Vitamin D


Studies clearly show that vitamin D is a key nutrient which affects the immune response and has been shown in multiple studies to possess or stimulate anti-viral properties. Assessing vitamin D status and maintaining optimal serum levels should be considered in all but particularly ageing adults and children. Vit D supplementation to achieve normal levels along with micronutrients should be regarded as one of the essential factors which improve health overall and also supports our fight against infectious diseases.⠀If you have SNPs on your vitamin D genes like I do then you will need to supplement all year round. And you may need a higher dose to achieve optimum levels.


Vitamins do not work in isolation; Vitamin K2 works synergistically with Vitamin D and Vitamin A supplementation alongside Vitamin D3 avoids unbalanced excess or artificial deficiency of either vitamin.⠀

This @nutrigold.co.uk vitamin D3, A&K supplement can be taken long-term. If taking other supplements containing Vitamin D then check your total daily intake – if greater than 5000iu daily (125ug) for more than four months then have your Vitamin D levels checked – optimal blood levels for Vitamin D3 are 100-150nmol per litre. I’m just about getting to 100 whereas my husband who does not have SNPS on his vit d genes easily gets there with the same dosage as me!
