T4 and T3 Prescriptions

T4 and T3 Prescriptions

Most doctors will prescribe T4, the inactive form of thyroid hormone, commonly known as Synthroid and Levothroid. T4 is the typical thyroid replacement seen in traditional medicine. The liver and small intestine are responsible for converting the T4 to T3 - the usable form of thyroid hormone. If these organs are toxic or imbalanced from diet, environment, emotions, or infections, the body has a hard time converting T4 to T3, and fatigue will follow.

Instead of using the TSH levels (thyroid stimulating hormone) as an indicator, many integrative health practitioners utilize the free T3 levels - the usable form of thyroid hormone. Free T3 is the hormone that is used for actual energy production, our quick energy. T4 is the slow burner; it is waiting to be turned into free T3 to be used for quick energy production.

Research by the New England Journal of Medicine reported that T4 was not as effective as free T3 to help patients with thyroid disorders. Many doctors who prescribed and utilized bioidentical hormone replacement therapy or whole glandulars from animal sources have been criticized and brought before medical boards-even with sufficient data supporting their case. However, much documentation has shown that bio-identical hormone therapy and glandulars are positively affecting hypothyroidism. Patients report higher energy, more stamina, hair growth and retention, better sleep, increased immune, and improved sleep.

Hormone replacement medications:
  1. Armour thyroid
  2. Nature-throid
  3. Westhroid
  4. MP-thyroid
These have been highly effective for many of my patients, but I am mindful if they do not work efficiently. If they are not working well for you then ask your primary care if switching to a different form would be best for you. Many times I ask the patient to check the binders and fillers of the medication to make certain there is no components they are sensitive to in the medication.

For example, a patient of mine who is highly sensitive to corn found out that corn starch was a component of the medication to bind it together. Finding a practitioner who is well vested in finding a compatible prescription for your body type is highly recommended-whether it be muscle testing, bio-feedback, meridian point EAV testing, or any other type of compatibility testing. Search these practitioners out, and see if you are comfortable with the techniques.

When do you know you need a hormone replacement medication? That is truly up to you and your doctor, but usually it occurs when your thyroid levels are extremely low. If your levels are on the borderline of low, a simple supplementation protocol of vitamins, minerals, or just iodine may be all that is needed.

When do you know you have taken too much hormone replacement medication?
  • sweating
  • overheating 
  • heart palpitations
If you experience these then tell your doctor and see if reducing your dosage is recommended.
