Atherosclerosis, a condition in which fatty deposits build up inside arteries, may restrict blood flow to the penis and cause erection difficulties. "The small blood vessels that go to the penis can become diseased much earlier than the [larger] vessels that go to the heart," Karen Boyle, MD, a urologist at Johns Hopkins School of Medicine, tells WebMD. "In younger or younger middle-aged men, ED is often the first sign of atherosclerosis."
Male enhancement supplements work by increasing the amount of blood flow the genital region receives and the volume of blood that it can retain. In a flaccid state, the penis, like any other part of the body, receives a normal amount of blood flow. When an erection occurs, the penis is surged with a rich supply of blood which is then trapped in the spongy tissues of the Cavernosa and Spongiosum.
Those who do not like the idea of taking a tablet every day can take liquid supplements. Liquid supplements contain the same ingredients found in the tablets. Instead of taking a single capsule every day, you simply drink a small amount of the liquid. Nutritional supplements come in several flavors, including a traditional flavor and a citrus flavor. You can drink the male enhancement liquid straight from the bottle, but some men prefer mixing the liquid supplement with water or another drink. The liquid products have the same benefits as the tablets and capsules.
