What is it: GABA, or Gamma-Aminobutyric Acid, is a neurotransmitter naturally produced in the brain that plays a crucial role in regulating brain activity and promoting relaxation. It is known for its calming effects on the nervous system and has been popular for decades for it’s ability to promote a deeper sleep.
Who Should take it: Individuals who experience stress, anxiety, or have trouble with relaxation and sleep may benefit from GABA supplementation. Athletes and fitness enthusiasts looking to support recovery and reduce muscle tension may also find GABA beneficial.
What does it do: GABA acts as an inhibitory neurotransmitter in the brain, helping to reduce neuronal excitability and promote feelings of calmness and relaxation. It can help alleviate symptoms of anxiety, improve sleep quality, and support overall mental well-being.
In a study with a GABA product derived from fermented barley (Sanwa GABA), men and women between the ages of 39 and 59 were given either 100 mg of GABA or a placebo 30 to 60 minutes before bedtime. Results showed GABA significantly increased deep sleep in subjects over 44 years old and also those subjects experiencing psychological stress or fatigue.
In another double-blind study with GABA, 62 subjects experiencing sleep problems, stress, and fatigue experienced significant improvements in sleep quality, subjective ratings of fatigue, and perceived feelings of vitality.
How to take it: Studies on GABA supplementation have shown varying effective doses, typically ranging from 100mg to 800mg per day. However, individual responses to GABA may vary, and it is recommended to start with a lower dose and gradually increase as needed. Most people take GABA 30 to 60 minutes before bed.
