L-Arginine and Blood Pressure: Dosage & Scientific Evidence

The amino acid L-arginine creates the excretion called urea, which removes ammonia from the body. The body typically makes enough L-arginine but supplements can help those suffering deficiencies due to poor nutrition or certain medical conditions.

L-Arginine and High Blood Pressure

• Scientific research has not conclusively proven the affects of L-arginine on high blood pressure. But, in theory, the supplement should lower blood pressure levels because arginine converts into nitric acid, which relaxes blood vessels.

Sources of L-Arginine

• Food sources of arginine include walnuts, raisins, brown rice, sunflower seeds, and chocolate.

  L-arginine is also available in supplement form.

Dosage

• A typical dose requires 2 to 3 milligrams taken three times a day. Research studies have included dosages of up to 16 milligrams per day extended over a six month period.

Side Effects

• Common side effects include nausea, cramps, and increased blood sugar. Blood chemicals and electrolytes may be changed by taking L-arginine.

Warning

• Patients with liver, kidney, or bleeding conditions should avoid the usage of this supplement except under strict supervision by a doctor.
