Vitamin D helps to build strong bones and healthy teeth. Commonly known as the sunshine vitamin, Vitamin D is synthesized in the skin following exposure to sunlight. 

Ideal for boosting Vitamin D levels during the winter months

Most healthy adults should be able to get enough Vitamin D from being outside in the sun, unfortunately in the UK in the winter there isn’t much opportunity to get a daily dose of sunshine! This strength tablet is the ideal daily dosage for healthy adults who wish to maintain optimal vitamin D levels and is suitable for children over the age of 5 years old and pregnant women.

Recommended by the Food Standards Agency

The Food Standards Agency recommends that if you are pregnant or breastfeeding you should take a 400iu/ 10µg supplement of Vitamin D each day.

Older people should also consider taking 400iu/10µg of Vitamin D each day. Others who may be at risk from Vitamin D deficiency include people who:
  • are of Asian origin
  • rarely get outdoors   
  • eat no meat or oily fish

If you aren't getting enough Vitamin D, you might be more at risk of some of the harmful effects of too much Vitamin A.

Provides 100% NRV in a small easy swallow tablet

Our 400iu Vitamin D tablet provides 10µg (100% Nutrient Reference Value) in a small easy to swallow tablet. The UK Department of Health recommends that anyone at risk of a Vitamin D deficiency take between 400iu to 800iu per day to maintain healthy Vitamin D levels throughout the year. Read more in the paper produced by the UK Department Of Health on Vitamin D deficiency here.

Service rating: Quick and reliable service
Product: Good price. Fast delivery
Service rating: Good price with quick and easy delivery
Product: My diet provides me with all the vitamins I need, except for vitamin D, which comes mainly through the action of sunshine on our skin. In the winter especially when we stay indoors and cover ourselves we don't get enough of it. After feeling exhausted all the time a few Springs ago, I was diagnosed by my doctor as having low levels of it. I started taking it and felt normal again. I now make sure I take a maintenance dose all year. It's the one vitamin the NHS recommends us taking!
