Hi ATB,
I certainly feel better on it than not. Dose is 3 sprays a day for 3000iu. I had my Vit D tested a few years back in January as every bit of me ached and I felt miserable. It came back as 40 so low and put on Fultium 800iu capsules, the blue dye made my water go green! So went on to tablets 1000iu Vitabiotics I think? Then had investigations for my high calcium levels as PTH and calcium were both high together, and that was the start of another journey. I did a lot of research into Vitamin D, how it is involved with bones kidney etc and many recommended the Better U spray with K2 added to help the Vitamin D go to bones rather than sloshing around in my blood making eggshells. NHS don’t like testing Vitamin D as they say everyone is low in Winter but my endo does test it occasionally although with lockdowns it’s not been done for a while. Last time it was done it was December 2019 and was 68 so an improvement but I am only allowed 1000iu a day and I use it all year round, reason being too much Vitamin D would make my calcium even higher. Some advocate much higher doses but you can go too high, I don’t want to do the large weekly loading doses.
Anyway I had genetic testing done and they say it’s a rare benign condition called FHH, I have a much higher set point before my kidneys start getting rid of excess calcium in the body rather than an adenoma on my parathyroids. My mother died from osteoporosis but her calcium levels were normal.
So for me the Better You one works, the bone pain eased.
Some people take the tablets and K2 separately, I guess it's trial and error but the main thing is that your daughter’s level has improved.
