Hi
Just some info. Over the last couple of years I’ve had several vit D tests. Back in 2019 the minimum level was 75, this has recently been reduced to 50. I’m only in the 80’s and will definitely keep taking it. The top end is 200 or 250, huge difference.
This either means they’ve reduced the level based on more people being tested and low levels are showing as average, they just don’t want everyone to show as deficient or there is substantial evidence to show normal starts at 50, which I haven’t found yet. Be interested in any links showing this.
It’s an important nutrient for the hormonal system.
