Many people have reported lighter sleep patterns when they reach middle age. Scientists have hypothesized that the cells within the pineal gland decrease with age, creating a shortage of melatonin. Maximum levels are found before puberty, from then on steadily declining throughout adulthood. Melatonin also traps, deactivates and destroys free radicals, becoming a powerful anti-oxidant. Whereas vitamin C, E and beta carotene perform similar functions in specific parts of certain cells, melatonin has been known to permeate any cell in the body.
Free radicals are the major cause of aging and age related diseases.
Melatonin levels are not well tested by blood or saliva analysis. Although not all doctors are so conservative, melatonin is usually considered for the anti-oxidant effects in people 60 or over, using low doses, unless difficulty getting to sleep is encountered, in which case the dosage may be as high as 10 mgs. Over dosage causes morning drowsiness. Sublingual sprays work best and quickest. Some melatonin sensitive people may experience daytime drowsiness with the administration of oral melatonin.
