A Deficiency Epidemic

Vitamin D is thought by most health experts to be the most important vitamin for those with chronic health conditions. However, a deficiency in this vitamin is incredibly common, with some studies estimating that one billion people worldwide have insufficient levels.

This deficiency occurs because we get the majority of our vitamin D from the sun. Therefore, those of us who live in less sunny climates (such as the UK) are very likely be to deficient unless we use appropriate supplementation.

Vitamin D plays a critical role in many areas of our health. For example, if someone is deficient, studies have shown that it will adversely affect their immune system and can be a key component in someone developing an autoimmune condition (such as Crohn’s, Ulcerative Colitis, Rheumatoid Arthritis or Psoriasis).

Advanced D3 provides you with Vitamin D in its most useful, absorbable form. What's more, unlike most other products, it is produced to the highest possible manufacturing standards (GMP and ISO:9001) so quality is assured. So much so that you are protected by our unrivalled 90 day moneyback guarantee.

Frequently Asked Questions

When should I take Advanced D3 ?

Because we've contained Advanced D3 within an easy swallow tablet, it can be taken at any time of day with any type of food or drink. We suggest taking it with meals for greater effectiveness, normally at breakfast if possible.

How Many Pots Should I Order?

There is a large amount of research available showing the huge importance of vitamin D supplementation on your health, gut, bones, heart, and immune system. Therefore, we believe that the majority of people would benefit from using this product daily, on an ongoing basis, especially if you aren’t regularly getting full body exposure to the sun (which in the UK is practically impossible for much of the year). With that said, you will save money today taking advantage of our special 3 and 6 bottle discounted packages. These also allow you to take advantage of up to 20% savings, without the worry of increasing prices and/or the addition of postage fees later on. And you’re completely protected by our 90 day moneyback guarantee.

How do I use this product?

Simply take 1-5 capsules per day, with or without food. A higher dose is generally required for those who do not get regular full body exposure to the sun. A typical dose for someone in the UK who gets an average amount of sun would be 2 per day.

However, we always recommend that if you take prescription medications, have a medical condition, or are pregnant or breastfeeding then you show a bottle to your doctor and/or pharmacist for proper approval prior to using it.
