Levothyroxine (L-Thyroxine)

Eg. Levoxyl, Synthroid, Levothroid

Levothyroxine provides thyroid hormone when the thyroid is under functioning or inactive.


Surgery is rarely required for hypothyroidism and is only performed where there is presence of large goiters that are impacting esophageal function or potential cancerous lesions.

Herbal support

The adrenals are under extra strain when the thyroid is over or under functioning. Herbal treatments are an excellent supportive adjunct for both adrenal function and stress levels.

  • Kelp
    • Is a good natural source of iodine and other essential minerals. However it is important not to consume too much iodine, therefore kelp should not be taken with iodine supplements or thyroid medications unless under the supervision of your Health Care Professional. Only high quality kelp supplements should be used as some have been found to contain high levels of toxins as found in some seawater.
    • Recommended dose – providing 220mcg iodine per day
  • Withania (Indian ginseng)
    • Withania helps reduce high cortisol levels associated with stress and adrenal dysfunction.
    • Recommended dose – 3000mg – 9000mg per day
  • Oats
    • Oats are a nourishing tonic for the nervous system, aiding in the reduction or cortisol
    • Recommended dose – 1000 – 4000mg 3 times per day
  • Liquorice
    • Liquorice is generally used in combination with other adrenal herbs. It provides mild anti-inflammatory action, acts as an immune system regulator as well as nourishing the nervous system. Liquorice has been known to raise blood pressure, however this is only a side effect of high dose consumption.
    • Recommended dose – 300mg – 1000mg per day in a blend as prescribed by your Health Care Practitioner
