Vitamer vs. Vitamin — What's the Difference?
By Urooj Arif & Fiza Rafique — Updated on May 7, 2024
Vitamers are various chemical compounds that show the biological activity of a specific vitamin, while a vitamin is a broader category encompassing all vitamers that fulfill the same essential nutritional role.

Key Differences
Vitamers are specific forms or chemical compounds that represent one type of vitamin. Each vitamer can vary in its chemical structure but still offers the same vitamin activity. Whereas a vitamin is a more general term for essential nutrients required in small amounts for various bodily functions, including multiple vitamers.
For example, Vitamin B3 includes several vitamers such as niacin and niacinamide, both of which prevent pellagra and serve similar biological functions. On the other hand, referring to Vitamin B3 generally doesn't specify the form, encompassing all its vitamers.
Vitamers can have slightly different properties and bioavailability, which refers to how well the body can absorb and use them. Whereas the term vitamin refers to the overall function and necessity of the nutrient, without indicating these specific differences.
In dietary terms, understanding vitamers can be important for nutritional science and diet planning, as some forms might be preferable or more effective based on individual health conditions or dietary sources. Meanwhile, vitamins are discussed in broader dietary guidelines and recommendations, focusing on ensuring an adequate intake of each vitamin.
In supplementation and fortification, specific vitamers are chosen for their stability and effectiveness. For example, different forms of Vitamin D are used in dietary supplements due to their potency and metabolic effects. However, vitamin labels generally only specify the vitamin type, not the vitamer.

Compare with Definitions
Vitamer
A specific form of a vitamin.
Pyridoxal, pyridoxamine, and pyridoxine are vitamers of Vitamin B6.
Vitamin
Defined by their necessity in preventing specific deficiencies.
Vitamin K prevents bleeding disorders.
Vitamer
Chemically distinct compounds with similar functions.
Ascorbic acid is a vitamer of Vitamin C.
Vitamin
Classified by solubility: water-soluble or fat-soluble.
Vitamin B12 is water-soluble, while Vitamin K is fat-soluble.
Vitamer
Varies in absorption and conversion rates.
Different vitamers of Vitamin E are absorbed at different efficiencies.
Vitamin
Essential organic compounds required in diets.
Vitamin D is crucial for calcium absorption and bone health.
Vitamer
Determines specific clinical applications.
Certain vitamers of Vitamin D are used for treating deficiencies.
Vitamin
Cannot generally be synthesized by the body.
Vitamin C must be ingested through fruits and vegetables.
Vitamer
Used specifically in nutritional supplements.
Retinyl palmitate, a vitamer of Vitamin A, is commonly used in supplements.
Vitamin
Necessary for metabolic and physiological functions.
Vitamin A is essential for vision and immune function.
Vitamer
Vitamins occur in a variety of related forms known as vitamers. A vitamer () of a particular vitamin is one of several related compounds that exhibit biological activity against a specific vitamin deficiency.Early research identified vitamins by their ability to cure vitamin-specific deficiency diseases.
Vitamin
A vitamin is an organic molecule (or a set of molecules closely related chemically, i.e. vitamers) that is an essential micronutrient which an organism needs in small quantities for the proper functioning of its metabolism.
Vitamer
One of two or more related chemical substances that fulfill the same specific vitamin function.
Vitamin
Any of various fat-soluble or water-soluble organic substances that are essential in minute amounts for normal growth and activity of living organisms. They are synthesized by bacteria and plants and are obtained by animals chiefly in their diet.
Vitamer
Any of a combination of substances that, together, function as a vitamin.
Vitamin
A preparation containing one or more vitamins, often taken as a dietary supplement.
Vitamin
Any of a specific group of organic compounds essential in small quantities for healthy human growth, metabolism, development, and body function; found in minute amounts in plant and animal foods or sometimes produced synthetically; deficiencies of specific vitamins produce specific disorders.
A food rich in vitamins
Vitamin
Any of several organic chemical substances not synthesized by an animal and required in small quantities for normal metabolism, present in and obtained from the natural foods eaten by the animal. Human vitamins are also produced synthetically, and taken in pure form or in mixtures, as dietary supplements. Deficiencies of specific vitamins lead to certain specific disorders, such as scurvy, caused by an insufficiency of vitamin C (ascorbic acid).
Vitamin
Any of a group of organic substances essential in small quantities to normal metabolism
