Levothyroxine is considered the standard, first-line thyroid hormone replacement medication. Levothyroxine is a synthetic version of thyroxine (T4), one of the two major hormones produced by the thyroid gland. Here's an overview of levothyroxine and other thyroid medications:
- Levothyroxine (Synthroid, Levoxyl, Unithroid, Tirosint)
- The most commonly prescribed thyroid hormone replacement
- Considered the gold standard treatment
- Available as brand name or generic
- Once daily oral tablet
- Over 100 dosage strengths to closely match needs
- Converts to active T3 hormone at cellular level
- Liothyronine (Cytomel)
- Replacement of T3 hormone
- May be combined with levothyroxine
- Used when levothyroxine alone is not effective
- Short-acting so taken multiple times per day
- Desiccated thyroid extracts (NP Thyroid, Armour Thyroid)
- Contain T4, T3, and calcitonin hormones
- Considered natural replacement
- From porcine sources
- May have inconsistent potencies between lots
- Levothyroxine/liothyronine combinations (Thyrolar)
- Single tablet with both T4 and T3 hormones
- For patients unresponsive to T4 alone

Factors in Finding the Best Thyroid Replacement
Several key factors play a role in determining the optimal thyroid hormone replacement for each patient:
- Underlying cause - The best treatment depends on why hormone production declined. Options differ for autoimmune hypothyroidism vs other causes.
- Symptoms - Are there continuing symptoms or sensitivity to medications? Symptoms help guide adjustments.
- Absorption - Various formulations have different bioavailability. Absorption testing can inform which works best.
- Convenience - Frequency and timing of doses impacts adherence. Extended release and liquid forms may help.
- Side effects - Reactions to ingredients may require changing medications.
- Cost/coverage - Out-of-pocket expense varies greatly between options.
- Lifestyle - Diet, gastrointestinal issues, medications for other conditions can all impact thyroid hormone therapy.
- Ongoing monitoring - Regular lab work and dose titrations are crucial for optimal treatment.
Due to these variables, the "best" thyroid hormone replacement depends on the individual. There is no universally superior choice. An experienced endocrinologist can recommend the right medication and dosage for each patient’s physiology and lifestyle.
At Vitality Renewal Clinic, our thyroid specialists guide patients through selecting the ideal thyroid replacement option. We partner with patients long-term to continually adjust dosing to keep hormone levels balanced. Through cutting-edge testing and precision treatment protocols, we achieve healthy thyroid function.
Key Considerations in Thyroid Hormone Replacement Selection
As noted, levothyroxine is considered the standard first-line treatment due to extensive clinical experience using this synthetic T4 formulation. However, finding the right thyroid hormone therapy involves evaluating multiple factors:
Testing
- Thyroid panel - TSH, free T4, free T3, antibodies
- Nutrient levels - vitamin D, iron, etc.
- Pituitary hormones
- Reverse T3 and free thyroid hormone ratio
Symptoms
- Level of continuing hypothyroid symptoms
- Treatment sensitivity and reactions
- Presence of hyperthyroid symptoms
Underlying Issues
- Other autoimmune conditions
- Gastrointestinal disorders impacting absorption
- Medications impacting metabolism
Lifestyle Considerations
- Reproductive stage - pregnancy, menopause
- Diet and nutrition habits
- Consistency taking oral medication
The complexity of thyroid disease means hormone therapy is highly personalized at Vitality Renewal Clinic. Our endocrinologists use advanced diagnostics and precision medicine to determine the optimal course of treatment based on the above factors. We partner with patients to find the right medication, dose, and ongoing care plan for their unique physiology and lifestyle. Contact us to learn more and schedule a consultation.
