Discover the benefits of the L- Theanine and caffeine combination. You can experience an improvement in both speed and accuracy of the performance of the attention - switching task, reduced susceptibility to distracting information in the memory tasks.
Caffeine + L-Theanine in our 1-2 GO Benefits
- May improve cognitive performance
- Promotes the benefits of caffeine without unwanted effects
- Supports focus and attention
- Promotes wakefulness and alertness
- L-theanine is approved by the U.S FDA
A naturally occurring, mild stimulant responsible for the mood-enhancing effects of cocoa.
Caffeine and Theobromine are found naturally combined in cocoa, cacao, and chocolate. Caffeine, Theobromine, and L-Theanine can all be found in some teas as well.
- Caffeine + L-Theanine Combination
By combining L-theanine with caffeine, some of the undesirable side effects of caffeine use is decreased. L-Theanine reduces caffeine’s stimulatory effects without modifying the other mechanisms for focus that caffeine offers. L-Theanine interacts with caffeine by “taking the edge off” and still allows the alertness provided by caffeine to remain.
The combination of L-theanine with caffeine also may improve cognitive function, may eliminate the blood vessel constriction normally experienced with caffeine, and help keep the mind from experiencing wandering, or distraction.
The cognitive benefits associated with caffeine in combination with L-Theanine were studied on 50 mg caffeine to 100 mg L-Theanine, so we recommend caffeine to L-Theanine ratio should be 1-part caffeine to 2 parts L-Theanine.
Theobromine is a mood-enhancing compound naturally present in chocolate. Theobromine is a mild stimulant that interacts with the dopamine pathways in the brain. Theobromine and caffeine are both methylxanthines that stimulate the central nervous system by blocking adenosine receptors. In comparison to caffeine, Theobromine is a much weaker stimulant and only exerts about one-tenth of the effects of other methylxanthines (Review Article Health Benefits of Dark Chocolate).
The combination of caffeine and theobromine in chocolate, cocoa, and cacao is linked to the pleasurable effects and appeal of chocolate. Theobromine has also shown promise in promoting blood vessel health.

1-2-GO Side Effects
- L-Theanine Side Effects
L-Theanine, regardless of chemical synthesis, biosynthesis, or naturally occurring, is General Recognized As Safe (GRAS) by U.S. FDA.
L-Theanine is very well tolerated and side effects may include headaches and increased sleepiness.
Animal research indicates that the No Observed Adverse Effect Level of L-theanine is greater than 4000 mg/kg in rats.
(Note: Due to L-Theanine’s effects on reducing blood pressure, possible interactions with pharmaceutical blood pressure medications, and herbs/supplements that may occur.)
- Caffeine Side Effects
In moderate doses, caffeine is usually well-tolerated in adults and children. Side effects may include insomnia, restlessness, nervousness, nausea, vomiting, gastric irritation, tachycardia, tremors, quickened respiration, convulsions, headache, agitation, anxiety, chest pain, and irregular heartbeat. Large doses of caffeine may cause tachycardia, metabolic acidosis, ketosis, and hyperglycemia. Children and the elderly may experience more adverse effects from caffeine. Chronic use of large amounts of caffeine may cause tolerance, psychological dependence, and abrupt stopping of caffeine use may cause physical withdrawal symptoms.
The lethal dose of caffeine in adults is approximately 10-14 grams per kilogram but fatality has also occurred at lower doses.
Caffeine has many pharmaceutical medication and herb interactions. If you are taking any medications, herbs, or supplements, please consult your healthcare practitioner before beginning supplementation with caffeine.
- Theobromine Side Effects
Theobromine is toxic to many animals, but in normal consumption, it is safe for humans. A standard 40 g dark chocolate bar contains about 250 mg of Theobromine. Chocolates with higher cocoa/cacao content have more theobromine than milk chocolate.
Higher doses of 50-100 g of cocoa caused sweating, severe headaches, and trembling.
Theobromine is very toxic to dogs because they metabolize it so slowly and they can experience theobromine poisoning. Please keep 1-2-GO out of the reach of curious pets.
