Description

Elevate your daily wellness ritual with our synergistic blend of L-Theanine, Lemon Balm, and Chelated Magnesium Glycinate. Designed for those seeking a balanced, "zen" state of mind, this formula pairs the focused clarity of L-Theanine with the time-honored soothing properties of Lemon Balm. To ensure your body gets the most out of every capsule, we’ve included highly bioavailable Chelated Magnesium to support healthy muscle relaxation and a steady nervous system. Whether you're looking to take the edge off a demanding workday or gently unwind before bed, this supplement offers the perfect harmony of nature and science to help you stay composed, grounded, and ready for whatever comes next.

Why we made this product

We combined these three ingredients so that you aren't just addressing one part of stress; you are tackling it from mental (L-Theanine), emotional (Lemon Balm), and physical (Magnesium) angles all at once. L-Theanine (from Green Tea Extract) Promotes "Alert Relaxation": Known for increasing alpha brain waves, L-Theanine helps you feel calm and composed without the drowsy "fog" associated with other relaxants. Sharpens Focus: When paired with naturally occurring trace amounts of caffeine in green tea, it helps improve attention span and cognitive performance during stressful tasks. Balances the Jitters: It is often used to smooth out the "edge" or anxiety sometimes caused by caffeine or daily stressors. Lemon Balm Extract (4:1) Calms the Nervous System: A member of the mint family, Lemon Balm has been used for centuries to reduce feelings of nervousness and excitability. Supports Restful Sleep: By helping to lower cortisol levels and ease restlessness, it prepares the body for a more natural transition into sleep. Digestive Comfort: It is traditionally used to soothe "nervous stomach" or digestive upset triggered by emotional stress. Chelated Magnesium Glycinate High Bioavailability: Unlike cheaper forms (like Magnesium Oxide), the "chelated" glycinate form is highly absorbable and much gentler on the stomach. Muscle Relaxation: Magnesium is essential for proper muscle function, helping to relieve tension, cramps, and physical tightness. Neurotransmitter Support: It plays a critical role in regulating the body's stress response and supporting the production of GABA, a brain chemical that promotes calm.

The Benefits of our Advanced L-Theanine Complex


L-theanine (an amino acid found in tea) is famous for promoting "alert relaxation", combining with lemon balm (Melissa officinalis) acts as a complementary botanical that primarily targets the nervous system and GABA levels.

Both ingredients are known for reducing anxiety without the heavy sedation associated with pharmaceutical tranquilisers.

  • L-Theanine - Natural Form
    Naturally extracted L-Theanine has gained popularity in the supplement
    market due to a growing body of research surrounding its various health benefits. natural way to maintain focus during demanding tasks.
  • Lemon Balm Extract
    Lemon balm contains rosmarinic acid, which helps prevent the breakdown of GABA, a neurotransmitter that tells your brain to "calm down."
    While L-theanine doesn't make you drowsy, it helps the brain enter a state conducive to sleep. Lemon balm adds a mild sedative layer to this.
  • Chelated Magnesium Glycinate
    Adding chelated magnesium glycinate to your stack of L-theanine and lemon balm turns a "calm mind" supplement into a "total body relaxation" formula. While the first two focus on your brain's chemistry, magnesium targets the physical hardware of your nervous system and muscles.

Frequently Asked Questions about our Advanced L-Theanine Complex

  • What are the main benefits of taking an L-Theanine and Magnesium complex?

    Our L-Theanine Complex is a synergistic sleep and relaxation supplement designed to calm both the mind and body. L-Theanine promotes "alert relaxation" by increasing alpha brain waves, while Lemon Balm helps reduce the breakdown of GABA (your brain's natural "calm" chemical). Magnesium Glycinate completes the trio by supporting physical muscle relaxation and nervous system health, making it an ideal formula for those looking to manage daily stress and improve sleep quality naturally.

  • Will this L-Theanine supplement make me feel groggy the next morning?

    No. Unlike many pharmaceutical sleep aids or heavy sedatives, our L-Theanine and Lemon Balm formula is designed to support the body’s natural relaxation pathways. Because L-Theanine encourages a state of "wakeful relaxation" rather than forced sedation, most users find they wake up feeling refreshed and clear-headed, without the "brain fog" or grogginess often associated with traditional sleep supplements.

  • When is the best time to take an L-Theanine and Magnesium Glycinate supplement?

    For those using it as a natural sleep aid, we recommend taking your capsules 30–60 minutes before bedtime to help quiet a "busy brain." However, because L-Theanine provides calm focus without drowsiness, this complex can also be taken during the day to help manage periods of high stress or anxiety without affecting your productivity.

  • Why use Magnesium Glycinate instead of other forms of magnesium?

    We use chelated Magnesium Glycinate because it is widely considered the best form of magnesium for relaxation and sleep. It is highly bioavailable (meaning your body absorbs it easily) and is much gentler on the digestive system than cheaper alternatives like magnesium oxide. The addition of the amino acid glycine further supports the calming effect on the nervous system.

  • Can I take this L-Theanine complex for anxiety and stress during the day?

    Yes. This is a popular relaxation supplement for daytime use because L-Theanine is known for reducing the "jitters" and physical symptoms of stress while maintaining mental clarity. It helps take the edge off a stressful workday or a demanding schedule without the sedative effects that would interfere with driving or working.

  • Is the SSSportSupplies L-Theanine Complex habit-forming?

    No, our formula is non-habit forming. We use clean-label, natural ingredients like Lemon Balm extract and amino acids that support your body’s existing neurotransmitter functions. This makes it a safe, sustainable option for those looking for a long-term solution to support their mental wellbeing and sleep hygiene.

  • How long does it take to see results from this sleep and relaxation supplement?

    Many users notice a difference in their ability to relax and unwind on the very first night. However, for the Magnesium Glycinate and botanical extracts to fully support your nervous system, we recommend consistent daily use for at least 2–4 weeks. This allows your mineral levels to stabilise and provides cumulative support for your stress resilience.

  • Is this supplement vegan-friendly and free from fillers?

    Yes. At SSSportSupplies, we pride ourselves on a "Clean Label" philosophy. Our L-Theanine Complex is 100% vegan-friendly and manufactured in the UK to strict GMP standards. We ensure our capsules contain no unnecessary fillers, binders, or synthetic additives—just pure, high-strength active ingredients for maximum effectiveness.
