L-Theanine Overview

L-Theanine is a compound that has received much attention in recent years due to its inclusion in many all natural herbal supplements for treating anxiety and depression. Typically derived from green tea, L-Theanine is presented as being capable of relieving common symptoms of anxiety without the side effects that often occur during the use of prescription anti-anxiety supplements. L-Theanine is naturally found as a non essential amino acid; it is believed to be beneficial for promoting an increased production of dopamine within the body, and increased levels of dopamine typically correlate to improved overall feelings of happiness and uplifted moods. Additionally, this amino acid is said to increase GABA production, which should offer further anti-anxiety benefits.

L-Theanine The Product Details

L-Theanine

L-Theanine has been tested in clinical studies, but these studies have been too few and too small to solidly state the claimed benefits of L-Theanine to be true. Additionally, scientists warn that the claim of “no side effects” of supplementing with L-Theanine may also only still be able to stand because of the general lack of extensive research performed on this compound. However, at the same time, the few studies that have been done indicate that supplementing with 1000mgs of L-Theanine effectively increased feelings of relaxation about 30 to 40 minutes after being ingested. Since feelings of relaxation should counterbalance feelings of anxiety, the claim that L-Theanine can reduce feelings of anxiety seems to stand true, at least according to this small study.

Strengths of L-Theanine

  • This amino acid can be naturally extracted from various plants, including green tea.
  • L-Theanine may offer benefits for improving focus and mental clarity, as well as reducing the feelings of anxiety.
  • Some studies have been conducted on this compound.

Weaknesses of L-Theanine

  • Studies on this compound have been few and small.
  • A high dosage of this compound must be taken in order to achieve the promoted relaxation benefits.

L-Theanine The Bottom Line

L-Theanine sounds like a promising natural way to counteract feelings of anxiety and depression, but further research needs to be conducted before this compound can be fully endorsed as such. Additionally, the high dosage used in the stated clinical study means that consumers should be wary of any supplements that claim to provide the promised benefits of L-Theanine within a proprietary blend, since such benefits appear to only be achievable at high concentrations, and proprietary blends typically do not contain high concentrations of any one ingredient.

Good quality products should take a complete approach to both symptom resolution and improving the quality of your life. They should restore and balance healthy neurological function and provide the nutritional support your body needs for overall well-being.
