Welcome to the Vitamin Deficiency and Benefits of Vitamin Supplementation for Human Health Webinar!
Vitamins are essential nutrients that the body needs to function properly. Intake via the diet is often inadequate compared to recommendations, and this is an issue in developing countries and also in industrialized countries for some vitamins. A person may not be aware or ‘feel’ of their poor vitamin status early-on, nor does it present any other symptoms; rather, it impacts human health later on in life (triage theory). Intake data are developed via questionnaires, presenting risks of under- or over-reporting. As such, it is more accurate to measure the status of vitamins in the body. Status data are more important because they reflect the actual situation in humans. Statistics on a suboptimal nutrient status provides individuals with information to act and address nutritional disruption.
Intake recommendations for vitamins are science-based and are often defined to avoid deficiencies; they differ for different age groups, sexes, and risk groups, for example for pregnant and lactating women, or the elderly. Intake recommendations are defined for healthy people, and in clinical conditions, there is insufficient research on vitamin depletion and deficiency, leading to inadequate treatment recommendations that do not consider the role that vitamins play in reducing the risks of diseases that require higher recommendations. An optimal nutritional status provides many health benefits. The webinar examples present cut-off points developed for deficiency, suboptimal status, and optimal vitamin status. Furthermore, biomarkers can importantly be used in this context to assess vitamin status. Finally, in the webinar examples, the benefits of optimal vitamin status for long-term health are presented.

This webinar emphasized the importance of vitamin intake for proper bodily function, comparing vitamin status between industrialized and developing countries. It also highlighted the significance of clinical situations, especially for patients who have undergone surgical procedures, in influencing vitamin levels.
