Amino acids, the building blocks of proteins, synthesize important molecules in the body, including neurotransmitters, hormones, and pigments. They play a crucial role in developing muscle mass, hair, and all body tissues. Balancing different amino acids is important, as some, like lysine, can block the uptake of others, such as arginine, and vice versa.
Amino Acid Therapy
People often associate amino acids with athletes or bodybuilders, but everyone needs them for mental well-being, digestion, nervous system function, reproductive health, and immune system support. For example, the body uses the amino acid tryptophan to produce serotonin, a neurotransmitter that affects mood.
Healthcare professionals use amino acid therapy to treat various ailments, including mood and mental health disorders, sleep issues, fatigue, cognitive function problems, and ADHD.



Understanding Amino Acid Levels
Your amino acid levels can be either too low or too high. Several factors can cause this imbalance:

Weak digestion, which happens if you don't break down protein properly.
Taking hydrochloric acid inhibitors like Omeprazole.
Consuming a diet low in protein.
Experiencing individual biochemical differences.
Having a deficiency in cofactors, the supplemental nutrients the body needs to utilize amino acids.
Suffering from diseases that impair the body's ability to use certain amino acids effectively.

Performing the Amino Acids Test
You should take the Amino Acids Test on an empty stomach in the morning. You can easily collect all our health tests, including blood tests, at home. To obtain capillary blood, prick a finger and collect the blood on dried blood spot (DBS) paper. Then send the DBS paper to our ISO-certified lab for analysis. We will deliver your results digitally. Children can also perform this test, as long as they can manage a blood test.

The home test was straightforward with easy to follow instructions. The test result was detailed and clear in its presentation. Also had the opportunity to ask questions about the test result.

We looked at a lot of companies offering the same services but made the decision to go forward with get tested because the labs are based here in the UK. The process has been very straight forward.

There are other providers out there, I have tried 3. Gettested was the fastest and the customer service was the best. I even received my test on the day of purchase delivered by a motorbike courier.

Absolutely perfect, results came after few days and finally after a lots of times visited GP, we finally know why my son has eczema - he is allergy to carrot. Thanks a lot.

I found them to be professional and not too long a wait for results. Helpful with any after questions. Will be using them again if need be. I highly recommend them.

Individuals who might benefit from testing their lysine levels include vegetarians and vegans, as lysine is more abundant in animal products. People with protein malabsorption issues, athletes requiring higher protein intake, and those experiencing symptoms like fatigue, hair loss, or slow wound healing could also benefit.

Who would benefit from testing their lysine levels?

<ul>
 <li>Fatigue and lack of energy</li>
 <li>Poor muscle growth or muscle wasting</li>
 <li>Hair loss</li>
 <li>Slow wound healing</li>
 <li>Frequent infections</li>
 <li>Mood changes, such as irritability or depression</li>
</ul>

What are symptoms of low lysine?

Lysine is found in high amounts in meats, poultry, and fish. Dairy products and eggs are also rich sources. For those on plant-based diets, lysine can be obtained from legumes like beans and lentils, soy products, nuts, and seeds, though in smaller quantities than animal sources.

What foods are high in lysine?

Lysine supplementation can aid in muscle repair and growth, support immune system function, and improve calcium absorption, benefiting bone health. It&rsquo;s also used for managing herpes simplex infections due to its antiviral properties. Lysine can be particularly beneficial for individuals with low dietary intake or increased needs.
