If you want to improve your heart health, you may take l-arginine and l-citrulline supplements – but is l-arginine or l-citrulline better?

Many people use l-arginine and l-citrulline supplements for their health for various reasons. For example, some take them to decrease their blood pressure while others take them to boost their workouts.

However, before taking these supplements, it’s a good idea to figure out which one is better than the other. The following is an overview of what these supplements do and if one is better (or not).

What is L-arginine?

is l-arginine or l-citrulline betterL-arginine, or arginine, is an amino acid that comes from dietary proteins. As a semi-essential amino acid, you can generally get it from diet alone except in some cases like medical conditions or age.

In the case of the latter, a doctor can recommend l-arginine supplements to make up the deficiency. In addition, these supplements are used in clinical settings to treat certain critical illnesses.

L-arginine has two main functions: building protein and improving circulation. Therefore, people who have high blood pressure take l-arginine supplements to increase their blood flow.

What is L-citrulline?

On the other hand, l-citrulline is a nonessential amino acid because the body produces it on its own. However, by taking supplements or eating certain foods, you can increase your citrulline levels and experience certain benefits.

While it doesn’t build protein like l-arginine, it can provide health and exercise benefits. Moreover, l-citrulline plays a key role in the urea cycle as it helps rid the body of harmful compounds like ammonia.

It can also help relax and widen blood vessels while helping with muscle building.

How Do They Work?

L-citrulline increases vasodilation, widening arteries and veins to improve circulation and lower blood pressure. The amino acid is also a precursor to l-arginine; in other words, after consuming l-citrulline, the body converts some of it to l-arginine.

While they may have some individual strengths, l-arginine and l-citrulline are more or less two parts of the same whole. Furthermore, by taking l-citrulline supplements alongside l-arginine supplements, you can increase arginine in the body even more.

Once the body converts l-citrulline to l-arginine, the amino acids are converted to nitric oxide. As a result, nitric oxide relaxes blood vessels through vasodilation and improves circulation.

By increasing blood flow, these supplements help improve blood pressure as well as exercise performance. While citrulline doesn’t build protein, it can stimulate an important signaling pathway in muscle building.

The Outlook

If you want to improve muscle building, l-citrulline is better, while l-arginine is best for circulation problems. However, while they each have their particular strengths, it turns out they work better together.

Instead of choosing one over the other, why not take a supplement that contains both amino acids and more? HeartBeet Complete contains these two amino acids, as well as beetroot powder, turmeric, CoQ10, and key vitamins and minerals.

Together, these ingredients work to improve circulation, workout performance, cholesterol levels, and overall health. Don’t get stuck with just one of these supplements: try HeartBeet Complete and maximize your benefits.
