Melatonin (mel-ah-TONE-in)
N-acetyl-5 methoxytryptamine (AS-e-til me-thok-see-TRIP-ta-meen)
A hormone produced by the pineal
gland that boosts the immune system and helps people with jet lag or insomnia.
Metabolite (meh-TAB-oh-lite)
Any product of metabolism such as an intermediate or an end
product that is excreted.
Methionine (meth-EYE-oh-neen)
A sulfur-containing essential amino
acid that is a precursor to cysteine
and taurine. Methionine may elevate the catecholamine neurotransmitters
via S-adenosyl L-methionine (SAM), which is made from methionine
by ATP and SAM synthetase. Methionine is also a component of
various endorphins. Methionine supplements may be more
cost effective than SAM, since methionine readily crosses the blood-brain barrier (BBB). Methionine supplements should not be taken without also taking
B-6 supplements because this could raise homocysteine levels.
Methylxanthines (METH-ill-ZAN-theens)
Caffeine, theophylline, or theobromine.
