Many people turn to a comforting cup of tea when we’re feeling anxious or stressed. This may be due to L-Theanine, an amino acid that is commonly found in green tea. It was discovered as a constituent of green tea in 1949 and in 1950 was isolated from gyokuro leaves. It is also the L-Theanine that provides a unique savory (umami) flavor to green tea infusions. As well as green tea, L-Theanine can also be found in black, and white teas from the Camellia sinensis plant. L-Theanine is an amino acid. Amini acids are classified as the building blocks of protein and are needed in several internal functions of the body. They are generally classified as “essential” or “non-essential”, with essential amino acids meaning they cannot be manufactured by the body and must be supplied in the diet to maintain good all-round health. L-Theanine however does not fall within either the essential or non-essential categories because it is not common in the diet and cannot be made by the body. It has a chemical structure similar to a neurotransmitter type of amino acid, glutamine, which naturally occurs in the body. L-Theanine is able to cross the blood brain barrier and can influence brain wave activity. Solgar L-Theanine 150 mg is to be taken twice daily, 1 capsule, and comes in an easy to absorb vegetable form. All Solgar products meet our industry recognized “Gold Standard” for excellence.

I feel calmer, more level-headed, and like I can handle whatever the day throws at me - it’s effective.That said, Solgar feels expensive for what it is. The quality seems solid, though: a lot of cheaper alternatives have bulking agents, and I don’t often see those in Solgar products. Not sure whether that’s a big deal, but it’s something I appreciate. ### ⭐⭐⭐⭐⭐ Good company for quality items. *by on Reviewed in the United Kingdom 29 November 2025* Quick delivery. From a good company, unable to find this anywhere else. Not used yet but will be shortly. Reliable service for quality goods. ### ⭐⭐⭐⭐⭐ Can't recommend these enough *by on Reviewed in the United Kingdom 15 August 2017* I bought this after reading a lot of very positive reviews here and elsewhere. When it arrived I took 2 capsules and it gave me a headache so I reduced my following doses to just one capsule and haven't had a headache since. The big benefit came when I changed the way I took it. I read online that some people empty the capsule under their tongue and let the powder dissolve there. The amino acid is water soluble and as it dissolves the underside of your tongue absorbs it and it gets into the blood stream much quicker. I tried this and it definitely works better. I feel the effects much faster and the effect of just one capsule is more than enough to keep my anxiety away for 4hours or so. I also don't need to worry about taking it on an empty stomach. I take one before I go to work in the morning and combined with the caffeine in a strong coffee I am focussed, calm and productive. Can't recommend these enough. ## Frequently Bought Together - Solgar L-Theanine 150 mg - 60 Vegetable Capsules - Promotes Relaxation - Non-GMO, Vegan, Kosher & Gluten Free - 60 Servings - Solgar GABA 500 mg, 100 Vegetable Capsules - Relaxation & Nervous System Support - Amino Acid - Non-GMO, Vegan, Gluten Free, Dairy Free, Kosher - 100 Servings - Solgar Magnesium Citrate, 120 Tablets - Promotes Healthy Bones - Supports Nerve & Muscle Function - Non GMO, Vegan, Gluten Free, Dairy Free, Kosher - 60 Servings, Standard Packaging --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/47990742-solgar-l-theanine-150-mg-vegetable-capsules-pack-of-60](https://www.desertcart.jp/products/47990742-solgar-l-theanine-150-mg-vegetable-capsules-pack-of-60) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-22*
