Aside from keeping your blood cells and nerves healthy, vitamin B12 plays a role in the production and development of sperm. A deficiency can mean problems like loss of libido and premature ejaculation. B12 supplementation may help improve sperm count, concentration, and motility in men with fertility issues. An adult needs about 2.4 mg B12 every day for the healthy functioning of the body.
Vitamin B12 is found naturally only in foods of animal origin – shellfish like oysters and clams; fish like mackerel, herring, and tuna; red meat; beef, pork, and chicken liver; and goose, duck, and chicken eggs. Vegetarians can have silken tofu, Swiss cheese, milk, and yogurt, while vegans can have fortified bran flakes. Have at least 6 mcg B12 a day.
Hypotension is blood pressure (BP) below 90/60 mmHG. Usually, low BP alone is not unhealthy, and some people may have it all the time. But it becomes a cause of worry if it makes blood flow to the brain and vital organs inadequate and manifests as clammy skin, blurry vision, dizziness, or is linked to a health condition like heart disease. Its most severe and fatal form is shock, where the patient can even get a stroke or heart attack.
Getting vitamin B12 through food is a major challenge for vegans as the skin of white button mushroom is the only natural source of absorbable B12. Seaweed, nori, and miso are best avoided as they contain inactive versions of B12 that hinder active B12 absorption. The other options are fortified cereals, rice, plant-based milk, and supplements, which should be taken in small doses for maximum absorption.
