Reply To: My husband who is 43 has been taking 100,00 IU of d for a year and his levels have not risen. He works outside for a living so he gets plenty of sunshine. Any suggestions or reasons why someone would not absorb vitamin d?
There are over 40 reasons for having a low response to vitamin D http://is.gd/lowresponse There are only a few reasons for having ZERO response to 100,000 IU of vitamin D3 daily 1) Poor Gut 2) Missing gallbladder and the Vitamin D3 taken in is an oil base 3) Liver functional problem – such as fatty liver disease ( alcoholic or non-alcoholic) 4) Gene problem in the liver If we assume that the problem is #1 or #2 then a different form can be tried Gut Friendly – several brands https://vitamindwiki.com/tiki-index.php?page_id=7255 Topical (on skin)- spray or cream – many brands mouth wash (make it at home – dissolve Bio-Tech 50,000 IU in 1/4 teaspoon of water and let it get around and under tongue and cheeks) Inhaled Vitamin D: http://www.is.gd/Inhale1 Injection – prescription only? ————- If there is a major liver or gene problem then may have to get a prescription for semi-activated vitamin D = Calcidiol, or try to buy a purple herb = SOLANUM GLAUCOPHYLLUM https://vitamindwiki.com/tiki-index.php?page_id=4872
