You need to take Vit K with D3....I aim to keep my D level between 60and 80...it is NOT too high...unless your allergic to D.
If you don’t take excess vitamin d, I don’t think you need to take vitamin k supplements.
Were you able to reach 60 ng/ml. Have you noticed differences or benefits?
I take @ 10,000 a day...and generally am around 60....once got it to 100...and I believe I’ve benefitted...one cold, no flu or covid for several years. Plus d3 is a hormone and helps with other health issues.
