This nutrient makes blood pressure drugs work even better
Last week, I showed you one of the most common causes of high blood pressure — a CoQ10 deficiency. But CoQ10 isn't the only nutrient deficiency that can lead to high blood pressure. There are several nutrient deficiencies that can lead to high blood pressure. But one of them is especially powerful if you're already taking blood pressure drugs.
This nutrient deficiency is that of the amino acid l-arginine. L-arginine helps in the formation of a substance called nitric oxide. Nitrous oxide is what causes the blood vessels in the body to dilate or widen. This is increases blood flow and decreases blood pressure.
Researchers recently gave l-arginine to a group of volunteers with high blood pressure. They found that the nutrient caused a significant dilatation of their blood vessels. And the dilatation brought their blood pressure down.

In another controlled study, researchers wanted to assess the effects of an arginine-enriched diet on blood pressure. They gave six healthy subjects either a placebo capsule or one containing l-arginine. Not surprisingly, those who received the l-arginine were the only ones to have a decrease in blood pressure.
So why would l-arginine be effective if you're already on blood pressure medication? Studies have shown that combining l-arginine with these drugs results in a much more effective treatment than just the drugs alone. So if you're on blood pressure drugs, talk to your doctor about taking l-arginine with it. Make sure you do this under the supervision of a doctor, as he may have to lower your medication dosage.
Many of you might have heard the rumor that taking l-arginine can result in cold sores. But I can assure you that this is an extremely uncommon occurrence. I have used a lot of l-arginine over the years in hundreds of patients and have never seen one case of it.
A good starting dose of this extremely safe amino acid is from 2,000-3,000 mg. Take this amount two to three times per day. Note that since l-arginine and the drug Viagra both increase nitrous oxide levels, you should not take this nutrient with Viagra unless under the guidance of a physician.
