Rating: 4 out of 5
Pros

Beyond Raw L-carnitine reviews favorably when compared with other products. It is gluten free and highly rated—not only by consumers, but by resellers like GNC, as well. Because it is the raw powder, the price is much lower than other highly-rated sources.

Cons

There is no mention of GMP certification or FDA registration. Also, there is no mention of where their product is sourced.

Bottom Line

Beyond Raw L-carnitine benefits the consumer as a low-cost source of carnitine. If you trust companies like GNC, you can trust Beyond Raw, but their lack of disclosure raises questions in my mind.

What is L-Carnitine?

L-carnitine is a popular and safe supplement that can increase your energy level and help you burn more fat. It does not provide essential nutrition, so there is no recommended daily value at this time. Because it is common in the diets of most people, L-carnitine side effects are uncommon and generally mild.

What Does L-Carnitine Do?

The L-carnitine molecule transports fat into the mitochondria of the cells. It is then available to be burned. It also removes waste products from the mitochondria.

The Biggest Benefit of L-Carnitine is… – Dr. Eric Berg DC

Is L-Carnitine Effective For Weight Loss?

L-carnitine is primarily marketed together with other diet aids and is clinically proven to burn fat. It is most effective as part of an overall system of diet, exercise, and supplementation.

Is L-Carnitine Injection Effective?

L-carnitine can be delivered orally or intravenously, and it is effective both ways. Most consumers receive their L-carnitine orally, but your doctor can tell you which method is right for you.

What Is The Best L-Carnitine Supplement?

There are many L-carnitine benefits that you can reap from five different formulations, each with its own benefits. There is often confusion about what each formulation does, and the labels are not always altogether informative. Sometimes it’s even hard to know what type you are buying, so it’s important to educate yourself and pay attention to detail. The highest-rated brands have the clearest and most informative labels, so going with a brand name you know and trust is a good idea.

  • L-carnitine tartrate is formulated to absorb quickly. It is popular with athletes. Many companies do not include tartrate in the name of their product, so it is important to read the ingredients on the back.  
  • L-carnitine fumarate is a patented formulation that is primarily directed at heart patients. Like the tartrate formulation, sometimes you will only know you are buying the fumarate version if you read the ingredients label.  
  • Acetyl-L-carnitine is the form of L-carnitine that can reach the brain and the central nervous system. The acetyl group helps carnitine cross the blood-brain barrier and has other functions of its own.   
  • Propionyl-L-carnitine is a formulation that increases blood flow and, in addition, provides other synergistic effects on the nervous system.

Carnitine works best when you combine it with other supplements like Nowfoods selenium and other fat burning supplements. Combined with diet and exercise, they can help you burn more calories and meet your weight loss goals.

Try Healthy Snacks Between Meals

One of my favorite fat loss tips is to use healthy snacks in between meals to keep your calorie count down. I like Animal Pak Animal Cuts because it is a low-fat, low-sugar option packed with protein. Eating protein before a workout will improve your muscle-building results when exercising.

If you are considering the keto diet, Bulletproof Brain Octane MCT Oil is an effective product. It helps you get your calories in a form that your body can burn quickly and easily. If you combine it with L-carnitine and other metabolic boosters, get ready for a huge surge in energy and performance.
