A Natural Solution

Armour Thyroid is a brand name of a natural desiccated pig thyroid manufactured by Forest Laboratories and is used extensively for treatment of low thyroid conditions. This is composed primarily of iodine.

This is the most well known and oldest manufacturer on the market which produces desiccated thyroid. Over the years, there has been tremendous treatment success because it has the same hormones as your own thyroid.

Armour Thyroid Supply

Armour Thyroid has been reformulated and the results are in from those trying to take it - it's not good.

The reformulated product is now high in cellu­lose which causes a return of the hypothyroid problems with additional stress on the adrenals.

Some people have tried crushing the tablets to break down the cellulose. A few are able to tolerate this with no problem and can mask the taste with sugar which helps in absorption.

Naturethroid was also reformulated with the addition of cellulose. Crushing the tablets and adding sugar has helped some individuals.

Canadian Armour Thyroid Alternatives

The most readily available source today is through ERFA Canada Inc.

Many have found that the best results are obtained by taking the tablet sublingually for maximum absorption.

Through the graciousness of the FDA, US citizens are allowed to order this.
