Learn all about L-Theanine™

L-theanine is a non-essential amino acid. Amino acids are the building blocks for proteins and play various roles in metabolism in the body.
 L-theanine was discovered in the tea leaf (Camellia sinensis) a few decades ago. L-Theanine can increase your nervous system's level of various neurotransmitters such as GABA and dopamine, resulting in many potential benefits on our minds, mood, and emotional levels.

L-Theanine™ may assist with: 

  • Sleep cycle improvement
  • Relaxation support
  • Mood support
  • Mental focus

Studies and Trials for L-Arginine

"Anti-Stress, Behavioural and Magnetoencephalography Effects of an L-Theanine-Based Nutrient Drink: A Randomised, Double-Blind, Placebo-Controlled, Crossover Trial."

White DJ, de Klerk S, Woods W, Gondalia S, Noonan C, Scholey AB. Anti-Stress, Behavioural and Magnetoencephalography Effects of an L-Theanine-Based Nutrient Drink: A Randomised, Double-Blind, Placebo-Controlled, Crossover Trial. Nutrients. 2016 Jan 19;8(1):53. doi: 10.3390/nu8010053. PMID: 26797633; PMCID: PMC4728665.

 "L-theanine (γ-glutamylethylamide) is an amino acid found primarily in the green tea plant. This study explored the effects of an l-theanine-based nutrient drink on mood responses to a cognitive stressor. Additional measures included an assessment of cognitive performance and resting-state alpha oscillatory activity using magnetoencephalography (MEG). Thirty-four healthy adults aged 18–40 participated in this double-blind, placebo-controlled, balanced crossover study. The primary outcome measure, subjective stress response to a multitasking cognitive stressor, was significantly reduced one hour after administration of the l-theanine drink when compared to placebo. The salivary cortisol response to the stressor was reduced three hours post-dose following active treatment. No treatment-related cognitive performance changes were observed. Resting-state alpha oscillatory activity was significantly greater in posterior MEG sensors after active treatment compared to placebo two hours post-dose; however, this effect was only apparent for those higher in trait anxiety. This change in resting-state alpha oscillatory activity was not correlated with the change in subjective stress response or the cortisol response, suggesting further research is required to assess the functional relevance of these treatment-related changes in resting alpha activity. These findings further support the anti-stress effects of L-theanine."

When should I take Vitamin Supplements?

It is best to take supplementation as directed. As a rule with breakfast, lunch and dinner is best. Take supplements that assist with sleep 20 minutes before bed. Be careful not to take high amounts of B-vitamins or stimulants before bed. In addition, if a condition continues for an extended time, a week or more, or if you feel severe pain, see your healthcare professional immediately.

About us

Our Products

Our standards are the highest in the industry. We use "00" Vegetarian Capsules with no additives, fillers or binders. Always use grade A Superior or above quality herbs, minerals and oils. We believe you will not find better quality and pricing. Take time to see what, how much and most importantly the quality of what you purchase. Just as important our herbs are never stored in a warehouse in heat or sever conditions.


The majority of our products contain 100mg of herbs and minerals. Take a moment and think of the cost of a 250 mg product and multiply it times 4. The savings range form 50% to 100% savings. Far too often, advertising drives the buyer and not the quality and quantity of the product. We guarantee our products for 30 days and as long as they have not been exposed to external conditions.

When to see a medical professional.

The diagnostic tools of modern medicine are impressive. Far to often overmedicating can cause further health issues. However, seeing a trained and licensed professional has its place, especially in diagnostics. Remember as medical professionals we are your employees. You have the right to ask as many questions and dictate your healthcare.
