Science moves faster than we do, but we’re updating these lists as often as we can.
- Optimal Serum Selenium Concentrations Are Associated with Lower Depressive Symptoms and Negative Mood among Young Adults. (2015)
- Lower brain and blood nutrient status in Alzheimer's disease: Results from meta-analyses. (2017)
- Effects of Brazil nut consumption on selenium status and cognitive performance in older adults with mild cognitive impairment: a randomized controlled pilot trial. (2016)
