Mega Nutrient Adaptogen

Even seemingly healthy, normal thyroids need specific nutrients to run efficiently and prevent metabolic slowdown that occurs when calories are reduced, which is why our weight loss comes to a screeching halt. No matter what you do, you can't seem to lose weight. All-natural Advanced Thyro-Boost contains the specific nutrients our thyroids need in a micro-active absorbable form with a 98% absorption rate, making it easier to lose weight and ease anxiety and stress that can play a role in weight gain, lack of weight loss, and excess belly fat. It improves memory, mood, and metabolism!

LynFit Thyro-Boost is a unique, fresh, mint-flavored, custom-blended liquid supplement designed to help fight symptoms of an underactive thyroid while reigniting your metabolism, improving digestion, and nutrient absorption.

What Makes LynFit Thyro-Boost Different?

Twenty most effective powerhouses that have been proven effective in helping underactive thyroids regain function

After decades of research, we have chosen the 20 most effective natural powerhouses to help underactive thyroids regain function so you look and feel better fast. 

Thyro-Boost is one of the best ways to boost your immunity, in addition to thyroid support naturally. White blood cells are our body's first line of defense. When they are functioning properly, they recognize pathogens and fight off infection. Immune Boost helps nourish and support white blood cell function so they can adequately create antibodies that fight against bacteria, viruses, and other potentially harmful invaders.  

Weight gain and sluggish, slow weight loss are often the result of a disruption in thyroid function, whether from a reduction in calories, age, hormonal imbalance (affecting both men and women), or chronic stress. Thyro-Boost’s liquid formula is easier to absorb than tablets, and its natural botanical extracts (backed by scientific research) and nutrients nourish and protect the thyroid, boosting its function naturally and safely.

Thyroid medication only treats the symptoms of hypothyroidism and doesn’t address the underlying issues that caused it to slow down in the first place. Even if you take thyroid medication, you might not lose weight or feel better. That’s why nourishing the thyroid with the specific nutrients it needs is the best way to get it moving again.

An underactive thyroid affects every aspect of your life, such as the lack of energy and excess weight you can't seem to lose. No matter how hard you try, that may leave you drinking cup after cup of caffeine-loaded beverages that negatively affect your weight loss. You may also crave the wrong types of food, which can leave you depressed and hopeless. These can leave you feeling helpless, and eventually, you stop trying, thinking it’s out of your control. LynFit Nutrition specifically designed Thyro-Boost with all this and you in mind.

The #1 reason people cannot lose weight and diets stop working is due to their thyroid slowing down as a result of the caloric restriction that's necessary for weight loss. So what are you supposed to do? Boost it to keep it functioning optimally so you begin losing weight again—and keep it off.

Advanced technology and clinically researched ingredients that are inspired by nature

LynFit hand-selected each of the 20 natural botanical extracts that are superfood powerhouses that have been proven to be highly effective when it comes to:

  • Safely boosting metabolism
  • Helping to increase levels of iodine vital for your thyroid
  • Helping energize your body and battle fatigue
  • Supporting the production of T3 and T4 hormones by nourishing the thyroid
  • Increasing the burning of stubborn body fat
  • Improving mood and focus
  • Easing anxiety and reducing cortisol levels
  • Combating constipation
  • Helping to alleviate and prevent dry skin and hair loss associated with hypothyroidism
  • Balancing and optimizing delicate hormonal imbalances that affect both men and women
  • Providing a rich source of antioxidants
  • Detoxifying and cleansing the body 
  • Boosting immunity
  • Providing a highly absorbable, fast-acting, easy-to-take liquid supplement

LynFit uses advanced technology and chooses clinically researched ingredients inspired by nature so you can feel good about what you put into your body! We use the most advanced methods, such as a cold-extraction process, to refine these ingredients' most potent, bioavailable form possible. Then, we filter them into a liquid extract formula for maximum absorption and efficacy.

While most thyroid supplements give you synthetic Tyrosine (a chemical form), LynFit uses Spirulina. These natural forms of blue-green algae have the highest tyrosine concentration of any other natural source. This high-quality Spirulina also has much more. Spirulina is also a good source of:

  • Protein, Vitamin B1, Vitamin B2, Vitamin B3, Copper, Iron, Iodine, Magnesium, Potassium, and Manganese
  • A balance of Omega-6 and Omega-3 fatty acids
  • Rich sources of antioxidants

LynFit's proprietary process

Step #1: Provide the nourishment your thyroid needs to function from natural sources using pharmaceutical quality and dosing using extracts that have been cold extracted (heat damages the quality)

We combined the top three essential minerals, such as iodine, selenium, and tyrosine, to nourish your thyroid and make it healthy again. We set out to find the most nutrient-rich herbal and plant sources of these three super-hero ingredients, sought out the highest quality you can find in the United States only, and made sure they were handled with care, extracted only under the purest, most advanced conditions.

LynFit used only cold extraction to ensure the ingredients you need to feel better are not destroyed in the processing. This was the best way to get these ingredients' potent, bioavailable, concentrated form.

We use only the best sources and will never cut corners. These nutrients weren’t artificially created in a lab and formed into a tablet because we know that hypothyroid bodies don’t have the best digestion, so you rarely get what your body needs the most. That’s why we went the extra mile and made it liquid.

Step #2: Enhance thyroid hormone output with Coleus forskohlii

Coleus forskohlii is an amazing ingredient that supercharges the thyroid, enhancing hormone output that tends to slow down when calories are reduced (especially when dieting to lose weight). It tricks your body into acting like a thin person and teaches it to burn more calories.

Because Thyro-Boost is a liquid extract, it easily soaks up the iodine for nourishment, so it builds up your thyroid to give it the fuel it needs to send thyroid hormones throughout your entire body. Feeding your thyroid is like fertilizing your garden—it helps everything move a little faster.

Step #3: Balance and optimize delicate hormone balance with Ashwagandha

Ashwagandha is known as an 'adaptogenic' herb. Studies confirm that it has a balancing effect. It has been known to balance cortisol (the fat-storing, weight gain stress hormones), reduce fatigue, boost brain function, and even help alleviate depression and improve mood.

In today's world, we can’t control what goes on around us, and it's a necessary time to stay strong, especially when protecting our health and keeping our bodies healthy and strong. Immune Boost is one of the best immune-boosting nutritional supplements because it helps the body adapt to stress, which helps keep it in homeostasis.

  • Helps build your body's defense against viruses, colds, and the flu, as well as other diseases, without the harmful side effects
  • Helps your body adapt to stresses and seasonal stressors 
  • Helps support white blood cell function (white blood cells are the cells of the immune system that are involved in protecting the body against infectious disease and foreign invaders)
  • Quick absorption for high efficacy*when taken under the tongue

Our immune system is like the military... it comprises a network of cells, tissues, and organs that all work together synergistically, protecting our bodies against outside influences and threats. Like the military, our immune system has different branches, each serving a specific and unique function when protecting our body. The stronger the immune army, the healthier we are. Immune Boost provides our bodies with the nutrients they need to stay strong and healthy, defending them against the ravages of stress.

The remaining parts of the immune system, such as the bone marrow (where white blood cells are produced), and our lymph nodes (have two jobs: One to produce infection-fighting cells. The other is storing infection-fighting cells throughout the body, so we have a full tank should we need them ready to fight.

The spleen plays a vital role in helping to control the amount of blood in the body and cleans out old or damaged blood cells from the body. With all these functions and hard work in our bodies, we must ensure they consistently get the nutrients they need daily.

While vitamin C is good, it can't be an entire army to prevent the colds, viruses, and diseases of today's world. They differ from ten years ago due to travel, stress, and our bodies being over-caloried, yet lacking essential nutrients.

If you're losing weight and/or working out or healing from an injury or surgery, your nutritional needs are increased, and that's why you don’t want just any old store-bought immunity booster supplement.

When it comes to your health, quality and purity matter the most, as well as a product's strength. That's why LynFit and its medical mentors create all our products in clinical strength. They are also created in the amounts that research proves to work—nothing more and nothing less.

What's In It?

Nutritional information


Thyro-Boost combines the top natural botanicals that are the best immune helpers, and when combined like this formula, it works ten times harder, thanks to synergy. This formula includes the following organic, non-GMO herbs:

  • Iodine: It's the fuel that powers the thyroid that powers our entire body, including our immune system. A weak thyroid = a weak immune system.

  • Selenium: This antioxidant lowers oxidative stress in our bodies, which reduces inflammation and improves immunity.

  • L-tyrosine: This amino acid is a building block for brain signals (our brains tell our bodies to fight or get sick) and helps maintain a healthy nervous system.

  • Stinging Nettles: This incredible extract inhibits inflammation that can trigger seasonal allergies and block histamine receptors, stopping immune cells from releasing chemicals that trigger respiratory and/or allergy symptoms.

    The strain we use in Immune Boost (Thyro-Boost) contains an anti-inflammatory substance that suppresses several cytokines (cytokines are molecules that signal and mediate immunity) in inflammatory joint diseases, which means it helps any condition that ends in “itis.” 

    Stinging nettles are high in potassium, calcium, and magnesium and great for gout. 

  • Kelp Thallus: Kelp is high in antioxidants, including carotenoids, flavonoids, and alkaloids, which help fight against disease-causing free radicals. It also helps fight and kill cancer cells by activating our immune system. Thanks to its high antioxidant levels, which also include vitamin C and minerals like manganese and zinc, it helps combat oxidative stress.

  • Spirulina:  Spirulina is a blue-green algae super-rich in antioxidants, vitamins, minerals, and other health-building nutrients. Spirulina has been shown to engulf bacteria, increase our body's antibody response, and send a message to our brain to release and increase its natural antibody response, improving the activity of killer cells that destroy infected cells.

  • Fenugreek Seed: Besides lowering blood sugar and cholesterol, which helps boost immunity (high blood sugar and high cholesterol damage), it also reduces blood pressure and inflammation, relieving pain. A healthy body means a more robust immune system. Fenugreek also helps with appetite control.

  • Sage Leaf: Sage leaf is well known for its antibacterial properties, antioxidant effects, and anti-inflammatory properties. It's traditionally known to help ease congestion and respiratory issues, help reduce cold, flu, and virus symptoms, and shorten the duration and servitude of illness, should you end up getting sick. Sage leaf also strengthens immunity. 

  • Ashwagandha Root: Studies show that ashwagandha increases the activity of our natural killer cells, which are immune cells that fight infection and keep our immune systems healthy and strong. Ashwagandha also helps decrease inflammation.

  • Shepherd's Purse:  Shepherd's purse has been used successfully in folk medicine for centuries in Asian and European medicine to boost immunity in all areas. It has unique properties that can help with dysentery, menstrual disorders, and fever. It's not limited to these and is a star player regarding circulatory issues, heart issues, headaches, and diarrhea. 

  • Irish Moss: Irish moss is loaded with potassium, which is excellent for dissolving phlegm that clogs our airways and bodies (congestion is not limited to the nose). The congestion gets infected, and bacteria love to feed off that. It also contains vitamin C, antioxidants, and anti-viral and antimicrobial agents to prevent infections.

  • Dulse Moss: This sea vegetable is loaded with nutrients and is well-known for balancing hormones. It is a plant source of iodine and is rich in vitamins, opening up our body's detox pathways, which helps us get healthier faster and keep us healthy. It also helps prevent iron deficiency, so we feel better.

  • Coleus Forskohlii: This magic bullet helps reduce blood pressure and greatly enhances the immune system, especially respiratory disorders, including asthma. This plant is rich in alkaloids, strongly influencing our body's systems. It's also a superstar regarding weight loss and fat burning.

  • Astragalus Root: Astragalus root is one of the best immune boosters because it's known to increase your body's white blood cell count, our body's first line of defense. It's also known to kill viruses and bacteria, something we all need a lot of now.

LynFit Thyro-Boost can be used in conjunction with your prescription medication. It may make it work the way it should. Thyro-Boost nourishes the thyroid and supplies it with the fuel it needs to work properly, allowing it to do its job vs. doing the work for it, which eventually backfires and worsens things.
