What Is Arginine?

What is arginine?

What is arginine? Arginine is a semi-essential amino acid that your body relies on for many functions, like supporting a healthy immune system, powering up workouts, and even promoting radiant skin and hair!

How does arginine work in your body?

How does arginine work its magic within your body? Arginine works as a precursor to nitric oxide (NO).

Nitric oxide helps your blood vessels relax and expand, allowing for better blood flow. Blood contains important nutrients and oxygen, both of which aid the body in cell turnover, healing, and function.

Healing goes where blood flows, so it’s easy to see why arginine is so important to your health. To illustrate this, let's take a real-life example.

Picture your morning workout session, where you're pushing yourself to break your personal record on the treadmill. As you run, your muscles are demanding more oxygen, and arginine helps deliver it by producing nitric oxide. This increased blood flow not only benefits your muscles but also supports overall cardiovascular health.

Are there different types of arginine? What's the best?

There are three main forms of arginine supplements L-arginine, L-arginine hydrochloride (HCL), and L-arginine alpha-ketoglutarate (AKG). First up, L-arginine is the most common form and is the one your body naturally produces.

It's also the type you'll find in most arginine-rich foods. However, L-arginine supplements may sometimes cause an upset stomach, which is where L-arginine HCL comes in.

The HCL form is created by combining L-arginine with hydrochloric acid, making it easier to digest; however, the pH is more acidic than pure L-arginine itself. This form may be helpful for those with gastrointestinal issues.

Last but not least, we have L-arginine AKG. This form combines L-arginine with alpha-ketoglutarate, a compound involved in energy production in your cells.

This dynamic duo is particularly popular among athletes and fitness enthusiasts, as it's believed to help enhance endurance, muscle strength, and recovery. So, which one is the best?

Are you just starting with arginine supplementation or are you looking to amp up your fitness game? Do you have a sensitive stomach or can you digest supplements with good tolerance? Here is a quick review of the different types of arginine:

• L-arginine: great for beginners and those who can tolerate supplements well
• L-arginine hydrochloride (HCL): if you have digestion issues, you may want to try this form
• L-arginine alpha-ketoglutarate (AKG): best for athletes and those looking to improve fitness

Whichever form you choose, you'll enjoy the great benefits this amino acid has to offer.

What are the benefits of arginine?

Here are some of the health benefits of arginine.

1. Supports blood flow: Arginine boosts nitric oxide production, which helps relax and widen blood vessels, ensuring your muscles get all the oxygen and nutrients they need during a workout. A study published in The International Journal of Angiology found that because arginine helps produce nitric oxide, it may even act as a natural anti-hypertensive agent, naturally lowering high blood pressure!
2. Supports endurance: Going the extra mile (literally) has never been easier! Arginine may help delay the onset of fatigue during exercise, allowing you to push harder and longer. Picture yourself channeling your inner Energizer Bunny as you power through that final set or sprint.
3. Supports faster recovery: Nobody likes the dreaded post-workout soreness (DOMS, anyone?). Luckily, arginine has your back! By supporting blood flow, it aids in muscle recovery. L-arginine is a great go-to option for anyone looking to increase their physical activity while decreasing their recovery time, so you can bounce back and hit the gym again in no time.
4. Supports muscle growth: Arginine may help stimulate the release of growth hormone, which plays a key role in building and maintaining lean muscle mass.
5. Supports immune health: Arginine is important in the formation, differentiation, and maturation of important immune cells that protect us from infection and illness. Taking arginine may help support the immune system and potentially avoid things like colds and flu.
6. Supports blood sugar regulation: Research has shown that arginine may support glucose metabolism, benefiting those with Type 2 Diabetes and helping the body use blood sugar more efficiently.
