Vitamin D supplements are now routinely recommended for all who are spending time indoors of 10 micrograms daily, by Public Health England. This advice was updated during lockdown but many people are still spending long periods inside, hence the advice is still very important, even during summer months. There are various forms of vitamin D (spray, tablets, capsules, gummies), so take your pick! Upper safe limit for self-supplementation is 75mcg in the UK and higher intakes may be recommended under supervision of a practitioner. GPs now routinely offer blood tests for vitamin D, such is its importance in our health. There are also many cost-effective tests available privately so blood levels can be easily monitored and supplementation adjusted if needed.
