    We read with interest Martin Kohlmeier’s article in which he highlights the need for precision nutrition (PN) for vulnerable individuals, amongst them people with darker skin tones. In the UK, a disproportionate effect of Covid-19 on BAME (Black, Asians & Minority Ethnic) has been noticed. (1)(2) With the epidemic still rampant some immediate action is needed. Vitamin D deficiency is not only high among ethnic minorities but also among the elderly. (2)(3) It has been linked to potential worse outcomes in many infectious diseases. (4) In a preprint Alipio documents a possible improvement of clinical outcomes in Covid-19 with vitamin D supplementation. (5) Ilie et al. describe association between mean vitamin D levels and COVID morbidity and mortality in 20 European countries. (3) During my clinical round on our COVID ward on 12/5/20 I found 18/23 patients Vitamin D deficient, 2 died that day, their vitamin D levels had been undetectable. We will explore this further by collecting a larger dataset. Supplementation with vitamin D up to 800 IU daily is safe and should be highly recommended to BAME people, even more so for those who are healthcare workers. Similarly, vitamin D substitution should be recommended for all healthcare workers, the over 70’s, the institutionalised, the pregnant, adolescent, under 3 years and the obese. (6) COVID-19 should be a wake-up call for the elimination of this widespread vitamin deficiency.
