Such variations in product potency present actual safety and effectiveness concerns. However, no currently marketed orally administered levothyroxine sodium product has been shown to demonstrate consistent potency and stability and, thus, no currently marketed orally administered levothyroxine sodium product is generally recognized as safe and effective.How Does Synthroid Differ From Natural Thyroid? Synthroid contains Thyroxine also called T4, which is the same hormone produced by the thyroid gland. Levothyroxine is a generic form of Synthroid. Strictly speaking, Synthroid is bio-identical, even though it is synthetic.
In patients with selenium deficiency, this enzyme is not working properly, and many of these patients have an inability to convert T4 to T3. Selenium supplementation is useful here. In my experience, most patients feel much better, with more energy, and relief of symptoms when switching from Synthroid to a natural thyroid such as Naturethroid.As a matter of fact, these preparations do not report their dosage strength in milligrams, but rather, in grains of thyroid. This is because; they don't really know the milligram equivalent in each dose.
There is no way to be certain of this, and patients on these preparations often have fluctuating hormone levels, which may or may not result in symptoms. Regardless of symptoms, the goal of replacement therapy is to keep the hormone levels as stable as possible.Viewer Question What is your feeling regarding natural vs. synthetic replacement therapy in hypothyroid situations? Armour, for example vs. Synthroid? My daughter is exceedingly sensitive to most medications and is in the process of being diagnosed for possible Hashimoto's.
Natural Thyroid pills are made from desiccated porcine (pig) thyroid glands which contain Thyroxine (T4 T3, T2, T1 and Calcitonin. Economics of Thyroid Pills and Synthroid. As of 2005, 10 million people in the U.S.Viewer Question. What is your feeling regarding natural vs. synthetic replacement therapy in hypothyroid situations? Armour, for example vs. Synthroid?
Dosing is also based on the assumptions that each gland has equal amounts of hormones as the next gland, and that the ratio of T4 and T3 (the more active hormone) are similar and constant in each gland from the pigs.Unlike Nature-Throid and Westhroid, synthetic medications have often been recalled due to batch inconsistencies. Yet most doctors are led to believe that desiccated thyroid is unstable. To ensure that Nature-Throid and Westhroid Thyroid USP tablets are consistently potent from tablet to tablet and lot to lot, analytical tests are performed on the raw material (Thyroid.
Levothyroxine is the most common form of thyroid hormone replacement therapy. Prior to the availability of the pure levothyroxine, desiccated animal thyroid extract.(9-10) Change in Armour Formulation Armour changed their thyroid tablet formulation in 2009, and we have seen reports from patients who are not happy with the new formulation.

Chapter Three.

Important Point: Natural thyroid medication is clinically superior to T4-only thyroid such as levothyroxine and Synthroid. Mary Shomon on Natural Thyroid vs. Synthetic An article by Mary Shomon in the Townsend letter explains why natural thyroid treatment is better, that Synthroid and Levothyroxine are unstable, with dosage varying according to batch, and subjected to multiple.Lots manufactured in 2003 were found to have lost potency 2 years later in 2005, so Forest Labs recalled all tablets made in 2003. Since it was 2 years later, very little product from these lots was still in distribution, so it was actually a small recall.
Let's start by doing a little research. If the above doctors answer is true, we should expect to find that the FDA. HAS NEVER recalled Synthroid because of problems with stability or potency, and we would expect that the FDA.Synthroid contains T4 which is inactive, and must be converted to T3 by the body for it to work. This conversion is done by a de-iodinase enzyme, which is a selenoprotein.
Janie suffered for years with low thyroid symptoms even while on Synthroid, and had a dramatic recovery after converting from Synthroid to natural thyroid. Her book makes a strong statement as an advocate for natural thyroid medication.(14) Our Program: For.Thyroid hormone is used in two situations: to replace the function of the thyroid gland, which is no longer functioning normally (replacement therapy) and.
There is another comment that should be made. With all the issues surrounding "mad cow disease" and other ailments, I personally am reluctant to offer animal based therapy to patients when a safe effective well studied synthetic preparation is widely available.Millions of Americans have enjoyed ham sandwiches and pork products for decades without a single case of Mad Cow Disease ever reported. This essentially invalidates the fear of Mad Cow Disease as an argument.
Take thyroxine.

L.H. Doctor's Answer While it is reasonable to assume that synthetic medications are less desirable than natural counterparts, in this case- natural thyroid hormone replacement is definitely not an ideal solution for the vast majority of people.This is much easier to achieve with synthetic preparations such as Levoxyl and Synthroid. These preparations come in a vast number of standardized doses, allowing for minute adjustments in hormone dosing.
Here is a typical response to a question from a reader on a popular medical information web site called t. The readers question is: Dear Doctor, what is your feeling regarding natural vs.I hope this helps answer any questions you may have. Thank you for your question. From the Medical Author: The Mainstream Doctor M.D. "Natural Thyroid is Not an Ideal Solution"?! This nonsense really makes my blood boil and my eyes pop out of head.
HAS recalled natural thyroid pills because they are unstable, and vary in potency. So let's ask the FDA about this. What do we find? In reality, the FDA says Synthroid is unstable and varies in potency, while natural thyroid from RLC labs HAS NEVER been recalled for instability or variation in potency.Here's why: Armour thyroid is derived from desiccated pig (porcine) thyroid gland. A number of years ago, these natural preparations were our only alternative. Replacement with desiccated thyroid creates dosing problems because there is no way to standardize the exact amount of the dose for each batch.
