Derived from algae, use our easy to swallow capsules to help prevent deficiency of this important nutrient. Needed for immunity, healthy bones, teeth, muscles and more besides. This is one vitamin you really don’t want to be short on. Vitamin D is a firm favourite of our expert nutritionists who consider it a vital cornerstone to health. Many of us are low in vitamin D either because we spend our days inside or we cover up and stay out of the sun when outside. Vitamin D is made naturally by the action of sunlight on the skin, which is why its often dubbed the sunshine vitamin. Darker skin tones produce less vitamin D when in the weaker sunlight of the northern latitudes as their additional melanin pigment inhibits production. Come autumn and winter even spending time outside on a bright day doesn’t produce vitamin D whatever your skin tone. No wonder many of us are deficient.Public Health Engla
