Caffeine and L-Theanine: Coffee, Tea, or Supplements?

caffeine from starbucksImagine having the focus of a Zen master with the energy of a cheetah. Combining caffeine and L-theanine can help make that a reality.

Most people are familiar with the idea of caffeine based energy, otherwise there wouldn’t be a Starbucks on every corner, but the focus part is what’s most important.

Running around in circles will get you nowhere, but caffeine AND L-theanine gives you the ability to think in a clear, strategic way while your energy levels are high.


The first component is the caffeine. Even through it’s a nervous system stimulant, caffeine can be beneficial if taken in the right frequency and doses. When used appropriately, it can improve focus, energy, cognition and even mood. However, if you get too much caffeine it can have a nasty jittery effect and leave you feeling burned out very quickly. Also, caffeine needs to be cycled in order to stay effective and avoid tolerance buildup.

Coffee vs Caffeine Supplements

Most people get their daily caffeine through drinks like coffee. Coffee is one of the most consumed beverages in the world. It’s used by students and executives alike to get their day started. If you’re going to consider using it for nootropic purposes, however, there are some things to consider.

First, you need to be scientific with it. One cup of coffee doesn’t always have the same amount of caffeine as the next, especially if you’re getting mixed coffee drinks or coffee from different sources each day. The actual caffeine content can vary drastically if you don’t have strict control over how strong or big the cup of coffee is.

Bulk Caffeine Supplements

The alternative is to go with bulk caffeine supplements. This can be accurately measured and taken in consistent doses so you know what you’re actually getting each and every time. You can also use bulk caffeine in custom pre-made stacks or capsules. Plus, it is less expensive than coffee in the long run if you’re drinking high quality coffee or daily lattes.

L-theanine Powder

This supplement is a naturally occurring amino acid that was originally discovered in green tea. On its own, l-theanine works within the central nervous system to provide anxiolytic (anti-anxiety) or calming effects.

L-theanine promotes alpha wave activity in the brain. Alpha waves are the brain waves produced in a relaxed, awakened state, so it’s easy to see how this supplement can help calm you.  Like caffeine, l-theanine is available in bulk which gives you the ability to mix it into custom stacks and accurately measure each dose.

L-Theanine Powder and Caffeine

Despite the two supplements having what seem like drastically different effects on the body, the net effect of the caffeine l-theanine combo is a synergy that gives you the energy of caffeine but with a calm focus.

This combination is one that, whether they knew it or not, monks have used for thousands of years. Teas, which contain small amounts of caffeine and l-theanine, were staples of their mediation practices, giving them the energy to stay awake and the focused calmness to stay in their state for hours at a time.

L-Theanine Powder and Caffeine Dosage

L-Theanine Powder can be weighed with a milligram scale for accurate dosing

Use a digital milligram scale to accurately weight your supplements.

L-theanine and caffeine dosages are measured in ratios as opposed to total mg. The recommended ratio of l-theanine to caffeine is 2:1, meaning you should take two parts theanine for one part caffeine.

Again, this is where bulk caffeine is more beneficial since you can get a clean measurement. Starting doses can vary depending on your own caffeine intake and tolerance. If you’re not a caffeine drinker at all, then 50mg caffeine and 100mg l-theanine may be ideal. And if you’re a heavy caffeine user already, you’ll need to adjust the ratios to your current intake.

Don’t like using milligram scales? Then check out these caffeine L-theanine capsules. You will get all the same benefits without the extra work.

What to Expect with Caffeine and L Theanine Powder

When you are able to dial in your ideal dosage, you will notice a few things. First, you will be alert. This wont be news for any coffee drinkers or caffeine users. Second, you wont have a jittery edge to your caffeine buzz. And finally, you’ll find it easier to focus. The effects may seem more or less subtle depending on your current supplement usage, but in general you’ll have a calm, focused energy to get you through your day with no jittery anxiety.
