Swanson L-Tyrosine provides free-form L-Tyrosine – a non-essential amino acid that acts as a metabolic precursor to dopamine, norepinephrine, epinephrine (adrenaline) and the thyroid hormones T3 and T4.
Tyrosine supports mental alertness, focus, and working memory—especially during times of stress, sleep deprivation, or extreme physical exertion. It may also support mood and thyroid health.
Take 1-2 capsules (500 mg-1 g) daily on an empty stomach, ideally in the morning or before demanding cognitive or physical tasks. 100 capsules per bottle.
