High-dose Vitamin D3 4000 IU capsules

A high-potency vitamin D supplement, Essentials Vitamin D3 4000 IU contains 100 μg of top-quality nature-derived vitamin D3 from lanolin. It’s delivered in small, easy-to-swallow cellulose capsules.

Current research suggests consuming up to 4000 IU of vitamin D per day should be ideal for optimal blood levels in most people. Taking more than 4000 IU may provide no extra health benefits.

Essentials Vitamin D3 4000 IU benefits

Essentials Vitamin D3 4000 IU capsules contain the best possible form of vitamin D3 (cholecalciferol) and have a quick dissolution time, which guarantees optimum absorption and benefits.

The capsule shells are plant-based, GMO-free and contain NO colourings, preservatives or allergens, which is why they’re also suitable for vegetarians and people with allergies to gluten, lactose, soy and others (see Properties at the very end).

Vitamin D plays many crucial roles in your body: 

  • boosts immune system,

  • helps maintain muscle function,

  • supports normal cell division,

  • upkeeps density of bones and teeth,

  • contributes to normal absorption and utilisation of calcium and phosphorus.

Vitamin D deficiency

Estimates suggest that over 1 billion people worldwide are vitamin D deficient or insufficient. In UK, around 27% of people have insufficient or deficient vitamin D levels, while as many as 74% don’t meet the recommended vitamin D levels for optimum wellbeing.

A major cause of vitamin D deficiency is limited exposure to sunlight due to spending a lot of time indoors, living in northern latitudes, wearing long robes or coverings, or lack of UVB radiation from sunlight (from late autumn through winter to early spring). Other risk factors include:

  • having dark skin,

  • wearing sunscreen,

  • being overweight,

  • ageing (especially problematic for age 60+),

  • having certain health conditions (like celiac disease, Crohn’s disease, cystic fibrosis), and

  • having low vitamin D intake.

Vitamin D3 works best with vitamin K2

Regular vitamin D supplementation can result in a higher demand for vitamin K2 – here’s why. Vitamin D3 increases the absorption of calcium into the bloodstream. Vitamin K2 helps transport and bind calcium to your bones, preventing it from sticking to your artery walls.

That’s why we recommend combining Essentials Vitamin D3 4000 IU with Essentials Vitamin K2 that contains 200 µg of vitamin K2 in the best possible, biologically active MK-7 form.
