Vitamin D is needed for the body to absorb calcium and phosphorous, and so plays a vital role in the growth and maintenance of strong bones and teeth. This essential mineral also helps to strengthen the immune system and promotes healthy muscle function, while there is evidence from large-scale clinical trials to suggest that vitamin D may help to reduce the risk of dementia. Because natural food sources of vitamin D are rare, the most effective ways to receive adequate levels are through sunlight exposure and supplements.
Findings from a recent survey suggest that 2 out of 3 adults living in the UK have vitamin D levels considerably lower than advised. To help raise awareness of this issue, the Department of Health has identified ‘at-risk’ groups who are often at an increased risk of deficiency, including adults over the age of 65, pregnant or breastfeeding women, and adults who have limited exposure to sunlight. They advise taking between 400iu to 800iu per day to maintain healthy vitamin D levels throughout the year.
Our high-strength vitamin D tablets are Good Manufacturing Practice (GMP) approved to ensure they meet strict standards of quality. This 400iu strength 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. If you are concerned about weakening bones, you may wish to try our super-strength Vitamin D 2000iu tablets.

The vitamin D I have taken has put my system back on track but my consultant wants me to up the dosage from 800iu to 2000iu because of continuing low levels of Vit D.

|Q:||Do you plan on selling vitamin D3?|
Studies show that vitamin D2 is just as effective as D3 when taken as lower strengths such as 400iu. Only when taken at super strengths between 1000iu and 2000iu, is vitamin D3 better absorbed by the body.
Following these guidelines, we offer a Vitamin D2 400iu, and a separate Super Strength Vitamin D3 2000iu supplement.
