Hi Paulette, I did see significant improvements in my overall mood and helped with allergic/immune reaction - leaky gut and mold exposure. ALOT !!! it is recommended for people with asthma / allergic attacks along with Ca/Mg to balance the body reaction.
Onwards has a point with increased Ca absorbtion by D3 but maybe you can take Mg oil to balance?
Anyway if you took it in the future It is better to take D3 morning or noon not evening.
Vit K2 helps better distribution of calcium in the body - for example send it to the bones and teeth and not in the arteries as it happens when you lack K2.
The funny thing is your body is able to produce K2 by good gut flora but many AF sufferers have disturbed flora so supplementing from outside body is the only way until you reestablish the balance down there. Please check online for more info ;)
Good luck PS: When my liver was/is congested by too many toxins I have yellowish BM. But remember ANY toxins no matter if from infections or from the supplements to cure an infections...or cooper detox...
