Description

OstroVit L-Theanine is a vegan dietary supplement which contains L-Theanine and inulin. Substances are recommended for people who live in constant tension, have problems with learning and concentration.

What is l-theanine, and when is it worth reaching for it?

L-theanine is a biologically active non-proteinogenic amino acid which occurs naturally in tea leaves, represents about 1-2,5% of their dry weight and gives the tea infusion a distinctive umami flavour. Thanks to the fact that the chemical structure of L-theanine is very similar to the structure of glutamine, it is able to overcome the blood-brain barrier. In effect it can have a direct influence on your cognitive functions, e.g. may lower anxiety, support learning, as well as reduce physical fatigue after an intensive workout.

Properties of the ingredients contained in OstroVit L-Theanine VEGE:

  • BRAIN SUPPORT – The product can support cognitive capabilities, which manifests itself with faster memorizing and better concentration.
  • FASTER REGENERATION – L-theanine can reduce physical fatigue so it is perfect for athletes who want to extend the duration of the training and enjoy faster regeneration.
  • STIMULATION OF IMMUNITY – L-theanine metabolite activates gamma delta T cells which serve as a significant element of the immunological system.
  • VEGAN COMPOSITION – The dietary supplement is hidden in a vegan capsule which is free from animal-origin substances. Thanks to this, you can use it even if you lead a vegan lifestyle.

SUGGESTED USE: Take 1 serving (1 capsule) daily with a meal.

Do not exceed the recommended daily dose. Do not use the product as a substitute (replacement) for a varied diet. Recommended are a balanced diet and a healthy lifestyle. Do not ingest if you are allergic to any of the ingredients. Do not consume the product by children, pregnant or nursing women. Keep out of the reach of children.
