## Features

- Natural 250mg L-Theanine Supplement — 1-a-Day: Each capsule delivers 250mg of L-theanine, a natural nutrient found in green tea that promotes calm and relaxation without sedation. Each pack provides a 30-day supply, offering convenient, daily support for anyone seeking a natural way to support relaxation.
- GABA Supplement Support: L-theanine increases the levels of your relaxing brain chemical GABA. GABA is a neurotransmitter that helps balance and calm neural activity and promotes feelings of calm.
- Fast-Acting L-Theanine Capsules: Our non-sedative L-theanine capsules deliver the equivalent theanine content of 15–20 cups of green tea in a single dose. L-theanine has been shown to increase GABA levels, promoting calm and relaxation within 30 minutes of ingestion.
- Ideal For: L-theanine is ideal for anybody looking to relax and unwind but maintain mental performance and clarity. Suitable for unwinding after work, public speaking, nervous travellers, or anyone looking for a natural relaxant.
- Pure L-Theanine: This is a standalone L-theanine supplement — not combined with lemon balm, which has shown no synergistic benefit. It is also not a synthetic L-theanine such as Suntheanine (Now Foods), Higher Nature, or Jarrow. brain feed ensures the high quality of our extracts and isolates through rigorous testing. Our natural l-theanine supplement is free from unnecessary bulking agents and are manufactured in an FDA-registered facility in the UK under strict GMP, ISO 9001, and ISO 22000 certified conditions, and third-party lab tested.
