The Science Behind Ember

Caffeine gummy diagram


What is caffeine?
One of the most widely consumed psychoactive substances worldwide, caffeine is a xanthine alkaloid compound naturally found in coffee, tea, chocolate, and the cola nut extract which is used in cola-type beverages.
What are caffeine’s typical effects?
Caffeine is often used to suppress feelings of fatigue and increase feelings of energy and concentration.
How does caffeine work?
Caffeine crosses through the blood–brain barrier and, once in the brain, indirectly increases neurotransmitter activity by blocking adenosine receptors. Accumulation of adenosine in the brain inhibits arousal and increases drowsiness.
How much caffeine is safe?
For healthy adults, the FDA has stated that up to 400 milligrams a day is not generally associated with dangerous, negative effects. Note: there is considerable variation in each person’s (i) sensitivity to the effects of caffeine and (ii) speed with which they metabolize (break down) caffeine.
How much caffeine is in typical products?
According to the FDA:


What is L-Theanine?
A non-protein amino acid found naturally in tea.
What are L-Theanine’s typical effects?
Certain studies have found that L-Theanine can contribute to a relaxed and alert feeling at rest, and is associated with improved cognitive function.
How does L-Theanine work?
L-Theanine crosses the blood–brain barrier and has been reported to increase electrical activity in the brain.

Caffeine and L-Theanine

Why combine caffeine and L-Theanine?
Certain studies suggest there is a synergy between both caffeine and L-Theanine. In one such study, L-Theanine and caffeine in combination appeared to improve aspects of memory and attention to a greater extent than caffeine alone. Caffeine and L-Theanine are often found in tea, and are used as ingredients in “nootropic” products.

Disclaimer: ember is intended for use by healthy individuals only and is not recommended for children, pregnant or nursing women, or persons sensitive to caffeine. There may be considerable variation in each person’s (i) sensitivity to the effects of caffeine and L-Theanine and (ii) speed with which each person metabolizes (break down) caffeine and L-Theanine.
