Hemorrhoids are the name for swollen veins in the rectum. They are extremely common in both men and women, and caused by a variety of factors, including your weight, diet, regular heavy lifting, constipation or straining during bowel movements. There are 2 different types of hemorrhoids; external and internal, both of which can cause pain, discomfort and bleeding.
Supplements that work to boost nitric oxide levels help with hemorrhoids as they can ease the anal pain, especially with external hemorrhoids. Nitric Oxide (NO) is the primary neurotransmitter of the internal anal sphincter (IAS) and as such boosting NO levels helps the IAS to relax, causing less pain.
