Why It Works
What is L-Theanine?
L-Theanine is an amino acid naturally found in green tea leaves. Unlike caffeine, L-Theanine is not a stimulant. It supports a smoother, gradual rise in energy, mental clarity, and focus. L-Theanine has been consumed for centuries as part of traditional tea drinking cultures around the world.
What does caffeine actually do?
Caffeine works by blocking adenosine receptors in your brain (the receptors that signal tiredness). This gives energy and alertness. But also the overstimulation, and the crash when it wears off. Coffee gives you the energy and the noise as a package deal. Most people have learned to accept both. They don't have to.
Coffee + L-Theanine
L-theanine promotes alpha wave activity in the brain. Alpha waves are associated with a state of calm, alert focus. Combined with caffeine, L-theanine smooths the edges of stimulation without touching the energy. The result is something neither delivers alone. The alertness of caffeine except smoother, more sustained, and no jitters. This is how your coffee should always feel.
Why 200mg?
A standard cup of coffee contains roughly 80 to 100mg of caffeine. Research consistently shows that doses at 200mg, L-Theanine is present to work alongside that caffeine without dulling it. Each Althea packet contains 200mg. One packet, one cup, the right dose every time. No measuring, no guessing, no adjusting.
Is it safe?
L-Theanine has been consumed in green tea for centuries and is widely studied. It is non-habit forming and is one of the most studied pairings in functional nutrition research.
Your coffee was already good. Althea makes it feel exactly how it should.
