Was sceptical

Hi well as the title say was sceptical,but was , unfounded.as all things claiming to be as a one job fix all .So to be honest,I have found they do make a difference,then most K vitamins.have felt more alive if that's the correct phrase,and the size is ok to swallow,have been takyfor about month now ,and happy with the results,so far .So yes will purchase again ,The quality is and looks good ,the compounds and the amounts are just correct for me ,,any ways they work for me

quality product

came across the use of Vit K for purpora, reddish, purplish spots similar to bruising occurring on lower legs and forearms after hearing a cardiologist discuss the association and positive effect. In searching for a Vit K supplement, found Arthur Andrew Medical- KD Ultra containing a full spectrum Vit K2 with MK-4,6,7 along with Vit D3 which I understand together help for better absorption. It appears to be working for us. Highly recommend

I maintained decent levels of blood vitamin D while using this product. I find its quality and ingredients to be decent, and the dosage is proper. In summary, it was effective for my goals.

KD3

I love this product. I’m a stone formers and unable to take calcium. I’m able to use this with no concern about the ingredients or dosage. The cost was important for me, as well. It is affordable.

Seems like a good product, no fillers (I don't mind the rice maltodextrin) and there's 3 types of vitamin k2 in what seem sufficient amounts. I just started taking it and cannot give an opinion on its effectivity yet but so far no negative effects.
