The mystery behind L-carnitine

It seems that L-carnitine is the rave these days if you want to stay fit and lose weight. Cold beverages and snacks left and right are incorporating the magical L-carnitine into their products to attract people looking for a dieting alternative. Is it truly magical?


I’ve been reading a lot into this L-carnitine thingy from the web before I start writing this post. I stayed away from articles posted by those trying to sell something to avoid any bias on my research.

What I found common in all that I read was pretty unremarkable. There’s no hard evidence to suggest that L-carnitine is really that effective in losing weight. Crap huh? But wait before you go, you might want to know these important details about L-carnitine first.

What does L-carnitine do?

L-carnitine is the nutrient that helps the body turn fat into energy. Mmm sounds good right? Usually, your body turn to carbohydrates for energy but L-carnitine will help it use fats instead.

Don’t bet too much on it though since L-carnitine is only one tiny cog in the body’s energy-conversion engine. And energy that is not used is converted back into fat so keep that in mind.

L-carnitine accelerates the speed of fat acids splitting and provides the protein synthesis which is necessary for muscular growth. In fact, serious sportsmen take this supplement to help prolong training sessions and reduce time needed for the body to rest.

So can you really lose weight from L-carnitine?

With only L-carnitine? Probably not. And just like any other legit weight-loss products, you should match your L-carnitine intake with proper diet and regular exercise. Again, there’s no hard evidence on the effectiveness of this in weight loss since most people don’t need that extra L-carnitine anyway.

Benefits of L-carnitine

Even without losing weight, there are some benefits in taking L-carnitine that I found out aside from supplying the added energy you need for your workout.

  • It is beneficial for people with cardio-vascular diseases
  • Prevents atherosclerosis
  • Cleans your body from wastes and toxins
  • Helps alleviate alcohol-induced liver damage

It is recommended that you take L-carnitine after breakfast or lunch if you feel fatigued or sluggish during the day. If you’re working out, feel free to take it before and/or after your training.

Side effects of L-carnitine

You would feel the effect of L-carnitine if you feel energetic throughout the day. Fortunately, it is very rare to experience side effect from taking too much L-carnitine. Do watch out for these side effects though:

  • Diarrhea
  • Nausea
  • Bad odor

There it is! L-carnitine sounds promising but again, it’s not clinically proven that it will help you lose weight but feel free to take those fruit juices with L-carnitine as much as you want.

In the end, just like it has been since the beginning of time, it’s the regular training and proper diet that will help you lose weight.
