Why Choose Us

Vitamin D is naturally manufactured when sunlight hits our skin. This explains why it is known as the sunshine vitamin. This essential nutrient has several important jobs which include regulating levels of calcium in the body, supporting the immune system and muscle function as well as contributing towards healthy bones and teeth.

Between October and March the levels of sunlight in the UK aren’t sufficient for us to make enough vitamin D. Public Health England recommends that during these months people should take a supplement to top up their levels.

This Vitamin D supplement is delivered as Vitamin D3, which is the most absorbable and effective form of this nutrient.

Why choose us

Our 4000iu high-strength Vitamin D3 supplement provides excellent quality nutrition for outstanding value.

Each bottle provides a 14 month supply of 425 very easy-to-swallow, odourless, tasteless, soft-gel capsules.

VitaBright supplements are produced in state-of-the-art, BRC accredited grade AA, UK manufacturing facilities operating to GMP standards. We use only the finest ingredients, double seal all bottles, and test for heavy metals to ensure there is no compromise on quality or safety.

Vitabright vitamin d3

I would highly recommend vitabright vitamin d3 the purchase was easy ,the product came very quickly and was packaged well and the d3 capsules are easy to swallow and do exactly what they are supposed to do very high quality and I'm a very happy customer

Beverley Levy
Excellent value, I think.

These capsules are a really nice size, small, and very easy to swallow. I've researched dosage levels for vitamin D3, and am still unclear on how much I really need to take daily, but feel regularly taking 4000 IU a day may be too much, so I take one capsule every second or third day. At this rate, this one bottle will last for two or three years. Now that's what I call excellent value.

Like them

I did a lot of research and found that these seem to be the best quality ingredients and the best value, I'd recommend them if you should be taking vitamin D (as most people should in the UK)


The real deal. After wasting years taking a supplement that gave us nothing, one week on VitaBright had my very disabled wife confused as to why she suddenly had more energy.

Barry Stocking

So far so good.
