Tyrosine – For Thyroid, Adrenals, Stress, Depression, Energy, Weight Loss
L Tyrosine supports the adrenal, thyroid and pituitary glands.
“Effects of L tyrosine supplementation are most apparent during periods of stress.
Tyrosine can reduce the levels of stress hormones and alleviate the presentations of stress such as fatigue and cognitive decline.
The usual dose of L tyrosine is 500 – 1500 mg per day. (Doses above 12,000 mg per day can have negative effects such as paradoxically lowering dopamine levels as well as reducing the absorption of levodopa and other amino acids.)
Since L tyrosine is used to produce neurotransmitters such as dopamine, it can help improve mood and contribute to the management of depression. Even more importantly, tyrosine can help relieve stress.
Tyrosine stimulates the production of neurohormones such as epinephrine and norepinephrine. This results in thermogenesis and the increased muscular activity caused by the increased production of these compounds can help burn stored fat.
The thermogenic effects of L tyrosine can also be due to the increased thyroid hormone synthesis it causes.
Since tyrosine is a precursor used in the production of both triiodothyronine or T3 and thyroxine or T4, it is routinely used in the treatment of hypothyroidism.
The thyroid hormones promote metabolism including the burning of stored fats and the immediate release of energy. Therefore, by improving thyroid functioning, tyrosine can promote weight loss.
For this reason, tyrosine is especially useful in the shedding of weight caused by low production of thyroid hormones.
Although the evidence for the benefits of tyrosine in achieving weight loss is weak, some weight loss experts do claim the amino acid works.
It is especially believed that tyrosine is effective for losing stress-induced weight gain.
There are no standard doses of L tyrosine for achieving weight loss since the use of the amino acid in this regard is an off-label indication. However, a maximal dose of 1500 mg per day can be recommended.
L tyrosine supplements are better taken without food. This is to reduce the amount of other amino acids competing for absorption.
Other supplements may be recommended alongside. These include folic acid, vitamin B6 and copper. These supplements are important for the biosynthesis of neurotransmitters from tyrosine.” Source: progressivehealth.com

L-tyrosine stimulates growth hormone and is involved in adrenal and pituitary function.*
L-tyrosine is also a powerful antioxidant, scavenging and neutralizing free radicals and inhibiting fat oxidation.*L-tyrosine is an amino acid precursor for synthesis of the neurotransmitters norepinephrine and dopamine.* By improving the rate of neurotransmitter synthesis, L-tyrosine stimulates the central nervous system.* It appears to function as an adaptogen by relieving physical symptoms of stress, such as mood swings.* Chronically stressed individuals may not efficiently convert phenylalanine to L-tyrosine, making supplementation with L-tyrosine desirable.*
L-tyrosine also serves as a precursor for the thyroid hormone thyroxine and melanin, the pigment responsible for skin and hair color and protection against harmful ultraviolet rays.*
