Why buy it at HSN?

Discover the peculiarities that make our amino acid a unique food supplement.

Concentration

L-theanine is an amino acid that is naturally present in tea, especially black tea, but its concentrations are low, in fact most studies use minimum doses of 100mg, this dose is approximately 4 times higher than what we can find naturally in a cup of black tea.

L-theanine by HSN product provides a high dose of the amino acid in its purest form in convenient capsules, no less than 250mg per capsule.

Suitable for vegans

L-theanine, being an amino acid found in tea leaves, is naturally vegan.

However, have you noticed that many L-theanine supplements are not?

This is because companies use gelatine as a glazing agent in the manufacture of capsules. Gelatine is derived from livestock and is therefore not vegetarian.

Our capsules are made from a vegetable polymer, making the product suitable for vegetarians and vegans.

Which products L-theanine 250mg be combined with?

You can combine it with other products from the EssentialSeries range such as GABA, or with the L-glycine of the RawSeries range.

We have created based on caffeine+theanine specifically designed for you! It's called smart caffeine why not check it out??

  • More than fulfills its function

    Gloria 09/09/2025

    I am very happy with this supplement. From the first days I noticed a feeling of calm without drowsiness, something that helps me a lot to disconnect after intense days. I sleep more soundly and wake up rested, without a feeling of heaviness. It has also helped me to be more focused and less anxious during the day. Without a doubt, a supplement that I will repeat.

  • I bought it months ago and it still lasts.

    Mohammed 14/08/2025

    Apart from lasting a lot of months, it is noticeable at the moment and you only need 1 a day. Of course, after a few days it does not have such an effect and becomes something long term, lowering cortisol, anxiety and hyperactivity. I recommend taking it with caffeine, citicoline, tyrosine or some other stimulant for demanding tasks.
