How It Works
How It Works
L-lysine is an essential amino acid your body cannot produce on its own. It works by supporting protein synthesis and immune cell function, while competing with arginine—an amino acid that certain viruses need to replicate. This dual action helps maintain immune health and supports tissue repair processes.
Who It's For
Adults looking for immune system support, especially those prone to cold sores or HSV infections. Also beneficial for active individuals focused on tissue repair and recovery, or anyone wanting to support collagen formation for healthy skin and joints.
Who It's Not For
Not suitable for children or those with kidney disease without medical supervision. Pregnant or breastfeeding women should consult a healthcare practitioner before use.
About This Product
One tablet of Natural Factors L-Lysine 1000 mg provides 1000 mg of L-lysine as the hydrochloride. Helps in collagen formation.
What is L-lysine?
Amino acids are the units that proteins are assembled from. Nine of them are called essential because the human body has no way to produce them, and lysine is on that list, so it must be supplied by the diet. Meat, fish, dairy and legumes are common food sources.
Key features
- 1000 mg L-lysine (hydrochloride) per tablet
- 120 tablets
- Vegan and non-GMO
- Gluten-free, dairy-free and soy-free
Why a 1000 mg tablet?
Lysine tablets are commonly sold in 500 mg and 1000 mg strengths. The higher strength provides a full gram of this amino acid in one tablet, which means fewer tablets to count out for anyone who wants that amount.
