What is Lysine?
Lysine is an essential amino acid that our body cannot produce itself. It plays a crucial role in the production of proteins, enzymes, and hormones, and is important for the maintenance of skin and the immune system.
Why should you have Lysine measured/tested?
Testing Lysine is useful for people suffering from Rosacea, a chronic skin condition that causes redness and pimples on the face. Lysine may help reduce the symptoms of Rosacea through its role in skin health and immune function.
What does it indicate?
The Lysine test measures the amount of Lysine in the blood. The results can help identify nutritional deficiencies or assess whether Lysine supplementation might be beneficial for the management of Rosacea.
What does a high Lysine level mean?
A high Lysine level may indicate sufficient intake of the amino acid through diet or supplements. It is rarely a sign of problems, but it is important not to consume too much Lysine, as this can lead to side effects such as stomach pain or diarrhea.
What does a low Lysine level mean?
A low Lysine level may indicate a deficiency, which can contribute to skin problems, reduced immune function, and increased susceptibility to infections. In the case of Rosacea, a deficiency can worsen symptoms.
