I’ve been taking this specific brand of Iron for at least a year. In the 1st place, I was given it by my holistic doctor from Atlanta, GA. I had to buy a bottle on my own because I was going to run out before my next appointment, and this was cheaper than paying for an extra phone appointment with my doctor. I take this every night, and I can tell if I forget it the next day because my energy level is lower. Plus I tend to be anemic, so this is important for me. It’s hard to take liquid Iron, but the apple cinnamon flavor helps quite a bit.
