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:2

  • 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.3

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 setting4
  • Reduced caffeine side effects, with L-Theanine notably helping with caffeine-induced vasorestriction5
  • Synergistic beneficial effects on attention performance when taken at sufficiently high doses6
  • Enhanced cognitive performance and improved alertness, along with greater attentional focus on challenging tasks7

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 amio 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.8

L-Tyrosine in supplement form may help to support stress-depleted neurotransmitters.9

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.10

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.
