Suntheanine L-Theanine 100 mg, N60 - Swanson

What the product is

Swanson Suntheanine L-Theanine 100 mg is a food supplement for people who want to feel calmer without becoming sleepy. L-theanine is an amino acid best known from tea leaves, where it is associated with a clear, settled state of mind.

Key component

• Suntheanine® — a branded form of L-theanine produced for purity and consistency. Not all amino acid supplements are equally standardised, and Suntheanine® is the version most often mentioned in discussions around calm alertness.
• The 100 mg strength in vegetarian capsules is a practical option for those who prefer a moderate amount that can fit easily into a busy schedule.

When people choose it

Its effect is not the same as a sedative. L-theanine is valued because it can help the brain shift away from an overstimulated, "always on" mode while preserving attention. It is often used when a person feels mentally crowded, distracted or internally restless, yet still needs focus.

Swanson L-theanine may suit adults who want a gentler way to ease into a more balanced mental state:

• Before presentations
• During intensive screen-based work
• While travelling
• As part of an evening wind-down
• People who are sensitive to stimulants and want something that encourages relaxation without heaviness

Important notes

As with any supplement affecting mood or the nervous system, it is wise to use it thoughtfully. If you are pregnant, breastfeeding, taking medication, or managing an ongoing health condition, speak with a healthcare professional before use. If you are looking for a product specifically for persistent sleep problems, strong anxiety or low mood, a more individual approach is important.
