Jarrow Formulas L-Tyrosine 500 is utilized for the synthesis of catecholamine neurotransmitters, such as norepinephrine, epinephrine and dopamine of which the natural production decreases when being on a fat loss diet. In general, tyrosine increases arousal, focus and vitality when the body is under chronic or extreme stress.
Tyrosine is also involved in production of pigmants and cell surface receptors.
Tyrosine promotes robust cognitive function when under stress.
who benefits from using Tyrosine?
Tyrosine has anti-aging benefits for maintaining dopamine production as we grow older, thus improving cognitive and physical performance. It is also useful for those who want a boost in alertness and focus (can replace coffee in the morning) or who are under constant stress and want to maintain healthy hormone levels and mental alacity.

A powerful amino acid with many benefits
Tyrosine is an important precursor to thyroid and adrenocortical hormones as well as to the brain neurotransmitters dopamine, epinephrine and norepinephrine. In lieu of tyrosine intake from dietary sources, phenylalanine is utilized for its biosynthesis along with necessary cofactors iron, vitamin C and niacin. Since tyrosine can be made by the body it is not considered an “essential amino acid,” per se, but it is essential to the body’s proper functioning.
The thyroid hormones triiodothyronine (T3) and thyroxine (T4) are derived from tyrosine. Tyrosine readily passes the blood brain barrier however it competes with other amino acids for entry into the brain.
Tyrosine plays an important role in cell signaling by regulating many cellular processes via tyrosine kinase receptors (including sensitivity to insulin). Tyrosine is also the precursor to the pigment melanin, which is used by the body in UV radiation protection. There is also some recent evidence that suggests melanin may act as a powerful chelating agent in the body helping sequester toxic heavy metals.
Tyrosine content varies greatly in foods. In general, meats contain higher concentrations than vegetables or grains, with wheat germ being the exception to that rule. As a precursor for excitatory neurotransmitters, tyrosine is an important reserve in the body’s response to stressful conditions.
In studies performed at MIT, animals given extra tyrosine were better able to control stress and avoid depression; human trials with soldiers undergoing intense physical training bolstered these results.
Tyrosine and mood
Sadness and discouragement are natural responses to disappointment or loss. Nevertheless, in our modern society mood is often out of kilter due to diet and lifestyle imbalances.It is common for depressed people to have diets inadequate in vitamins, minerals and protein while being high in refined carbohydrates. Intake of excessive caffeine (about five cups of coffee) can also be associated with mood swings.
Inadequate protein intake, excessive stimulant intake or chronic stress can not only lead to reduced levels of dietary tyrosine but also to depressed levels of tyrosine-dependent hormones and neurotransmitters. Depressed individuals may test positive for MHPG (3-methyl-4 hydroxy-phenylglycol), indicative of lowered tyrosine metabolism. Supplemental tyrosine may help restore nutritional balance. Several studies have found tyrosine to be useful during conditions of stress, cold, fatigue, prolonged work and sleep deprivation, with reductions in stress hormone levels, reductions in stress-induced weight loss, and improvements in cognitive and physical performance.
Tyrosine and brain metabolism
As we age, brain dopamine production declines. A marked deficiency of dopamine in the basal ganglia may result in uncoordinated movement, improper reflex responses, stiffness of gait and other motor problems. This may be due to decreased levels of antioxidant enzymes, resulting in toxic hydrogen peroxide accumulation that is produced during normal dopamine metabolism.
Elevated hydrogen peroxide brain levels may then accelerate destruction of the substantia nigra, a brain region in the basal ganglia responsible for dopamine production. Tyrosine may provide nutritional support in the brain’s response to falling dopamine levels.
Aside from assisting in coordination and tissue repair (by aiding growth hormone release), dopamine promotes the “pleasure” response to activities like eating and sex. One hypothesis posits that overeating may be due to poor dopamine production in the brain.
Indications of tyrosine deficiency
Tyrosine deficiency may cause edema, weakness, impaired liver function and loss of muscle or other tissues. Low protein diets may produce marginal deficiency states. • promotes brain metabolism and energy production
• precursor in thyroid hormone production
• influences immune function and sex drive
• may stimulate Growth Hormone release
• enhances cognitive and physical performance during stress

Forget about exercising to lose weight: you can't outrun a bad diet!
Feeling sad and stressed due to COVID-lockdown?
Depression in winter time is quite normal, because we aren't exposed to the vitamin D-generating sunrays, which also enhances immunity levels. Fortunately, we can take vitamin D supplements to combat seasonal depression as well as enhance immunity levels.
Another way to chase sadness away is by celebrating, no matter whether that's Sinterklaas, Winter Solstice, Hanukkah, Christmas or New Year. We will decorate our houses, exchange gifts and overeat , get a bit tipsy and enjoy ourselves.
This year is different: restaurants, shops and even gyms need to close down and we are not allowed to gather together in groups. Lack of entertainment, retail therapy and exercise will make it much more difficult to overcome feelings of depression.
It gets worse when you are among those who work in the tourism or entertainment industry and have lost your job as well as most of your income.
For now it is probably best to just accept the current state of affairs and try to console yourself with non-edible goods, such as nice music with a good book, entertaining movie, and aromatherapy (perfume/room fragrances).
And, weather permitting, put on your walking shoes and go for a long walk in the forests or local park.
But perhaps you have been feeling too stressed to enjoy whatever you still can do to relax? Or you were already feeling sad before COVID-19 came along? In that case, DHEA might help.
Skin hunger: why we crave touch
As we are in the midst of the Easter Holiday, we can't help but feel sad. While Mother Nature is showing abundant signs of spring during a period of incredibly sunny weather, we are barely allowed to go outside other than to do what is absolutely necessary. Our gyms have been closed for almost a month now while in some countries, people aren't even allowed to exercise. Not just group exercise, but also to just jump on a bike and go for long rides.
While couples and families get grumpy from living together in a cramped space, others face different problems: they are living without any companion whatsoever. Therefore it's not a miracle how all of a sudden, pet asylums have been able to 'clear out' their list of unwanted pets. Not just because people have more time at hand to walk a dog (just about the only thing some are allowed to do) but also because they crave the ability to touch a living being, for lack of being able to touch another human.
Somehow, just like the sense of smell is overlooked, this also is true for the sense of touch. Only when we lose it, we crave it. This craving also is called 'touch hunger' or 'skin hunger'.
How to love your body?
With all these standards for beauty, it’s easy to plummet into a spiral of body-hating. Don’t succumb to the pressure! Love your body, no matter what!
Body shaming is, sadly, a trend these days. You have songs that hate on the skinny girls because “real women have curves.” Then you have songs about shaming people who don’t happen to have the body type of a Victoria’s Secret model. We all know that no one is perfect, but there are still some people who insist on telling people how they should look, how they should act, what size they should be, what their hair color should look like.
Everyone has the right to love their own body. Whether you’re skinny, fat, tall, short, missing a limb, dark-skinned, pale-skinned, what have you, every single body in the world deserves to be loved. It’s just a shame that so many people insist on hating on their bodies, simply because they don’t conform to the unrealistic standards set by society.
