Thyrovanz™ Natural Desiccated Thyroid capsules are made from the thyroid glands of New Zealand cows which have been lyophilized (freeze-dried) to retain its freshness and potency. The animals used are all grazed on clean, green New Zealand pasture and raised hormone free.
Thyrovanz™ is classified as a whole food dietary supplement in the United States and hence does not need a prescription. However, its the same natural thyroid that is used in NDT medications like nature throid or armour thyroid. The only difference is that it comes from New Zealand cows. Thyrovanz is a natural thyroid powder and contains the full set of thyroid hormones produced by the body: T4, T3, T2, T1, & Calcitonin.
If you already take a product like nature throid or armour thyroid, then you can start at the same dose.
If you take a synthetic T4 only medication, then establishing a good starting dosage with Thyrovanz is more difficult. You may start with 50mg capsule and watch your TSH levels to adjust to an appropriate dose. For assistance with this seek medical advice from a supportive Doctor.
