Cookie's Fur Analysis: Lithium

The first element on Cookie's fur analysis results I decided to research closely is lithium (Li). These elements weren't included on Jasmine's analysis, and I don't know anything about it. More importantly, the notes from the lab state the following:

"Lithium is found occurring naturally in some water supplies. Lithium accumulates primarily in the pituitary and thyroid glands. If excessive, lithium will interfere with iodine uptake by the thyroid gland, possibly blocking thyroxine release or thyroid-stimulating hormone (TSH). Therefore, long-term lithium excess may possibly contribute to decreased thyroid activity, fatigue, and weight gain."


Since there clearly have been issues with Cookie's thyroid function, this element stood out to me the most.


Now, none of the other possible conditions associated with excess lithium have been present. Those include:

  • increased urination
  • increased thirst
  • blood sugar disturbances
  • alkaline urine
  • heir loss
  • osteoporosis
  • hypercalciuria
  • leukocytosis


The first thing I did was to consult with Dr. Dodds.


I emailed her the analysis results and asked specifically about the potential connection between lithium levels found in Cookie's fur and poor thyroid function. Mainly since Cookie was negative for autoimmune thyroiditis.

She replied that the analysis would not explain Cookie's hypothyroidism.

It is also true that ratios between nutritional elements indicate normal thyroid function which we now know was not normal. So what does one make of all this?

What is lithium?


You might be familiar with the use of lithium in rechargeable batteries. But what the heck would it be doing in Cookie's fur? Was it from water? Cookie gets bottled water to drink, but she also drinks water from puddles and ditches. I plan on having both water sources analyzed (makes the most sense to do both at the same time) which means, though, that I have to wait until the outdoor water thaws out.

Trace amounts of lithium can also be found in plants. It can be found in kelp, fish as well as in dairy, eggs, and meat in minute concentrations. Legumes and grains contain it too, but Cookie doesn't eat those.

Some sources cite there is no known function of lithium in the body, others assert that lithium plays a role in B12 transport to cells, as well as neurological function.

So far I'm none the wiser.

Now, during the winter, Cookie only has access to snow and the bottled water we give her. It will be interesting to see how much the levels will reflect that change. As well as once the puddles and the ditch thaw out, I will have the water tested and see what we can learn.
