https://rumble.com/v4cr2j9-flouride-poisoning.html Do some research and check your water and your toothpaste! The pineal gland is a small, soybean-sized gland located in the brain. The pineal gland synthesizes melatonin, a hormone that regulates the sleep-wake cycle. How much this affects your sleep depends on the extent to which your pineal gland is calcified. As the pineal gland calcifies further, poor sleep eventually turns to primary insomnia. People who try to decalcify the pineal gland will often stop consuming fluoridated water and flouride toothpaste.
