I ordered this product for my mom. She’s 75 and has been suffering tremendously from joint pain and very worrying high blood pressure for the last two years of her life. She has taken a myriad of supplements but nothing has really worked, until I sent her this vitamin D3 and asked her to take a therapeutic dose. The day after her first dose she contacted me to say that she had slept very well at last and that she woke up for the first time in years without feeling any body pains at all. She also noted her blood pressure at optimal levels, which was a huge bonus to her health problems! Great product! We’re delighted! Thank you!
