    What is L-leucine powder?

    L-Leucine powder by RawSeries is a vegan food supplement in powder form, based on L-leucine from vegetable fermentation.

    L-leucine is a proteinogenic amino acid, one of the conformational units of protein. It belongs to the group of branched-chain amino acids (BCAAs), and to the group of essential amino acids (EAAs), hence its indispensable condition for dietary intake.

    L-Leucine by RawSeries is an amino acid from plant sources, derived from fermentation processes. It is a supplement 100% suitable for vegetarian and vegan diets.

    Why buy Leucine at HSN?

    Powder format. More versatile

    L-Leucine is an amino acid normally used in gram dosages, so many people find the RAW format more convenient.

    Not you? L-Leucine 500mg is also available in vegetable capsules.

    Vegan dieters use L-Leucine in combination with foods low in Leucine to increase the Leucine content in food, and the powder form is more versatile.

    Due to its total atomisation with a small particle size, it is easier to distribute homogeneously in a solution. It doesn't form lumps and does not settle after immediate mixing.

    Vegetable fermentation

    Amino acids have traditionally been obtained from animal sources (such as feathers, beaks, and hair); in fact, the most widespread source of leucine is human hair.

    At HSN we avoid these sources of amino acids as they are not vegan choices, and we believe that the highest quality food supplements should be accessible to everyone.

    Vegetable fermentation techniques emerged a decade ago on the Asian continent, from cutting-edge biotech innovation companies. They developed a pure, safe and efficient extraction process.

    At HSN we use this same technique, ensuring that the amino acid is of vegetable origin and therefore suitable for vegans.

    How does Leucine taste?

    Leucine has an intense bitter taste.

    L-LEUCINE POWDER

    A critical customer says:

    Imbebible

    Deborah | 08/04/2025

    Although it is true that it dissolves well, it has a strong smell from the start, but the worst thing is the taste, it tastes pretty bad and I can't even finish it.

    Aunque es cierto que se disuelve bien, ya de entrada tiene un olor fuerte pero lo peor es el sabor, sabe bastante mal y no me lo puedo ni terminar.

    Ensure minimum Leucine

    If I take a not very large dose of protein, which due to its composition does not reach 2.5 grams of leucine in that intake, I supplement with this Leucine product to ensure that there is no lack of leucine in that intake due to the important function that this amino acid has.

    Si tomo una dosis no muy grande proteína, que por su composición no llega a los 2,5 gramos de leucina en esa toma, complemento con este producto de Leucina para asegurarme que no falte leucina en esa ingesta por la función tan importante que tiene este aminoácido.

    Good price

    I have been taking it for a short time and I have not noticed any effects yet. I take it with meals to increase the protein value. The taste of the powder is not pleasant but it is not taken for taste.

    Lo llevo poco tiempo y aun no noto efectos. Lo tomo con las comidas para incrementar el valor de las proteínas. El sabor del polvo no es nada agradable pero no se toma por sabor.

    Good

    I bought it to get the most out of it in protein shakes. The taste is a little bitter, but mixed with the protein is not noticeable.

    La compré para aprovechar lo máximo en los batidos de proteínas. El sabor es un poquito amargo,pero mezclado con la proteína no se nota .
