After 16 months of daily L-theanine supplementation, the author experienced subtle but positive effects. They reported feeling calmer and more focused, with reduced anxiety and improved sleep quality. These benefits were particularly noticeable during stressful periods. While acknowledging the possibility of placebo, the author found the effects consistent enough to continue taking theanine, viewing it as a beneficial addition to their routine for promoting a general sense of well-being. They emphasized the subjective nature of their experiment and encouraged others to research and experiment themselves.
Over a period of sixteen months, the author, Michael Hoffman, meticulously documented a self-experiment involving the regular ingestion of L-theanine, an amino acid commonly found in green tea and purported to have relaxing and focus-enhancing properties. Driven by a desire to ameliorate feelings of anxiety and enhance cognitive function, Mr. Hoffman embarked on a rigorous and quantified exploration of theanine's subjective effects. His methodology involved consuming varying dosages of theanine, typically in capsule form, and meticulously recording his observations in a detailed spreadsheet. These observations encompassed a wide range of parameters, including mood, anxiety levels, sleep quality, and perceived cognitive enhancements, such as improved focus and creativity.
Throughout the experiment, Mr. Hoffman diligently tracked his daily theanine intake, alongside contextual factors such as caffeine consumption, sleep patterns, and general life stressors, to account for potential confounding variables. He employed a subjective rating scale to quantify the perceived impact of theanine on his mental state, enabling him to discern subtle trends and patterns over time. The author's analysis of the accumulated data revealed a nuanced and complex relationship between theanine dosage and its subjective effects. While he reported experiencing notable reductions in anxiety and improvements in sleep quality at certain dosage levels, he also observed diminishing returns and even occasional adverse effects, such as increased lethargy and decreased motivation, at higher doses.
Mr. Hoffman's detailed account of his personal experience with theanine provides a valuable, albeit anecdotal, perspective on the potential benefits and drawbacks of this dietary supplement. He emphasizes the importance of individual responses to theanine and advocates for a personalized approach to dosage and consumption, acknowledging that the optimal regimen may vary significantly from person to person. His meticulous record-keeping and transparent reporting methodology contribute to the credibility of his findings, offering a compelling narrative of self-discovery and a nuanced exploration of the potential cognitive and emotional benefits of L-theanine supplementation. While acknowledging the limitations of a self-experiment, Mr. Hoffman encourages further research into theanine's effects, suggesting that his findings could serve as a valuable starting point for more rigorous scientific investigations. He concludes by recommending a cautious and personalized approach to theanine supplementation, emphasizing the importance of careful self-monitoring and dose adjustment to maximize potential benefits while minimizing the risk of adverse effects.

HN users discuss the original poster's (OP) self-experiment with theanine, expressing skepticism about the subjective nature of the reported benefits and the lack of a control group. Some users suggest the placebo effect may be at play, while others question the long-term effects of daily theanine use. Several commenters share their own experiences with theanine, with varying results, some finding it effective for anxiety relief and focus, others experiencing headaches or no noticeable effects. The potential for individual variation in response to theanine is also highlighted. There's also discussion around the dosage used by the OP and whether combining it with caffeine negates any benefits. Finally, some users request more rigorous data and controlled studies to validate theanine's purported effects.
The Hacker News post "My 16-month theanine self-experiment" generated several comments discussing the author's experience with the supplement, along with broader considerations regarding its use and efficacy.
Several commenters shared their own experiences with theanine, some mirroring the author's positive findings. One user described feeling calmer and more focused after taking theanine, particularly in social situations. Another mentioned using it alongside caffeine to mitigate the latter's jittery effects, corroborating a common use case mentioned in the original post. However, not all experiences were positive. One commenter noted experiencing headaches after taking theanine, advising caution and suggesting starting with a lower dose.
The discussion also delved into the scientific aspects of theanine. One commenter questioned the methodology of the self-experiment, highlighting the lack of a control group and the potential for placebo effects. This sparked a small thread discussing the limitations of self-experimentation and the importance of rigorous scientific studies for drawing definitive conclusions. Another user requested more details about the author's dosage and timing, emphasizing the importance of such information for others considering trying theanine.
A few commenters offered alternative suggestions for managing stress and anxiety, including mindfulness meditation and exercise. One commenter specifically cautioned against relying solely on supplements and advocated for a holistic approach to well-being. Another user shared a link to Examine.com, a website known for its evidence-based analysis of supplements, providing a resource for further research on theanine.
Finally, some comments focused on the subjective nature of supplement effectiveness. One user pointed out the variability in individual responses to supplements, highlighting the importance of personal experimentation to determine what works best. Another commenter echoed this sentiment, adding that factors like diet, lifestyle, and genetics can influence the effectiveness of supplements.
