A little lithium and B-12 makes the world a happier place – for some.

A Little Lithium + B12 may make the world a happier place - depending on your #genetic snps. When first digging into my 23andMe data, I really found Dr. Amy Yasko’s websites to be very informative and interesting to read.  Most of her work is with Autistic children, but her explanations of how the methylation cycle and other biochemical cycles work are easy to read and can be applicable to everyone.

One thing that I discovered through reading her works is that some of us need and use more of the mineral lithium than others.  She recommends checking lithium levels for all autistic children and suggests supplementing with low levels of lithium for MTR/MTRR mutations.  Dr. Yasko states that ” Lithium not only plays a role in mood, glutamate control and limiting aggression but also has been shown to be involved in B12 transport.”[ref]  She recommends making sure your lithium level is in balance before adding in B12.  In addition to Dr. Yasko’s clinical work associating B12 and lithium, there are several studies showing this as well. [ref] [ref]

Before going any further into this, I want to clarify that I’m referring to supplementing with an over-the-counter mineral supplement of lithium orotate or lithium aspartate.  This is different than the large, prescription doses of lithium carbonate used for bipolar disorder.  Lithium is actually a naturally occurring mineral that is found in foods at concentrations dependent upon the mineral content of the soil.

On a personal note, one family member (who is homozygous for several of the snps below) found that supplementing with lithium orotate and B12 to be extremely helpful and is no longer irritated by, well, everyone and everything.  The rest of the family, without the homozygous SNPs, doesn’t really notice any difference when taking lithium, showing once again that everyone is different.  It is truly amazing, though, the difference it makes when you hit on the right food or supplement for your body and your genes.

Lithium orotate and lithium aspartate are both available in health food stores and online in 5 mg doses.  Amazon carries several brands including Seeking Health’s Lithium Orotate (5mg) and Weyland’s Lithium Orotate (5mg or 10mg)*.

Genes involved:
Here is a list of the MTR and MTRR SNPs involved and the allele to look for:

Dr. Yasko also has an excellent video of a seminar where she lays out her research on the effects of lithium. It is worthwhile to spend some time watching it: http://www.dramyyasko.com/resources/webisodes/lithium-connection-webisode   She makes the case that lithium, through the inhibition of thioredoxin, can increase COMT, which is an enzyme that regulates and degrades dopamine, epinephrine, and norepinephrine.    She now also checks the COMT status in regards to lithium supplementation.

Lithium and Polyunsaturated Fatty Acids (PUFA):
Several studies have found that lithium reduces arachidonic acid (inflammatory polyunsaturated fatty acid) production in the brain.  It is theorized that this reduction of neuroinflammation is the reason that prescription strength lithium chloride works for bipolar disorder.  For more information about genetics and variants that affect fatty acid composition, check out the article on Omega-3 vs. Omega-6 fats and your genes.

These two studies are worth reading if you are interested in the link between lithium and neuroinflammation:

Natural Sources of Lithium:
Lithium occurs naturally in spring water in certain areas and can range from less than 1 mcg/l to well over 100 mcg/l.  It is also found in the soil and can be taken up by plants depending on the concentration in the soil. Here is a map of a few places in the US showing their lithium levels in well water.

A study in 1989 looked at the lithium levels in the water in 27 counties in Texas.  The study showed that counties that had water with higher lithium levels had significantly lower violent crime rates and suicide rates.  There have been several more studies completed more recently in other countries that show the same decrease in suicide and homicide with higher levels of naturally occurring lithium.

Normally, a person has about 2 – 3 mg of lithium in their body.

 Lithium in the News:
There have been a couple of really good articles recently explaining the benefits of a little lithium.

Uses for high dosage lithium:
For well over a century, lithium has been used in high pharmacological doses (typically 300+ mg per day) to treat bipolar disorder and other mood disorders.  It is also being investigated and used to slow the progress of ALS, dementia, and Alzheimer’s disease.

Studies on lithium (pharmacological doses for mood disorders) and genetic polymorphisms:

Studies on lithium levels found naturally in drinking water:

  • Lithium in the Public Water Supply and Suicide Mortality in Greece 2013 – “The purpose of the present study was to evaluate the association between lithium levels in the public water supply and prefecture-based suicide rates in Greece. Analyses were conducted with respect to lithium levels in 149 samples from 34 prefectures of Greece. The average lithium level was 11.10 [mu]g/l (range 0.1 to 121 [mu]g/l). The results indicate that there is a tendency for lower suicide rates in the prefectures with high levels of lithium in drinking water.”
  • A Negative Association Between Lithium in Drinking Water and the Incidences of Homicides, in Greece, 2015 – “total of 149 samples of drinking water were collected from 34 out of 52 prefectures, and data for homicides were taken from National Statistic Service of Greece (Hellenic Statistical Authority – EL.STAT). The average lithium level was 11.10 [mu]g/l (SD=21.16). The results indicate that there is a tendency for a lower mean number of homicides in the prefectures with high levels of lithium in drinking water (R ^sup 2^=0.054, [beta]=-0.38, p=.004).”

Safety of taking lithium:
Prescription levels of lithium do come with long-term side effects including higher risks of hypothyroidism and kidney problems.

  • Lithium toxicity from an internet dietary supplement, 2007 — case study of an 18-year-old who took 18 tablets of Find Serenity Now, each of which contained 120mg of lithium orotate.  She went to the emergency department with nausea and was discharged after a few hours to a psychiatric hospital.
  • Lithium toxicity profile: a systematic review and meta-analysis, 2012 — A meta-study on side effects from prescription dosages of lithium carbonate used for mood disorders showed that lithium increased the risk for hypothyroidism and weight gain.  It also showed an increased risk of renal failure, with overall risk being 0.5%.
