Vitamin D3 & K2

This product contains 100µg (4,000i.u.) of vitamin D3 as cholecalciferol from a vegan source, and 100µg of vitamin K2 (MK-7). It is intended for short term use to elevate levels of vitamin D where low levels have been identified with a blood test. Alternatively, it may be taken for two to six months over the winter.
 
Vitamin K2 works synergistically with vitamin D. We need both in adequate amounts to ensure optimum biological activity of both vitamins. Therefore, if supplementing with vitamin D, we need to also include sources of vitamin K2 in our diets, or take a supplement
Those at particular risk of vitamin D deficiency are children (under 5 years), the elderly (65 years +), people who rarely get outdoors (lack of sunshine) and people with dark skin
The source of the vitamin D3 in this supplement is lichen

Please note: This supplement contains 100µg (4000iu) of vitamin D per capsule. If taking other supplements containing vitamin D please check your total daily intake and if it is 125µg (5000iu) or more per day, for more than two to four months, you should have your vitamin D levels checked regularly. An adequate blood level is considered to be above 50 nmol/litre; the scientific literature suggests that a higher level of between 100 to 150 nmol/litre is optimal; levels above 250 nmol/litre are not advised. Please note some laboratories use different units i.e. ng/ml rather than nmol/litre quoted here. In this case the optimal range is 40 to 60 ng/ml
