Are You Getting Enough Vitamin D in Lockdown?

Vitamin D is well known as the ‘sunshine vitamin’ and is responsible for many important functions within the body. But, are we getting enough?

For most people, lockdown will mean being indoors for much of the day. Many people are not fortunate enough to have a garden and with only one walk a day we are limited to the amount of sunshine we can get at the moment.

Under normal circumstances from about April to the end of September, most people should be able to get all the vitamin D they need from sunlight but now we are forced to spend most of our time indoors there is an increased risk of developing a vitamin D deficiency as we may not be getting enough sunlight to replenish our levels.

The Public Health Agency has recommended that people supplement with vitamin D supplements during lockdown.

“As a result of being inside more, we may not be getting enough vitamin D from sunlight. We are advising that everyone should consider taking a supplement of vitamin D every day to keep their bones, teeth and muscles healthy.” Caroline Bloomfield, The Public Health Agency (PHA) lead on Nutrition and Healthy Eating

It is vital that we get enough of this important hormone as vitamin D has many important functions within the body and plays a vital role in:

Immunity which plays an important role supporting the immune system.

Hormonal health by balancing our sex hormones

Supporting a healthy digestive system

Bone health, as vitamin D regulates the amount of calcium and phosphate in the body, both needed for healthy bones, teeth and muscle (1) .

Improving brain development and function

Vitamin D is an essential vitamin for everyone and we get it from two main sources, sunlight and food such as oily fish, egg yolks and mushrooms

There are two types of vitamin D. Vitamin D2 (ergocalciferol) from plant sources, i.e. mushrooms, and vitamin D3 (cholecalciferol) from animal sources such as oily fish and egg yolks as well as the supplemental forms. Vitamin D3 is the more powerful of the two types as it is bioavailable and raises blood levels of vitamin D almost twice as much as D2 (2) .

A blood test can determine your current levels so you know what dosage you need to take. The blood levels of vitamin D are assessed by measuring 25(OH) D - 25-hydroxy vitamin D in the blood (3) .

Public Health England vitamin D recommendations

Public health England have recently increased the recommended level to 25ug/day during the current pandemic. PHE normally recommends everyone in the general population aged 4 years and older to have 10 micrograms (400UI) of vitamin D daily, throughout the year. This includes pregnant and breastfeeding women and population groups at increased risk of vitamin D deficiency. For all infants from birth to 1 year of age 8.5 to 10 micrograms (340-400 IU/d) of vitamin D per day is recommended; however, children who have more than 500ml of milk (including baby milk formula) every day do not need any additional vitamin D.

There are many vitamin D supplements on the market but sprays/drops are more easily absorbed rather than tablets or capsules and also drops are easier for children to take.
