Precision Thyroid Therapy with T3, T4, and Custom Combinations
Personalized thyroid hormone replacement when one-size-fits-all treatments fail.
Understanding Thyroid
Standard thyroid treatment with T4-only medications like levothyroxine doesn't work for everyone. Many patients struggle with persistent symptoms despite "normal" lab values because they can't effectively convert T4 to the active T3 hormone. Our compounded thyroid medications provide precise doses of T3 (liothyronine), T4 (levothyroxine), or customized T3/T4 combinations that match your body's unique needs. We can create any ratio, strength, or delivery method to optimize your thyroid function and help you feel like yourself again.
Key Benefits
Scientific Foundation
Research in the Journal of Clinical Endocrinology & Metabolism has studied patients who may have difficulty converting T4 to T3 due to genetic variations. Studies have explored combination T3/T4 therapy as an alternative to T4 monotherapy. The European Thyroid Journal has reported on patient experiences with individualized T3/T4 combinations.
T3, T4, and Combination Thyroid Therapies
Understanding the different thyroid hormones and how custom combinations can optimize your treatment:
T4 (Levothyroxine)
The storage form of thyroid hormone with a 7-day half-life. Standard treatment, but requires conversion to T3 for activity. We can compound pure T4 in any dose from 13mcg to 300mcg.
T3 (Liothyronine)
The active thyroid hormone that directly affects metabolism. 4x more potent than T4 with faster action. Available in immediate-release (4-6 hour) or sustained-release (8-12 hour) formulations.
T3/T4 Combinations
Mimics natural thyroid output more closely than T4 alone. Common ratios include 1:4, 1:10, or 1:14 (T3:T4), but we customize based on your labs and symptoms.
Time-Release Options
Sustained-release T3 prevents the energy peaks and crashes of immediate-release. Provides steady hormone levels throughout the day for consistent symptom relief.
Your Personalized Thyroid Optimization Journey
We work with your healthcare provider to create the perfect thyroid hormone combination for your unique physiology.
- 1Comprehensive thyroid testing including TSH, Free T4, Free T3, and Reverse T3
- 2Analysis of your symptoms, current treatment response, and conversion markers
- 3Custom formulation of T3, T4, or combination therapy based on your needs
- 4Choice of immediate-release or sustained-release formulations
- 5Careful titration starting with low doses and adjusting based on response
- 6Regular monitoring and fine-tuning to achieve optimal thyroid function
Understanding T3, T4, and Combination Therapies
Discover how personalized thyroid hormone combinations can resolve symptoms that standard T4-only treatment leaves behind.
T4 (Levothyroxine)
The standard thyroid replacement, but not always sufficient alone.
How It Works
T4 (thyroxine) is the main hormone produced by your thyroid gland. It's considered a "prohormone" because it must be converted to T3 to become active. This conversion happens primarily in the liver and other tissues.
Clinical Evidence
While T4 monotherapy works well for many patients, studies show 15-20% don't convert T4 to T3 efficiently. These patients often have normal TSH but continue experiencing hypothyroid symptoms.
Typical Dosing
Typical doses range from 25-200mcg daily. We can compound any dose, including 13mcg, 38mcg, 63mcg, or any specific amount your body needs.
Key Benefits
- Long half-life (7 days) for stable levels
- Once-daily dosing convenience
- Well-studied with decades of use
- Available in precise custom doses
When to Consider This Option
Ideal for patients who convert T4 to T3 well, those new to thyroid treatment, or when stable, consistent hormone levels are the priority.
The Power of Precision Compounding
Unlike commercial thyroid medications that come in fixed doses, we can create any strength or combination you need. Whether it's 38.5mcg of T4, a 1:7 ratio of T3/T4, or a sustained-release formulation, we'll match your exact requirements.
