My doctor told me to drink tonic water to add some quinine to my diet for my leg cramps. After reading the sugar content on the label of all the tonic waters, I wondered why he would suggest tonic water. Then, I remembered I had bought the Quinine tincture during COVID at the recommendation of a friend, but never used it. So, I put a dropper full in some water daily and over the next few days, I noticed my leg cramps had gotten better. When I ran out, I bought the pills instead, but recently bought the tincture again. Someone had posted here that they thought the tincture worked better than the pills and I have to agree. I take so many supplements already, it's nice to take something that's going to go down easy. I would definitely recommend it for leg cramps. I know when I've missed a few days, they return. I now put a daily reminder on my phone to "take your quinine!" Thanks for a great product.
