Nutrition Facts

Daily Intake: 2 tablets (2,000 mg)

※ % Nutrient Value: The ratio of the daily nutrient value.

Main Ingredient

① Theanine: Increases GABA production and reduces glutamate through serotonin increase

- Theanine is a functional ingredient for anxiety relief and can help by reducing glutamate, an excitatory neurotransmitter.

- It crosses the blood-brain barrier within 1 hour of ingestion and maintains its concentration for 5 hours.

- Related Mechanisms

 1) Increased GABA synthesis → decreased norepinephrine → reduced glutamate

 2) Increased serotonin → decreased norepinephrine in the nucleus accumbens → reduced glutamate

 3) Interferes with glutamate receptor binding by glutamine → reduced glutamate

 4) Other: Decreases corticotropin and corticotropin-releasing factor → induces a reduction in cortisol and serotonin

- Daily intake: 200-250mg

- Composition: 250mg (maximum daily intake)

▷ Origin: India

② Magnesium: GABA action activation, serotonin signaling promotion, glutamate reduction, and other neurological health-related mechanisms

- Magnesium plays a key role in stress response regulation and neurotransmission inhibition, promoting neurological health through various mechanisms.

- Related Mechanisms (https://www.mdpi.com/2072-6643/12/12/3672)

 1) Enhancement of GABA action

 2) Direct promotion of serotoninergic signaling in cells

 3) Assists tryptophan hydroxylase, which is involved in serotonin synthesis

 4) Blocks glutamate receptors

 5) Decreases ACTH → reduces cortisol

 6) Promotes the expression of brain-derived neurotrophic factor (BDNF)

- Daily intake: 94.5mg - 315mg

- Composition: 315mg (100%)

▷ Origin: Japan

③ Vitamin B6: Supports GABA and serotonin production when taken in high doses alone or with magnesium

- Vitamin B6 has been shown in human clinical studies to alleviate anxiety and depression when taken in high doses alone or in combination with magnesium.

- Related Mechanisms (https://www.liebertpub.com/doi/abs/10.1089/152460900318623)

 1) Produces GABA and serotonin, influencing selective regulation
2) Activated when taken with magnesium

- Daily intake: 0.45mg - 67mg

- Composition: 1.5mg (100%)

▷ Origin: DSM, Germany

④ Vitamin C: Activation of GABA receptors and reduction of glutamate

- Vitamin C is commonly consumed for cortisol (stress) regulation, but research has also been conducted on its role in GABA/glutamate regulation as a standalone ingredient.

- Related Mechanisms (https://www.mdpi.com/2072-6643/9/7/659)

 1) Activation of GABA receptors

 2) Prevents nerve stimulation by interfering with glutamate receptor (NMDA) binding

 3) Other: Adrenal function regulation (regulation of catecholamine and cortisol synthesis, adrenal inhibitory effect)

- Daily intake: 30mg - 1000mg

- Composition: 30mg (30%)

▷ Origin: UK

ⓢ Zinc: Acts on the GABA, serotonin, and glutamate systems

- Zinc is insufficient in clinical studies, but low zinc levels have been observed in anxiety patients, and its related mechanisms are well known.

- Related Mechanisms (https://pubmed.ncbi.nlm.nih.gov/37364014/)

 1) Reduces anxiety through actions on the GABA, serotonin, and glutamate systems

- Composition: 8.5mg (100%)

▷ Origin: USA

⑥ Other Sub-ingredients: Ingredients that may assist in the action of theanine

- Black Garlic Extract 100mg (SAC 1mg): Reduces cortisol, normalizes serotonin/dopamine/norepinephrine levels, prevents dopamine depletion

 ▷ Origin: Netherlands, contains 1% SAC

- GABA (Other Processed Products): Helps increase GABA synthesis from theanine

 ▷ Origin: South Korea

- St. John's Wort (Western horseradish): Helps increase serotonin levels

 ▷ Origin: Spain

- Tryptophan: Precursor material for serotonin synthesis

 ▷ Origin: China

- Choline: Precursor of phosphatidylcholine, increases phospholipids and synapses in the brain

 ▷ Origin: Italy

Selling Point

① Theanine + 5 Vitamins/Minerals + SAC 1mg: Relieves chronic anxiety in modern people and enhances concentration

- This product contains synergistic ingredients that can enhance the mechanism of the functional ingredient, theanine, for the relief of anxiety and depression, such as [GABA production and serotonin increase].

- Theanine increases the levels of GABA (an inhibitory neurotransmitter) and serotonin, reducing glutamate to alleviate depression/anxiety.

- The effect of theanine is similar to that of benzodiazepine antidepressants and serotonin reuptake inhibitors.

※ The maximum daily intake of 250MG is combined, allowing for easy intake of theanine equivalent to 10 cups of red tea in just 2 tablets.

② Magnesium 100% + Vitamin B6 100%: Key nutrients for stress response regulation, clinically proven in combination

- Magnesium activates GABA action, promotes serotonin signaling, and enhances the synergistic effect of theanine, while also promoting adrenal regulation and BDNF expression.

- Zinc, when taken with magnesium, has been clinically proven to alleviate anxiety and depression.

※ Combining 100% of the daily intake to support theanine and maximize the effects of magnesium/zinc.

③ Vitamin C 30% + Zinc 100%: Controls cortisol and GABA/glutamate simultaneously to prevent anxiety

- Vitamin C helps regulate adrenal function affected by stress, while also activating GABA and reducing glutamate.

- Zinc, which is often observed to be significantly low in anxiety/depression patients, acts on the GABA, serotonin, and glutamate systems to provide support.

※ Combining Vitamin C 30% and Zinc 100% enhances the synergistic effect.

④ SAC 1mg + 4 Other Brain Health Ingredients: Restores neural balance and prevents dopamine depletion

- SAC (a phytochemical found in black garlic) provides super antioxidant and neuroprotective effects.

- GABA, St. John's Wort, and Tryptophan help increase GABA and serotonin levels.

- Choline, a precursor to phosphatidylcholine, promotes brain health by increasing phospholipids and synapses in the brain.
