## Features

- X4 STRENGTH D3 - Our extra high strength Vitamin D3 4000 IU supplement is one of the most powerful formulations available.

Our tablets are suitable for vegetarians and contain no GMO ingredients or allergens such as gluten, lactose or soy.
- BOTTLED SUNSHINE - Vitamin D is an essential nutrient for our overall health and wellbeing. We know that exposure to sunlight is the most common source of obtaining it but it can be difficult to maintain levels, particularly in the colder months, which is why the NHS recommends supplementing during Autumn and Winter.

- FOR IMMUNE & BONE HEALTH - Vitamin D is a wonderful nutrient that helps to keep our immune system defences in balance. It contributes to the normal function of the immune system as well as to the maintenance of normal bones, teeth, muscle function and the normal absorption/utilisation of calcium and phosphorus* which are all important to maintaining our overall health and wellbeing. Our Vitamin D is made in the UK to current GMP standards and meets stringent UK/EU legislation and testing.
