Frequently Asked Questions about Thyroid Supplements

About Thyrovanz®

Thyrovanz® is a bovine thyroid glandular supplement which has been lyophilized (freeze-dried) to retain its freshness and potency. The bovine thyroid is primarily sourced from New Zealand, pasture fed cows. We also produce a version with cows sourced from Argentina – these are clearly labelled and never mixed.

Thyrovanz® is used to support thyroid function, energy levels and a healthy metabolism.*

Thyrovanz® comes from New Zealand and Argentinian pasture fed cows that are certified BSE free. The source of thyroid is always marked on the bottle and are not combined. These countries have never experienced any outbreaks of BSE (mad cow disease) and also bans the use of any genetically modified methods of farming and production. In addition, the cattle are not treated with growth hormones.

Some people notice a difference almost immediately, for others it can take a few days or even weeks. Find the correct dose by following the instructions below or in consultation with your healthcare practitioner and you should be able to find the right level for you within a few weeks of starting.

While we have done our best to include as few fillers as possible, some are required to assist the manufacturing process and ensure each dosage is accurate. Aside from the Bovine Thyroid Glandular found in each capsule there is also:

Gelatin, Rice Flour, Magnesium Stearate, and Silica.

Gelatin is what the capsules consist of and is made from gelatin and purified water. The gelatin is sourced from bovine which has been certified kosher.

Rice Flour is used as a filler as required and was chosen due its (relatively) non-allergenic properties.

Silica is used to ensure dosages are accurate and comes from the combination of silicon and oxygen, two of the most abundant elements on earth.

Magnesium Stearate is a natural fatty acid used to ensure encapsulation machinery functions correctly. Our Magnesium Stearate is sourced from palm oil (non-hydrogenated, non-GMO).

These are the only other ingredients in Thyrovanz® with the product being completely and naturally free from gluten, eggs, dairy, soy, nuts, GMO material and with no added sugar.

Thyrovanz® naturally contains a level of T4 and T3, however as Thyrovanz® is classed as a dietary supplement, we do not test for, or list the thyroid hormone levels present within the bovine thyroid glandular. The only natural thyroid products that have listed and standardized hormone levels are prescription medications which can be requested through a medical professional.

It is best to consult with a supportive Doctor or Natural Health Practitioner who can provide medical advice appropriate for these conditions.

If someone is not taking any other thyroid supplement then starting on a low dose of no more than 50mg per day (Thyrovanz® NZ) is usually suitable. This level should be maintained for at least 1 week before increasing if necessary. Continuing in this way until energy becomes stable.

If someone is taking another thyroid supplement and has chosen (with the guidance of a professional) to try Thyrovanz® instead, then it is often suitable to start at a higher dosage that more closely matches what they are currently taking. There are many different products on the market and each one is a little different so there are no exact conversions.

Note: Thyrovanz® Argentina should be considered significantly less effective than the New Zealand version and suitable for people who are either very sensitive, or who need a slight increase in dose.

There are a number of ways to take Thyrovanz®, some of these are:

Early morning: Taking Thyrovanz® as soon as you wake in the morning on an empty stomach. At least 1 hour before food and ideally 2 hours before coffee.

Split dosage: Taking a main dosage of Thyrovanz® in the early morning (E.g. 100mg at 6am), then taking a smaller dosage in the afternoon (E.g. 50mg at 2pm). This can help to achieve a more stable level of energy throughout the day.*

Micro dosing: Dividing your total daily dosage of Thyrovanz® into 3-5 parts and taking small amounts between meals. This can be achieved by emptying 1 or 2 capsules (depending on your dose), dividing the powder into 3-5 even amounts, then popping it into your mouth either as it is or mixed with a small amount of food like peanut butter or honey.

The primary side-effect of Thyrovanz® is over-stimulation which can occur if a person has taken too much at any one time. Signs of over-stimulation are: An increased heart rate or heart palpitations, feeling shaky or even a very mild tremor in the hands, feeling hotter than usual, and sometimes fatigue. It is important to reduce the dosage following any signs of over-stimulation.
The effects of over-stimulation are temporary and should be gone within a few hours, however please seek medical attention if this persists or you have any medical condition.

Changing to Thyrovanz® from another (similar) thyroid supplement can be achieved by one of two ways. Slowly lowering the dose of the old supplement and then slowly adding in Thyrovanz® by approximately the same dose over a number of weeks, or stopping the current supplement one day and starting Thyrovanz® the next. Keep in mind that different thyroid glandulars may have variable potency so your new dosage may be a little higher or lower than before.*

Although the ingredients are essentially the same, the thyroid sourced from Argentina is approximately 50% less potent than thyroid sourced from New Zealand. For this reason we recommend the Argentine product for customers who are either very sensitive to natural thyroid, or who only need a small increase in dosage.*
