Summary
Karen Nicol, a family nurse practitioner, provides a comprehensive overview of low-dose and microdose lithium for mood, cognitive function, and suicide prevention. She addresses the stigma around lithium, explaining that pharmaceutical doses for bipolar disorder (1200-1500mg) are vastly different from the microdoses (0.3-10mg) showing benefits in clinical research. Nicol reviews landmark studies including a double-blind trial showing 300 micrograms of lithium daily prevented cognitive decline in Alzheimer's patients over 15 months, a 2020 review of 6500 bipolar patients showing 49% reduced dementia risk with lithium treatment, and a 2021 meta-analysis of 113 million people showing areas with higher groundwater lithium have fewer suicides and mental health admissions. She also covers lithium for treatment-resistant depression, substance use disorder (50% decrease in opiate use, 99% decrease in benzodiazepine use), and recommends specific third-party tested brands including Swanson and Life Extension products.
Key Points
- Pharmaceutical lithium for bipolar is 1200-1500mg daily; microdose lithium orotate is 0.3-10mg — vastly different
- Double-blind trial: 300 micrograms daily prevented cognitive decline in Alzheimer's patients over 15 months while placebo group worsened
- 2020 review of 6500 bipolar patients on lithium showed 49% reduced dementia risk
- 2021 meta-analysis of 113 million people found higher groundwater lithium correlates with fewer suicides
- Lithium at 150mg reduced opiate use by 50%, benzodiazepine use by 99%, and illicit drug use by 79%
- Dr. James Greenblatt uses 2-10mg lithium orotate for irritability, especially with family history of addiction or bipolar
- Consumer Labs top-rated brands: Swanson Lithium Orotate 5mg, Solaray Lithium Aspartate 5mg, Life Extension Memory Protect 1mg
- Lithium orotate form has better absorption with fewer side effects than lithium aspartate
Key Moments
Microdose lithium prevents Alzheimer's cognitive decline
Karen reviews a double-blind placebo-controlled trial where 300 micrograms of lithium daily prevented cognitive decline in Alzheimer's patients over 15 months. Those on lithium maintained stable cognitive scores while the placebo group declined from 20 to 14 out of 30 on the Mini Mental Status Exam.
"those who were taking lithium had many mental status Exam scores that remained the same at the end of the trial, the same as the beginning numbers, in other words, no decline, while those who were taking the plus cibo continued to decline"
Lithium reduces dementia risk by 49% in bipolar patients
A 2020 review compared 6500 bipolar patients on lithium to 43,000 untreated individuals and found lithium treatment reduced dementia risk by 49%. Long-term follow-up of a 2011 trial confirmed surviving lithium recipients had significantly higher memory and verbal fluency scores decades later.
"they found that lithium treatment reduced dementia risk in the bipolar patients by forty nine percent"
Groundwater lithium linked to fewer suicides globally
A 2021 meta-analysis of 113 million people across 2700 regions found that areas with higher lithium in groundwater have fewer suicides and fewer admissions to mental health facilities, supporting lithium's potential as a safe addition to suicide prevention approaches.
"The review included one hundred and thirteen million people in almost twenty seven hundred regions across the globe. The study found that the areas that have higher levels of lithium in the groundwater, have fewer suicides and fewer admissions to mental health facilities"
