Absorption and Assimilation of Desiccated Whole Thyroid Powders

Various brands of desiccated whole thyroid powders have given mixed results compared with pharmaceutical thyroid hormones. Some people respond effectively to whole thyroid whilst others do not. Some require a higher than expected dose when compared with the dosage levels of pharmaceutical thyroid hormones previously established.

The main issue with those who do not respond well is most likely a failure to absorb and assimilate the natural thyroid product. In these cases the complete digestive process of whole thyroid is ineffective. The reason for this is most likely poor protein digestion. Whole thyroid is in fact thyroid hormones contained within the protein of the thyroid gland, dried and presented as a nutritional supplement. The proteins of the thyroid gland need hydrochloric acid and digestive enzymes in the stomach to dissolve and enable the absorption of the thyroid hormones in the small intestine.

We therefore recommend the inclusion of enzymes in the supplemental regimen of those who fail to realise the benefits of Thyro Active 2. This will aid in their digestion and therefore assimilation, so as to complete the required function in the body. Multi-Enzyme-Protect is our preferred option; 2 capsules with each Thyro Active 2 dose are recommended. For those who have obvious hydrochloric acid deficiency (as detailed in the article linked below) two teaspoons of apple cider vinegar in a small amount of water may help further with the digestive process. Thyro Active 2 is best taken on an empty stomach, and may be taken 30 minutes before food.

Natural Thyroid comes from healthy livestock.
Natural Thyroid is intended for the natural treatment of hypothyroidism (under-active thyroid). Unlike most remedies for the thyroid gland, which offer benefits for both under and over-active conditions (hyper & hypo); this remedy is intended solely for use in hypothyroidism (under-active thyroid).
If suffering from hypothyroidism, especially if the gland has been under functioning for many years, the use of a desiccated bovine thyroid, such as this, can have tremendous benefit and work far more effectively in the majority of cases than the drug Synthoid /Thyroxine or other forms of drug synthesized T4 hormone.

The pharmaceutical hormone is not exactly the same as that used by the body to maintain correct metabolic rate. The most important hormone to maintain sufficient metabolic energy is T3, although this is in lower quantities than T4 secreted from a healthy thyroid. Most T3 is obtained from T4 conversion. The most often prescribed artificial hormone for thyroid under functioning is T4 (Thyroxine, Synthoid etc.). Many people have a low capacity for this conversion of T4 hormone to T3; this is why many people do not obtain sufficient benefit from taking a T4 only hormone prescription. Taking desiccated thyroid gland can have wonderful effects on a the health of those suffering from hypothyroidism.

Please see the further reading tab above for more in depth information.

Before supplementing with Natural Thyroid one should establish the suitability of the product and a need for the product with these 2 simple self administered tests 

  1. Barnes Basal Body Temperature Test

  2. Simple Blood pressure test

The first test will indicate the state of thyroid function and hence indicate a need (or not) for Natural Thyroid whilst the second test indicates adrenal sufficiency/deficiency. The reason for this second test is that if adrenal deficiency is indicated, then Natural Thyroid should be deemed unsuitable until such time as that deficiency has been resolved. Not doing so can cause quite serious health issues. Taking Natural Thyroid, especially during the several week adaptation period, will demand higher than normal levels of bodily hydrocortisone (cortisol) (the adrenal hormones, especially hydrocortisone, are the coping/adapting hormones), if the required cortisol is not available then one can 'crash'. Examples of this are serious fatigue, flare up of pre-existing auto-immune disease (including asthma) and even failure to deal with infections.

A good bodily supply of hydrocortisone (via Adrenal MAX Support if bodily supply is deficient) is essential before using Natural Thyroid.

Natural Thyroid Directions:

It takes a few weeks of taking Natural Thyroid for the long acting T4 levels to build up; one reason for the generally recommended gradual raising of dose over a few weeks.

Typically most people need to build up over several weeks to a level between 1Ĺ and 2Ĺ capsules daily.

Begin by taking half to one capsule daily*. Generally it is found to be safe to start at a half capsule daily (providing the heart is not weak) and to hold at that dose for 3 to 14 days (an absolute minimum of 3 days).

*Some very sensitive individuals may even find half a capsule daily overly stimulating in which case start at ľ capsule daily.

Increase the amount you are taking by half capsule and maintain that amount for another three to fourteen days before increasing again; until you feel you have achieved your optimal level.

Each week, continue to test oral temperature and pulse for three days in a row per the Barnes Basal test outlined in the link above and take the average reading. If the temperature and pulse are still low, continue to increase dosage.

If you feel you have exceeded a tolerable dose* stop thyroid for one day and resume at a slightly lower dose.

*The symptoms of taking too much Natural Thyroid are a nervous or jittery feeling, similar to having drunk too much coffee. For some, these symptoms include palpitations (increased heart rate).

Do not rush the process, and do not exceed five capsules daily. If you have reached five capsules a day and still feel you need more support then other metabolic energy issues need to be worked on. Please click here

Note: Children need less and respond faster. Also, until the age of about eight years, a childís pulse is high, around 110 beats per minute, so the only reliable test in young children is the temperature.


It is important to keep a detailed journal or record of Natural Thyroid use so gradual improvements can be noticed. This should consist of dosage and description of how you feel and indicating when the dose has been increased etc. 

How long will it take to see any results?

Some people report immediate results while others report more gradual improvement. It is an important part of the process to allow the body time to adapt. In general, the lower the basal temperature, the more support one may need and the longer it may take to feel better. Each person needs to find the right level for their body. Keep in mind that it is possible for that amount to vary. Many report needing less support if they travel to warmer climates and more if they travel to colder climates. The symptoms of thyroid and adrenal imbalance can be similar. Click here for a more detailed article with graphs.

Hypothyroidism can lead to low blood sugar, increased adrenalin and increased cortisol. Although many of those with hypothyroidism conversely experience low cortisol output due to adrenal insufficiency. It is interesting to note that cortisol is required for efficient use of thyroid hormones by all of the bodyís cells. Excess adrenalin in the long term can cause a racing pulse, irregular, or fast heart beat, anxiety and panic attacks, hypertension and can eventually lead to heart disease. Adequate thyroid function is necessary to control adrenalin at normal levels. The higher your adrenalin, the slower you must increase your dosage to avoid symptoms of excess adrenalin. As Natural Thyroid is slowly increased, adrenalin slowly decreases to normal. Some people can only tolerate ľ capsule of Natural Thyroid at first and can only increase by ľ capsule doses.

Higher dosages are needed in those who eat excessive unsaturated fats such as bean, seed and nut oils, which inhibit thyroid function.

Symptoms of Hypothyroidism

Some of the symptoms of hypothyroidism can be: depression, low energy, fatigue, frequent infections, chronic headaches, circulatory problems, chronic skin problems, poor memory and/or concentration, eczema, psoriasis, asthma, excessive weight, irregular menstrual periods, neurosis, irritability and hair loss amongst others. If the outer 1/3 of your eyebrows do not grow then hypothyroidism is probable.


If you suffer from weak adrenal glands or adrenal insufficiency it is unwise to take Natural Thyroid or any thyroid hormone without first supporting adrenal hormone output with a remedy such as Adrenal MAX Support (cortisol) and/or DHEA. As soon as you have established a dosage regime for adrenal hormone(s), if needed, you can start with Natural Thyroid. If cortisol /DHEA is low due to adrenal insufficiency; taking Natural Thyroid will increase the metabolic rate as it should do. This will, for a time (maybe months), increase the need for circulating cortisol/DHEA. Without the support of supplemental cortisol and/or DHEA the demand on the adrenal glands could cause further enervation resulting in dangerously low levels of cortisol/DHEA. If you are unsure if you have low adrenal hormone output, read the articles for these products (as linked above) for information on how to ascertain adrenal hormone output (especially cortisol). If you experience a racing pulse with low temperature, itís often due to excess adrenaline, not hyperthyroid function.

Dietary Considerations in Relation to Thyroid Function

Avoid thyroid inhibitors such as unsaturated oils. Coconut, palm, butter, ghee and olive oil are the only acceptable oils to use. If taking any polyunsaturated oils they should be taken only in teaspoon amounts and then only unheated, raw, with no chemical processing. Avoid soy products like tofu, soybeans, soy milk (some fermented soy is okay such as Miso or Natto). Avoid raw cruciferous veggetables such as cabbage, broccoli, cauliflower; these must be cooked. Avoid Fluoride in water, toothpaste, etc., Avoid all excess estrogen and estrogenic substances such as birth control pills, ERT, herbal estrogens and pesticides. Eat thyroid stimulating foods such as adequate protein, complex carbohydrates and ensure the use of only full spectrum, unprocessed salts such as Celtic Ocean Sea Salt

A note on Body Temperature and Pulse

Most people who are hypothyroid have a daytime oral temperature of less than 98.6oF/37oC and a resting pulse lower than 75-85. A few patients have an abnormally high pulse due to excess adrenalin, the bodyís way to compensate for sluggish thyroid function. Many hypothyroid people have from 10% to 40% excess adrenalin. Thyroid hormones will make the tissues more sensitive to adrenaline and some people will feel hyperactive at the beginning due to increasing tissue sensitivity to adrenalin. But, as the tissues become more sensitive to adrenaline, less will be produced and hyperactivity will disappear. It takes several weeks or months to calm the adrenal glands.

Natural Thyroid has both a cumulative as well as a healing effect. So it is wise to keep track of your oral temperatures and your resting pulse. Donít guess. Low and high thyroid symptoms can be identical (e.g. insomnia, restlessness, and headache).

Side Effects

Patients with high blood pressure or colon problems may experience a headache due to increased circulation and small changes in blood pressure or colon pressure. If this occurs, stop the Natural Thyroid until the headache has gone, and then resume taking. As blood and colon pressure normalises, headaches will cease. If itís a colon headache, work on correcting constipation first, then go back to working on optimizing your temperature and pulse.

I have been buying them for several years now for myself and for my daughter to use.  I like that they do not have corn or cornstarch in them because I canít use the prescription natural dessicated thyroid available in Canada because they contain corn and make me break out into eczema.  That is why I try to buy my thyroid supplements from other sources rather than get my prescription ones.  My daughter says she likes the reasonable price compared to another brand that we can get from the USA, which are very expensive.


I would like to write about my experience with this product. I started using this product because I was reacting to fillers on every other thyroid supplement I took. It made me feel the most even in terms of mood and energy. Since stopping this product, because it was out of stock, I cannot get the same feeling or thyroid level with other over the counter desiccated thyroid supplements. My doctor and I had just figured out my correct dose and thyroid levels with this product when it was discontinued, throwing me for a loop. My doctor also said that it was the best T4 to T3 ratio she had seen in an over the counter desiccated thyroid and does not want me to try the porcine one because she believes it is a worse ratio than the bovine was. I also react to porcine products and foods, leading me to believe I might also react to a porcine desiccated thyroid. I told others about this product telling them they should give it a try since it worked so well for me. Hopefully, you find a way to bring this product back!


My wife had Stage 3 thyroid cancer. She no longer has a thyroid. This has caused a number of problems for her. Most important being to find a reliable source of thyroid she can take, given that she is allergic to the synthetic versions! Thyro Acitive has been a critical component in helping her stabilize and being able to maintain a "somewhat" normal life. Please don't discontinue it. Thank you.


I was always very pleased with this product and would have reordered if it had been available. It is very difficult in the uk to find these natural products and I do not like taking thyroxine. I have had to order Metavive 1V instead but they donít give T4/T3 measurements and I donít know what effect this will have.


I use this product every day and have done so for quite some time now and am very grateful to you for making it available. I cannot take normal Thyroxine as it is very toxic for me. I would be very disappointed if you discontinued it, unless there was a similar product to replace it. I would not know where else to get something similar without a prescription.


I really value this product and find it very helpful in keeping my thyroid in balance, and my energy levels good. I have ME/CFS and an underactive thyroid, and this supplement is very useful. I hope you will decide to re-stock it, as I have not been able to find an equivalent product available without prescription in the UK.


I have taken these tablets for several years, and know someone who is also taking them. They have been a lifesaver for both of us, and i don't know what we would have done without them. Recently we have tried the porcine tablets, and found them equally as useful. I would definately recomend them. Unfortunately during these uncertain times the only problem we found was getting a regular supply, due to the lack of flights. 
Also because we were taking them regularly we would have loved if you had a subscribe button so that the tablets get sent out automatically every month.
Thanks for your support, these tablets deffinately help. 


I have been taking the bovine Thyro Active product for several years. However, I am not sure I can offer a whole lot of light regarding the effectiveness or lack of effectiveness of your product because I never took pharmaceutical grade thyroid either synthetic (Synthroid) or dessiccated (Armour Thyroid). There is another product that I believe is called NatureThroid but I have never had that either. I have no prior experience to compare with experience of Bovine Thyro Active. However, I can say I really, really want you to continue to offer the bovine thyroid product because I choose to not consume any porcine product. The reasons for that are both biochemical and religious. Regarding absorption, I regularly take enzymes. I also work with a healthcare practitioner every two weeks who stays on top of issues like absorption and immune system challenges etc. Regarding dosage, if you are a pre-menopause patient, dosage of everything is a challenge. I call it the female ding-dong syndrome. Post menopause the ding-dong is less spiky but still a challenge. My practitioner does adjust the dose from time to time. I like your product very much because the quality is very high, the price is one I can afford and it is a bovine product. Hopefully you have a lot of customers like me who successfully use your product and want you to continue to provide it!

Please DO NOT discontinue this product.  It is wonderful!! I am an FDN-T (in training) and my clients, my husband and myself all use Thyro-Active and love how well it works. Itís natural, contains the perfect balance to t4 and t3, and doesnít require a doctorís prescription to obtain.  Very few clients, friends, and family members want to or can go visit a doctor during these trying times. Yet most know they have hypothyroidism or a need to supplement with Thyro-Active until their adrenal dysfunction/cortisol issues are resolved. I have done my research and your product by far is the best out there to meet the critical needs of people who need help with their thyroid issues by using Thyro-Active. I feel confident recommending Thyro-Active because it is raw bovine hormone, naturally sourced, no fillers, or artificial ingredients. I donít have to worry about an adverse reaction to an unwanted adjuvant that might affect myself or my clients. It is nearly impossible these days to find a natural, affordable product that actually performs as advertised. Thyro- Active is ONE of those rare products. Please keep this product. It is very much needed. So much has changed in lives of most people, the last thing those people need now is to loose a product that helps them keep their body in a balanced state.


I love this product and have been waiting patiently for it to be back in stock. When I was out a few months ago, I felt awful. It keeps my levels where they need to be. Please continue to carry it or tell me where I can get it, if you choose not to stock it. Thanks


Please continue to stock this amazing item which helps me to manage my hypothyroidism
