Summary
This chapter synthesises current knowledge on the essential micronutrients sulfur and selenium, examining their roles as components of amino acids and selenoproteins integrated into major metabolic pathways. The review covers dietary sources, human requirements, the health consequences of both insufficiency and excess intake, and the evidence base for supplementation strategies.
Regional applicability
As a narrative review of fundamental nutrition biology without geographic specificity, the findings on sulfur and selenium biochemistry and human requirements apply broadly, including to United Kingdom populations. However, specific dietary source recommendations and deficiency prevalence may vary by regional food production and dietary patterns.
Key measures
Sulfur amino acids, selenocysteine incorporation, metabolic pathways, dietary sources, nutritional requirements, deficiency and excess effects
Outcomes reported
The chapter reviews the nutritional biology of sulfur and selenium, their dietary sources, human nutritional requirements, effects of deficiency and excess, and supplementation rationale for human health.
