The correct name for vitamin e niacin is vitamin E nicotinate, which is not available clinically as a tablet, but is available in capsule, softgel, and gelatin pill form. Vitamin E has antioxidant properties that protect cell membranes from free radical damage. Niacin inhibits the synthesis of very low density lipoproteins, thereby reducing plasma lipoprotein levels. It is used clinically for the prevention of hyperlipidemia or atherosclerosis.
Niacin is acidic and can cause gastrointestinal irritation after administration. It can also cause adverse reactions such as skin and facial flushing and headache. Note that it is contraindicated in patients with chronic active liver disease and active peptic ulcers. Niacin also inhibits the excretion of uric acid from the body, so it is contraindicated in patients with severe gout.
Patients need to use under the guidance of a medical professional, do not take medication without authorization.
