‘Tis the season …. to be taking vitamin D

Due to the latitude at which we live in the UK from September until March we are unlikely to get sufficient UV rays from the sun for our bodies to make vitamin D. Vitamin D plays a vital role in the health of the cardiovascular system, immune system, bone health, blood sugar control and brain health. Dietary sources of vitamin D include butter, eggs and oily fish, as well as fortified foods such as some soya milks. However, it may not be easy to eat enough of these foods to maintain optimum levels of vitamin D through the winter. Hence many health professionals, including doctors, recommend vitamin D supplements.

There are a few things to take into account when choosing vitamin D supplements. Firstly, look for Vitamin D3 rather than D2 as it is more bioactive. It is also important to ensure you have optimal levels of vitamin K2 if supplementing with D3 as they work together, particularly in the utilisation of calcium by the bones. Vitamin K2 is found in fermented vegetables such as sauerkraut and natto, and is also available as a supplement.
