Thanks and I hope your husband was willing to try this.
My wife was deficient but she did not have the pain like I did.
Besides pain relief (which not everyone needs) vitamin D has so many benefits it is not funny including remineralizing bones and preventing many cancers.
If your husband tries this, please please share his results.
Do not be afraid of over dosing. I use 5K IU almost everyday (I forget sometimes). It is almost impossible to overdose. Some people take 10 and 20K IU per day.
And if this blog helps or if you think it might help someone, please resteem :)
Thank you.
