In modern societies, many people may be at risk of low vitamin D levels, so testing serum 25-hydroxy-vitamin D (25OH-D) levels before prescribing supplementation is crucial. In emergency situations, patients should be advised to take moderate vitamin D doses and have their 25-OH-D levels checked later.
Nowadays, in modern societies, many people can be at high risk to have low vitamin D levels. Therefore, testing of serum 25-hydroxy-vitamin D (25OH-D) levels should be performed before prescribing them vitamin D supplementation. However, in some cases the 25OH-D level assessment is not available at the right moment, e.g., due to mandatory quarantine of COVID-19 outpatients. Therefore, such patients could be advised to start taking moderate vitamin D doses (e.g., 4000 IU/day for adults), and their 25-OH-D levels could be checked later. The proposed algorithm also comprises vitamin D dosing principles when baseline 25OH-D levels are known.
