My Vit D levels did not increase even though I took my supplements every day. So I decided to head outside and lie in a bit of sun for 20 minutes with sunscreen only on my face and décolletage. Vitamin D levels had sky rocketed to over 80 at next blood test.

My gut absorption is poor so I take Vit D liquid drops. If I am prescribed to take a med or vitamin, I try for liquid or capsules as they dissolve easier than tablets for me.

I take 1000mg of Mcal (calcium) + 1000U of VitD /day. Worked for me.

Hi uk here get some sun on your arms that is were you get vit D from
It pretty cool here but sit in sun later i hope a
Elbows on chair arms out thats the best wsy to bust your vit D

Being in the sun does help. I live in New England and my D level is always a lot lower in the winter months..
I read the book “The whole body approach to Osteoporosis “ by Dr McCormick. It is very interesting.. Even had an appointment with him.
So many other minerals help to absorb vitamin D.
Most medical doctors don’t really get to involved in supplements and vitamins, they want us to get most from a healthy diet and exercise. Of course everyone is different when it comes to how our body reacts to nutrition.
