Науковці закликають збільшити споживання вітаміну D для зменшення ризику ускладнень COVID-19
Він не рятує, коли людина вже захворіла – однак може істотно зменшити складність перебігу хвороби, якщо вживати його вдосталь заздалегідь:
Вітамін D суттєво зменшує серйозність перебігу COVID-19: результати перших рандомізованих випробовувань
Водночас, якщо його не вживали достатньо заздалегідь:
Вітамін D при лікуванні вже не допомагає важкохворим
У відкритому листі до міжнародних організацій, урядів, працівників охорони здоров'я науковці закликають сприяти збільшенню споживання населенням усіх країн вітаміну D.
Наукові дані показують, що він зменшує кількість інфікування та смертність від Covid-19.
Високий рівень споживання вітаміну D не гарантує безпеки, але водночас низький його рівень, брак в організмі, майже напевно пов'язаний з ризиком ускладнень, госпіталізації та смерті.
Вітамін D модулює багато аспектів імунної функції організму.
Уряди мають подбати про збільшення його споживання, нагально і масово. До того ж десятки досліджень показують, що його правильне споживання є безпечним, за дотримання дозування та рекомендацій. Ризик браку вітаміну значно перевищує будь-які ризики від інших способів лікування та запобігання інфікуванню.
Тому науковці закликають усі уряди, лікарів та працівників сфери охорони здоров'я в усьому світі нагально ввести заходи для збільшення споживання дорослими вітаміну D щонайменше до кінця пандемії.
Конкретні рекомендації для спеціалістів щодо дозування для різних категорій людей
Діяти слід негайно, наголошують науковці.
