What it is and how it works
Dietary supplements come in various forms, including vitamins, minerals, herbal products, and probiotics. Each type is intended to provide nutrients or compounds that might be lacking or insufficient in a person’s diet. For example, vitamins are organic compounds essential for normal growth and metabolism, while minerals are inorganic elements that support bodily functions.
The way supplements work depends on their specific type and ingredients. Vitamins and minerals often act as cofactors in enzymatic reactions, helping the body convert food into energy or maintain healthy tissues. Herbal products contain plant-based compounds that have been studied for their potential to support health in different ways, such as reducing inflammation or promoting relaxation. Probiotics are live microorganisms that might support digestive health by balancing gut bacteria.

If nausea occurs, it might help to take supplements with food or try a different formulation, but these approaches should be discussed with a healthcare professional. Understanding the cause of nausea is important, as it could be related to other factors beyond the supplement itself.

What the research says
Research on whether it is normal to feel nauseous after vitamins shows mixed results.

If nausea occurs after taking vitamins, it might support discussing this symptom with a healthcare professional to explore possible causes and appropriate management. This approach helps ensure safe and effective use of dietary supplements.
Possible benefits
Dietary supplements have been studied for a variety of potential health effects, though evidence can be limited or mixed. Some supplements might support general wellness by providing nutrients that are otherwise difficult to obtain from diet alone.
