- Product Information
The powerful combination of Theanine and Lemon Balm continues to be a popular choice with customers who are looking to support their overall wellbeing. Known for its relaxing properties, Lemon Balm derives from the mint family. L-theanine, meanwhile, is one of the main active ingredients in tea, which is said to make this beverage uniquely calming and soothing. Discover more ways to support relaxation here.
Two of our high-performance Theanine and Lemon Balm capsules contain the same 200mg of L-theanine – found in our original supplement – but with the addition of 600mg of Lemon Balm (Melissa). To L-theanine and Lemon Balm, we added biotin for the normal function of the nervous system and normal psychological function, as well as pantothenic acid for normal mental performance.
Our Theanine and Lemon Balm Complex makes the perfect partner to Valerian, for the temporary relief of sleep disturbances and mild anxiety.
We’ve chosen to supply our Theanine and Lemon Balm complex in capsules - not tablets – since this material is better for fast-release formulas.
Our supplement comprises the best raw materials sourced from reliable and responsible suppliers. Many companies choose to sell the less active D-form of L-Theanine, extracted from tea. However, we insist on using the pure L-Theanine form in our formula. Before being manufactured and packaged in UK factories working to Good Manufacturing Practice (GMP), our raw material receives rigorous quality checks, ensuring it meets the strictest EU regulations on contaminants.

"Calming But Unclear If It Contains Caffeine?"
By Anonymous

This certainly seems to have calming effects in the day but I've suffered from insomnia after taking it in tge evening, which may or may not be related to the producing as I struggle with sleep generally.
This prompted me to check the ingredients though. The product description says: "Our supplement comprises the best raw materials sourced from reliable and responsible suppliers. Many companies choose to sell the less active D-form of L-Theanine, extracted from tea. However, we insist on using the pure L-Theanine form in our formula."
However the ingredients are listed as: "Green Tea (Camellia sinensis) Leaf Extract, Lemon Balm (Melissa officinalis) Leaf Extract, Capsule Shell (Hydroxypropyl Methylcellulose), Brown Rice Flour, Anti-caking Agents (Stearic Acid & Silicon Dioxide), Pantothenic Acid (Calcium Pantothenate), Folic Acid, Biotin."
It'd be great if someone from Natures Best could explain this discrepancy please? As I don't want to consume caffeine before bed.

Thank you for taking the time to leave a review. I am sorry to hear that you feel as if the product is causing you issues with your sleep, this certainly isn't something we would expect.
Our product uses L-Theanine from tea, rather than D-Theanine from tea. Therefore, the source of our L-Theanine is still from tea (green tea in particular). However, it does not contain caffeine. It is a legal requirement to state if it does contain caffeine but not to declare that it is decaffeinated.
I have contacted you separately to discuss this further.

"Certainly Worth Trying"

Having read a few nutritional books theanine came as recommended for calming a busy mind and help sleepless nights. I also take ashwaganda and magnesium for the same thing but have long forgotten the best time to take these supplements. I do not find anything helps me sleep better, sometimes I do, sometimes not irrespective of what I take. But I’m convinced theanine and ashwaganda help to keep the daily pressures low.

Thank you for taking the time to leave a review. As with the majority of our products, this should be used daily for at least three months before the effects are assessed. I have contacted you directly to discuss this further.
