What is Theobromine? Theobromine is an alkaloid chemical substance found in a handful of plants around the world. Most notably it comes from the cacao plant and is the active ingredient in chocolate. It provides a non-jittery boost of energy, improves your cholesterol profile, dilates blood vessels to allow more blood flow which helps improve cardiovascular health, and improves your mood and overall sense of well being. How does Theobromine work? Much like caffeine, Theobromine is a stimulant that increases focus, wakefulness, performance, among a myriad of other benefits. However Theobromine is quite different chemically from caffeine and therefore produces a smoother, less intense, less jittery level of energy than caffeine. How Theobromine works in the brain is that it binds to the neurotransmitter receptor adenosine without activating it. By blocking adenosine from reaching the receptors, it creates a heightened level of mental alertness and focus. It also acts as a vasodilator, helping promote blood flow throughout the body; relaxant for the smooth muscles of the lungs, increasing respiration; and is a mild diuretic, increasing urine production. Why use Theobromine? Improves cardiovascular health by being a vasodilator Smoother and longer lasting energy than Caffeine Enhances focus and ability to concentrate for long durations of time Increased mental clarity Increased energy levels Helps prevent tooth sensitivity How to use Theobromine? 500mg-1000mg per day of Theobromine is the typical dose that should produce all the desired effects, with zero to minimal side effects in most individuals. Theobromine is also known to work well when combined with other cognitive enhancing nootropics. Classes of Theobromine Some companies sell Theobromine as “cocoa extract”. Theobromine falls into the alkaloids and stimulants classes of compounds. Possible Side Effects of Theobromine Theobromine is considered to be safe when used appropriately. Theobromine is a lethal ingredient to dogs so make sure you keep it out of reach and safe if you have a dog. Theobromine is the same ingredient in chocolate that is known for killing dogs and is the exact reason why it is a widely known fact that it is very dangerous for a dog to consume chocolate. In very rare cases where humans have taken an excessive amount of Theobromine, some possible side effects included sleeplessness, tremors, restlessness, anxiety, increased urine production, loss of appetite, nausea, vomiting, and withdrawal headaches.
