And I feel better than I have in a long time. I would highly recommend trying it out for a month if you feel groggy or unmotivated to exercise.
I got the gummies because I hate pills, and I have to be careful not to eat two doses if I forget lol they are so good.
In regards to the Vit K being needed to prevent some kind of calcification of Vit D,
As long as some one isn't taking mega doses* (50k+ units) daily then there is very little risk of calcification of Vit D. *mega doses of Vit D are to be taken once or twice weekly; not daily.
Depending on the person prescribing or suggesting vitamin regiment, they are usualy tailored to ones specific lifestyle, age, etc. That would explain why some people get told to take multiple things together and some don't.
TL;DR: Fat-Soluble Vitamins such as D and K are absorbed into the body and "stick around" for a while. As long as there is no daily mega dosing going on then the risk of calcification of any vitamin should be low but absolutely can happen if taken incorrectly.
Is 5000 units D3 daily a "mega" dosis?
No. I would not personally consider 5,000 units of Vitamin D a 'mega dose'. A mega dose is something along the lines of 25,000 units to 50,000 units and beyond.
Please note I am not a medical professional.
I have taken 50,000 units of Vit D before as a medical treatment to correct low Vitamin D levels confirmed by bloodwork. I was prescribed it by a Medical Doctor for my specific situation temporarily once a week for 6 months.
Ok, thanks.
