PS1000 Ingredients: Tyrosine

Dieters looking for supplements to support healthy weight loss are often bombarded with advertising promising miracle diets and products that simply don’t live up to their absurd hype. The ps1000 diet offers a safe, effective, and scientifically proven alternative, making use of naturally-occurring amino acids and proven herbal supplements to help consumers build muscle mass, increase metabolism, and lose weight. This impressive supplement combines a number of different substances that are perfectly tailored to work in conjunction with each other to build muscle mass, improve exercise capabilities, and encourage healthy weight loss. 


Tyrosine is just one essential component of PS1000, the primary benefits of which pertain more to mental alertness than physical stamina or muscle-building. Consumers considering this supplement can read on to find out about some of the benefits and risks of tyrosine below. 


What is Tyrosine? 

This non-essential amino acid is classified as hydrophobic, although it is more hydrophilic than some amino acids like phenylalanine. It can be synthesized naturally in the body from phenylalanine but is also available in supplemental form. It is best known for assisting in the formation of essential brain chemicals affecting mood and sleep patterns. 


What Foods Naturally Contain Tyrosine? 

There are a variety of foods that contain trace amounts of phenylalanine, which is used by the body to synthesize this important amino acid. Significant sources of phenylalanine include many types of meat, fish, eggs, dairy products, wheat, oats, beans, and nuts. However, not everyone is able to obtain enough tyrosine to meet their bodies’ needs with food alone. 


How Does It Work? 

Tyrosine assists with the creation of several important substances, including dopamine, adrenaline and noradrenaline, melanin, and thyroid hormones. Dopamine is known to regulate reward and pleasure centers within the brain and improve memory and motor skills, while melanin is responsible for producing skin pigmentation and thyroid hormones are responsible for regulating metabolism. Adrenaline and noradrenaline are both responsible for producing fight-or-flight responses in the presence of a perceived threat. 


What are the Implications of This Effect? 

Tyrosine can improve performance during times of stress thanks to its ability to assist in the production of the essential substances described above. While stress can negatively impact reasoning, memory, and attention, tyrosine is known to reduce these negative effects, especially when they are due to cold-induced stress. Two independent studies have shown that tyrosine supplements are even able to reverse mental decline and improve cognitive function. 


What are its Weight Loss Applications? 

When included in weight loss supplements, tyrosine works in conjunction with other essential amino acids and herbal solutions to reduce body fat by nearly 1 kg. It does not, however, improve heart rate, blood pressure, or fat excretion rates, which is why it is most effective at promoting weight loss when combined with other proven substances. As one component of a more comprehensive supplement, however, it is able to improve consumers’ exercise experience, allowing them to burn more fat and lose less weight overall than those who do not take supplements containing tyrosine. 


How is This Supplement Used for Exercise? 

Tyrosine is usually taken in doses of between 500 and 2,000 mg anywhere from half an hour to an hour before exercise. As a supplement, it is available in two forms: as a free-form amino acid or as N-acetyl L-tyrosine, or NALT. NALT has a lower conversion rate within the body, making it less effective than its free-form counterpart for exercise supplementation. 


The primary benefit of tyrosine supplements for exercise is that it preserves mental performance during periods of physical stress. When taken for this use, seven to ten grams are required for every 150 pounds of body weight. Taking higher doses of free-form tyrosine can lead to stomach upset, which is why, when taking a standalone supplement, most consumers take in two separate doses, once an hour before exercise and once a half-hour before exercise. 


Is Tyrosine Safe? 

This amino acid is considered to be safe for consumption by most people when it is taken short-term in doses up to 150 mg/kg per day for three months or less. It is also safe for topical application. However, there is not enough information available regarding its effects on children to suggest its use in supplement form without the supervision of a medical professional. 


Who Should Avoid Tyrosine? 

Women who are pregnant or breastfeeding should not take tyrosine, as there has not been sufficient scientific study performed on its effects on infants. Those with Graves’ disease or hyperthyroidism should also avoid tyrosine supplements, as the extra tyrosine is used by the body to create thyroxine, an essential thyroid hormone. Those who already suffer from high thyroxine levels may find that supplemental levels of tyrosine make their conditions worse. 


Those taking MAOIs, or monoamine oxidase inhibitors, need to be careful about their consumption levels of high-tyramine foods. This is relevant to tyrosine supplementation in that tyramine occurs naturally in foods that are high in tyrosine and phenylalanine, which are converted into tyramine via enzymes produced by various microorganisms. While it has not been proven that tyrosine supplements lead to high tyramine levels in the human body, it’s worth discussing this possibility with a medical professional prior to beginning use of supplements containing tyrosine. 


Are There Any General Side Effects? 

Like all supplements, taking tyrosine does come with the risk of contracting some mild side effects. These include nausea, headaches, heartburn, and fatigue. Patients who experience persistent side effects should seek medical attention prior to continuing their supplement regimens. 


The Take-Away 

Tyrosine is used in dietary supplements to improve mental performance, allowing consumers to focus better and perform better under periods of physical stress. The use of these supplements has been proven safe for most consumers, though it does have the potential to interact with certain medications. Anecdotal evidence regarding alternative uses of supplemental tyrosine requires further scientific evidence, though, so consumers looking to increase physical stamina and lose weight should take supplements that also contain amino acids and substances that are proven to impart physical benefits in addition to tyrosine.
