Supplement Description

Our Vitamin D3 4000iu is the optimum level recommended by nutritionists to quickly correct deficiency. Vitamin D supplementation can play an important role in correcting Vitamin D deficiency to ensure the maintenance of adequate levels in the body.

Vitamin D plays a number of crucial roles in the body including providing support for immune health, muscle health and strong bones and teeth. Vitamin D can be obtained through food sources such as eggs, fortified cereals and oily fish, but is predominantly synthesised in the skin through exposure to sunlight - hence why it is often referred to as the 'sunshine vitamin'.

Most healthy adults should theoretically be able to get enough Vitamin D from being outside in the sunshine, however Vitamin D deficiency is very common throughout the UK. This is as a result of a low level of exposure to sunlight, making Vitamin D synthesis almost impossible during the winter.

High strength, natural form tablet

Our 4000iu high strength Vitamin D supplement provides 100µg (2000% Nutrient Reference Value) in an 8mm round, odourless tablet with no coating. We use a high quality natural form of Vitamin D, Cholecalciferol (Vitamin D3) in this supplement - the form of Vitamin D most readily absorbed by the body. Our manufacturing process gives us a highly concentrated form of Vitamin D3 which offers 99% purity and unbeatable quality.

Recommended as a food supplement by the FSA

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

People 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

Vitamin D and rickets in children

Vitamin D is crucial for the maintenance of health and strong bones, a deficiency in Vitamin D can cause rickets in young children which is a weakening and softening of bones which can lead to bone deformities. After World War II instances of rickets in the UK were dramatically fewer due to the British government introducing cod liver oil as a supplement - this is a great food source of Vitamin D. However between 2003 and 2013 the NHS reported a 430% increase in cases of rickets, an alarming statistic highlighting a growing health problem.
