Quicksilver Scientific GABA + L-Theanine

The night before a race, or after a late interval session, your legs are done but your mind keeps running. Hard training, early alarms, and work deadlines all push your nervous system toward its sympathetic "fight-or-flight" side, and the parasympathetic "rest-and-digest" side that handles winding down gets less room to work.

Quicksilver Scientific's Liposomal GABA + L-Theanine pairs two calming compounds in a liquid you take by mouth, giving you a way to support a relaxed, focused state when it is time to settle down.

Supports a healthy stress response – GABA is the brain's main calming neurotransmitter, a chemical messenger that helps nerve cells quiet their signaling. This formula gives your nervous system added support when training load and daily life stack up.

Supports relaxation and focused calm – L-theanine is an amino acid found in green tea that supports relaxation and focus. That pairing helps you wind down while staying mentally sharp, which matters when you are packing a race bag or going over a pacing plan.

Supports mood and emotional balance – GABA and L-theanine together support mood as well as relaxation. You take it on an empty stomach before a meal, so it fits easily into a pre-dinner or evening wind-down routine.

The liposomal delivery system from Quicksilver Scientific wraps these ingredients in liposomes, which are tiny fat-based bubbles that carry nutrients. This design is meant to support absorption and bioavailability, which is the amount of a nutrient your body can actually use. Holding the liquid in your mouth before swallowing gives it time in contact with the tissue there before it moves on.

How to Use GABA + L-Theanine

Dose: Take 2-4 pumps by mouth and hold the liquid in your mouth for 30-90 seconds before swallowing. Repeat to reach your desired dosage.

Timing: Take it on an empty stomach, at least 10 minutes before meals. Many athletes will find the evening before dinner or after a late session the easiest slot to stay consistent with.
