DESCRIPTION Building block for neurotransmitters Mood support, alertness and focus Free-form amino acid for maximum absorption Amino acids are classified as either essential or non-essential. Essential amino acids cannot be synthesised in the body and must be obtained from the diet, whereas non-essential amino acids, whilst still essential for health, can be synthesised in the body and are therefore not classified as `essential`. Tyrosine is considered a non-essential amino acid because the body can make it from phenylalanine. It is important to brain nutrition because it is a precursor of the neurotransmitters - dopamine, adrenaline and noradrenaline. It also acts as a precursor for certain hormones, including thyroxine and for the major human pigment melanin. As with all LAMBERTS amino acids, LAMBERTS L-Tyrosine is presented in its free-form for maximum absorption. Each capsule provides a full 500mg of L-Tyrosine. DIRECTIONS Take 1 to 4 capsules daily with water or fruit juice,or as directed by a practitioner or pharmacist. An Amino Acid is best taken 1/2 hour before any meal or at bedtime. INGREDIENTS 60 Capsules One Tablet Contains: Contents: L-Tyrosine 500mg Capsule Shell (Gelatin), Silicon Dioxide, Magnesium Stearate, Cellulose.
