If you’ve been dealing with symptoms like fatigue, brain fog, stubborn weight, anxiety, or irregular cycles, your thyroid might be trying to get your attention. But here’s the catch: even if you’re taking thyroid medication, eating well, and doing “all the right things,” you might still feel off.
Why? Because there’s another crucial organ involved that often gets overlooked…
Your liver.
Your Thyroid Needs Your Liver
Your thyroid gland (a small butterfly-shaped gland at the base of your neck) produces hormones that regulate everything from your metabolism and temperature to mood and menstrual cycles. But those hormones don’t work in isolation.
The thyroid primarily produces a hormone called T4, which is inactive in the body. For your cells to use it, T4 must be converted into T3, the active form of thyroid hormone.
And guess where up to 60% of that conversion takes place?
In your liver.
So if your liver is sluggish, congested, or overwhelmed (think toxins, stress, processed foods), it may not be converting T4 properly — leading to a cascade of low thyroid symptoms even if your thyroid is technically doing its job.
The Vicious Cycle
Here’s where it gets interesting:
-
Poor liver function leads to less T3 conversion, which leads to low thyroid function
-
Low thyroid function slows down liver detoxification
-
More toxins build up, which further suppresses thyroid function
It becomes a cycle many people don’t even know they’re trapped in.

A Natural Approach: Castor Oil Packs for the Thyroid and Liver
One of the most gentle, effective ways to support both the liver and thyroid at home is with castor oil packs — a therapy used for centuries to encourage detoxification, reduce inflammation, and support hormone balance.

Reduce inflammation

Other Ways to Support Your Thyroid
While castor oil packs are powerful on their own, thyroid health thrives on a holistic approach. Consider also:
-
Eating selenium- and iodine-rich foods (Brazil nuts, seaweed, eggs)
-
Avoiding endocrine disruptors like BPA, synthetic fragrances, and harsh cleaning products
-
Managing stress and supporting adrenal health
-
Prioritising sleep and staying hydrated
Final Thoughts
If you’re navigating thyroid issues, don’t overlook the liver. These two organs work hand-in-hand to keep your hormones and your whole body in balance.
Supporting both with castor oil packs is a simple, nurturing way to reconnect with your body’s natural rhythms and take your wellness into your own hands.
