Benefits of Combining Supplements: L-Carnitine & Methyl B-12

What is L-Carnitine?

L-Carnitine is found in almost all of the body’s cells and plays a vital role in energy production.  It transports fatty acids into a cell’s mitochondria-where fats are burned to create usable energy.  When taken as a supplement, L-Carnitine has been shown to have a beneficial impact on weight loss and improved brain function. It has also been linked to improved heart health, exercise performance and recovery, reduction in muscle soreness and increased oxygen supply to muscles.  For those who suffer from type 2 diabetes, L-Carnitine may improve the body’s ability to utilize carbs for energy. 


What is Methyl B-12?

Vitamin B-12 is an essential vitamin that the body needs but is unable to produce. There are many roles of vitamin B-12 in the body including supporting normal function of the nerve cells, the formation of red blood cells, DNA synthesis, boosting energy, helping prevent heart disease and improving memory.  A B-12 deficiency can cause anemia-specifically red blood cells that are larger and irregularly shaped.  These red blood cells cannot transport oxygen throughout the body causing fatigue and weakness.  Additionally, vitamin B-12 has been shown to improve mood and reduce symptoms of depression. 


Why do they work well when taken together?

There have been links made between vitamin B-12 deficiency and an increase in the loss of natural levels of carnitine.  Multiple things can result in a B-12 deficiency.  Vegan and vegetarian diets can result in this deficiency.  Medical procedures such as gastric bypass or gastric sleeve can inhibit the body’s ability to sufficiently absorb B-12.  Genetic factors such as the mutation in the MTHFR gene negatively impacts the body’s ability to utilize vitamin B-12.  To combat any of these deficiencies, supplementing L-Carnitine and Methyl B-12 together can improve energy utilization and enable the body to burn fat more efficiently.
