Product Overview

  • Supports Peak Performance
  • Amino Acid Supplement

L-Arginine and L-Citrulline are two amino acids bundled into a single powerful supplement. L-Arginine is an important factor in muscle metabolism and a precursor for nitric oxide, which promotes increased circulation by relaxing blood vessels. L-Citrulline helps the body rid itself of ammonia, a by-product of exercise. This clearing enables the body to recover after a workout.

Suggested Use

1 tablet four times daily.

Other Ingredients

Stearic acid, maltodextrin, silicified microcrystalline cellulose, modified cellulose gum, and colloidal silicon dioxide.

Works for erectile dysfunction!

Posted by Reviewer3118989 on Feb 21, 2008

My hubby takes 3 tablets 20 min. before we get together. With his complications of diabetis this really does the trick. The facial flushing is bearable. The Dr. says to drink a lot of fluids when using this product. Superior product formulation. Works well for erectile dysfunction. Ultimately we need to bring his cholesterol back to normals levels using other products. This works wonderfully well in the mean time until the erectile dysfunction is no longer an issue.

Since taking the Arginine - Citrulline caps, my blood pressures has stabilized at 110 to 120 on systolic and 65 to 75 on the diastolic. This on a person who for most of his life (more than 60 years) has been around 140/110. Other effects are more subtle and cannot be quantified.

Helps with my blood pressure.

The product keeps your arteries open which helps to lower blood pressure and reduce heart attack risk.

Amazing Results

Posted by Reviewer1014741 on Jun 09, 2010

I know, the title sounds like and "as seen on tv" ad. But I am very pleased with L-Arginine L-Citrulline Complex from Source Naturals. I have been taking two medications for high blood pressure. My BP had been within the acceptable limits on those medications, but not what I would call great. Having read some of the research done on the relationship between L-Arginine and BP, I decided to give this combination a try. My BP improved significantly. I am now down to one medication and will be looking to see if I can wean myself off that one as well. Great product! These are my results and I can only speak to my experience.
