L-Tyrosine is one of the 22 amino-acids present in the human body, being categorized under the non-essential ones, as a derivative of Phenylalanine. It is used to reduce stress levels, reduce fatigue and increase focus and memory capacity.

This supplement is recommended for people undergoing stress, sleep deprivation, extended periods of emotional distress or prolonged intellectual effort. It claims to regulate hormone levels and neurotransmission, influencing dopamine levels in the human brain.

As with many amino-acid based supplements, L-Tyrosine is considerably sought-after, with people taking comfort in the fact that the substances contained in the product already exist in the human body and by ingesting them they simply increase existing amounts of it, rather than introduce a new element. Also, there is a low number of reported side-effects for this type of supplements, which increases the popularity of such products.

It is due to this popularity that there are numerous manufacturers currently producing and supplying L-Tyrosine. When deciding to try this product, we advise you to research into manufacturers’ reputation and history on the market, as well as inquire about free trials or refund possibilities.

L-Tyrosine Ingredients

L-Tyrosine contains: L-Tyrosine, Gelatin, Silica, Vegetable Magnesium Stearate.

Product Features

The active ingredient in L-Tyrosine is the homonym amino-acid, one of 22 of the ones present in the human body, and one of 14 that are not essential. L-Tyrosine is considered non-essential because it is a derived from Phenylalanine, an essential amino-acid used in supplements as an analgesic and antidepressant.

Unlike its precursor, Tyrosine has little analgesic properties; it has, however, been proved to have antidepressant and regulatory properties. The major downfall of this substance is the fact that it only seems to have effects on people that are already undergoing stressful, tiring or emotionally charged situations; the preventive capacity of this amino-acid is considerably low.

In people that are experiencing the above-mentioned situations, Tyrosine reduces stress hormone levels, weight-loss caused by stressful situations and improves cognitive performance. This is due to the increased dopamine levels that the amino-acid helps synthesize, dopamine being a neurotransmitter with vital importance to the proper functioning of the human brain.

The recommended dose for L-Tyrosine is 100mg daily, while the maximum suggested dose is 150mg. Exceeding this amount can lead to negative side-effects such as nausea and vomiting, joint pains, headaches and heartburn. Excessive amounts of the supplement have also been shown to reduce dopamine levels, leading to the effects opposite to those required.

Conclusion

L-Tyrosine is one of many products available that claim to help people that are undergoing stressful situations; however, it is one of few that only have effect if the person is already experiencing stress, with the advantage that its effects are medically attested.

The large amount of manufacturers points towards the popularity that this product has, fact that supports testimonials regarding the effectiveness of this supplement. It also presents the disadvantage that potential consumers have to conduct their own research into the companies, deciding for themselves who to place their trust with.

Research is advised regarding the product itself as well, seeing as different people have different needs. Before deciding to try L-Tyrosine, it is advised you consult your doctor regarding consumption and dosages.
