Caffeine jewelry is here at last! The molecule form of everyone's favorite stimulant is cast in sterling silver and can be worn proudly from one's neck or ears. The most widely consumed psychoactive substance in the world, caffeine causes a surge in norepinephrine, keeping us awake and alert. It also binds to adenosine receptors on the surface of cells ni the brain, reducing adenosine activity and increasing the neurotransmitter dopamine (see the Dopamine Earrings), causing a feeling of happiness and enjoyment. And, it increases serotonin levels (check out the Serotonin Necklace and Earrings), leading to a feeling of being at ease and content.

Caffeine is awesome!

These earrings are about 3/4" wide.
