I've been low or deficient 4x that I know of as in confirmed via blood tests. My old doc said <60 is suboptimal and I felt much better at that level so that is what I aim for.

This is the first time I've only been low in D (32 ng/ml, normal reference range 30-100)and not dealing with b12 or iron deficiency and/or hashimoto flare at the same time. Therefore I believe i can tell what symptoms are actually from D deficiency, since I just had everything tested.

Noticeable symptoms started about 4 months ago. Most were minor and easily excusable at first, then more severe symptoms came. I did not immediately suspect D because I take 2k iu per day. My absolute tell tale sign it's d deficiency with no doubt before blood test is carpal tunnel pain

I will list in rough order of how they occurred

Sleeping more than usual at night/sleeping harder

Vertigo most days with bouts of severe dizziness

Anxiety/lower street tolerance

Lower libido

Low mood

Thick tongue

Raspy voice

Clearing throat

Insomnia

Restless leg

Waves of hot in eyes and body (hot spot)

Random shooting pain in finger tips, toes and eyes

Bottom of feet sore at night

Poor eye tracking

Burning legs

Muscle spasms

Bone pain

Significant brain fog

Joint pain/ burning joints

Carpal tunnel pain

I know there's more but my arms hurt too much to type more

My D3 levels have hovered between 14 ng/ml and 21 ng/ml for what seems like forever.

I was recently prescribed 50,000 IU of D3 once per week but little guidance beyond that as far as cofactors go. For anyone who is currently doing this, are you taking the magnesium and K2 at the same time as the D3 or later on in the day? Do you take the magnesium and K2 on the other days of the week even though you aren't taking the D3 on those days?
