I dont know if it can be for the malic acid
Shit it better not be I was about to start taking that for 6 days for the liver flush, apple juice has lots of sugar and apple cider vineagar makes me want to kill myself, it's not easy to find malic acid locally either. I'm having tooth decay as it is. The worst gum and teeth side effects that I had from pfs are luckily behind me like thinning demineralizing see-thru cracking teeth that look like they were break from k2 deficiency causing low tooth calcium but I was drinking soda and chewing old fashioned bubble gum this year so I'm paying the price with black tar like tooth decay in at least 3 teeth and its forcing my gums to ride up, the harder I brush the worse it gets.
It's true drinking enough water helps it makes your saliva less thick and less likely to house the growth of bacteria bad for your teeth. I need to learn more about my mouth, the natural mouthwashes aren't strong enough and the antibacterial ones make you worse off in the long run.
