Thyroid Hormone Optimization (T3/T4)
Thyroid hormones play a central role in metabolism, energy, mood, and cognitive function, and when levels are low or not converting properly, symptoms like fatigue, weight changes, brain fog, low mood, and temperature sensitivity can begin to interfere with daily life.
Our approach to thyroid optimization focuses on restoring the right balance of T3 and T4 using bioidentical formulations that match the body’s own hormones for smoother, more predictable support than synthetic-only options.
Treatment is personalized and delivered through carefully selected oral therapies that include combination T3/T4 (desiccated thyroid), depending on your unique physiology and goals.
With thoughtful evaluation and precise dosing, thyroid optimization can help improve energy, clarity, metabolism, and overall, wellbeing – helping you feel steady, supported, and back in sync.
How Thyroid Hormones Are Produced
Thyroid hormones – primarily T4 (thyroxine) and T3 (triiodothyronine) – are produced by the thyroid gland under the direction of the brain’s hormonal control centers. The hypothalamus releases TRH, which signals the pituitary to release TSH, prompting the thyroid to produce T4 and smaller amounts of T3. Most T3 is created when the body converts T4 into its active form. These hormones regulate metabolism, energy, temperature, mood, and cognitive function.
Symptoms of Low or Underactive Thyroid Function
When thyroid hormone levels are low or not being properly converted, women and men may experience symptoms such as:
- Fatigue or low energy
- Weight gain or difficulty losing weight
- Feeling cold or temperature* sensitivity
- Brain fog or slowed thinking
- Low mood or irritability
- Hair thinning or dry skin
- Constipation
- Slowed metabolism or reduced stamina

Because these symptoms overlap with other conditions, proper testing and interpretation are essential.
Benefits of Thyroid Hormone Optimization
When clinically indicated and carefully monitored, optimizing T3 and T4 levels can help:
- Improve energy and metabolic function
- Support weight management
- Enhance mood, clarity, and cognitive performance
- Improve hair, skin, and overall vitality
- Regulate temperature and reduce cold intolerance
- Support digestive health and hormone balance
Many patients describe thyroid optimization as a turning point in restoring their sense of wellbeing.
Bioidentical vs. Synthetic Thyroid Hormones
Thyroid therapy can include bioidentical or synthetic formulations:
- Bioidentical thyroid hormones (such as T4 and T3, identical to the body’s own hormones) have predictable absorption and compatibility with natural physiology, though some individuals may not convert T4 to T3 efficiently and require combination therapy.
- Desiccated thyroid (a natural extract containing both T3 and T4) may be used for patients who benefit from a combined formulation.
The best approach depends on symptoms, lab values, and how each patient metabolizes thyroid hormones.
Treatment Delivery Options
Thyroid hormone therapy is typically delivered through:
- Oral tablets: the most common and adjustable option, we favor Desiccated thyroid formulations ( Combination T3/T4 therapy): natural extract.
Your clinician will determine the right formulation and dosing strategy based on your unique physiology, symptoms, and treatment goals.
