At my anti-aging clinic, I have been encouraging my Alzheimer's patients to take arginine for many years. And I've seen firsthand how it prevents their cognitive decline, keeping their minds sharp and their memories clear.
Make sure you buy either arginine or L-arginine. To your body, there's no significant difference between these molecular cousins. But avoid D-arginine, which has more value in lab experiments than in your body.
You should also supplement with either citrulline or L-citrulline, two other biochemical relatives of arginine. The interaction of the amino acids further increases the production of nitric oxide.
You can get capsules of these nutrients online or from health food stores. I recommend daily doses of 6,000 mg. of arginine (or L-arginine) and 1,000 mg. of citrulline (or L-citrulline).
