Reduces the stress response.

★★★★★Kari O.

Helped me with anxiety, I couldn't recommend it more if you are trying to avoid traditional medicine. High quality, they could definitely improve the packaging so that it is either smaller or the bottles are actually full instead of wasting so much plastic. Additionally, the ingredients are scientifically tested.

Description

Product Overview

Life Extension Theanine XR Stress Relief is a high-quality dietary supplement in tablet form containing 400 mg of L-theanine per dose. The tablet pack contains 30 tablets, making it easy to include in your daily routine. Life Extension is an American brand with a solid background in scientifically based supplement development. The company's philosophy is based on combining thorough research with quality ingredients to create products that are reliable and safe to use. What sets Theanine XR Stress Relief apart is the patented extended-release technology that allows the L-theanine to be gradually released throughout the day, providing a steady supply of the amino acid over time. The product is also free from gluten, GMOs, and suitable for vegetarians, making it a flexible choice for many different lifestyles.

Active Ingredients & Science

The active substance in the product is L-theanine, here in the form of AlphaWave® Theanine XR — a patented extended-release variant. L-theanine is an amino acid often extracted from green tea and has the ability to cross the blood-brain barrier. The gradual release ensures the amino acid is supplied to the body in a controlled manner, distinguishing this product from regular supplements where the effect may come in a rapid peak. In addition to L-theanine, the product also contains calcium from dicalcium phosphate, which contributes to the body's mineral balance and is easily absorbed.

Benefits & Uses

  • Provides a steady and long-lasting supply of L-theanine thanks to advanced extended-release technology.
  • Suitable for individuals who want to integrate L-theanine into their daily routine in a simple and practical way.
  • Especially suitable for those living stressful or intense days and seeking support for mental balance.
  • Can be used during work or study to promote a sense of calm without causing drowsiness.
  • Gluten-free, non-GMO, and vegetarian, broadening the scope of use and making the product accessible to many.
  • Only one tablet per day is needed due to the extended release, simplifying dosing.

Usage & Dosage

The recommended dose is one tablet daily, corresponding to 400 mg of L-theanine. The tablet can be taken with or without food, but for optimal absorption, it may be beneficial to take it with a meal. The extended release means you receive a steady supply of the amino acid throughout the day without needing multiple doses. The product can be combined with other supplements if desired, but it is always advisable to consult a healthcare professional if uncertain or when using medications.

Life Extension places great emphasis on quality at every stage of production. The products are manufactured under strict controls and adhere to high standards for purity and safety.
