L-theanine is recommended to be used approx. 1 hour in the evening before going to sleep or before a stressful situation. Nowadays, it is also popular to add L-theanine to coffee, which balances and reduces the side effects of caffeine. Natural L-theanine is suitable for daily use. The capsule is small and easy to swallow.

Natural L-theanine is structurally similar to the brain's own neurotransmitters glutamate and gamma-aminobutyric acid (GABA). The use of L-theanine is often associated with better concentration, calmness, and relaxation.

Recommended uses of L-theanine:

  • Consumed with liquid one hour before bedtime

  1. English


    Hyvä tuote, yhdessä magnesiumin kanssa rauhoittaa ja rentouttaa ja helpottaa nukahtamista sekä parantaa unen laatua. Toimii mainiosti kahvin kanssa.
    Auttaa myös adhd-oireiluun jos on huono päivä kun ahdistaa ja kiristää niin nämä ovat olleet iso apu.

Questions and answers about CBDa and CBD in general

What is CBDa?
What are cannabinoids?
  • Cannabinoids are a group of compounds originally found in hemp, but they refer to all compounds associated with endocannabinoid system (Z. Fisar. 2009; AC. Howlett et al. 2002; DM. Lambert et al. 2005). These include phytocannabinoids, ie external cannabinoids, endocannabinoids, i.e. internal cannabinoids, and synthetic laboratory produced cannabinoids. More than a hundred different types of external cannabinoids have been found in hemp. In total, hemp contains about 489 different compounds (N. Happyana et al. 2013).
Is CBDa the same thing as CBD?
  • CBDa (cannabidiol acid) is a precursor to CBD (cannabidiol) as it is in fresh hemp.
  • CBDa is transformed into CBD by time and heat.
What is CBD oil?
  • CBD oil is not intoxicating at all because it is usually made from industrial fiber or oil hemp varieties containing less than 0.2% THC, which produce more CBD and other cannabinoids than THC.

  • CBD oil is a mixture of cannabinoid-rich hemp extract and a carrier oil (such as MCT oil from coconut)
  • The cannabinoid-rich extract is mixed with various vegetable fats that act as a carrier for the active ingredients to facilitate dosing and absorption.
  • CBD oil is sold in pipette bottles that facilitate the taking of suitable dosage sizes and is used 1-12 drops at a time depending on the intended use.


Can CBD be used together with medications?
  • We do not recommend the use of calcium channel blockers and anticoagulants in combination with CBD products, as some studies suggest that high levels of CBD may affect the efficacy and absorption of certain drugs. Further research is needed on drug interactions. More information on drug interactions can be found here >
Should CBD products be stored in the refrigerator?
  • Oil-based CBD oils are best kept dry and cool.
  • We recommend storing opened products at room temperature, so that moisture does not form inside, for example from the refrigerator.

  • CBD cosmetics are best stored in a dry and cool place, protected from sunlight
How are CBD oils different?
  • There are differences in the strengths and cannabinoid concentrations of CBD oils. CBD concentrations are generally described as either percentages or milligrams.
  • In addition to cannabidiol, raw extracted CBD-A/CBD oils contain cannabidiol acid (CBD-A), which is a precursor to CBD.
  • In addition to CBD, CBG oils also contain added CBG and CBN extract. Read more about CBG or cannabigerol and CBN or cannabinol.


Is CBD safe for pets?
  • It is also safe to give CBD to domestic animals.
  • The endocannabinoid system (ECS), which is affected by CBD and other cannabinoids, is found in almost all animals, except protozoa and insects.
  • Because of ECS, even your pets benefit from using CBD oil.
  • Finding the right dose for your pet may take time and observation. Take into account the condition and weight of your pet. Order CBD products for animals from a reliable seller.
  • The instructions are not an official recommendation, so we recommend that you consult a veterinarian before starting to use CBD to make sure it is safe.
  • Read more about CBD dosing for dogs and mammals.
How much CBD can I give my dog?
  • There is as yet no official standard for the administration of CBD to dogs or pets.
  • Although your dog’s weight will not always correlate with how much CBD is needed, it is a good starting point for determining the appropriate dose.
  • We recommend starting with the lowest dose of 1 mg CBD for every 5 pounds of body weight.
  • Sometimes conditions require higher doses of CBD. If your dog's condition is more severe, you may want to consider a higher dose such as 2-5 mg CBD / 5 kg body weight once or several times a day. Read more about dosing from here .
  • Determining the correct dose of CBD for your dog may take some time and require monitoring. Always consider the weight and condition of your dog, and get your CBD product from a reliable vendor.
  • These instructions are not an official recommendation, so we recommend that you contact your veterinarian before use to confirm this.
Can CBD products have intoxicating effects??
  • Products made from CBD and CBDa have no intoxicating effects at all. The main intoxicating compound in hemp and medical cannabis is THC (tetrahydrocannabinol).
  • CBDa products are made from industrial useful hemp that does not contain narcotic amounts of THC (always below the EU approved 0.2% limit).
  • THC is only found in varieties specially bred for medicinal cannabis.


Are CBD products free of contamination and heavy metals?
  • All products sold in the online store have been tested to be free of heavy metals and other possible contamination.
  • Each product is analyzed in a third-party laboratory to ensure purity.
