What is the difference between T3 and T4 thyroid hormones?

T4 (thyroxine) is the storage hormone that your thyroid produces in larger quantities. T3 (triiodothyronine) is the active hormone that your body uses. Most of your T4 is converted to T3 in your tissues. Some people have difficulty with this conversion, which is why combination therapy or T3-only formulations may be prescribed.

How long does it take for thyroid medication to work?

Most people begin to feel improvements within 2-4 weeks of starting thyroid medication, though full benefits may take 6-8 weeks. This is why follow-up blood tests are typically done 6-8 weeks after starting or adjusting medication, allowing time for hormone levels to stabilise.

Can compounded thyroid medication be more effective than standard prescriptions?

Compounded thyroid medications allow for precise dosing, custom combinations of T3 and T4, and removal of fillers or dyes that some people react to. This personalisation can improve symptom control and reduce side effects for many patients, particularly those who haven't responded optimally to standard formulations.

Do I need to take thyroid medication for life?

For most people with hypothyroidism, yes. However, some causes of thyroid dysfunction (like temporary thyroiditis or medication-induced changes) may be reversible. Your prescriber will monitor your thyroid function regularly and adjust treatment as needed.

What blood tests are needed to monitor thyroid health?

The most common tests are TSH (Thyroid Stimulating Hormone), Free T4, and Free T3. Some practitioners also test for thyroid antibodies (TPO and TG) to check for autoimmune conditions, and reverse T3 to assess conversion efficiency. Your doctor will determine which tests are appropriate for your situation.

Understanding Thyroid Function & Treatment

The thyroid gland regulates metabolism, energy levels, and body temperature. Learn about thyroid disorders and personalised treatment options.

Overview

The thyroid is a butterfly-shaped gland in your neck that produces hormones affecting nearly every organ in your body. When it doesn't function properly, it can lead to a range of symptoms from fatigue to weight changes.

Common Signs & Symptoms

Unexplained weight changes

Fatigue or low energy

Temperature sensitivity

Changes in heart rate

Mood changes

Hair loss or thinning

Common Thyroid Conditions

Hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid) are the most common thyroid disorders. Hashimoto's disease and Graves' disease are autoimmune conditions affecting the thyroid.

Compounded Thyroid Solutions

We can create personalised thyroid hormone formulations including T4, T3, or combination therapies. Custom dosing allows for precise adjustment based on your individual needs and lab results.
