This study explored how a selenium-containing compound, SeI, impacts depression-like behavior in mice. During behavioral tests, this compound reduced immobility, signaling an antidepressant-like effect without affecting movement.

Notably, blocking specific serotonin receptors changed the results, indicating the serotonergic system's involvement. With a low potential for side effects, SeI shows promise for developing new treatments for major depressive disorder (MDD).

However, it's important to note this research was conducted in mice, so effects in humans remain unconfirmed.

Selenium compound alleviates depression symptoms
We observed the effects of a synthetic compound called 2-phenyl-3-(phenylselanyl)benzofuran (SeBZF1) on mice suffering from sleep deprivation-induced depression.

The study involved assessing behavioral changes after administering SeBZF1, alongside a known antidepressant, fluoxetine.

Remarkably, SeBZF1 not only reversed depressive-like behaviors and memory deficits but also reduced oxidative stress in the brain.

This research suggests that SeBZF1 could be a promising avenue for treating sleep-related neurobehavioral issues.

We explored the effects of a new compound, CFSePB, to see if it could help alleviate depression-like symptoms in mice. Using several tests like the forced swimming test, we looked at how this selenium-rich compound influenced the serotonergic and noradrenergic systems.

While the results indicate that CFSePB has potential antidepressant-like effects, the study is still in its early stages. More research is needed to fully understand its efficacy and how it may be applied to human treatments for depression.

Depression alleviated
6 people found this helpful
This selenium from IHerb is remarkable. As someone with a goitre, I take it alongside iodine. Since I started, my depression has vanished, and I feel fantastic. It assists with iodine absorption, and I've noticed fewer colds. I take 200 mcg daily for myself and 100 mcg for my daughter each morning with breakfast. Overall, I feel a boost in my health.

Everyone recommends selenium, so I decided to give it a try when I was experiencing poor sleep, fatigue, a low mood, and depression. Following the instructions, I started with small doses and did not face any adverse effects. The benefits I gained were tremendous: I felt energised, my mood improved, and my sleep quality enhanced significantly. Only positive experiences!

PHDI linked to reduced depression
We studied the connection between adherence to the Planetary Health Diet Index (PHDI) and depression using data from the National Health and Nutrition Examination Survey. Our analysis revealed a strong negative correlation between higher PHDI scores and the likelihood of experiencing depression.

Specifically, individuals in the highest quartile of PHDI showed significantly reduced depression risks. Vitamins and nutrients like Vitamin C, Fiber, and Selenium played notable roles in this relationship. Essentially, the data suggests that a diet aligned with sustainable practices may help protect mental health.

Selenium supplementation shows promise
We examined how selenium-enriched fermented goat milk, made from Lactobacillus paracasei, impacts depression in mice exposed to chronic stress. The findings revealed that this treatment significantly reduced depressive behaviors and helped counteract inflammation and glucocorticoid resistance.

Additionally, we observed improvements in oxidative stress within critical brain areas. Changes in gut bacteria composition further supported the treatment’s potential effects. Overall, these insights lay a foundation for future probiotic supplements aimed at supporting mental health in depressed individuals.

Revitalised energy
After giving birth, I often felt exhausted and lethargic. After completing a course of selenium, I felt revitalised, and my depression noticeably lessened. I no longer felt the urge to cry.

Avoids postpartum depression
Selenium is an exceptional supplement that I chose based on a kinesiological test. I took it alongside my prenatal vitamins during the second and third trimesters when the demand for trace elements increased significantly. Selenium aids in preventing postpartum depression, facilitates healthy placental aging, and prepares the body for childbirth. I consumed two tablets daily from the seventh month of pregnancy, a dosage my body required. Consequently, I experienced a natural labour without medication, which is quite rare nowadays. The capsules were easy to swallow despite their characteristic odour.

Selenium compound shows antidepressant potential
We investigated the potential of a selenium-based compound, 1-(phenylselanyl)-2-(p-tolyl)indolizine (MeSeI), as an antidepressant in male Swiss mice.

By using tests like the tail suspension and forced swim tests, we observed that MeSeI significantly reduced immobility time at certain doses, indicating an antidepressant-like effect.

The results suggest that the serotonergic system plays a key role in this effect, making MeSeI a candidate for future depression treatments. However, it’s worth noting that there was no change in locomotor activity, indicating that MeSeI's effects are specific to depression-related behaviors.
This study explored how a selenium-containing compound, SeI, impacts depression-like behavior in mice. During behavioral tests, this compound reduced immobility, signaling an antidepressant-like effect without affecting movement.

Notably, blocking specific serotonin receptors changed the results, indicating the serotonergic system's involvement. With a low potential for side effects, SeI shows promise for developing new treatments for major depressive disorder (MDD).

Selenium's uncertain effects on depression
We explored the relationship between selenium and depression through a thorough review of existing observational and interventional studies. Despite examining 20 studies, we found no clear difference in selenium levels between those with depression and healthy individuals.

Additionally, we didn’t observe a significant link between selenium levels and depression scores. However, it’s noteworthy that higher selenium intake appeared to lower the risk of postpartum depression, and selenium supplementation showed promise in alleviating depressive symptoms.

While these hints suggest selenium might offer protective benefits, more research is needed to really understand its role in treating depression.

Selenium mitigates infertility-related depression
We analyzed data from 4,949 women to explore whether selenium intake helps alleviate depressive symptoms linked to infertility. Our findings revealed that women experiencing infertility faced a 54% higher risk of depression.

Interestingly, those consuming at least 55 μg of selenium tended to have a lower risk of depressive symptoms. We noted that selenium significantly moderated the relationship between infertility and depression, but not at levels above 55 μg.

Ultimately, while selenium shows potential benefits, it isn't a cure-all, especially for those with infertility struggles.
