can't stand it. Later, I watched L-carnitine recommended by Hunan Satellite TV, but I was afraid to try it because I was sensitive to diet pills. Finally, I saw a friend around me using L-carnitine, which also had an effect without side effects. I am a cautious person, I must know clearly before I buy something, so I found a lot of information about L-carnitine before I use it, and I also have a certain understanding of it. After using L-carnitine, it was found that the effect was good, and it dropped to the ideal weight (haha), and no side effects were found (I always wanted to drink water, probably because the metabolism was accelerated and water played an important role in the metabolic process).
