Vitamin D3 400iu tablet view
Tablet Size
8mm round tablet

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.

Premium & All Natural Vitamin D3 Form

We use the premium and all natural form of Vitamin D, Cholecalciferol (Vitamin D3) in this supplement. Also available as higher-strength Vitamin D3 1000iu tablet.

Excellent service and competitive price
Service rating: The service from Just Vitamins is Just Marvellous! Products are top quality, extremely well paxkaged, and very competitively priced...I wouldn't dream of going anywhere else.
Product: Taking vitamin D3 as advised by the doctor. I have a skin condition which means I must stay out of the sun, and a recent blood test showed I was lacking in vitamin D. It's also advised for many older people to see them through the winter months too, so my wife actually takes it as well. All good!
Service rating: Speedy delivery, letterbox friendly packaging, competative prices.
Product: I take this supplement to improve my intake of Vitamin D. It is thought that in the Northern hemisphere we have inadequate amounts of sunlight resulting in potential low levels of vit D in our bodies.

Website easy to use, easy to order, quick delivery.

Service rating: A good product, at a good price. Sensibly packed and quickly delivered. I would certainly buy from them again and recommend them to friends and family.
Product: I used to have Vitamin D tablets with Calcium prescribed by my NHS GP. Being an oldie, my prescriptions cost me nothing. Suddenly I have been told that I can buy them more cheaply on the internet! She won't prescribe them any longer. Obviously I feel a bit aggrieved, but at least I can get a good supply from Just Vitamins.
