Vitamin D & K – Key Facts

Vitamin D:

  • Vitamin D is a family of fat-soluble, cholesterol-like substances called secosteroids.
  • Most vitamin D is made in the skin through light exposure and only small amounts are obtained from dietary sources (oily fish, meat, dairy products and eggs).
  • It has far reaching benefits including helping to maintain normal bones, teeth, immunity, and muscle function, and also playing a role in cell division.
  • Vitamin D deficiency is linked to an increased risk of infection, allergy, [i] and autoimmunity[ii] to name just a few associated health risks.
  • Some of us also carry variants of the gene which codes for the Vitamin D Receptor (VDR), which can make it harder for vitamin D to bind to it and then carry out its multitude of different actions within cells.[iii]

Vitamin K:

  • Vitamin K exists in two forms:
    • Vitamin K1 (phylloquinone) found in plants, mainly broccoli, spinach, parsley, and cabbage.
    • Vitamin K2 is a family of compounds called menaquinones (MK). There are a number of types ranging from MK-1-MK-14. Vitamin K2 is synthesised by certain gut bacteria and also naturally occurs in foods such as butter, cow liver, chicken, egg yolks, fermented soy bean products and some cheeses.
  • The MK-7 form is rarely found in diets – the best source is a type of Japanese fermented soya product called natto.
  • In comparison to vitamin K1, vitamin K2 MK-7 has a very long half-life, resulting in much more stable blood levels (7- to 8-fold higher), if used over a longer period.[iv]
  • Vitamin K contributes to normal blood clotting. Note that it is not suitable for people taking anti-coagulant medication.
  • It also contributes to the maintenance of normal bones.
  • Vitamin K deficiency is linked to low bone mass density, osteopenia and higher fracture risk.[v],[vi],[vii]
  • Some individuals carry a variant of the gene that produces an enzyme responsible for the conversion of vitamin K to its active form in the body (VKORC1 gene). This may lead to reduced activity of this enzyme,[viii] so some people may have higher needs for vitamin K.

Do you need extra D3 and K2?

Insufficient levels of both nutrients are quite common. In fact, vitamin D deficiency and insufficiency are known to be widespread in the general UK population - up to 25% may be severely deficient.[ix] In the UK sunlight is usually only strong enough to stimulate vitamin D synthesis between 11am to 3pm from April to October. In addition, modern lifestyles mean we often spend a lot of time indoors, use sunscreen or wear clothes which prevent sunlight exposure. Groups at particular risk of deficiency include individuals with dark skin, those who cover skin or use sunscreen when outside, the elderly, obese, and vegetarians and vegans,[x] and those with inflammatory bowel diseases.[xi]

In turn, vitamin K intake is also often insufficient but many of us, including health professionals, may not be aware of it. Low levels of vitamin K are surprisingly prevalent. The daily recommended intake is 75µg, however an American survey revealed that about 50% of Americans consumed less than the recommended amount. The authors of this review further suggested that the optimum level is 90 µg for women and 120 µg for men.[xii]

Suggested Combinations

Our Nutrisorb® D3 & K2 is really easy to take and can be a perfect addition to a more comprehensive nutritional protocol. If you’d like to use it for everyday support and get slightly more of both nutrients, take it together with a good multinutrient, e.g. Methyl Multinutrient, which also contains D3 & K2, alongside all key vitamins and minerals. If you’d like to support a specific area of health, here are some of our top suggestions:
