Im constantly feeling at stress and difficulty focusing on tasks. After some research, I found that L-theanine is known to help with stress relief and improve focus without causing me to feel sleepy, moderate dosage as recommended stress levels were lower these are particularly effective

Theanine Dosage for Anxiety and L-Theanine for Sleep

I’ve always struggled with anxiety and sleepless nights, so I decided to give L-Theanine capsules a go and already I am seeing results my anxiety, I started with a dosage of 200mg twice a day, and I noticed a calming effect within an hour. My anxiety levels have significantly decreased, and I feel more relaxed throughout the day. For sleep, I take an additional 200 mg of L-Theanine about an hour before bedtime. This routine has greatly improved my sleep quality. I fall asleep faster and enjoy deeper, more restful sleep without feeling groggy in the morning. The benefits of L-Theanine for both anxiety and sleep are remarkable. Vegishake’s capsules are of high quality, and I’m grateful for the positive impact they’ve had on my life.

I am someone who deals with stress and focus issues so I need L-Theanine capsules. The calming effect was noticeable without making me feel drowsy. I also combined it with L-Tyrosine from Vegishake.co.uk, for better results as they both work well together The combination of these amino acids has been noticeable for my mental clarity and stress levels. The L-Theanine helps with relaxation, while the L-Tyrosine boosts focus and cognitive function. I highly recommend this combo for anyone looking to enhance their mental well-being.
