The thyroid is a small, butterfly-shaped gland at the front of the neck that produces hormones controlling your metabolism, energy, heart rate, body temperature and mood. When it does not function well, you may feel tired, gain weight, lose focus or experience mood swings — often long before any lab value changes.
What is the thyroid gland and why is it important?
The thyroid gland is located on the front side of the neck, just below the Adam's apple. It produces two main hormones — thyroxine (T4) and triiodothyronine (T3) — which are responsible for how efficiently every cell in your body converts food into energy. Balanced thyroid function supports a healthy weight, stable energy, normal heart rate, regular digestion and good mood.
Thyroid disorders are much more common than most people think, especially in women. They range from an underactive thyroid (hypothyroidism) to an overactive one (hyperthyroidism) and include autoimmune conditions such as Hashimoto's disease.
Most common signs of a thyroid imbalance
- Constant fatigue and low energy, even after a full night of sleep.
- Unexplained weight gain or difficulty losing weight.
- Feeling cold, dry skin, brittle hair and nails.
- Brain fog, poor concentration and memory problems.
- Low mood, anxiety or irritability.
- Slower heart rate, constipation or irregular digestion.
If you notice several of these signs, see a doctor and ask for thyroid blood tests (TSH, FT4 and FT3) — professional diagnosis always comes first.
Nutrients that support the thyroid
The thyroid needs specific building blocks to produce its hormones. The most important are:
- Iodine — the core component of thyroid hormones, found in iodised salt, fish and seaweed.
- Selenium — protects the thyroid from oxidative stress and supports hormone activation.
- Zinc — essential for the synthesis and release of thyroid hormones.
- Tyrosine — an amino acid that combines with iodine to form T3 and T4.
- B vitamins — support energy metabolism and the nervous system.
A balanced diet rich in these nutrients — plus regular physical activity, good sleep and stress management — is the foundation of thyroid health.
Natural support for optimal thyroid function
Besides nutrition, certain herbal extracts are traditionally used to support the thyroid and the body's response to stress:
- Ashwagandha — an adaptogenic herb shown to support a balanced stress response and thyroid function.
- Schisandra — provides antioxidant protection and supports energy and liver health.
Combined supplements that bring together trace elements, amino acids and botanicals — such as Thyrex Forte capsules from our range — can be a practical daily support for thyroid health.
Frequently asked questions (FAQ)
Are thyroid problems more common in women?
Yes, thyroid disorders are several times more common in women than in men, especially after pregnancy and during and after the menopause. Regular check-ups are especially important for women over 40.
Can supplements balance my thyroid hormones?
Supplements provide the nutrients the thyroid needs to work normally, but they do not replace medical treatment. If you are on thyroid medication, never change the dose without your doctor.
When should I get my thyroid checked?
If you have persistent fatigue, weight changes, temperature intolerance, mood changes or a family history of thyroid disease — ask your doctor for a TSH test.
