Supports Deep Sleep Quality

GABA (gamma-aminobutyric acid) is a naturally occurring amino acid that functions as an inhibitory neurotransmitter. Clinical studies show that 100mg GABA increases deep sleep time by 2.2% compared to placebo. Deep sleep is essential for physical restoration and feeling refreshed upon waking.

Promotes Refreshed Awakening

Beyond sleep depth, GABA supports how you feel when you wake up. Research shows a 20.8mm improvement on a 10cm subjective scale for morning mood quality. This helps you start the day feeling more refreshed and ready for daily activities.

Understanding Sleep Quality

Human sleep cycles between deep and shallow phases throughout the night, gradually becoming lighter before waking.

Quality sleep means achieving sufficient deep sleep phases and waking up feeling refreshed. Modern lifestyles often interfere with achieving optimal sleep quality, making support through ingredients like GABA valuable for many people.

How GABA Supports Sleep

GABA (Gamma-Aminobutyric Acid) is an amino acid found naturally in plants, animals, and our own bodies.

As an inhibitory neurotransmitter, GABA helps calm neural activity and promotes relaxation. Research shows GABA supports both the depth of sleep and the quality of awakening, helping you feel more refreshed in the morning.

Clinical Evidence for GABA 100mg

In a controlled study with 10 healthy adults (average age 37.7 years) who had sleep concerns:

GABA 100mg group: 2.2% increase in deep sleep time
Control group: 3.3% decrease in deep sleep time
Morning mood improved by 20.8mm vs 2.0mm decrease

Deep Sleep Time Clinical Data—Clinical research demonstrates that 100mg GABA supplementation increases deep sleep time by 2.2% compared to a 3.3% decrease without GABA. Study conducted with 10 healthy adults over 7 days.

Is GABA supplement good for sleep?

Yes, GABA has been clinically studied for sleep support. Research shows that 100mg GABA can increase deep sleep time by 2.2% and improve morning refreshment.

Nelnoda is a Functional Food certified GABA supplement for sleep quality support, registered with the Japanese Consumer Affairs Agency.

How does GABA help with sleep quality?

GABA (gamma-aminobutyric acid) is an inhibitory neurotransmitter that helps calm neural activity. This calming effect supports relaxation and helps your body transition into restful sleep.

Clinical studies show GABA supports both deeper sleep and more refreshed awakening.

Is GABA better than melatonin for sleep?

GABA and melatonin work differently. GABA calms neural activity to support relaxation, while melatonin directly signals sleep timing.

Many people prefer GABA as it supports natural sleep processes without affecting the circadian rhythm. Nelnoda provides 100mg GABA specifically studied for sleep quality support.

Is GABA or magnesium better for sleep?

Both support relaxation through different mechanisms. GABA directly calms neural activity as an inhibitory neurotransmitter, while magnesium supports muscle relaxation and nervous system function.

Nelnoda focuses on GABA at the clinically studied 100mg dose for targeted sleep quality support.

Are there any side effects of taking GABA for sleep?

GABA is generally well-tolerated. Nelnoda's 100mg dosage matches amounts used in clinical studies with healthy adults.

However, those taking blood pressure medication should consult a physician before use, as GABA may have additional effects. Discontinue use if you experience any adverse reactions.

Is GABA safe for kids?

Nelnoda was not developed for minors or children. This product is intended for adult use only.

If you are considering sleep support for a child, please consult with a pediatrician or healthcare provider for appropriate recommendations.

What makes Japanese GABA supplements different?

Japanese GABA supplements like Nelnoda are often registered as Functional Foods, requiring submission of safety and efficacy evidence to government authorities.

This regulatory framework ensures transparent ingredient disclosure and science-backed claims, providing additional assurance beyond standard dietary supplements.

When is the best time to take Nelnoda for sleep?

Take 3 tablets (1 packet) with water in the evening before your desired bedtime. Many users prefer taking it 30-60 minutes before sleep.

Consistency is important - taking Nelnoda at the same time daily helps establish a supportive routine for your natural sleep patterns.

Can I take GABA supplements with other sleep aids?

If you are taking any other medications or supplements, consult your physician or pharmacist before combining them with Nelnoda.

Those on blood pressure medication should be particularly cautious. Do not exceed the recommended daily dosage even when combining with other products.

Where can I buy quality GABA supplements for sleep?

Quality GABA supplements for sleep should be from trusted sources with transparent ingredient disclosure. Nelnoda is available through Naturacare, which curates authentic Japanese wellness products.

Look for Functional Food certification and clear dosage information when selecting a GABA supplement.
