What Physician Assistants Do. Physician assistants, also known as PAs, practice medicine on a team under the supervision of physicians and surgeons. They are formally educated to examine patients, diagnose injuries and illnesses, and provide treatment.he work of physician assistants depends in large part on their specialty and what their supervising physician needs them to do. For example, a physician assistant working in surgery may close incisions and provide care before and after the operation.
Overview. Vitamin B12, also called cobalamin, is one of 8 B vitamins. All B vitamins help the body convert food (carbohydrates) into fuel (glucose), which is used to produce energy. These B vitamins, often referred to as B complex vitamins, also help the body use fats and protein.egetarians who do not eat any animal products should take a vitamin B12 supplement with water, preferably after eating. Elderly people may need larger amounts of vitamin B12 than younger people because the body's ability to absorb vitamin B12 from the diet goes down with age.
A B Complex that includes 250 mcg of B12 as cyanocobalamin daily should be enough for you to absorb what you need to maintain healthy levels. (As per Dr. Michael Greger's latest recommendations .). To correct a deficiency, take something in the range of 1000-2000mcg per day.ore recent studies put the ideal intake at 4-7 mcg per day. (Click for more info on optimum levels .). The trouble is our bodies don't absorb all of the B12 we take, and there's kind of a cap on how much we absorb at one time.
