Dietary Suitability & Accreditations

Quality Assured Lactose Free Gluten Free Good Manufacturing Practice No Artificial Colours or Flavours Non GMO

These two essential nutrients work really well together to enhance each other's benefits, however, they also compete for absorption in the gut, which means they are not well-absorbed if taken at the same time.

For the best results, take these supplements at least 1 or 2 hours apart. Taking shortly before or after a meal containing a significant amount of fat content will further boost absorption.

    Why are they so Good Together?

    Calcium, the most abundant mineral in the body, is essential to many body processes. Vitamin D, and in particular vitamin D3, helps you absorb calcium more effectively.

    Vitamin K2 plays an essential role in blood clotting, heart health, bone health, and  helps to distribute calcium around the body to where it is most beneficial.


    Why Choose Us?

    Our vitamin D3 & K2 capsules are of the highest quality, formulated using only the finest ingredients and UK manufactured to GMP standards.

    Both supplements are very easy to swallow, non-GMO and free from additives.

    We supply these nutrients separately for optimal absorption and to allow customers to manage their dosages individually throughout the changing seasons (Less vitamin D may be required in the summer months).

    For the best results, take these supplements at different times of the day. Taking alongside a meal containing a decent amount of fat will boost absorption.

    14 month supply

    Can’t say whether these are working for me yet, but they are good value for money. I think it takes longer than a month to notice a difference! I think it might be a good idea to take this supplement for anyone not living in a sunny climate. I still think the best way to get vitamin D is to get out in the sunshine as much as possible!

    Wonderful Combo

    I was advised by my doctor to take D3 as my levels were low. After researching, I found out you have to take K2 alongside D3, for the best results, since K2 absorbs vitamin D3. VitaBright have a great deal on a combo of D3 and K2 for an amazing price

    Great Supplement

    A great supplement. I've been taking these for over a year now and I'm sure they've helped ward off any potential viruses

    I recommend

    The D3 capsules are tiny and great. I'll repurchase

    Very happy

    I take K2 vitamin in conjunction with vitamin D3. I can feel the difference already. With my other supplements I am no longer lethargic, have lots of energy and feel great. Thank you 😊
