From the American Heart Association to the National Academy of Sciences, there is ample proof that L-arginine does lower cholesterol levels. These studies have shown the amazing benefit of L-arginine to lower ‘low density lipoprotein’ levels, or ‘bad cholesterol,’ while positively influencing ‘high density lipoprotein’ levels, or ‘good cholesterol.’

The L-Arginine Cholesterol Studies

American Heart Association Journals

In a study conducted by the Insititute of Clinical Pharmacology and Department of Cardiology and Pathology in Hannover, Germany, researchers found that “L-arginine improves NO-dependent vasodilator function in cholesterol-fed rabbits and completely blocks the progression of plaques via restoration of NO synthase substrate availability and reduction of vascular oxidative stress.”l-arginine for cholesterol

What does that mean? Basically, this Germany study proved to everyone that l-arginine does in fact stop plaque build-up on the arteries and restores the body’s ability to produce Nitric Oxide (NO), which facilitates healthy circulation and lower blood pressure. When plaque, in the form of cholesterol, builds up on the arteries this plaque blocks the endothelial cells from producing NO. When those cells, which line the artery walls, cannot produce NO the body loses its ability to control blood circulation. When that happens, cholesterol, or plaque build-up, blocks the arteries completely leading to many heart diseases.

L-arginine lowers cholesterol levels by restoring the body’s ability to produce Nitric Oxide. See the full report here.

The National Academy of Sciences

A study conducted by the Department of Geriatrics at Nagoya University Graduate School of Medicine in Japan proved the importance of L-citrulline and L-arginine in combination to fight bad cholesterol. “Treatment with L-arginine plus L-citrulline antioxidants showed a significant increase in NO…the combination of L-arginine and L-citrulline possesses the capacity to elevate NO.” The study goes on to say that the “systemic administration of L-arginine has been demonstrated to slow the progression of the disease (atherosclerosis).”

Plainly speaking, L-arginine does lower cholesterol levels by increasing Nitric Oxide and reducing plaque build-up. Combined with L-citrulline, it has an added affect.

Journal of Nutritional Biochemistry

In 1999, a study was published adding to the ample proof that l-arginine lowers cholesterol levels. Researchers found that L-arginine was affective in lowering cholesterol levels in rats when added to their diet.
