    Nutrients Uncovered: How much vit D do I really need?

    Why is Vitamin D Important?

    We produce vitamin D when we expose our skin to strong sunlight. Experts suggest up to 50% of UK adults are deficient due to limited sun exposure.

    It works in many ways within the body, it increases the absorption of calcium from food, ensuring healthy bones and teeth. It also helps to maintain healthy muscles and a healthy immune system. Good levels of the vitamin have been linked to reduced joint pain and improved exercise capacity, most recently vit D has shown to positively affect the health of heart failure patients.


    Small quantities of the vitamin can be found in foods such as oily fish, eggs, meat and milk however it is very difficult to get the sufficient amount of this essential vitamin without regular exposure to strong sunlight, or by taking a supplement.

    How much does your body need?

    Although the amount of vit D required by each individual can vary, as a guide we would recommend the following dosages:

    • 800 IU (20micrograms) – Teens / Adolescents, 1-2 tablets per day
    • 1000 IU (25 micrograms) – Adults, 1-2 tablets per day
    • 5000 IU (200 micrograms) – Deficient adults, 1 tablet per day

    For a more accurate dosage requirement, we would advise getting a Vitamin D3 deficiency test from your doctor.
