What Does the Thyroid Do and why is it so Important?

The thyroid, or glandula thyreoidea, is responsible for producing T3 (triiodothyronine) and T4 (thyroxine) hormones. These hormones affect almost every organ and tissue in the body. They regulate metabolic rate and thus the amount of energy the body uses during rest (basal metabolism). Additionally, thyroid hormones play a significant role in:

• Nervous system development: especially in early childhood and during pregnancy.
• Heart rate and blood pressure regulation: helping maintain a balanced cardiovascular system.
• Maintaining body temperature: especially during sudden environmental changes.
• Metabolism of macronutrients: proteins, carbohydrates, and fats.
• Weight control: thyroid disorders often manifest in sudden weight gain or loss.

In short, a healthy thyroid is essential for the smooth functioning of the entire organism. When problems such as hypothyroidism (underactive thyroid) or hyperthyroidism (overactive thyroid) occur, various health issues arise. Hypothyroidism, for example, manifests in fatigue, slow pulse, weight gain, dry skin, and depression, while hyperthyroidism can cause rapid heartbeat, sudden weight loss, nervousness, and increased sweating.

Iodine: the Fundamental Mineral for Thyroid Function

If we want to maintain a healthy thyroid, the first thing we need to pay attention to is iodine. This essential mineral participates in the synthesis of T3 and T4 hormones. Without sufficient iodine, the thyroid simply cannot produce them in optimal quantities, which can result in hypothyroidism or goiter (enlarged thyroid).

How much Iodine Do We Need?

Daily iodine requirements depend on age, gender, and special conditions (e.g., pregnancy, breastfeeding). The World Health Organization (WHO) recommends approximately:

• Adults: 150 µg daily
• Pregnant women: 220-250 µg daily
• Breastfeeding women: 250-290 µg daily
• Children: depending on age, between 90 and 120 µg daily

In many countries, including Croatia, the problem of dietary iodine deficiency has been solved by iodizing table salt. However, if you significantly reduce salt intake for health reasons or consume mostly unprocessed foods, you might not be getting enough iodine in your diet.

Dietary Sources of Iodine

There are several main sources of iodine worth including in your regular diet:

• Iodized salt: The most accessible source of iodine. However, watch your total salt intake due to the risk of high blood pressure and other heart problems.
• Sea fish and seafood: Cod, tuna, mackerel, and shellfish can be excellent sources of iodine.
• Seaweed: For example, nori, wakame, kombu, and kelp, extremely rich in iodine. But be careful with the amount as excessive intake can also be harmful.
• Milk and dairy products: In some countries, livestock receives iodine-rich feed, which increases the iodine content in milk.

Selenium: Important Thyroid Protector

Along with iodine, another key mineral for a healthy thyroid is definitely selenium. This is an element that participates in converting T4 (thyroxine) into the more biologically active T3 (triiodothyronine). Additionally, selenium plays an important role in protecting thyroid cells from oxidative stress and helps regulate immune response.

Why is Selenium’s Antioxidant Role Important?

The thyroid gets “worn out” during the processing of large amounts of iodine and constant hormone production. This metabolic activity leads to the creation of reactive oxygen species (free radicals), which can damage cells if there aren’t enough antioxidants. Selenium is one of the key antioxidant micronutrients in the body, and without adequate selenium levels, the thyroid can be under greater stress and damage.

Recommended Daily Selenium Intake

The recommended daily intake of selenium is approximately 55 µg for adults, while for pregnant and breastfeeding women, recommendations range between 60 and 70 µg. However, keep in mind that selenium intake also depends on the quality of soil where foods are grown (for example, the selenium content in Brazil nuts can vary significantly depending on the growing region).

Natural Sources of Selenium

• Brazil nuts: often cited as the richest source of selenium, though selenium content can vary.
• Sea fish and seafood: cod, tuna, sardines, and other fish are also good sources of selenium.
• Grains: whole grains, especially if grown in selenium-rich soil.
• Eggs and poultry: especially if poultry receives selenium-enriched feed.

While selenium can be supplemented, it’s important not to overdo it, as excessive selenium intake can cause unpleasant side effects (e.g., hair loss, brittle nails, digestive issues). If you’re considering taking selenium supplements, consult with your doctor or nutritionist.

Other Key Nutrients for a Healthy Thyroid

Along with iodine and selenium, optimal thyroid function requires a balance of other vitamins and minerals. Here’s an overview of the most important ones:

1. Zinc

Zinc is a mineral that participates in thyroid hormone production and immune system regulation. Zinc deficiency can worsen hypothyroidism and may lead to increased susceptibility to infections. The most common natural sources of zinc are meat, shellfish, pumpkin seeds, and nuts.

2. Iron

This mineral is crucial for many metabolic processes, including oxygen transport to cells. Low iron levels can affect proper thyroid hormone synthesis. Red meat, legumes, spinach, and lentils are excellent sources of iron. When consuming plant-based iron (e.g., from legumes), combine it with vitamin C-rich foods to improve absorption.

3. Vitamin D

Vitamin D is essential for immunity, but research shows that people with autoimmune thyroid diseases (like Hashimoto’s thyroiditis) often have lower vitamin D levels. Sun exposure is one of the main ways to synthesize this vitamin, but during winter months or in conditions of reduced sunlight, it’s good to consider supplements.

4. Vitamin B12

Vitamin B12 deficiency is often associated with chronic fatigue and anemia. People with thyroid disorders may be more prone to low levels of this vitamin, especially in cases of autoimmune conditions that can impair nutrient digestibility. Meat products and eggs are the main sources of B12, and vegetarians or vegans should consider supplements.

Impact of Stress on the Thyroid

Besides diet, lifestyle is very important for a healthy thyroid. Long-term exposure to stress can lead to hormonal system disorders, including thyroid hormones. When you’re under chronic stress, the body produces more cortisol, which can interfere with the conversion of T4 to T3 and worsen symptoms of hypothyroidism or hyperthyroidism.

Stress reduction techniques like yoga, meditation, deep breathing, regular sleep, and moderate exercise can significantly contribute to better thyroid function. Therefore, it’s recommended to include activities that relax mind and body in your routine, along with healthy eating.

Autoimmune Thyroid Disorders and Dietary Approach

Autoimmune disorders, such as Hashimoto’s thyroiditis (often associated with hypothyroidism) and Graves’ disease (more commonly causing hyperthyroidism), require even more careful planning of diet and supplements. Inflammatory processes can be alleviated by consuming:

• Anti-inflammatory foods: berries, fatty fish (rich in omega-3), olive oil, nuts, and seeds.
• Fermented products: yogurt, kefir, sauerkraut, kombucha – contribute to balanced gut microflora which is important for immune balance.
• Gluten-free diet (if needed): Some experts claim that in autoimmune thyroid diseases, eliminating or reducing gluten can decrease inflammation, although scientific studies are not yet entirely unanimous in fully confirming this thesis.

In these conditions, consulting with a doctor or nutritionist is crucial, as nutrient imbalance and inappropriate diet can further burden an already exhausted thyroid.

Forever Living Products and Thyroid Support

Many people seek supplements to support their thyroid and help maintain balance. While supplementation cannot replace professional diagnosis and therapy, some formulations can provide helpful support. When it comes to Forever Living range, products like Forever Arctic Sea (rich in omega-3 fatty acids) or Forever Daily (vitamin and mineral blend) can fit into an overall plan for a healthy thyroid.

Omega-3 fatty acids from Forever Arctic Sea help reduce inflammatory processes, while Forever Daily offers additional support with vitamins and minerals, including zinc and selenium in optimal ratios.

What is the Role of Aloe Vera in Maintaining a Healthy Thyroid?

Aloe vera is mainly known for its beneficial effects on skin and digestive system, but its anti-inflammatory potential and contribution to better digestive processes can indirectly affect thyroid function. Forever Aloe Vera Gel, for example, is often mentioned as a useful supplement because:

• It helps maintain gut health and absorption of important nutrients.
• It can have a calming effect on inflammatory processes in the body.
• It contains various vitamins, minerals, and amino acids, although not directly iodine or selenium in significant amounts.

Of course, aloe vera itself isn’t a “magic wand” for the thyroid, but it’s a good companion to a balanced diet, especially for those who want to be more careful about the foods they consume.

Common Mistakes in Thyroid Care

Whether you’ve already been diagnosed with a thyroid disorder or just want to maintain a healthy thyroid, watch out for these pitfalls:

1. Self-dosing iodine: Although iodine is crucial, excessive intake can cause new problems and further burden the thyroid.
2. Ignoring symptoms: Long-term fatigue, sudden weight changes, or mood problems shouldn’t be attributed to “ordinary” stress or aging without checking hormonal status.
3. Inadequate diet: Too much processed food, sugar, and lack of fresh foods can worsen thyroid function, especially in autoimmune disorders.
4. Skipping check-ups: People with genetic predisposition or those who have already experienced thyroid disorders should regularly monitor hormone levels (TSH, T3, T4) and consult with a doctor.

Research and Scientific Sources

Thyroid health is the subject of numerous scientific studies. For example, one study (PubMed) emphasizes the importance of selenium in preventing and treating autoimmune thyroid diseases, while another study links iodine deficiency with increased risk of hypothyroidism. These papers confirm that appropriate intake of essential minerals, along with a healthy lifestyle, is extremely important for this gland’s functionality.

Frequently Asked Questions (FAQ) about Healthy Thyroid

1. Can Supplements Replace Thyroid Medications?

No. If your doctor has prescribed hormone therapy or other medications, it’s strictly important to take them as directed. Supplements, such as iodine or selenium, can be valuable additions but should not replace prescribed medical therapy.

2. Can “Too much” Iodine or Selenium Harm the Thyroid?

Yes, definitely. Although iodine and selenium are necessary, excessive intake can cause toxic reactions and disrupt thyroid function. Therefore, it’s crucial to stick to recommended daily doses or follow advice from your doctor or nutritionist.

3. Is there a Connection between Stress and Thyroid Disorders?
