The body uses L Arginine supplements to dilate blood vessels. Read the following guide to know what to look for when finding the best L Arginine supplement.

Best L-arginine and L-citrulline Supplements

The body relies on many essential amino acids to produce nutrients it can’t do on its own. L-arginine, found in food sources such as pumpkin seeds and turkey, helps the body build proteins.

Supplements can benefit your workouts, cardiovascular health, and other circulatory problems. Consider the following characteristics when purchasing a supplement.

L-arginine Benefits

One of the most important characteristics of l-arginine is its ability to convert into nitric oxide once it enters the body.

Once it turns into nitric oxide, it helps expand the blood vessels and leads to improved blood flow.

Individuals with clogged arteries, angina, and other heart conditions can benefit from taking these supplements.

These supplements also help men experiencing circulatory issues that lead to low libido.

Finally, fitness-focused individuals can find these supplements helpful as it helps with oxygen delivery to the lungs and muscles.

Types of L-arginine

There are three main types of l-arginine available: free-form, with hydrogen chloride (HCL), and with alpha-ketoglutarate (AAKG).

Free-Form

  • Similar to the one found in food sources
  • Not attached to a protein or other compounds

HCL

  • Unlike free-form, this type attaches l-arginine to HCL
  • HCL has neutral pH, neutralizing the bitter taste of powders
  • HCL improves supplement absorption

AAKG

  • Combines AAKG acid with a salt of l-arginine
  • AAKG is naturally found in the body
  • Bodybuilders prefer this type of supplement for performance

Form

Supplements usually come in powder or capsule form, but powders are more convenient as they typically require only one dose daily.

The body metabolizes powder l-arginine better than capsules, leading to faster results.

Creams and injections are also available, but the latter has to be done under medical supervision.

L-arginine Dosage

Anything between 6- and 30-grams daily falls in the recommended range.

Keep in mind that most supplements measure their servings by milligrams (mg), and the recommended range is between 800 and 7,000 mg.

Since they are more concentrated, one serving of the powder can be one to three capsules, making powders more convenient.

Individuals with clogged arteries may need to take a higher dose (generally not more than 10 grams), but make sure the increase is gradual.

Added Ingredients

Plenty of the supplements on the market come with added ingredients, such as citrulline. Citrulline is often used to enhance the benefits of l-arginine.

For example, L-arginine Plus comes with l-citrulline, AstraGin, magnesium, and a variety of other vitamins and minerals to boost overall health.

Price

Usually, a one-month supply of supplements will cost between $6 and $50.

Any containers that cost more than $20 are usually formulated with AAKG, HCL, or stronger concentrations of l-arginine.
