The chocolate comes from a different supplier, but if you order two 17.5 oz. bars per month that will give you an ounce per day and it will still cost less than in a retail store, even including the charge for shipping.

Based on both research and actual experience, we recommend the following supplements, and we will give you a brief rationale for each.

CAUTION: be very careful when using prescription medications (Cialis, Levitra or Viagra) after optimizing your NO (Nitric Oxide) production following the recommendations on this website or in the book, Survival of the FIRMEST. You could have an exaggerated response with a very prolonged erection (called priapism) that can require a trip to the emergency room. We recommend that you carefully read and follow the precautions in the package insert and start with one-quarter of the lowest dose and gradually increase once you know you are not taking too much of the medication. You should expect to respond to lower doses of these prescription medications after optimizing NO production from your blood vessels.

Omega-3 fatty acids: These healthy essential fats increase NO production by your blood vessels and also help to prevent sudden death, heart attacks and strokes. We recommend 500 to 1200 mg. per day. They should be processed to remove environmental contaminants, and assayed to verify how much EPA and DHA they contain.

Folic acid: This B vitamin is a specific co-factor in the production of NO in the body. The recommended daily allowance (RDA) is 400 micrograms. We do not recommend taking more than the RDA, and if you are getting extra folic acid in wheat bread and cereal or if you eat a lot of veggies, we recommend cutting the tablets in two and taking only 200 micrograms per day. There has been some recent concern that excessive folic acid could increase colon cancer.

Vitamin C, 500 mg, and Vitamin E, 200 IU: These two antioxidants specifically act together to stimulate NO production. Vitamin C can worsen heartburn, so don’t take it before bedtime. We specify 200 IU of vitamin E because of studies suggesting that 400 IU may not be as good for overall health. CAUTION vitamin E supplements should not be used by people who are taking aspirin. Vitamin E adds to the anti-clotting effect of aspirin. Use the higher dose of pycnogenol instead of the vitamin E if you take aspirin.

L-citrulline: L-citrulline and L-arginine are the raw materials for NO production, but L-arginine is largely broken down before being absorbed by the body. L-citrulline is an important intracellular source of L-arginine, and what is inside the cell is what counts for NO production. There are no studies of treating erectile dysfunction with L-citrulline, but Dr. Ignarro has shown it to be effective in increasing NO in blood vessels in a rabbit model, and there is every reason to think that it would do the same in the human. We recommend powdered L-citrulline in the dose of 2 gm per day, but the optimum amount is not known. Natural sources are melons, particularly watermelon.

Pycnogenol: We recommend increasing intake of natural antioxidants such as blackberries, blueberries, chocolate, red wine, green tea and lots of fruits and vegetables. Also, pycnogenol is a potent antioxidant that helps decrease the breakdown of NO and has been shown to be quite effective for improving erectile function. We recommend 50-120 mg of pycnogenol per day.

Green tea or green tea extract: Green tea contains lots of antioxidants, may have a calming effect on the brain similar to meditation, and may reduce the risk of prostate cancer. We recommend the equivalent of 3 cups per day.

Chocolate: Chocolate has potent effects on NO production, but it usually contains a lot of sugar, which reduces NO. You can get all of the advantages and minimize the sugar with a reduced sugar chocolate. Matitol does raise blood sugar but it is broken down to glucose, which has less adverse effect than sucrose, the usual sugar added to chocolate. You will get to enjoy it as much as regular chocolate, but don’t overdo it. This is our only recommendation that could make you gain weight. An ounce or so will give you lots of antioxidant and is enough to look forward to each day. Have some for a mid-afternoon break along with a cup of green tea. These supplements are all quite reasonable in price. They will cost you a lot less than Viagra, Cialis or Levitra, and if you do require some extra help, you will need a lower dose of these medications. We have done the work for you to find the recommended doses and best available prices, which are comparable to or less than what you would pay in the usual retail store. Rather than just treating the symptom (erectile dysfunction), you will be improving your erectile function and improving your vascular health! You will know exactly how well you’re doing. You have the ultimate indicator right there between your legs!
