200mg L-Theanine Powder
L-Theanine fits into the part of your routine where you want calm focus—on its own, or alongside caffeine before training or deep work.
This is a single-ingredient L-Theanine powder in a convenient 1 gram pack, clearly dosed at 200mg per pack. It is straightforward to stack and easy to track—one compound on the label, one compound in the pack. No proprietary blends, no hidden ratios, and nothing to interpret beyond the amount you choose to measure into your shaker or mug.
- Each 1 gram pack contains 200mg of L-Theanine, supporting steady, composed focus and smoothing the edge of stimulants.
Use it the way you already manage your training and focus blocks. Measure the amount you prefer with a scale or level scoop, add to cold or room-temperature water, and shake or stir until dissolved. Many people pair L-Theanine with their morning coffee for a more even feel, add it to a pre-workout when caffeine is in the mix, or take it on its own during study or late-day sessions when they want focus without more stimulation. It stacks cleanly with other single-ingredient basics—combine it as you like, keeping the 200mg per 1 gram pack in mind as you build your routine.
Because there is no fixed serving in this format, you keep full control: use more or less based on context, timing, and how you respond. Start with a modest amount the first few times to learn your preference, then adjust as needed for work blocks, travel days, or recovery days when you still need your head in the game.
Scientific Blends keeps things simple: one compound per product, stated plainly on the front, with a clear dose you can count on—200mg in every 1 gram pack. That transparency is the point here. No blends, no fillers called out, no marketing story standing between you and the label. Just a consistent, single-ingredient powder you can place exactly where it belongs in your stack. As with any dietary supplement, use it as part of your normal training and nutrition plan and consult a professional if you have specific questions about your situation.

Frequently Asked Questions
L-Theanine is a non-protein-forming amino acid naturally found in tea leaves. Supplement powders provide the isolated compound, so they are not the same as brewed tea, which can contain caffeine and other components.
Human studies have examined L-Theanine for attention and stress-related outcomes. Results vary by study and population, and reviews note that the clinical relevance remains uncertain. It should not be expected to produce the same effect for every person.
Measure and mix L-Theanine powder only as directed on its label. When combining it with tea, pre-workout products, or other supplements, check every label for caffeine and overlapping ingredients.
