L-Lysine

Buy L-Lysine: an essential amino acid in tablets, capsules and powder

L-Lysine is an essential amino acid, which means that your body cannot produce it itself and that you must obtain it through food or supplementation. L-Lysine is a building block of proteins and is found mainly in animal products, legumes and quinoa. In our range you will find L-Lysine supplements from reputable brands in tablets, capsules and powder, in different dosages, so that you can choose the variant that suits your preference.

What is L-Lysine?

L-Lysine is one of the nine essential amino acids that the human body cannot produce itself. Amino acids are the building blocks of proteins. L-Lysine for supplementation is often obtained through fermentation from plant sources such as non-genetically modified corn.

What contains L-Lysine?

L-Lysine occurs naturally in high-protein foods. Animal sources such as meat, fish, eggs and dairy products generally contain the highest concentrations of L-Lysine and are therefore the main source for most people. Plant sources such as legumes, quinoa, pumpkin seeds and seitan also contain L-Lysine, but in lower amounts. Legumes and quinoa are relatively good plant sources.

Production method and purity

Not all L-Lysine supplements are the same. They differ in production method, the purity of the raw material used and the possible presence of fillers or additives. In addition to the dosage per tablet, also pay attention to the production method and purity.

Recommended dosage of L-Lysine

No official recommended daily amount has been established for L-Lysine. The dosage varies per product and is stated on the packaging. Always follow the recommended dosage on the packaging of the supplement you use. If in doubt, it is wise to ask advice from a doctor or dietitian.

When do you take L-Lysine?

L-Lysine can be taken both on an empty stomach and with a meal, depending on personal preference and sensitivity. Some people take it 30 to 60 minutes before a meal, while others combine it with food because that can be easier on the stomach. L-Lysine can be combined with other amino acids or nutrients such as vitamin C. However, note that L-Lysine and L-Arginine are competing amino acids that are absorbed through the same transport mechanisms, so it is better not to take them at the same time.

L-Lysine in a plant-based diet

Most plant-based protein sources contain relatively little L-Lysine compared to animal products, with the exception of legumes and quinoa. Many L-Lysine supplements are vegan; check this on the product label.

Possible side effects of L-Lysine

L-Lysine is generally well tolerated when used at the recommended dosage. At high dosages, mild digestive issues may occur in some people, such as bloating or nausea. In rare cases, prolonged excessive use can lead to a disruption of the balance between different amino acids in the body. People with kidney disease should be careful with a high intake of amino acids and we recommend consulting a doctor beforehand. It is also wise to consult a doctor during pregnancy and breastfeeding before starting L-Lysine supplementation, because there is insufficient research available on safety in those situations.

Comparing L-Lysine supplements: what to look for?

When choosing an L-Lysine supplement, there are a number of practical things to pay attention to. Firstly, the dosage per tablet, capsule or serving of powder. Secondly, the production method and purity, for example L-Lysine obtained through plant fermentation. Thirdly, the price per daily serving, which can vary greatly depending on the package size and brand. In our range you will find L-Lysine supplements from brands such as Vit4ever, LUTO Supplements and NOW Foods, in tablets, capsules and powder, in different dosages and package sizes.
