Scientific Name: L-Theanine
Category: Adaptogens & Stress-Relief Compounds

L-Theanine is an amino acid predominantly found in green tea, recognised for its stress-reducing and relaxing properties. It promotes a calm yet alert state by increasing the levels of GABA, dopamine, and serotonin in the brain. In Neural Calm, L-Theanine works synergistically with other ingredients to enhance mental clarity, reduce stress, and support focus.

Why we use it

We use L-Theanine for its ability to promote relaxation and mental clarity. In Neural Calm, L-Theanine helps to reduce stress, enhance focus, and maintain a calm mental state. This powerful amino acid provides a natural way to support mental well-being without sedation, making it ideal for those seeking a balanced, alert mind.

The science behind it

L-Theanine works by increasing the levels of GABA, dopamine, and serotonin in the brain, neurotransmitters that promote relaxation and improve mood. It also counteracts the stimulating effects of caffeine, promoting a state of calm alertness. Studies have shown that L-Theanine can improve mental clarity, enhance focus, and reduce stress without causing drowsiness, making it a perfect ingredient for promoting mental balance and well-being.

Built Into The Formula

L-Theanine brings a research-backed, non-sedating calming amino acid to Neural Calm, complementing the formula's other botanicals without adding to their sedative effect.

Frequently Asked
Questions

What is L-Theanine?

Branded ingredients are standardised, traceable, and backed by defined active markers. This ensures consistency across batches and greater formulation precision. Instead of relying on generic raw materials, Siha selects registered ingredients with controlled sourcing, documented quality standards, and measurable inclusion levels for transparency.
How does L-Theanine support mental clarity?

A standardised extract contains a defined concentration of active compounds. For example, extracts like Herbagut® or Shoden® are calibrated to specific bioactive markers. This reduces variability and supports consistent formulation design, rather than depending on unpredictable botanical potency.
How does L-Theanine reduce stress?

Some nutrients are sensitive to oxidation or degradation. Oil-based beadlet delivery helps protect these actives from instability before consumption. Delivery science influences how ingredients remain intact, allowing more reliable inclusion and measured absorption within structured daily use.
Can L-Theanine help with anxiety?

Plant-based omega-3 from marine algae provides EPA and DHA directly, without marine intermediaries. This eliminates reliance on fish sources while maintaining defined fatty acid inclusion. It also aligns with vegetarian preferences and supports controlled sourcing standards.
Is L-Theanine safe for daily use?

Botanicals often provide phytochemical complexity, while amino acids contribute structural or metabolic roles within the body. Combining both allows formulations to address multiple pathways simultaneously, supporting balance and alignment rather than focusing on a single compound approach.
