Understanding L-Theanine

L-theanine is an amino acid predominantly found in the leaves of Camellia sinensis—the tea plant. Unlike many amino acids that serve as protein building blocks, L-theanine is classified as a non-protein amino acid, and it's one of the key compounds that gives green tea its characteristic flavour and calming reputation.
When consumed, L-theanine can cross the blood-brain barrier, which is relatively uncommon for amino acids. This bioavailability is what makes L-theanine particularly interesting to researchers and supplement formulators alike.

Why Purity Matters

Not all L-theanine supplements are created equal. Lower-grade formulations may contain D-theanine (a less desirable form) or other impurities that dilute the active compound. Herba® L-Theanine exceeds 99% purity, meaning each 250mg capsule delivers pharmaceutical-grade L-theanine with minimal inactive compounds.

The 250mg Dosage

Our formulation provides 250mg of L-theanine per capsule—a dosage commonly used in clinical research. This amount allows for straightforward daily supplementation while providing meaningful quantities of the amino acid in a single serving.
With 240 capsules per bottle and a recommended intake of one capsule per day, Herba® L-Theanine offers exceptional value as an 8-month supply. This eliminates the need for frequent reordering and ensures consistency in your daily routine.

Clean Formulation Standards

Herba Health has formulated this supplement with simplicity in mind. The capsule shell consists of hypromellose (a plant-derived material suitable for vegans), while cellulose serves as the only additional non-medicinal ingredient.

We've specifically excluded magnesium stearate, a flow agent commonly used in supplement manufacturing. The formula is also free from gluten, dairy, soy, eggs, and sugar—making it accessible to those with common dietary restrictions or sensitivities.

Made in Canada

Herba® L-Theanine is manufactured in Canada following cGMP (current Good Manufacturing Practice) standards. This production framework ensures consistent quality control from raw ingredient verification through final packaging.

The product has received a Natural Product Number (NPN) from Health Canada, which requires evidence of safety, efficacy, and quality before a supplement can be legally sold in Canada. This licensing process provides an additional layer of regulatory oversight that distinguishes Canadian supplements in the global marketplace.

Q. What is L-theanine and where does it come from?

A. L-theanine is a non-protein amino acid found naturally in tea leaves, particularly green tea (Camellia sinensis). It's one of the compounds responsible for tea's distinctive taste and has been consumed by humans for centuries through traditional tea drinking.

Q. What does ">99% purity" mean?

A. This indicates that more than 99% of the active ingredient in each capsule is pure L-theanine, with less than 1% consisting of other compounds. Higher purity means you're getting more of the actual amino acid per dose, with fewer inactive substances.

Q. Is Herba® L-Theanine vegan-friendly?

A. Yes. The capsule shell is made from hypromellose, a plant-derived material, and the formula contains no animal-derived ingredients. It's suitable for vegan and vegetarian diets.

Q. What allergens is this product free from?

A. Herba® L-Theanine is free from gluten, dairy, soy, eggs, and sugar. It also contains no magnesium stearate.

Q. How long will one bottle last?

A. At the recommended dosage of one capsule per day, a 240-capsule bottle provides an 8-month supply.

Q. What does the NPN number mean?

A. NPN stands for Natural Product Number. It's a license issued by Health Canada after a product has been assessed for safety, efficacy, and quality. The NPN 80143890 confirms that Herba® L-Theanine has met Health Canada's requirements for natural health products.

Q. Can I take L-theanine with other supplements?

A. L-theanine is commonly paired with caffeine (such as coffee) or taken alongside other supplements. However, we recommend consulting with a healthcare practitioner before combining supplements, especially if you have existing health conditions or take medications.

Q. Is third-party testing performed on this product?

A. Yes. Every batch of Herba® L-Theanine undergoes third-party testing to verify safety before release.
