Why Aging People Become Depressed, Fatigued, and Overweight
Normal aging results in a reduction of tryptophan our brain needs to make serotonin. A serotonin deficiency can result in unwanted weight gain, mood swings, and disturbed sleep. Restoring tryptophan is often difficult in aging humans because it is rapidly degraded by pro-inflammatory cytokines. A new pharmaceutical-pure tryptophan has been combined with specific ingredients that prevent its excessive depletion, thus sparing tryptophan for conversion to serotonin in the brain.
