l-Thyroxine was the first synthetic molecule used to treat hypothyroidism (23) and was shown to be efficacious as monotherapy for myxedema (24). Around that time, serum protein-bound iodine (PBI) emerged as a diagnostic test and therapeutic marker; serum PBI quantitation was the only valid way to biochemically assess thyroid hormone status (25). This tool was limited in terms of treatment monitoring because the effect on serum PBI varied by agent (26). For example, l-triiodothyronine corrected BMR without much increase in serum PBI, l-thyroxine increased serum PBI sometimes to above normal, and combination l-thyroxine and l-triiodothyronine and desiccated thyroid had the advantage of normalizing serum PBI (27). In addition to BMR and serum PBI, other surrogates for treatment response included cholesterol levels, symptoms, and deep tendon reflexes, but their lack of sensitivity was always recognized (28).

Blood sugar imbalances are major contributers to the development of hypothyroidism.   When our blood sugar gets too high (hyperglycemia) the sugar molecules bind to proteins in the body and create Advanced Glycolytic Enzymes (AGEs) (56). The AGEs destroy cell membrane function and damage insulin receptor activity creating a vicious cycle of elevated blood sugar and inflammatory stress.

In the past, doctors weren't able to detect hypothyroidism until symptoms were fairly advanced. But by using the sensitive TSH test, doctors are able to diagnose thyroid disorders much earlier — often before you experience symptoms. Because the TSH test is the best screening test, your doctor will likely check TSH first and follow with a thyroid hormone test if needed. TSH tests also play an important role in managing hypothyroidism. They help your doctor determine the right dosage of medication, both initially and over time.
Think milk, butter, cheese, and meat. If you buy the cheap, conventionally raised versions at the supermarket, those types of deliciousness can also disrupt all your thyroid’s hard work. You omnivores (like us) can avoid this dilemma by choosing organic, or at least antibiotic-free and hormone-free meats and dairy. It’ll save you in the end, with fewer medical costs down the line.
Alcohol consumption can wreak havoc on both thyroid hormone levels in the body and the ability of the thyroid to produce hormone. Alcohol appears to have a toxic effect on the thyroid gland and suppresses the ability of the body to use thyroid hormone. Ideally, people with hypothyroidism should cut out alcohol completely or drink in careful moderation.
In areas of the world where there is an iodine deficiency in the diet, severe hypothyroidism occurs in about 5% to 15% of the population. Examples of these areas include Zaire, Ecuador, India, and Chile. Severe iodine deficiency occurs in remote mountain areas such as the Andes and the Himalayas. Since the addition of iodine to table salt and to bread, iodine deficiency is rare in the United States.
l-Thyroxine monotherapy for athyreotic rats results in a high T4:T3 ratio at doses sufficient to normalize serum TSH levels (8). Yet, the brain, liver, and skeletal muscle tissues of these l-thyroxine–treated animals continue to exhibit markers of hypothyroidism (9), probably because of the inability of l-thyroxine monotherapy to restore tissue levels of T3 (8). This is probably a direct consequence of lower serum T3 levels and the relatively high T4 concentration in these tissues, which inactivates the type 2 iodothyronine deiodinase (D2). In the hypothalamus, loss of D2 is minimal in the presence of T4, which increases sensitivity to T4 levels and explains TSH normalization, despite relatively lower levels of serum T3. Only combination therapy with l-thyroxine plus l-triiodothyronine normalized all thyroid hormone–dependent measures (9), including serum and tissue T3 levels (8). Whether tissue-specific markers of hypothyroidism are restored with l-thyroxine monotherapy in humans remains to be determined, as does the ability of l-thyroxine plus l-triiodothyronine combination therapy to normalize the serum T4:T3 ratio without adverse events. The development of a novel drug delivery system for l-triiodothyronine would facilitate these studies (5).
60 patients with borderline hypothyroidism were given either 2 mg of soy isoflavones (the amount found in the typical omnivore’s diet) or 16 mg of soy isoflavones (the amount found in the typical vegetarian’s diet).  The “vegetarian” dose of soy isoflavones was 3 times more likely to cause patients to convert from borderline (“subclinical”) hypothyroidism to full-blown (“overt clinical”) hypothyroidism.

Many allergies and food intolerances today are from wheat and dairy products. This is because of the hybridized proteins of gluten and a1 casein. These proteins can lead to “leaky gut”, which in turn will cause inflammation of the thyroid and effect its function. If you can’t follow a grain-free diet, at least cut out gluten. Additionally, only consume dairy products that come from A2 cows, goat milk, or sheep milk. (2)


Why does this happen? The immune system mistakenly thinks that the thyroid cells are not a part of the body, so it tries to remove them before they can cause damage and illness. The problem is that this causes widespread inflammation, which can result in many different problems. According to Dr. Datis Kharrazian, 90 percent of people with hypothyroidism have Hashimoto’s that inflames the thyroid gland over time, but this isn’t the only cause of hypothyroidism.

Vitamin B12 and thiamine are important for neurologic function and hormonal balance. Research shows that supplementing with thiamine can help combat symptoms of autoimmune disease, including chronic fatigue. In one clinical study, when patients with Hashimoto’s were given 600 milligrams per day of thiamine, the majority experienced complete regression of fatigue within a few hours or days. (18)
Wild-caught fish – These provide omega-3 fatty acids EPA/DHA that are essential for hormone balance and thyroid function. Balancing the level of omega-3 to omega-6 fatty acids in your hypothyroidism diet can reduce inflammation and support healthy neurological function. Wild fish like salmon, mackerel and sardines are some of the best sources of omega-3s to increase neurotransmitter activity and support a healthy mood and immune system.
Ashwagandha is an adaptogen herb that helps the body respond to stress, keeping hormone levels better in balance. Adaptogens helps lower cortisol and balance T4 levels. In fact, in clinical trials, supplementing with ashwagandha for eight weeks essentially worked as thyroxine treatment, helping hypothyroidism patients significantly increase thyroxine hormone levels and thus reduce the severity of the disorder. (13) Also, try other adaptogen herbs like rhodiola, licorice root, ginseng and holy basil, which have similar benefits.
Hypothyroidism is a disorder caused due to inadequate production of thyroid hormone, in comparison to the normal body requirements. In this condition, the thyroid gland is said to be 'underactive'. Insufficient thyroid hormone results into slowing down of the overall body metabolism. Hypothyroidism affects both men and women, but women are eight times more susceptible. People of all ages can be affected by this disorder and over 5 million Americans have this disorder. Hypothyroid people are susceptible to cancers, heart disorders, and infections. Severe hypothyroidism in adults is called 'Myxedema' and in children it is called 'Cretinism'.
Similar to processed foods, fast food chains also aren't required to use iodized salt in their foods. And even when they do, it might not boost the iodine content all that much, according to one 2010 commentary in the journal Endocrine Practice, which tested products from two fast food restaurants in the Boston area. The study authors concluded that drive-thru fare might be pretty low in iodine.

Hypothyroidism is a secondary cause of dyslipidemia, typically manifesting in elevation of low-density lipoprotein and total cholesterol levels. It is clear that treatment resulting in the normalization of the serum TSH is associated with reduction in total cholesterol levels (54), but whether total cholesterol is fully normalized by l-thyroxine monotherapy is less well-defined. An analysis of 18 studies on the effect of thyroid hormone replacement on total cholesterol levels in overt hypothyroidism showed a reduction in the total cholesterol level in all 18 studies; however, in 14 of the 18 studies, the mean post treatment total cholesterol level remained above the normal range (>200 mg/dL [>5.18 mmol/L]) (55). These findings suggest that lipid measures are not fully restored despite normalization of the serum TSH (56). Whether the degree of dyslipidemia remaining in l-thyroxine-treated patients with a normal TSH is clinically significant is unknown, given that the benefit of thyroid hormone replacement in subclinical hypothyroidism is itself controversial (57, 58).
Physicians hesitated to use l-thyroxine monotherapy over concern that it could result in a relative T3 deficiency, despite growing discontent with potency of natural thyroid products (39) and reduced cost of l-thyroxine, such that the 2 treatments were approximately equivalent (36, 41). The seminal discovery of peripheral T4-to-T3 conversion in athyreotic individuals largely obviated this concern (42). This laid the foundation for the corollary that treatment with l-thyroxine could replace thyroid hormone in such a way that the prohormone pool would be restored and the deiodinases would regulate the pool of active T3. Within a decade there was a major transition toward l-thyroxine monotherapy as first-line therapy (Appendix Table and Figure) (38).
The most common treatment I use is Armour thyroid, (9) a prescription drug made from desiccated (dried) porcine thyroid. It contains the full spectrum of thyroid hormones, including T4, T3, and T2 (10). That last one – T2 – is a little-known product of thyroid metabolism that actually may be very important. The right dose ranges from 15 to 180 milligrams, depending on the person.
Could kale, that superstar among superfoods, actually not be quite so awesome? Kale is a mild goitrogen -- in rare cases it prevents the thyroid from getting enough iodine. But kale shouldn't be a problem for you unless you get very little iodine in your diet and you’re eating large amounts of kale. This is also the case for cabbage, broccoli, cauliflower, and Brussels sprouts.  

It is medically proven that small frequent meals are healthier for persons with hypothyroidism compared to eating large-bulky meals per day. A study showed that eating 5-6 small meals a day will help a person lose weight and ward off the symptoms of the disease. It does not only help your intestines to digest food, it also keeps your energy level up.


Your article is really helpful. I was diagnosed with hypothyroid almost 7 years back using imaging of gland and started off with 50 mcg of thyroxine which gradually increased to 100 mcg. My mother and both the brothers also have the problem but they live a normal life. However, I feel chronic throat infection (almost every month), viral fever (mild fever running for long duration), my throat reacts to the cold weather, dust etc. I feel extreme fatigue most time. Since last two years, my condition has worsen. My T3 level is usually at the lower end (even after medication). I used to take protein suppliments which caused me lot of stomach troubles and eggs too. Now I have stopped all the heavy proteins. How can I live a normal life? I am 43 years old male (a scientist) and want to have an active life and career. Please help me.

11.  Methylation:  Methylation is a key process that protects DNA, turns on and off genetic traits and helps to detoxify environmental chemicals.  Many individuals have certain genetic polymorphisms that limit their ability to appropriately methylate. Methylation plays a very important role in T cell function and poor methylation status is associated with the development of auto-immunity (31).
Many people want to know how to cure hypothyroidism permanently.  It helps to know that those who have hypothyroidism often have it because they have hashimoto’s thyroiditis, which is an autoimmune disease. As such, you must get to the source of the imbalance, not simply cover up the symptoms with medication. (14) In fact, in some cases, treatment of hyperthyroidism can result in permanent hypothyroidism. (15)
You need to reduce the toxins you ingest from additives, preservatives, artificial sweeteners (!), excessive sodium, and trans-fats and try to eliminate toxins hiding around your house. Water toxicity is a HUGE problem in thyroid conditions. Most public water systems in the US have fluoride added, which is now linked to slowing down the thyroid; fluoride is believed to be leaching on to the thyroid cells inhibiting the uptake of iodine, hence the altered production of the thyroid hormone (T4).
