Theanine Supplements

Does boosting your mental focus and sharpening your concentration while still relaxing your nervous system seem impossible? Well, Theanine does just that!

Theanine (or L-Theanine) is an amino acid naturally found in green tea. It’s unique in that it promotes relaxation while increasing focus and concentration. In fact, this amino acid is both a natural relaxant and sedative, that does not affect motor skills or make you feel tired and groggy; therefore, it both increases your mental alertness and promotes relaxation. It stimulates the release of neurotransmitters in your brain, including GABA, the brain’s primary inhibitory neurotransmitter. Because it isn’t required by the body, it is considered a nonessential amino acid. These supplements; however, can be extremely useful as natural anxiolytics for mood disorders and chronic stress, as well as to help improve mental function and other cognitive health conditions.

Benefits of Theanine

Who Needs Theanine?

Naturopaths often recommend this nutrient to boost mental alertness, focus, concentration and mood-based symptoms. Some of the most common uses for theanine include; anxiety, cognitive disorders, mood-related disorders, sleep difficulties & insomnia.

Theanine Supplements

Potencies

Theanine supplements are typically recommended in a dosing range of 100–200mg twice daily, but the dose may be higher depending on the condition (400-500 mg daily).

Formats

These supplements are available in a variety of formats, including capsules, liquid gels and tablets. Theanine can be taken either with meals or on an empty stomach.

When supplementing with Theanine for mood disorders, consider taking it with GABA or 5 HTP to increase serotonin boost and help balance stress.

If you’re using this nutrient to support sleep issues or insomnia, consider taking with magnesium to promote better relaxation before bed.

Final Thoughts

These supplements generally come in the form of L-theanine, which is considered the bioavailable form of the amino acid. Supplements are also available in Suntheanine form - a patented theanine made via fermentation that is said to be more potent and faster-acting. Because these supplements are often marketed for mental alertness, be sure to check the label to make sure caffeine has not been added, which would adversely affect anxiety, stress and sleep.
