I bought these vitamins to try out for myself, I wanted to do a test run as I’ve never tried a liquid vitamin before in my 54 years. I cracked it open, tried it out put it in the fridge per the directions. Next thing I know….my kids and grandkids (we all live together) are taking shots every morning! Imma need to replenish, and I wish I could buy in bulk! Everybody is energized and feeling great!
