Say Goodbye to Erectile Dysfunction with Tadalafil

Erectile dysfunction, abbreviated ED, and otherwise known as impotence in men, is the failure of a man to obtain and maintain an erection which is direly needed for engaging in sexual intercourse.

Erectile dysfunction is a condition that is very common in much older men.  It has been estimated that about half of all men who are within the bracket age of 40 to 70 may have ED at a certain degree.  Depending on the circumstances and on the individual himself, erectile dysfunction can also affect those who are younger, even if they are just around the age of 25 or more.

Why does ED Occur in some Men?  Erectile dysfunction causes actually vary, and they can be physically related or psychologically related.  Physical causes of ED may include hormonal issues, surgery or injury, tightening of the blood vessels that lead towards the penis which is usually linked to high cholesterol, hypertension, or diabetes.  Psychological (mental) causes of ED may include depression, anxiety or problems with relationships.

Stats Can meets Dr. Sunshine

It's official, about 10% of the population has inadequate concentrations of vitamin D and, of these, 1.1 million Canadians are vitamin D deficient -- this according to a Stats Can report released today. Men are more likely to be deficient than women, especially males under age 40.

The agency defined vitamin D deficiency as a concentration below 27.5 nanomoles per litre (nmol/L) — a measurement of concentration based on the number of molecules per litre of blood.

American dermatologist Michael "Dr Sunshine" Holick, the author of the new book "The Vitamin D Solution" blames The American Academy of Dermatology he told the New York Times this past weekend. He knocks the Academy for their recommendation that "that you should never be exposed to one ray of direct sunshine without sun protection." He suggests that the Academy is "heavily invested" in the cosmetic industry.

He recommends 2000 IU Ds a day and suggests you can get it by spending 15-30 minutes a day sunning your arms and legs. Why the legs? Because they comprise almost 40% of the skin's surface. He strongly recommends that you always protect your face with sunscreen.

Fired from the University of Boston because of his sunshine advocacy, he remains a controversial figure. For example, the new book's cover touts the vitamin for eveything from depression to autism. In the he latter case says it will help as an improvement to muscle function.

Not surprisingly he recommends that everyone take a supplement. There may soon be confirmation from Stats Can. Future analysis of the data will investigate factors that may influence vitamin D concentrations, such as supplement consumption, body mass index, pregnancy, fish consumption and use of sunscreen. the researchers. said.

The evidence for the benefits from vitamin D is nothing short of astonishing and keeps coming in. From helping to ward off cancer to possibly curing the common cold to preventing influenza and other positive findings, the sunshine vitamin has a bright future indeed. When you throw in that becuase of poor diet and a modern lifestyle which decreases exposure to sunshine average vitamin D levels are likely lower than in the past, it is not a stretch to speculate that very many of the diseases of modern society may be directly related to or partially influenced by a deficiency of this lion of a vitamin. There is a little bit of an intro to the topic here,
