    Vitamin D and athletic performance

    Vitamin D, the sunshine vitamin, is well known for its role in bone health. Other roles include muscular and immune function, hence the interest for studying vitamin D and athletic performance. What is vitamin D Vitamin D is an essential fat-soluble vitamin (1). The active form of vitamin D is 1,25-dihydroxycholecaciferol (a.k.a. 1,25-dihydroxivitamin D) (2, 3), which interacts with vitamin D receptors (VDRs) (1). Sources of vitamin D Most of the vitamin D we get (80-90%, 4) is synthesised in our bodies from 7-dehydrocholesterol (2) after exposure to ultraviolet B (UVB) radiation from the sun (2, 4). The remaining 10-20% is obtained from the diet (4). Sunshine The actual amount…

    Iron deficiency anaemia

    Iron deficiency anaemia is a common health concern, particularly among females of child-bearing age. However, a person can be deficient in iron and not have anaemia. Conversely, not all anaemia cases are caused by iron deficiency. Iron deficiency is the most common nutrient deficiency (1). What is iron? Iron is a mineral present in multiple proteins in the human body, such as haemoglobin in red blood cells and myoglobin in muscles (1, 2, 3). Iron-containing proteins are key for oxygen transport, DNA synthesis, generation of energy by mitochondria (1, 3), enzymatic processes (1), immunity and cell signalling (3). Iron metabolism The equation below illustrates what happens with iron in our…
