"This is the first study to look at the association between flavonoids and erectile dysfunction, which affects up to half of all middle-aged and older men," said lead researcher, Professor Aedin Cassidy. "Men who regularly consumed foods high in these flavonoids were less likely to suffer erectile dysfunction. In terms of quantities, we're talking just a few portions a week."
Erectile dysfunction (ED) is defined as the persistent inability to attain and maintain an erection that is sufficient to permit satisfactory sexual performance (1). The current pharmaco-therapeutic research in ED focuses on underlying endothelial dysfunction as the root cause for ED and introduction of phosphodiesterase type 5 inhibitors to potentiate nitric oxide (NO) action and cavernosal smooth muscle vasodilation, has revolutionized modern ED treatment over the past two decades (2). In contrast to Western Medicine, the traditional and complementary medicine (TCM) aims at restoration and better overall bodily regulation with medicine to invigorate qi (energy) in vital organs such as kidney, spleen and liver; to enhance physical fitness, increase sexual drive, stabilize the mind and improve the overall situation resulting in natural and harmonious sexual life (3).
These medications don’t work for everyone but they are easy to use and work for around 60% of people who try them. They work by making it easier to get an erection by reducing the effect of (inhibiting) the chemical PDE-5. This chemical is used in the body to make sure there isn’t too much blood in the penis during an erection, but if you have erectile dysfunction then this chemical ends up over-compensating.
When considering vitamin supplementation for erectile dysfunction, one of the first vitamins that you may come across in literature would be Vitamin D. This is a vitamin that can be easily obtained through many types of dairy products like milk, cheese, and yogurt and is also in abundance if you live in a tropical climate. Sunlight is able to give us a natural dose of vitamin D daily.  Although vitamin D is usually associated with improving bone strength and prevention osteoporosis, another valuable feat of vitamin D is the fact that it helps reduce atherosclerosis. Studies confirm that there is a similar underlying mechanism that occurs between conditions like cardiovascular disease and erectile dysfunction. As blood vessels are damaged and filled with plaques, the diameter for blood to flow through is gradually reduced. After a few years, the amount of blood may be reduced substantially. Vitamin D is able to help activate cells that remove some of these dangerous plaques and delay the onset of ED. 
These underrated kernels are rich in zinc, and people with higher levels in their system have been shown to have a stronger drive than those with lower levels. They’re also a good source of magnesium, which boosts testosterone and keeps sperm healthy and viable. Pine nuts are the primary ingredient in pesto, so go Italian on your next date night, or sprinkle them on a salad with avocado, tomatoes and salmon.
Derived from the bark of a West African evergreen tree, yohimbe was the go-to ‘script for a wonky willy prior to the advent of wonder drugs like Viagra, Walker says. “Yohimbe enhances sexual performance both by blocking certain neurotransmitters in the brain and by increasing the release of nitric oxide in the cavernosal nerves of the penis,” he explains. And it pairs well with other erection-friendly tablets: A 2010 study in the Iranian Journal of Psychiatry found that a combination of yohimbe and L-arginine successfully helps guys get it up. However, yohimbe also has a handful of side effects, including elevated blood pressure and anxiety, so definitely talk to your doctor before you start on the supp.
Another age-old therapy for ED is acupuncture. This is an ancient Chinese treatment where thin needles are inserted into specific points of the body to relieve all kinds of illnesses. Acupuncture has been used to treat ED for years. Studies show that acupuncture improves erection as well as in the treatment of erectile dysfunction with psychological cause.18

ED is often treated with psychotherapy, behavior modification techniques, oral medications, locally injected drugs, vacuum devices, and sometimes even surgically implanted devices. In rare cases, surgery of the blood vessels may be necessary. In most cases, even when a physical cause is identified, emotional or psychological factors play a role as well.
However, you might actually be better off going one step back in the chain reaction and taking an L-citrulline supplement. While your body converts L-arginine to nitric oxide, it also metabolizes it too fast when the amino acid is taken in an oral supplement, according to a 2011 study from the University of Foggia in Italy. L-citrulline, which the body converts to L-arginine, is actually a better option to follow the same metabolic pathway and serve as a treatment for ED, the same study found.
Issues relate to 'autoimmune type manifestations, joint pains, fatigue issues, rashes, sun-sensitivity, erectile dysfunction,libido issues, lack of energy and motivation, dry eye and sjogren's like symptoms, neuropathy for some, insomnia, etc. Any potential medications, therapies, or ways to approach these problems will be explored with great interest.

While there isn’t a lot of scientific evidence that supports using herbs to increase sexual urges, most of these supplements won’t hurt you. Try classic libido-enhancing herbs like maca, tribulus, rhodiola, ginseng, omega-3s, DHEA, and L-arginine. But be sure to consult your doctor first if you take blood thinners or other medications for heart health.
For many men, stopping smoking is an erectile dysfunction remedy, particularly when ED is the result of vascular disease, which occurs when blood supply to the penis becomes restricted because of blockage or narrowing of the arteries. Smoking and even smokeless tobacco can also cause the narrowing of important blood vessels and have the same negative impact.
