Drinking + TGAC and the Brain
When you consume alcohol faster than your liver can metabolize it, alcohol builds up in your bloodstream. Your blood alcohol content (BAC) rises, and alcohol has pervasive effects on your brain and you begin to feel drunk.
When alcohol reaches your brain it affects two different neurotransmitters. Simply put, neurotransmitters are chemicals your brain cells use to control emotions, movement, behaviour, and thought processes. Two categories of neurotransmitters are inhibitory and exhibitory. Inhibitory neurotransmitters have a calming effect and “slow” things down. Exhibitory neurotransmitters increase energy levels and brain activity.
One neurotransmitter affected by alcohol is GABA. Alcohol binds to GABA receptors in your brain and amplifies its effect. As the brain receives a stronger message from GABA, you begin to feel calm, and your heart rate slows down.
When you continue to drink, GABA signals are amplified further and further. Eventually, you experience loss of motor control, inhibitions are lowered, and your speech begins to slur.
(Additionally it is worth noting that when alcohol is consumed at a dangerous level, your breathing and heart rate can slow down to the point you can experience coma, or even death.)
TGAC works because Dihydromyricetin blocks the Alcohol from affecting GABA Receptors. Dihydromyricetin binds to GABA receptors in the brain and blocks the effect alcohol has on GABA receptors.  Theoretically, this should reduce certain feelings related to intoxication as alcohol is only amplifying the exhibitory neurotransmitter Glutamate (another neurotransmitter affected by alcohol). This theory was put to the test, and has held up in various studies.
When TGAC is taken before drinking, alcohol can’t amplify GABA and you don’t feel as intoxicated. When TGAC is taken after drinking, it can accelerate the rate at which one sobers up. TGAC’s benefit on the brain isn’t just limited to GABA receptors. Dihydromyricetin is also a potent antioxidant able to prevent damage done by alcohol to dendrites.
