Is L-theanineis the predominant amino acid in tea leaves and constitutes up to 50% of the total amino acids in the plant. The amino acid makes up 1-2% of the dry weight of green tea leaves (Montvale, 2008).

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??
