Melatonin is released in the dark, during sleep. The pineal gland has been implicated in a number of disorders including cancer, sexual dysfunction, hypertension, epilepsy, Pagetâs diseaseâ¦ The pineal gland calcifies with age and melatonin production correspondingly decreases.
In fact, the calcified parts of the pineal gland (hydroxyapatite crystals) contain the highest fluoride concentrations in the human body (up to 21,000 ppm F), higher than either bone or teeth. (Luke 1997; 2001).
