Caffeine + L-theanine

Combining caffeine and the relaxing amino acid L-theanine, found naturally in tea, produces synergistic effects which provide wakefulness that is calmed by the gentle effects of L-theanine.

Caffeine + L-Theanine Combination Benefits

  • May improve cognitive performance 
  • Promotes the benefits of caffeine without unwanted effects 
  • Supports focus and attention 
  • Promotes wakefulness and alertness 
  • L-Theanine is General Recognized As Safe (GRAS) by U.S. FDA 

Caffeine + L-Theanine Mode of Action

L-Theanine

L-Theanine is an amino acid which naturally occurs in tea leaves and some forms of mushrooms.  Tea (Camellia sinensis) contains 1-3% of L-theanine. It is used in a supplemental form isolated directly from tea leaves or prepared via chemical synthesis or biosynthesis (1). Green, black, oolong and white tea all contain L-Theanine in varying amounts (2).

L-Theanine is absorbed through the intestines and reaches the blood-brain barrier in approximately 50 minutes after ingestion, similarly to the absorption through natural tea leaves(1).  L-Theanine can be found in the brain in the hippocampus (3) after ingestion–the area of the brain responsible for learning and memory (4).

Research in animals suggests that L-Theanine (L-gamma-glutamylethylamide) works through glutamate receptors and increases levels of GABA and glycine in the brain, which causes relaxation. Increased GABA and glycine may increase serotonin and dopamine; however, it has also been noted that theanine may decrease or inhibit serotonin synthesis (1).

Caffeine

Caffeine is a stimulant found in coffee, tea, chocolate, guarana, yerba mate, and the kola nut.  It is an adenosine receptor antagonist, meaning that it prevents adenosine from being active.  Adenosine is one of the neurotransmitters responsible for drowsiness, and caffeine provides wakefulness through this mechanism of blocking adenosine (5).

Caffeine also interacts with the serotonergic system and can cause changes in the acetylcholine and dopamine systems within the body (5). Caffeine does produce side effects, such as large amounts acutely raising blood pressure. Mild side effects can include anxiety, agitation, restlessness, fidgeting, irritability, elevated or irregular heart rate, and others (6). 

L-Theanine + Caffeine Combination

By combining L-theanine with caffeine, some of the undesirable side effects of caffeine use are lessened.  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 (5).

The combination of L-theanine with caffeine also may improve cognitive function (7), may eliminate the blood vessel constriction normally experienced with caffeine (8), and help keep the mind from experiencing wandering, or distraction (9).

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 (10).

Caffeine + L-Theanine Dosage

Pure Nootropics’ Caffeine + L-Theanine provides 100 mg of caffeine and 200 mg of L-Theanine per 1 capsule.  Suggested use for adults is 1 capsule by mouth once daily, or as directed by your healthcare practitioner.

Caffeine + L-Theanine Side Effects and Toxicity

  • 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 (11).

Animal research indicates that the No Observed Adverse Effect Level of L-theanine is greater than

4000 mg/kg in rats (11).

(Note:  Due to L-Theanine’s effects on reducing blood pressure, please see the list of possible interactions with pharmaceutical blood pressure medications)

Using Herbs and supplements that lower blood pressure should also be avoided when taking L-Theanine due to the same mechanism of L-Theanine on blood pressure that applies to pharmaceutical medications. Some of these herbs and supplements include casein peptides, cat’s claw, Andrographis, coenzyme Q10, L-arginine, fish oil, lyceum, stinging nettle, and others (11).

L-Theanine may reduce the effects of caffeine and mask the symptoms of taking too much caffeine.  These include the effects of energy drinks, coffee, black tea, oolong tea, guarana, mate, cola, and others.  Please be aware of your caffeine consumption during supplementation with L-Theanine (11).

  • 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 (12).

The lethal dose of caffeine in adults is approximately 10-14 grams per kilogram, but fatality has also occurred at lower doses (12).

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.  

If you are taking any medications, herbs, or supplements, please consult your healthcare practitioner before beginning supplementation with caffeine.

  • GRAS (Generally Recognized as Safe) 

 Optimal Energy Complex Mode of Action

Optimal Energy Complex focuses on methylxanthines (a class of stimulatory compounds), alkaloid compounds which are similar in structure to methylxanthines, and the amino acid found in green tea, L-Theanine. Caffeine, Theobromine, and L-Theanine can all be found naturally occurring together in some teas (3). 

Methylxanthines

Methylxanthines include Caffeine and Theobromine and are found together in cocoa, cacao, and chocolate (3). 

Caffeine

Caffeine is a stimulant found in coffee, tea, chocolate, guarana, yerba mate, and the kola nut.  It is an adenosine receptor antagonist, meaning that it prevents adenosine from being active.  Adenosine is one of the neurotransmitters responsible for drowsiness, and caffeine provides wakefulness through this mechanism of blocking adenosine (4).

Caffeine also interacts with the serotonergic system and can cause changes in the acetylcholine and dopamine systems within the body (4). Caffeine does produce side effects, such as large amounts acutely raising blood pressure. Mild side effects can include anxiety, agitation, restlessness, fidgeting, irritability, elevated or irregular heart rate, and others (5).

Theobromine

Theobromine is a mood-enhancing compound naturally present in chocolate.  Theobromine is a mild stimulant that interacts with the dopamine pathways in the brain (6).  Theobromine stimulates the central nervous system by blocking adenosine receptors (7).

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 (8).

Alkaloids similar to methylxanthines

Theacrine and Dynamine™ (Methylliberine) are similar to methylxanthines, but they are structurally different.

Theacrine

Theacrine occurs in Kucha tea leaves and is very similar to a caffeine molecule (1).  Theobromine and caffeine in certain plants will convert into Theacrine (9).  Theacrine causes signaling changes on the adenosine receptors in the brain, like caffeine, and can also influence the dopaminergic signaling pathways like caffeine.  However, unlike caffeine, Theacrine is non-habit forming and does not change the heart rate or blood pressure (1).  When combined with caffeine, bioavailability is enhanced (10).

Dynamine™ (Methylliberine)

Dynamine™ (Methylliberine) is an isomer of Theacrine, and it can be found in kucha tea and some species of coffea.  It is a byproduct of metabolic reactions between the methylxanthines and methyluric acid.  The plants accumulate caffeine and begin transforming theobromine to caffeine.  The caffeine and theobromine are converted to Theacrine, and Theacrine replaces all of the caffeine.  Theacrine will then be reduced, as levels of liberine rise, and its precursor methylliberine is present (9).

Dynamine™ (Methylliberine) provides the effects of Theacrine without any changes in heart rate or blood pressure elevations, and the combination of the two has demonstrated that they are synergistic (2).

L-Theanine

L-Theanine is an amino acid which naturally occurs in tea leaves and some forms of mushrooms.

Tea (Camellia sinensis) contains 1-3% of L-theanine. It is used in a supplemental form isolated directly from tea leaves or prepared via chemical synthesis or biosynthesis (11). Green, black, oolong, and white tea all contain L-Theanine in varying amounts (12).  Green tea and black tea contain the highest amounts of L-theanine, but the studies are conflicted about which of the two has the most (13).

Combined with caffeine, L-Theanine may improve performance on cognitively demanding tasks through its synergistic effects.  L-Theanine may help control blood pressure and may lessen some of the unwanted effects of caffeine (14).

Optimal Energy Complex Dosage

Pure Nootropics’ Optimal Energy Complex provides 100 mg of Caffeine, 200 mg of L-Theanine, 125 mg of Theacrine (TeaCrine®), 125 mg of Dynamine™ (Methylliberine), and 150 mg of Theobromine per 1 capsule.  Suggested use for adults is 1 capsule by mouth once daily.

Dynamine™ is a trademark and TeaCrine® is a registered trademark and protected by Patents Pending, Serial No. 61/903,362; under exclusive global distribution by Compound Solutions, Inc.

Optimal Energy Complex Side Effects and Toxicity

If you are taking any medications, herbs, or supplements, please consult your healthcare practitioner before beginning a supplementation with this product.

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 (15).

The lethal dose of caffeine in adults is approximately 10-14 grams per kilogram, but fatality has also occurred at lower doses (15).

Caffeine has many pharmaceutical medication and herb interactions.

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 (11).

Animal research indicates that the No Observed Adverse Effect Level of L-theanine is greater than

4000 mg/kg in rats (11).

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 (8). 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 (16).

Theobromine is very toxic to dogs because they metabolize it so slowly, and they can experience theobromine poisoning (17). Please keep Optimal Energy Complex out of the reach of curious pets.

Theacrine (TeaCrine®) Side Effects

Theacrine (TeaCrine®) is considered GRAS by the U.S. FDA (Generally Recognized As Safe).

The lethal dose for mice was achieved at 810.6 mg/kg, which equates to 4 g per a 76 kg human (18).

Dynamine™ Capsules Side Effects

Toxicology studies are currently taking place for Dynamine™.  It is believed to be similar to Theacrine (TeaCrine®) in that it does not affect blood pressure and heart rate like caffeine can.

  • Theobromine

Theobromine is a mood-enhancing compound naturally present in chocolate. Theobromine is a mild stimulant that interacts with the dopamine pathways in the brain (7). Theobromine and caffeine are both methylxanthines that stimulate the central nervous system through blocking adenosine receptors (8). 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 (9).

  • 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 (10).

Animal research indicates that the No Observed Adverse Effect Level of L-theanine is greater than

4000 mg/kg in rats (10).

(Note: Due to L-Theanine’s effects on reducing blood pressure, please see the list of possible interactions with pharmaceutical blood pressure medications and herbs/supplements that may occur below.)

Regarding interactions with other medications/herbs/supplements: If you are taking blood pressure medications (antihypertensive medications) to lower blood pressure, be moderately cautious combining those medications with L-Theanine, as evidence in animal research has noted that L-Theanine may lower high blood pressure. Using L-Theanine and antihypertensive medications may lower blood pressure too much. Some of these medications include Vasotec (enalapril), Capoten (captopril), Cozaar (losartan), Diovan (valsartan), Norvasc (amlodipine), Cardizem (diltiazem), HydroDiuril (hydrochlorothiazide), Lasix (furosemide), and others). Please consult with your healthcare practitioner if you are on any blood pressure medications prior to beginning supplementation with L-Theanine (10).

Using Herbs and supplements that lower blood pressure should also be avoided when taking L-Theanine due to the same mechanism of L-Theanine on blood pressure that applies to pharmaceutical medications. Some of these herbs and supplements include casein peptides, cat’s claw, Andrographis, coenzyme Q10, L-arginine, fish oil, lyceum, stinging nettle, and others (10).

If you are taking any stimulant medications, using L-Theanine and the stimulants together may decrease the effectiveness of the prescribed stimulants, some of which include epinephrine, Tenuate (diethylpropion), Lonamin (phentermine), Sudafed (pseudoephedrine), and others (10).

  • 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.

Best Caffeine Pills Ingredients

In 2020, the most effective nutritional supplements — including caffeine supplements — leverage the power of nutrient stacking.

In this practice, nutrients that complement each other or synergize with each other are combined to produce greater results than if those same nutrients are taken alone.

Supplements that supply only caffeine fail to unlock its full potential.

Advanced supplements now formulate using caffeine combos that help the world’s greatest natural performance-enhancer to work even better.

Let’s take a closer look at the top ingredients and key features that are found in today’s best caffeine supplements.

Low-Dose Caffeine

Caffeine is basic. You can get it from many different sources in all kinds of products, including coffee beans, guarana, green tea, cacao, and even synthetic caffeine.

Today, most consumers are looking for the cleanest possible source of caffeine that works the best with their lifestyle. In that regard, anything label listing natural caffeine will do.

More important than the source is how caffeine is dosed in supplements.

Have you ever noticed while working under pressure that downing cup after cup of coffee at some point simply stops working?

You might feel quite alert after the first couple of cups, and note that your performance is improved.

But if you keep on consuming caffeine, you may notice your performance getting markedly worse.

Excessive caffeine intake is associated with a list of performance-crushing side effects, including:

  • nausea and gastric distress
  • nervousness, jitters, anxiousness
  • heart palpitations and accelerated heart rate
  • mood swings and irritability
  • headaches
  • difficulty falling asleep and staying asleep

Many caffeine supplements fail to boost performance because their megadoses produce too many disruptive side effects.

Precision dosing is a game-changer for caffeine supplements.

That’s because each of us has a specific caffeine dosage that will be associated with the greatest performance enhancements.

  • Too little caffeine, and you won’t feel any performance-enhancing stimulation
  • Too much caffeine leads to overstimulation, which manifests as performance- and recovery-diminishing side effects
  • Optimal caffeine dosage hits the stimulant sweet spot: Sharp alertness, clean energy, and a crash-free mood lift

The best caffeine supplement of 2020’s precision dosing gives you greater control over caffeine intake, enabling superior performance benefits.

Some caffeine pills may supply up to 300 mg of caffeine per serving. This is a clumsy approach to dosing.

A caffeine supplement that supplies 50 mg of caffeine per serving – about the dosage of a small cup of coffee – enables you to achieve superior stimulation results than one imprecise megadose of 250 mg caffeine or more.

Caffeine pills with 50 mg dosage allows incremental adjustments for fine-tuning your stimulation experience. Take more capsules as needed, until you determine your optimal caffeine dosage for peak human performance.

L-Theanine

L-Theanine is a natural amino acid that is found in green tea that helps make caffeine’s effects even better for performance.

Have you ever noticed drinking green tea produces different caffeine effects from drinking a cup of coffee?

For most people, drinking a cup of green tea is associated with alertness and energy that is calmer and smoother than the stimulation state that is produced by caffeine alone.

Green tea’s distinct stimulation effects are attributed to its lower-dose caffeine and natural L-Theanine.

L-Theanine works to raise Alpha brain waves that are associated with feelings of relaxed alertness.

This unique bioactivity complements caffeine, helping to provide an energized-and-alert state that remains calm, clear-headed and focused under pressure.

Caffeine + L-Theanine is an extensively reviewed and research-backed performance-enhancing stack that belongs in all of the best caffeine supplements.

Across multiple human clinical trials and reviews, researchers have linked Caffeine + L-Theanine to:

  • Improved speed and accuracy at attention-switching tasks and improved memory task performance in a distracting setting
  • Reduced caffeine side effects, with L-Theanine notably helping with caffeine-induced vasorestriction
  • Synergistic beneficial effects on attention performance when taken at sufficiently high doses
  • Enhanced cognitive performance and improved alertness, along with greater attentional focus on challenging tasks

The best caffeine supplements of 2020 must include L-Theanine to capitalize on its natural, safe, and effective synergy with caffeine.

Taken together, caffeine + L-Theanine appear to promote a superior stimulation state than when they are taken alone.

Best L-Theanine for Caffeine Supplements: Suntheanine®

Protected by 40+ patents, Suntheanine® is the most research-backed form of L-Theanine, and the only L-Theanine that has been shown in research to raise relaxing Alpha brain waves. Every 100 mg Suntheanine® supplies about as much L-Theanine as 10+ cups of brewed green tea.

L-Tyrosine

The body uses amino acid L-Tyrosine as a building block to produce performance-oriented brain chemicals called catecholamines:

  • Epinephrine (adrenaline)
  • Norepinephrine (noradrenaline)
  • Dopamine

Caffeine stimulation may be associated with stressful states including multitasking, overwork, sleep deprivation, and burnout. Stress in turn is suggested to deplete the catecholamine brain chemicals or otherwise lead to brain chemical inbalances.

L-Tyrosine in supplement form may help to support stress-depleted neurotransmitters.

Today’s best caffeine supplements include L-Tyrosine to help offset brain chemical disruptions associated with an overcaffeinated, hectic and overworked lifestyle.

Best L-Tyrosine for Caffeine Pills: Ajinomoto®

There are a lot of tyrosine supplements and forms on the market. But the best tyrosine is always going to be by Ajinomoto®.

Established in 1909, Ajinomoto® is a legendary amino acid supplement innovator and inventor of Ferment-A-Pure technology – a patented, eco-friendly process that turns non-GMO and gluten free vegetable carbohydrates into bioavailable amino acids.

Ajinomoto® amino acids, including tyrosine, are found in the world’s best stim, nootropic and sport nutrition supplements — including the top caffeine supplement overall.

B-Complex Vitamins: Folate, B6, Riboflavin, B12

Folate, B6, Riboflavin and B12 are among the B-Vitamins that may be depleted by caffeine use.

Notably, these B-vitamins are required for cell energy and optimal neurotransmitter synthesis and conversion.

Today’s top stim supplements are now including B-Vitamins that are carefully calibrated to help restore what caffeine might be taking away.

In caffeine supplements, B vitamins may help to support stim recovery, neurotransmitter balance and an overall healthier stimulation experience.

Best B-Vitamins for Caffeine Supplements: NutriGenesis®

NutriGenesis® B-Vitamins are fermented in a clean lab and include natural cofactors that enhance their absorption. NutriGenesis® bioavailability advantages are ideal for reversing caffeine-induced nutrient depletion.

Performance Lab® Stim unites all of today’s best caffeine supplement ingredients into one quality formula:
