L-Lysine is an essential amino acid, meaning it needs to be consumed through your diet since your body cannot produce it on its own. It plays a crucial role in several bodily functions.

At our online store, you'll find a wide range of amino acids, including premium-quality L-Lysine supplements available in vegan capsules or powder form.

HSN has chosen plant-based fermentation for producing its amino acids. While some brands use animal-derived ingredients, our L-Lysine supplements are 100% plant-based.

Traditionally, amino acids are extracted from animal tissues, which raises ethical concerns for vegetarians and vegans. Our plant-fermented product range offers an ethical, sustainable alternative—at the best price on the market.

HSN is IFS Food-certified, among other credentials, and became the first brand in the sector in Spain with its own factory to achieve this certification in 2021. This ensures you get products with unbeatable quality at a price that’s impossible to match. Our policy is defined as Right Price or Fair Price.

We also follow ‘clean label’ practices, so you know at all times what you are taking and how much you are taking.
