Sports Research L-Theanine + Caffeine - 2-in-1 Nootropic for Calm Focus (60 Softgels)

What is in the softgel, and why

This is a two-ingredient stack with a carrier oil, no filler cast of kitchen-sink botanicals. Two active compounds, both at doses that match the clinical literature rather than a token sprinkle.

How the two work together

• Caffeine (100 mg) works mainly by blocking adenosine, the molecule that builds up through the day and signals your brain to wind down. Block that signal and you feel more alert. The trade-off for a lot of people is the familiar downside: jitter, a faster heartbeat, some anxiety, then a dip when it wears off.
• L-theanine (200 mg) is an amino acid from tea that does cross the blood-brain barrier (a common question, and yes, it reaches the brain). It is associated with increased alpha brain-wave activity, the relaxed-but-alert state people also describe from meditation, plus gentle modulation of GABA and dopamine signaling. On its own it can help support a calm state without sedation.
• Together, the theanine is there to smooth caffeine's rough edges while leaving the alertness intact. The result most people describe, and the reason this combo became the entry point for the whole category, is smooth focus.

The ratio question (the part that matters most)

The studied range for this stack is roughly 100 to 200 mg caffeine with 100 to 200 mg theanine. Where you land inside that range changes the feel:

• 1:1 (equal parts) is balanced, a touch more stimulant-forward.
• 1:2 caffeine-to-theanine is calmer and theanine-dominant, the profile people reach for when straight caffeine feels like too much.

This product is a clean 1:2 (100 mg caffeine to 200 mg theanine), deliberately on the calmer side. That makes it a good fit if you are caffeine-sensitive, prone to the coffee jitters, or doing focused desk work where you want steady rather than amped. If you ever want a bigger lift, you can keep the theanine's smoothing effect and simply add caffeine on top (see How To Use).

What the evidence does and does not say

The caffeine and theanine combination is one of the best-supported pairings in the nootropic space. Multiple randomized controlled trials on the combination point to improved attention and accuracy on demanding cognitive tasks, with less of the jitter caffeine brings on its own. That is a strong evidence base by supplement standards.

The honest limit: the effects are real but modest. This can help support a sharper ordinary day. It will not rescue a bad one, and it is not a substitute for sleep. Individual response also varies, partly because caffeine metabolism is genetic. Treat the first bottle as a personal experiment rather than a guarantee.

Who it tends to suit

• Knowledge workers, students, developers, and writers, anyone doing sustained focused work.
• Coffee lovers who want the lift without the jitter.
• Meditators and gamers after calm, sustained alertness.
• Caffeine-sensitive people who still want some stimulant, since the theanine is there for exactly this.

Who it is not for

• Anyone avoiding stimulants entirely. This is a caffeine product; if you want calm without the stimulant, a standalone theanine is the better call.
• Anyone who needs caffeine late in the day, since the timing math does not work (see below).
• Anyone advised to limit caffeine (see Ingredients).

Start with a tolerance check. Everyone's caffeine tolerance is different. Take 1 softgel first and see how you respond before making it routine. More is not automatically better; the studied serving is one softgel (100 mg caffeine plus 200 mg theanine).

Timing is the thing most people get wrong. Caffeine's half-life is roughly 5 to 6 hours, meaning half of that 100 mg is still in your system 5 to 6 hours later. To protect your sleep, take it in the morning or early afternoon, ideally with or after food, and treat early-to-mid afternoon as a hard stop. Good sleep does more for focus than any capsule, so do not trade one for the other.

How to dose it

• 1 softgel is one studied serving. For most people that is all they need.
• Some take a second earlier-in-the-day dose on heavier days. If you do, count your total caffeine (including coffee) and mind the timing.

How to stack it

• Want more lift? Pair 1 softgel with a coffee. You keep the theanine's smoothing while raising the caffeine, which lets you dial in your own ratio.
• Want just calm with no stimulant? This is not the product for that; a standalone L-theanine is.
• Building a foundation? It slots alongside our choline, magnesium, and omega-3 basics with no redundancy.

Cycle it on purpose. Caffeine tolerance is real. Use it every single day and the effect quietly fades. Consider caffeine-free days, or a few days off every few weeks, to keep it working. Very few brands will tell you to periodically stop taking their product, but you get more out of less.

What to avoid

• Do not stack it with other caffeine sources (pre-workout, energy drinks, multiple coffees) without adding up your total daily caffeine.
• Contains coconut-derived MCT (a tree nut). Skip it if you have a coconut or tree-nut allergy.

• Third-party tested for identity, potency, and contaminants, which is independent verification rather than an in-house promise.
• Manufactured in the USA in a cGMP-compliant facility (current Good Manufacturing Practices).
• Non-GMO ingredients, with no fillers, no gluten, and no seed oils.
• Branded, standardized actives (AlphaWave® L-theanine, PurCaf® organic caffeine), traceable forms with their own quality documentation rather than unnamed bulk powder.

The strongest form of proof is a batch-specific Certificate of Analysis (COA) tied to the lot number printed on your bottle. If verifying a specific batch matters to you, note the lot number and request the COA from the manufacturer. If a brand cannot produce one, that tells you something.

A note on the branded forms

• AlphaWave® is a branded, standardized form of L-theanine.
• PurCaf® is organic caffeine naturally derived from green coffee beans rather than synthetic caffeine. It is here purely as the caffeine source; we make no weight-loss claims about green coffee bean extract.
• MCT oil (450 mg) is the softgel's clean lipid carrier, coconut-derived. At 450 mg this is a carrier, not a functional MCT dose.

Other Ingredients: Softgel capsule (gelatin, vegetable glycerin, purified water, turmeric [for color]), rice bran wax, sunflower lecithin.

Contains: Tree nuts (coconut).

Warnings (worth reading)

• Contains caffeine, 100 mg per softgel, roughly one cup of coffee. Factor it into your total daily intake.
• Not intended for those under 18, pregnant, or nursing.
• Consult your doctor before use if you have a heart condition, high blood pressure, an anxiety disorder, or take any medication, since caffeine can interact with certain drugs.
• Do not combine with other caffeine sources without accounting for total intake.
• Discontinue and consult a physician if you experience adverse effects such as a racing heart, marked anxiety, or trouble sleeping.
• Keep out of reach of children. Store in a cool, dry place.
