Dr. Westin Childs, thyroid specialist and formulator of Thyroid Collagen Complex

The thyroid-collagen conundrum

Does it feel like you’ve aged 10 years since your thyroid diagnosis?

It’s not your imagination; there’s a reason: The rapid depletion of your collagen by your thyroid.

Doing nothing means accelerated aging and issues like wrinkles, hair thinning, slow muscle recovery, and GI issues.

But you can slow down this process by putting back into your body the very compounds your thyroid is taking with 1 scoop of my research-backed collagen supplement designed specifically for thyroid patients.*

Dr. Westin ChildsThyroid specialist and formulator

1

Your thyroid accelerates collagen breakdown

You already have to deal with the fact that your collagen is degrading over time, and thyroid dysfunction accelerates collagen breakdown.[4]

2

You start to age faster and feel older

Collagen represents 30% of the protein mass in our bodies and strengthens and supports the tissues that it is present within.

3

Bioactive collagen peptides help break the cycle

By providing your body with the right combination of peptides that are both absorbed and utilized by your cells, you can slow down this degradation process.*

Why thyroid patients need collagen

Signs your thyroid is depleting your collagen

When this happens, you may start to experience the following signs and symptoms:

Your skin looks drier or more wrinkled

Premature wrinkling or sagging of the skin. A hollowing out of the eyes and cheeks. Increased cellulite.

Your hair breaks or sheds more easily

Brittle hair and nails. Your nails keep peeling or breaking.

Your joints feel stiffer than they used to

Decrease in the flexibility of your tendons and joints. Decrease in overall mobility. Joint pain or muscle pain.

Your muscles are shrinking or losing strength

Atrophy or shrinking of the muscles. Acceleration in the loss of bone strength and density. Decreased circulation.

These problems all stem from the breakdown of collagen but they can all be slowed with the right treatment: Bioactive collagen peptides.[3][5]

Common questions

Frequently asked questions

There’s evidence to suggest that pretty much everyone should take, and would benefit from, collagen supplements for the following reasons:

  • Collagen represents 30% of the protein mass in our bodies.
  • The presence of collagen strengthens and supports the tissues that it is present within.
  • Collagen naturally degrades over time.
  • Collagen supplements have been shown in multiple studies to halt this age-related decline and restore some of its function in various tissues.

On top of these issues, thyroid patients stand to benefit even more given that thyroid hormone helps to regulate the production of collagen and glycosaminoglycans (which act to support collagen function)

So, do you need it?

If you are interested in slowing or halting thyroid-related collagen decline in your hair, skin, nails, tendons, and bones, then yes.

You may think of many of these tissues as tissues primarily related to beauty but don’t forget the importance your bones, tendons, and joints play in your overall health.

Thyroid patients already have to deal with skin, bone, and joint problems from their thyroid, so there’s no reason to add the problem of natural collagen degradation on top of it.

And if you still need more convincing, here are some symptoms that you may already be experiencing a decline in collagen:

  • Wrinkling of the skin on the face
  • The presence of cellulite
  • Brittle hair and nails
  • Joint pain
  • Tendon pain
  • Bone loss
  • Decreased circulation
  • Muscle pain
  • Intestinal problems
  • Slow recovery after injuries

In the simplest sense, Thyroid Collagen Complex contains ingredients that do two things:

#1. Directly provide your body with research-backed collagen peptides.

#2. Support the natural production of collagen with collagen and stem-cell precursors.

These ingredients concentrate collagen in the tissues that need it most.

There are a lot of fancy names and research studies thrown around on this page, but that’s the gist of it.

In order to understand what collagen is and why it’s so beneficial, you need to understand some basics:

Collagen is an abundant protein found in your body, and its primary purpose is to strengthen and support your tissues.

It’s concentrated in tissues like your bones, joints, skin, gut, ligaments, tendons, eyes, nails, and hair.

As you age, collagen levels decline, which causes dysfunction in the tissues where it is found.

This may mean you experience things like bone loss, gut problems, wrinkling on the skin, and so on.

The natural degradation of collagen can be slowed down with the use of collagen supplements.

But there’s one big problem:

Collagen is a very long protein and isn’t very well absorbed when it’s consumed.

To fight this, we have developed ways to take collagen and break it down into smaller pieces known as collagen peptides.

These peptides are amino acid chains that are absorbed much better than the long-chain protein that collagen exists as.

These collagen peptides can be taken in supplement form to support the tissues that contain the most amount of collagen.

Because there are many different types of collagen (28 types), the unique set of amino acids that make up a peptide can differ dramatically from supplement to supplement.

As a result, not all forms of collagen peptides contain the same peptides and not all of these peptides provide the same benefit.

The bioactive peptides sourced in Thyroid Collagen Complex come from grass-fed, pasture-raised cattle that graze in the grasslands of South America and the pastures of North America.

This is somewhat of a tricky question but here’s what we know:

There’s plenty of evidence to suggest that combining protein powder with resistance training helps to increase fat-free mass (which includes total body water, skeletal muscle, smooth muscle mass, and bones) and helps reduce fat mass.

Because many people realize that collagen is a type of protein, they often wonder if they can obtain the same benefits when taking collagen as they can when taking other protein powders.

The answer is maybe.

While collagen is technically still a type of protein powder, the amino acid composition found in proteins like whey and pea differs greatly from that found in collagen.

Muscles require what are called branch-chain amino acids (leucine, isoleucine, and valine) and these proteins are typically not present in collagen.

As a result, even though both compounds contain proteins, they are not comparable in their effects on the body.

Having said that, at least one study showed that, compared to placebo, combining collagen peptides with resistance training did result in an improvement in body composition by increasing fat-free mass, increasing muscle strength, and a loss of fat mass.[5]

So will collagen help you lose weight?

Taking collagen peptides daily and combining it with resistance training may help, but, even in this setting, it would still be preferable to use a plant-based or whey-based protein powder if that’s your goal.

Collagen peptides are certainly better than nothing, but if weight loss is your primary goal then there are better options available.

You can supplements designed specifically for weight loss in my weight loss support bundle.

Thyroid Collagen Complex comes in an unflavored powder so it can be easily combined with water or any other liquid.

My recommendation is to take it with a glass of water each morning but feel free to add it to smoothies, your morning cup of coffee, or add it to juice.

The peptides are even heat resistant up to around 550 degrees Fahrenheit so you can even bake with it!

It can be taken at any time of day but most people take it in the morning.

Feel free to experiment to find what works best for you, just remember to take it every single day.

No matter who you are, collagen is something you’ll want to pay attention to but it becomes even more important if you have a thyroid problem.

Here’s why:

Over time, and due to various factors, your own personal collagen production declines which leads to all of the symptoms mentioned previously.

This problem is amplified if you have a thyroid problem because thyroid hormone plays a role in helping the body to produce collagen.

As a result, thyroid patients are at increased risk for more rapid degradation of collagen and the subsequent symptoms that follow.

Taking collagen peptides in supplement form may help to halt this degradation process and bring back the regular function that collagen provides to the body.

Great question!

We all have to deal with declining collagen because none of us can turn back the hands of time.

But on top of getting older, there are several other factors that can cause premature collagen breakdown.

Factors that do this include:

  • Exposure to ultraviolet rays from the sun
  • Thyroid dysfunction
  • Smoking
  • Alcohol consumption
  • Lack of sleep
  • Lack of exercise
  • Environmental toxins

How is this helpful?

Because if you can understand what causes premature collagen breakdown, you can do your best to combat or avoid these problems.

With that in mind, here are some tips that can help you maintain youthful collagen levels:

  • Wear sunblock and avoid excess exposure to the sun. Get your vitamin D from supplement form and from food instead of primarily from sun exposure.
  • Manage your thyroid adequately with a combination of thyroid medication, thyroid support supplements, and lifestyle changes.
  • Do not smoke!
  • Don’t drink alcohol! Not only will alcohol accelerate collagen breakdown, but it’s also harmful to thyrocytes in your thyroid gland.
  • Ensure you are getting at least 7 hours of sleep each night (though 8 hours is preferred and should be your goal).
  • Exercise at least 30 minutes three to five times each week.
  • Drink plenty of water (somewhere between 64 and 128 ounces each day is ideal for thyroid patients).
  • Reduce your exposure to unwanted environmental toxins by filtering your water and purifying your hair.
  • Take collagen supplements (like the bioactive collagen peptides found in Thyroid Collagen Complex).

Combine as many of these as possible and you should see noticeable improvement within weeks to months.

Each person is unique so it’s hard to predict how any one person will respond but here are some things that other people have experienced with daily consistent use of collagen:

  • A feeling of reduced inflammation in the body
  • Improved gut health and gut function
  • Visual and physical improvement in skin tone and skin quality
  • A reduction in joint pain
  • An improvement in hair and nail quality
  • Enhanced recovery after going to the gym
  • Faster wound healing
  • Improved bone health
  • An overall improvement in general well-being

These are just some of the benefits that others have experienced, but your individual results may vary.

What’s most important is that you stay consistent! Do your best to take it every single day without missing any days.

And if you do this, you can ensure that the bioactive collagen peptides found in Thyroid Collagen Complex will make their way to the tissues that need them most.

Collagen is one of those supplements, much like vitamin D, that does a lot of the heavy lifting in the background which may not always be noticeable.

But it’s safe to say that based on available research, the bioactive peptides are absolutely doing their job behind the scenes and improving your health even if you don’t realize it.

When most people use the term protein powder, they use it as a general term to refer to whey-based protein powders or pea-based protein powders.

And while collagen is technically a protein powder because it contains protein in powder form, it’s definitely not the same as more traditional whey and pea-based protein powders.

Both types of protein powders contain protein in powder form but differ dramatically in their amino acid composition.

And it’s the amino acid composition of a protein powder that imparts all of its benefits.

For example:

Traditional whey and pea-based protein powders contain higher amounts of the amino acids leucine, isoleucine, and valine (known as branched-chain amino acids) which are needed for the stimulation and growth of muscle tissues.

This is why people trying to lose weight or trying to build muscle use these protein powders.

Collagen protein powders, on the other hand, contain higher amounts of the amino acids glycine, proline, and hydroxyproline which are required for collagen production.

Because of their difference in amino acid composition, both types of protein powders provide completely different benefits, and taking one doesn’t negate the need for the other.

In a perfect world, you’d have both a collagen supplement and a more traditional protein powder (preferably pea-based if you have a thyroid problem) to obtain benefits to both collagen production and muscle health.

In order to understand what sets Thyroid Collagen Complex apart you have to understand the difference between proteins, peptides, and amino acids.

These terms are often used interchangeably but they are different from one another.

A protein is a very long and complex compound made up of multiple peptides.

A peptide is a short chain of two or more amino acids.

An amino acid is the smallest and most basic building block used to create proteins.

Your body takes amino acids and links them together to form long and complex compounds known as proteins.

If the compound contains hundreds and hundreds of amino acids, it’s known as a protein.

And if it only contains a few amino acids, it’s known as a peptide.

And it’s at the level of peptides that collagen protein powders can be differentiated.

Thyroid Collagen Complex contains specific and unique peptides (chains of two or more amino acids) that have documented benefits from clinical studies.

These studies have shown that these unique and specific bioactive collagen peptides accumulate in target tissues (such as tendons, ligaments, and bones) to provide their benefits.

What can get confusing is that collagen supplements are often very similar in their total amino acid composition.

But just looking at total amino acid composition doesn’t tell you anything about the peptide composition and it’s the peptides that make all of the difference.

As a result, if you were to just compare the amino acid composition of two random collagen supplements, they would probably look very similar, but they would differ dramatically in their peptide composition which is where most of the benefit comes from.

In short, Thyroid Collagen Complex contains researched-backed peptides with documented benefits whereas most other collagen supplements do not.

Most people notice a change in the quality and texture of their hair, skin, nails, and joints first.

You may find that your skin texture has improved, that it appears stronger or more elastic, or you may see a reduction in wrinkles around your eyes and mouth.

This change in your skin is often visible in the mirror.

Some people notice an improvement in the mobility of their joints and how well they move throughout the day or a decrease in joint-related and/or tendon-related pain.

Other people see improvement in their digestive system and the way that they process foods.

Every single person is different so it’s difficult to give an exact answer here but, on average, it will take a minimum of 6 to 8 weeks of daily use before you notice results.

Because collagen acts on different tissues in the body and because some of these tissues take a long time to regenerate and improve, you may need to continue using Thyroid Collagen Complex for up to 12 weeks or longer in order to obtain its full benefits.

This is not a reflection of the quality of the supplement or its ingredients, but more a reflection of how long it takes tissues like bones, hair, skin, nails, and ligaments to recover and become strengthened.

Based on available data, and patient experience using collagen peptides, here are some guidelines you can use:

  • For skin health: Studies suggest that starting at 4 weeks of daily use there may be a reduction in wrinkles and an increase in skin elasticity and starting at 8 weeks of daily use, an improvement in skin tone/quality.*
  • For joint pain: Reduced knee stiffness and discomfort have been reported in as little as 30 days of daily use.*
  • For cartilage health: Studies suggest that an improvement in cartilage can be seen starting at 3 months of daily use. Continued improvement can be seen at 24 weeks and 48 weeks.
  • For bone health: Studies suggest that an improvement in bone health can be seen after 12 months of daily use.*
  • For gut health: Studies suggest that after 8 weeks of use, collagen may help reduce bloating and improve digestion.

*Results may vary based on your individual situation. The timeframes provided are based on studies.

So, depending on what type of results you are looking for, it may take a while to experience them.

For best results, I recommend staying consistent while planning to use this supplement for the long haul.

The longer you use it, the more your results will build up over time, and the better you will feel.
