Reviews

"I have genetic mutations which don’t allow me to process fat properly and I’ve had a chronic vitamin D deficiency while trying to treat with normal fat soluble vitamins which never worked. I have been on Bio-Tech Pharmacal D3-5 5,000 IU (Vitamin D3) since the beginning of the year (2021) and finally have sufficient Vitamin D levels for the first time in over a decade. My PCP now has this brand as a recommendation for patients who struggle with normal Vit D therapies to see if it will help them too. I will never switch brands!"
