Fæðubætiefni

Fæðubætiefni, also known as dietary supplements, are products intended to supplement the diet. They are typically consumed orally and can include a variety of ingredients such as vitamins, minerals, herbs, amino acids, enzymes, and other substances. The purpose of a dietary supplement is to provide nutrients that might not be consumed in sufficient quantities through food alone, or to support specific health goals.

In many countries, dietary supplements are regulated differently than pharmaceutical drugs. They are generally not required to prove efficacy or safety before being marketed, though regulatory bodies may take action against products found to be harmful or mislabeled. Manufacturers are responsible for ensuring their products are safe and that any claims made are truthful and not misleading.

Commonly used supplements include multivitamins, vitamin D, calcium, omega-3 fatty acids, and probiotics. People may choose to take supplements for a variety of reasons, including to address perceived nutritional deficiencies, to support athletic performance, or to manage specific health conditions. However, it is generally recommended that individuals obtain most of their nutrients from a balanced diet. Consulting a healthcare professional before starting any new supplement regimen is advisable to ensure it is appropriate for individual needs and to avoid potential interactions with medications or existing health conditions.
