CARNITINE Supplements Fully Explained

What is Carnitine?

Carnitine is everywhere. No, I don't mean on Campus Protein, I mean Carnitine is found in nearly all of the bodies cells. Carnitine is one of those special ingredients found in supplements because the science behind it almost sounds too good to be true. This ingredient is a naturally occurring (meaning your body produces it) amino acid that plays a vital role in energy. May I stress again, a vital role...hence the reason why people love this ingredient but we will talk about that later. Finally, there are two forms of Carnitine; D-Carnitine and L-Carnitine, however, the L-Carnitine is the only one active in the body and the one we care about. 


Where does Carnitine come from?

Like we said earlier, this is a natural ingredient and found in everyday foods we eat. Our bodies consume them and we convert it to energy for our cells. Carnitine can be found in animal products such as meat, fish, poultry, and milk. The redder the meat, the more carnitine is in it.

How does Carnitine work?

Now that is one of the most important questions being that the answer is why people take it...and LOVE it. Here comes the science answer...Carnitine transports long-chain fatty acids into the cell so they can be oxidized (or used) to produce energy. 


You know when you are saying you need to burn carbs or burn fat for energy...that is the carnitine in your body (or cells) burning that energy (or fat). 


Are you confused? I got you - Carnitine aids in burning fat for energy. Pretty easy now to understand right?


Main Reason to take Carnitine

Weight Loss: Due to its incredible properties and how it works, Carnitine allows the body to burn more fat for energy making you burn more calories and will aid in fat loss.
Muscle Repair: Carnitine is found in 98% of muscles and when the body has an ample source of Carnitine, it allows the body to prevent muscle breakdown and aids in recovery.

Other Reasons?

Reduce Aging: In a double-blind experiment, Carnitine showed the slowing down of cell aging. In normal terms, our cells stayed young and so did the subjects in the experiment. 
Cardiovascular and peripheral arterial disease: Increases blood flow and has been proven to decrease mortality in bodies with cardiovascular issues.
Cancer Patients: Carnitine showed that it aided people battling cancer through chemotherapy with increased energy. People who are in Chemo have low carnitine levels due to the treatment and supplementing with Carnitine showed to give people more energy than those who did not. 

What are the side effects of Carnitine?

There are very few concerning side effects to supplementing with Carnitine. Most of it has to do with your tummy not being able to handle it. This usually happens at close to 4g or 4000mg of Carnitine per day. You may experience nausea or diarrhea if that is the case. 


Who should take carnitine?

It really seems that taking carnitine for increased “natural” energy and weight loss seems like a win-win. Sip or take it in a shot and you will be giving the body the nutrients it needs to help burn more fat for energy. The more energy you use, the leaner you get. 


Also being that Carnitine comes from meat sources, if you are a Vegan this holds even more benefits. 


If you are any of the “other” reasons above, it seems like it is worth a shot but we always recommend consulting with your doctor before doing anything like that. 


What are the different types of Carnitine and how are they different?

All forms of Carnitine minus D show an increase in cellular energy however, different forms of Carnitine have been proven to also aid in other areas. Here are the different forms:

Acetyl L-Carnitine: Often called ALCAR, this is the most effective form of Carnitine for the brain that will help regenerate the cells in the neuro tissue.
L-Carnitine: This is the form of carnitine used for its findings in the circulatory studies and helps with blood flow. 
L-Carnitine Tartrate: This is the fastest absorbing form of Carnitine which has been proven to aid in muscle recovery. 
D-Carnitine: This is an inactive form of carnitine that should not be consumed by the body due to its effects inhibiting absorption


When is the best time to take Carnitine?

There are three ideal times to take Carnitine: The morning right when you wake up, right before a workout and then right before you go to bed. Being that this is just “natural” energy, Carnitine is and should always be Stimulant Free. It is also ideal to take it 2x a day at around 1500mg per serving.
