A Beginner’s Guide to L-Carnitine

Today, we want to shed some light and insight onto a common compound that many either haven’t heard of or don’t know the uses and benefits of, or maybe just need a refresher! Further we’ll break down how it might be beneficial for your best furry friend! Afterall, we’re here to better serve your dog’s overall health and happiness, and we always like to hear from you about how we can do just that. So, let’s discuss L-Carnitine.


What is L-Carnitine?

Carnitine was first discovered to be a significant component of muscle. It is a specific type of compound—quaternary ammonium compound—and is involved in the system’s metabolism, which directly supports energy. Carnitine is concentrated in tissues of living beings like mammals, plants, and select bacteria. The tissues it is typically found within are skeletal and cardiac muscle.

Carnitine was first extracted from meat extracts in 1905 but has since evolved in its extrication from other sources, including plants. Carnitine occurs in two forms—D and L. Only L-Carnitines is already present in the body and is the form also found in food, therefore D-Carnitine has the possibility to be a harmful compound and contribute to potential health concerns due to it not already existing as a natural source in living beings. L-Carnitine is generally the utilized form, especially in supplements as it is already evident in many food sources.

The food sources L-Carnitine tends to be most prevalent in are red meat, fish, poultry, milk, whole wheats, and for vegetables it tends to be most predominant in asparagus. This is one of the factors in choosing raw dog food brands, or foods that are dense in meat ingredients, as a dog can obtain a source of L-Carnitine from their daily diet. However, the kidneys efficiently tend to conserve carnitine regardless of daily intake and while deficiency is not a typical concern unless genetic or medical, there are a few possible benefits to obtaining added carnitine, which we’ll talk about below.


L-Carnitine and Athletes

L-Carnitine may have benefits that boost the body's metabolism by improving mitochondrial function and increasing cellular energy. It can also provide enhanced recovery and prevent muscles from increased fatigue. These are a few of the reasons that L-Carnitine is popularly used by athletes as it could contribute to enhanced athletic performance. After strenuous exercise, and especially endurance exercise, L-Carnitine has possibilities to reduce muscle soreness and contribute to quicker recovery times in order to keep performance up without minor setbacks.


How Can Dogs Benefit From L-Carnitine?

L-Carnitine has the potential to play a key role in the health and wellbeing of our four-legged friends, especially as they respond similarly to humans where physical health factors are concerned. Dogs are athletes in their own right, and as L-Carnitine has already been discussed to have many athletic health benefits, these extend to dogs as well. As any of us dog owners know, sometimes dogs push themselves to the limits when they play since they don’t register many strenuous activities in the way that we do, but their bodies will still take impact when it comes to overexertion the way ours do. They still get sore, stiff, and fatigued, even if they keep pushing. So, a very active and energetic dog that gets lots of exercise could benefit from normal muscle recovery time, as well as maintain their cardiovascular health, by receiving further L-Carnitine supplementation.
