"When your endothelium is young and healthy, you enjoy a steady current of nutrient- and oxygen-rich blood circulating to every nook and cranny of your body. And you enjoy all the wonderful benefits of increased nitric oxide!
But when it's older and not as healthy, your nitric oxide levels start to plummet. If you don't get enough vigorous exercise, it makes them drop even more."
The following is a summary of the "Six Essential Ingradients You Need" to stimulate nitric oxide production, my recommendations for a couple of brands, and an added bonus nutrient.

Magnesium: I prefer (and HIGHLY recommend) Magnesium Threonate. Unlike other forms of the element, it crosses the blood-brain barrier which targets neurons directly. Since it is a mineral, take on an empty stomach (one hour before a meal or 3 hours minimum afterwards).
a. Vitamin C: This is one of my basic nutrients. I take two forms of it. The first is good old Ascorbic Acid, which is cheap and ubiquitous. You will have to split the daily dose since it is water soluble. Take with meals.
b. The second form is Ascorbyl Palmitate, a fat soluble Vitamin C, which provides antioxidant protection to your heart and lungs, and several other target organs. You only need to take it once daily, preferably with a fatty meal (for better adsorption). Make certain they are good fats, such as olive and coconut oils, Omega-3 fatty acids, and animal fats (in limited amounts).
Hawthorne Berry: "(T)o increase blood flow, support healthy circulation, and help you get even more benefits from l-citrulline and beet root powder."
Vitamin B12 (cobalamin, cyanocobalamin): The form I use is a combination of Methyl Vitamin B12 and Methyl Folate by Jarrow Labs. This formulation is not only better absorbed than others, but the two nutrients work synergistically.
Beet Root Powder: This is an excellent nitric oxide stimulator ("NOS"). I use it when I can afford it, and it's arterial dilation properties are readily apparent. Not quite as strong and long-lasting as Viagra, but it's a decent natural, and cheaper, adjuvant.
L-citrulline: I have not tried this amino acid to stimulate NO, so I can only defer to the article regarding its effectiveness. I did use its precursor, Arginine, in my bodybuilding days for two reasons. The first was at bedtime as a growth hormone-releaser. The second was pre-workout as an NOS. Because NO dilates arteries and arterioles, it helps weightlifters achieve a greater "pump." Always a good thing.
