The Power of Sleep: How Black Seed Extract Supports Immunity and Reduces the Stress Response
A recent study, published in Frontiers in Nutrition, delved into this intricate connection and explored the potential of black seed extract in addressing these health concerns. The study, a randomised, double-blinded, placebo-controlled clinical trial, involved 150 volunteers aged 25 to 65 years who experienced significant stress and self-reported sleep issues over the previous four weeks.
Thymoquinone (TQ) is a naturally occurring compound found in the seeds of Nigella sativa, also known as black cumin or black seed. TQ is a bioactive phytochemical with various potential health benefits and has been studied extensively for its medicinal properties.

In this study, participants were given a daily dose of 200mg black seed extract, containing 5% thymoquinone, for a duration of 90 days. The results were remarkable.
Approximately 62% of participants reported beneficial effects after taking just one dose. By day 7, around 70% reported higher satisfaction of quality of sleep, with this number increasing to 79% by day 14. The most common feedback included reductions in sleep disturbances and improvements in overall sleep quality.
Detailed analysis of the data revealed significant improvements in various sleep parameters among participants taking the black seed extract. These improvements included reductions in sleep latency, increased sleep duration, enhanced overall sleep efficiency, decreased sleep disturbance, and reduced daytime dysfunction. In contrast, changes in sleep parameters were not significant in the placebo group.
Moreover, the study also observed significant reductions in stress parameters among participants taking the black seed extract. This was associated with improved sleep scores and lower cortisol levels, indicating a more relaxed state.
One of the most notable findings of the study was the positive impact of black seed extract on immune function. Participants experienced significant increases in immunoglobulins, CD4+ cells, CD4/CD8 ratio, as well as the number of certain white blood cells, especially lymphocytes and monocytes. These findings suggest that black seed extract not only promotes better sleep and reduces stress but also strengthens the body’s immune response.
In conclusion, this controlled study provides compelling evidence for the efficacy of black seed extract for modulating the stress-sleep-immunity axis. While the mechanism is not (as yet) understood, it is clear that by alleviating stress, improving sleep quality, and boosting immunity, black seed extract offers a holistic approach to enhancing overall health and well-being.
Incorporating black seed extract into your daily routine may offer significant benefits, especially for those experiencing stress-related sleep disturbances. However, as with any supplement, it’s essential to consult with a healthcare professional before starting a new regimen.
With further research and understanding, black seed extract appears to be emerging as a valuable tool for many common health issues. A few are highlighted here: promoting better sleep, reducing stress, and strengthening immunity for a healthier, happier life.
Note: This study used a 200mg extract from black seed oil with a TQ content of 5.12%. House of Health BLAQ® is verified to contain 1.97% TQ.
