Description
Product overview
OstroVit L-Theanine is a carefully formulated food supplement supplied in easy-to-swallow capsules, with 90 capsules in each container. Each capsule provides a 200 mg dose of the amino acid L-theanine, a substance that occurs naturally in green tea and is valued for its unique quality of fitting into a daily routine without the need to consume large quantities of tea. OstroVit is a European brand with strong roots in quality awareness and transparency. The company's philosophy is based on offering pure, carefully tested products with clear ingredient information and a focus on ease of use. With OstroVit L-Theanine, you get a practical and reliable supplement designed for those who want a simple and precise dose of L-theanine in capsule form.
Active ingredients & science
The main active component in the product is L-theanine, a free amino acid with a unique chemical structure that enables it to cross the blood–brain barrier. The combination of these ingredients makes the product versatile, with a focus on both mental wellbeing and digestive health.
Benefits & uses
- Each capsule contains a high, consistent dose of L-theanine, equivalent to several cups of green tea, making dosing simple and precise.
- The capsules are easy to take and incorporate into daily routines, with no preparation or flavouring required.
- The product is free from common allergens and is entirely vegan, making it suitable for people with different dietary preferences and restrictions.
Use & dosage
The recommended dose is one capsule per day, equivalent to 200 mg of L-theanine. The capsule can be taken with or without food, although taking it with a meal may be beneficial for optimal absorption. L-Theanine can also be combined with caffeine for those seeking balanced alertness without overstimulation. It is important not to exceed the recommended dose. One container provides a month's supply when taken daily.
