Overview
Hypothyroidism is a condition where the thyroid gland does not produce enough thyroid hormones, which are crucial for regulating metabolism and energy.
Hypothyroidism, also known as underactive thyroid, occurs when the thyroid gland, a small butterfly-shaped gland located at the base of the neck, fails to produce sufficient amounts of thyroid hormones. These hormones, primarily thyroxine (T4) and triiodothyronine (T3), play a vital role in regulating the body's metabolism, affecting nearly every organ system. When hormone production is insufficient, many bodily functions slow down.
The most common cause of hypothyroidism in developed countries is Hashimoto's thyroiditis, an autoimmune disease where the immune system mistakenly attacks the thyroid gland. Other causes can include iodine deficiency, certain medications, radiation therapy to the neck, surgical removal of part or all of the thyroid, and congenital thyroid defects. Symptoms often develop slowly over many years and can be subtle, making diagnosis challenging in its early stages. If left untreated, hypothyroidism can lead to more severe health problems.
Why it may help Hypothyroidism: Low vitamin D levels are frequently observed in individuals with hypothyroidism. While the exact interplay is still being explored, vitamin D is known to modulate immune responses, which may be relevant in autoimmune forms of hypothyroidism like Hashimoto's thyroiditis. It also supports general metabolic processes that could be compromised during thyroid dysfunction.
Typical dose
2000-5000 IU/day
Mechanism
Plays a role in immune modulation; deficiency is common in autoimmune thyroid conditions.
Notes
Monitor blood levels to ensure optimal range.
Evidence
moderate
Individuals with thyroid disorders should discuss vitamin D supplementation with their healthcare provider, as excessive intake may interfere with certain medications or exacerbate pre-existing conditions. Hypercalcemia remains a general safety concern at very high, unmonitored intakes.
Why it may help Hypothyroidism: Zinc is essential for the synthesis of thyroid-releasing hormone (TRH) and thyroid-stimulating hormone (TSH), and its deficiency can impair thyroid hormone production and conversion.
Typical dose
8-15 mg/day
Mechanism
Involved in thyroid hormone synthesis and conversion of T4 to T3.
Notes
Can interact with copper absorption; consider balanced intake.
Why it may help Hypothyroidism: Vitamin D modulates the immune system and thyroid hormone synthesis, and its deficiency is associated with increased risk and severity of autoimmune thyroid conditions like Hashimoto's.
Typical dose
2000-5000 IU/day
Mechanism
Plays a role in immune modulation; deficiency is common in autoimmune thyroid conditions.
Ginseng is a traditional adaptogenic herb, primarily from the Panax genus, commonly used for energy, cognitive support, and stress adaptation, though scientific evidence for many uses is still emerging.
Why it may help Hypothyroidism: Black seed oil, also known as Nigella sativa, contains compounds like thymoquinone that appear to exert anti-inflammatory and antioxidant effects. In the context of Hashimoto's thyroiditis, which often underlies hypothyroidism, thymoquinone has been studied for its potential to modulate the NF-κB pathway and reduce oxidative stress, both of which are implicated in thyroid autoimmunity. It has also been observed in preliminary research to potentially lower thyroid peroxidase (TPO) antibodies.
Individuals with hypothyroidism, especially those taking thyroid hormones, should be aware that black seed oil may interact with medications. It appears to have potential blood pressure and blood sugar-lowering effects, which should be considered with co-existing conditions or medications. Pregnant individuals are advised to avoid its use.
Why it may help Hypothyroidism: Selenium is a trace mineral that serves as a cofactor for deiodinase enzymes, which play a crucial role in converting the thyroid hormone T4 (thyroxine) into its more active form, T3 (triiodothyronine). Additionally, selenium is integral to glutathione peroxidase, an antioxidant enzyme that helps protect the thyroid gland from oxidative stress, which may be relevant in supporting overall thyroid health. Therefore, adequate selenium intake appears important for optimal thyroid function and hormone metabolism.
Excessive selenium intake can lead to toxicity, known as selenosis, which could potentially exacerbate certain symptoms. Individuals with hypothyroidism considering selenium supplementation should do so cautiously and be aware of their total daily intake from all sources to avoid exceeding the upper tolerable limit, often around 400 mcg/day. Limiting intake to 1-3 Brazil nuts per day is generally advised.
Why it may help Hypothyroidism: Iodine is an essential trace element crucial for the synthesis of thyroid hormones triiodothyronine (T3) and thyroxine (T4). In individuals with iodine deficiency, supplementing with iodine, such as from kelp, may support adequate thyroid hormone production. This can be particularly relevant for hypothyroidism caused by insufficient iodine intake.
Typical dose
150-250 mcg/day
Mechanism
Essential component of thyroid hormones (T3 and T4).
Notes
Only supplement if deficiency is confirmed, as excess iodine can worsen autoimmune thyroid conditions. Kelp is a natural source.
Evidence
strong
Individuals with pre-existing thyroid conditions, especially Hashimoto's thyroiditis, should exercise extreme caution with iodine supplementation. Excess iodine intake can potentially worsen autoimmune thyroid conditions or induce hyperthyroidism; therefore, thyroid function and iodine levels should be tested and monitored by a healthcare professional.
Why it may help Hypothyroidism: Ashwagandha contains compounds called withanolides, which have been studied for their potential to modulate the hypothalamic-pituitary-adrenal (HPA) axis. This modulation may influence thyroid-stimulating hormone (TSH), triiodothyronine (T3), and thyroxine (T4) levels, particularly in individuals with subclinical hypothyroidism. By potentially supporting thyroid hormone balance, ashwagandha may offer benefits for managing symptoms associated with an underactive thyroid.
Typical dose
300-600 mg extract/day
Mechanism
Adaptogen that may help modulate stress response and support thyroid function, potentially increasing T4 levels.
Notes
Avoid if hyperthyroid. Consult a healthcare provider.
Evidence
limited
Individuals with diagnosed hypothyroidism or those taking thyroid medications should consult a healthcare provider before using ashwagandha, as it may interact with thyroid hormone levels and medications. Ashwagandha is generally not recommended for individuals with hyperthyroidism, as it may increase thyroid hormone activity.
Why it may help Hypothyroidism: A 9-month open-label trial in 30 women with Hashimoto-related subclinical hypothyroidism found 50 ml/day of aloin-free Aloe vera juice normalized TSH, raised free T4, and lowered thyroperoxidase antibodies, suggesting reduced autoimmune inflammation and improved thyrocyte function (Metro et al., 2018, PMC5842288).
Individuals with hypothyroidism, especially those taking thyroid hormone replacement medications, should use aloe vera juice with caution. There is a theoretical concern for potential interactions with medications, as aloe vera may affect drug absorption or metabolism. Pregnant individuals should avoid aloe vera juice.
Why it may help Hypothyroidism: Iron is a crucial cofactor for thyroid peroxidase, an enzyme essential for the synthesis of thyroid hormones, and iron deficiency can impair thyroid function.
Typical dose
Varies based on deficiency
Mechanism
Iron deficiency can impair thyroid hormone synthesis and metabolism.
Notes
Only supplement if iron deficiency anemia is diagnosed. Iron Bisglycinate is a well-tolerated form.
Why it may help Hypothyroidism: Selenium is a key component of selenoproteins, including deiodinases, which are enzymes responsible for converting inactive T4 into active T3, thus optimizing thyroid hormone metabolism.
Typical dose
50-200 mcg/day
Mechanism
Supports thyroid hormone production and conversion, acts as an antioxidant, may reduce thyroid antibodies in Hashimoto's.
Notes
Brazil Nuts are a good dietary source. Excessive intake can be toxic.
Why it may help Hypothyroidism: Iodine is an essential component of thyroid hormones (T3 and T4), and adequate intake is necessary for the thyroid gland to synthesize these hormones and prevent hypothyroidism.
Typical dose
150-250 mcg/day
Mechanism
Essential component of thyroid hormones (T3 and T4).
Notes
Only supplement if deficiency is confirmed, as excess iodine can worsen autoimmune thyroid conditions. Kelp is a natural source.
Why it may help Hypothyroidism: L-Tyrosine is a precursor to thyroid hormones, and its availability is necessary for the thyroid gland to synthesize T3 and T4, supporting overall thyroid function.
Typical dose
500-1000 mg/day
Mechanism
Amino acid precursor to thyroid hormones.
Notes
May be beneficial in some cases, but not a substitute for thyroid hormone replacement.
Why it may help Hypothyroidism: Bladderwrack contains iodine, a crucial component of thyroid hormones, and can support thyroid function in cases of iodine deficiency, which is a cause of hypothyroidism.
Why it may help Hypothyroidism: Iron bisglycinate provides bioavailable iron, which is a crucial cofactor for thyroid peroxidase, an enzyme essential for thyroid hormone synthesis, thereby supporting thyroid function.
Typical dose
Varies based on deficiency
Mechanism
Iron deficiency can impair thyroid hormone synthesis and metabolism.
Notes
Only supplement if iron deficiency anemia is diagnosed. Iron Bisglycinate is a well-tolerated form.

International evidence & guidelines
How global health authorities view Hypothyroidism.
The Mayo Clinic emphasizes that while certain nutrients like iodine and selenium are important for thyroid function, supplementation should be approached cautiously and ideally under medical supervision, especially for iodine, as excessive intake can be harmful. The NIH (National Center for Complementary and Integrative Health) notes that some herbal remedies are used traditionally for thyroid support, but robust scientific evidence for their efficacy and safety in treating hypothyroidism is often limited. They generally advise against using dietary supplements as a substitute for conventional thyroid hormone replacement therapy. The WHO and NHS primarily focus on conventional medical management for hypothyroidism.

Background: Subclinical hypothyroidism, defined by elevated thyrotropin (TSH) and normal free thyroxine levels, is associated with adverse pregnancy outcomes, including preterm birth, pre-eclampsia, and small for gestational age. Despite the uncertainty regarding the effectiveness of levothyroxine (LT4) treatment on pregnancy outcomes in subclinical hypothyroidism, LT4 is widely administered with a pre-treatment threshold TSH level of 2.5 mU/L. The aim of this study is to investigate the efficacy of periconceptional LT4 treatment for subclinical hypothyroidism, including TSH levels >2.5 mU/L, and identify the characteristics of subclinical hypothyroidism that can benefit from LT4 treatment. Methods: We conducted a systematic review and meta-analysis of randomized controlled trials from inception to February 2023. We analyzed the pooled effects of LT4 on subclinical hypothyroidism before and during pregnancy. The main outcomes before pregnancy were live birth, pregnancy

Iron is one of the essential microelements necessary for maintaining the body's homeostasis. It serves various roles, including being a crucial component in the proper structure of many enzymes and supporting the transport of oxygen and electrons. Its deficiency can lead to anaemia, which is a common clinical condition often associated with thyroid diseases. Iron deficiency is one of the most common nutritional deficiencies, and its prevalence is strongly associated with socioeconomic status. It is the primary cause of anaemia in 42% of children and 50% of women. Importantly, iron deficiency is placed among the top 5 causes of disability in women. Thyroid peroxidase (TPO) is an enzyme essential for the production of thyroid hormones, and iron is a key factor in its proper functioning. Therefore, in the case of iron deficiency, the activity of this enzyme is also reduced. Iron is also a factor that is important in epigenetic modification processes, and its deficiency may contribute to g

In recent years, a growing number of studies have examined the relationship between thyroid pathophysiology and intestinal microbiota composition. The reciprocal influence between these two entities has been proven so extensive that some authors coined the term "gut-thyroid axis". However, since some papers reported conflicting results, several aspects of this correlation need to be clarified. This systematic review was conceived to achieve more robust information about: 1)the characteristics of gut microbiota composition in patients with the more common morphological, functional and autoimmune disorders of the thyroid; 2)the influence of gut microbial composition on micronutrients that are essential for the maintenance of thyroid homeostasis; 3)the effect of probiotics, prebiotics and synbiotics, some of the most popular over-the-counter products, on thyroid balance; 4)the opportunity to use specific dietary advice.

β thalassemia (βT) and α thalassemia (αT) are chronic hemolytic anemias caused by hereditary defects in the β or α chains of hemoglobin, respectively. According to the clinical picture, both forms of thalassemia are subdivided into minor, intermedia, or major. Previous guidelines focused on growth and endocrine dysfunctions in βT major, where the complications reported are consequences of iron toxicity. However emerging evidence shows that patients with other forms of thalassemia are also at risk of some endocrinopathies. This guideline provides consensus on the screening and management of endocrine complications of children and adolescents with different forms of thalassemia.

Sodium levothyroxine (LT4) as a monotherapy represents the mainstay of treatment of hypothyroidism, and its use has increased over time. Nevertheless, it faces several potential barriers in its 'real life' utilization, and hence its clinical effectiveness may be marred. This is suggested by the frequent situation of patients failing to reach the therapeutic goals of symptom relief and serum TSH control. Thus, an expert task force was approved by the Guidelines Board of the European Thyroid Association to examine the available data and to formulate recommendations based on the available evidence and the experts' deduction. The task force provides a body of suggestions to optimize the levothyroxine treatment in monotherapy, considering the key point in the individualization of treatment. Furthermore, the nutritional, pharmacological and pathological factors, potentially leading to the increased need for levothyroxine, are discussed, with a specific focus on the use of liquid and softgel

Levothyroxine (LT4) is recommended for intake in a fasting state to optimize absorption. However, fasting intake is often burdensome and may reduce adherence. In a previous questionnaire study, we observed a strong patient preference for taking LT4 with breakfast. Therefore, we conducted a randomized controlled trial to evaluate whether nonfasting LT4 intake-accompanied by a 15% dose increase-could maintain TSH stability compared to fasting LT4 intake.
Adults with well-controlled hypothyroidism were randomized to fasting or dose-adjusted, breakfast LT4 intake. TSH, free T4, and total T3 were measured every 6 weeks, followed by LT4 dose adjustment if needed. The primary outcome was TSH stability, defined as 2 consecutive values within the reference range and a maximum ±1 mIU/L change from baseline. Patients were followed until TSH stability was reached, with a maximum of 24 weeks. After the initial study period, patients in the fasting group were invited to cross over to no

Brassica vegetables are widely consumed all over the world, especially in North America, Asia, and Europe. They are a rich source of sulfur compounds, such as glucosinolates (GLSs) and isothiocyanates (ITCs), which provide health benefits but are also suspected of having a goitrogenic effect. Adhering to PRISMA guidelines, we conducted a systematic review to assess the impact of dietary interventions on thyroid function, in terms of the potential risk for people with thyroid dysfunctions. We analyzed the results of 123 articles of in vitro, animal, and human studies, describing the impact of brassica plants and extracts on thyroid mass and histology, blood levels of TSH, T3, T4, iodine uptake, and the effect on thyroid cancer cells. We also presented the mechanisms of the goitrogenic potential of GLSs and ITCs, the limitations of the studies included, as well as further research directions.

Plant-based diets are gaining popularity due to their well-documented cardiometabolic benefits and environmental sustainability. However, these diets are often lower in specific micronutrients such as iodine, raising concerns about their potential impact on thyroid health. Therefore, we examined the associations between plant-based diets and the risk of hypothyroidism.
We analysed data from the UK (United Kingdom) Biobank cohort. Multivariable Cox proportional hazards regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (95% CIs) for incident hypothyroidism across vegans, vegetarians, pescatarians, poultry-eaters, low meat-eaters, and high meat-eaters aged 40-69 years. Ancillary to this, we carried out logistic regression analyses to evaluate associations between the diet groups and prevalent hypothyroidism according to International Classification of Diseases (ICD) codes at baseline.

Thyroid hormones are substances naturally made by the body and are important to many of your body's basic functions such as breathing and brain function. We are investigating whether or not these hormones are at lower levels in critically ill children which could lead to further health problems. We hope to get a better understanding of hormone levels and their effects on critically ill children to better help other children in the future.
First, to date, no data are available on the thyroid volume of full-term newborns in Italy, making it essential to conduct studies to establish reference values for normality. This allows these values to be correlated with maternal and fetal variability, providing a scientific basis for better understanding thyroid development in the first days of life. Thyroid ultrasound is useful for supplementing newborn screening for congenital hypothyroidism, helping to identify early abnormalities. Furthermore, thyroid volume is a sensitive indicator of iodine intake, essential for assessing the population's iodine nutritional status. It is equally valuable for studying and monitoring the effects of maternal and environmental factors, for which thyroid volume itself serves as a marker. Having normal values allows for a more precise comparison and contextualization of data from children with pathologies, who undergo ultrasound for pathological screening. In summary, these regulatory references improve the diagnosis, prevention, and management of neonatal thyroid dysfunction, contributing to a more informed public health.
