I have been informed that our bodies do not absorb Vit D in the tablet form? Do you offer liquid drops?

That is incorrect though some individuals might have better absorption with different forms based on their digestive system. I actually do better with the tablet form. My lab numbers don't go up as much when I do liquid or gel base but do with tablets. I actually started feeling better almost immediately after switching from a gel cap to these.

The only brand I buy! My functional medicine Dr recommended this brand and every time my lab results come back now my D levels are great! I had a bone density test done and Dr said “I don’t know what you’re doing but keep it up!!”
