Thyroid Peroxidase (TPO) and Its Role:
- Iodination of Tyrosine Residues:
- TPO catalyzes the iodination of tyrosine residues in thyroglobulin, a large glycoprotein produced and stored in the thyroid gland. This process involves the addition of iodine to specific tyrosine residues within thyroglobulin, forming monoiodotyrosine (MIT) and diiodotyrosine (DIT).
- Coupling Reaction:
- TPO also catalyzes the coupling of iodinated tyrosine residues to form the thyroid hormones. Two molecules of DIT combine to form thyroxine (T4), while one molecule of MIT and one molecule of DIT combine to form triiodothyronine (T3).

Steps Involved in Thyroid Hormone Synthesis:
- Iodide Uptake:
- Iodide ions (I-) are actively transported into the thyroid follicular cells from the bloodstream.
- Oxidation and Iodination:
- TPO oxidizes iodide ions to iodine (I2) and facilitates the attachment of iodine to tyrosine residues in thyroglobulin, forming MIT and DIT.
- Coupling Reaction:
- TPO catalyzes the coupling of iodinated tyrosines (MIT and DIT) to produce T4 and T3 within the thyroglobulin molecule.
- Storage and Release:
- The iodinated thyroglobulin is stored in the thyroid follicles until needed. Upon stimulation by thyroid-stimulating hormone (TSH), thyroglobulin is taken up by the follicular cells, and thyroid hormones (T3 and T4) are released into the bloodstream after proteolytic cleavage.
The enzyme that utilizes selenium to convert thyroxine (T4) to triiodothyronine (T3) is iodothyronine deiodinase. There are three types of iodothyronine deiodinases (D1, D2, and D3), and they all play roles in the activation and deactivation of thyroid hormones:
- Type I Deiodinase (D1):
- Location: Found primarily in the liver, kidneys, and thyroid gland.
- Function: Converts T4 to T3 and reverse T3 (rT3) to diiodothyronine (T2).
- Type II Deiodinase (D2):
- Location: Found in the brain, pituitary gland, brown adipose tissue, and skeletal muscle.
- Function: Converts T4 to T3 locally within tissues, contributing to the regulation of thyroid hormone activity within those specific tissues.
- Type III Deiodinase (D3):
- Location: Found in the placenta, skin, brain, and developing fetus.
- Function: Deactivates T4 to rT3 and T3 to T2, regulating the levels of active thyroid hormones.
Selenium is a critical component of these deiodinase enzymes, as it is incorporated into the enzymes as the amino acid selenocysteine, which is essential for their catalytic activity. Without adequate selenium, the efficiency of T4 to T3 conversion can be impaired, leading to potential thyroid hormone imbalances.

The Science Behind Thyroid Hormones
Your thyroid works by absorbing iodine and combining it with tyrosine to produce hormones. Selenium-powered enzymes convert T4 into the active form, T3, which your body uses to regulate metabolism. Proper levels of zinc, iron, and vitamins like A and B12 are also necessary for the thyroid to function at its best. Without these nutrients, the thyroid may not produce or activate enough hormones, slowing your metabolism and affecting your health.

Steps Involved in Thyroid Hormone Synthesis:
- Iodide Uptake:
- Iodide ions (I-) are actively transported into the thyroid follicular cells from the bloodstream.
- Oxidation and Iodination:
- TPO oxidizes iodide ions to iodine (I2) and facilitates the attachment of iodine to tyrosine residues in thyroglobulin, forming MIT and DIT.
- Coupling Reaction:
- TPO catalyzes the coupling of iodinated tyrosines (MIT and DIT) to produce T4 and T3 within the thyroglobulin molecule.
- Storage and Release:
- The iodinated thyroglobulin is stored in the thyroid follicles until needed. Upon stimulation by thyroid-stimulating hormone (TSH), thyroglobulin is taken up by the follicular cells, and thyroid hormones (T3 and T4) are released into the bloodstream after proteolytic cleavage.
The enzyme that utilizes selenium to convert thyroxine (T4) to triiodothyronine (T3) is iodothyronine deiodinase. There are three types of iodothyronine deiodinases (D1, D2, and D3), and they all play roles in the activation and deactivation of thyroid hormones:
- Type I Deiodinase (D1):
- Location: Found primarily in the liver, kidneys, and thyroid gland.
- Function: Converts T4 to T3 and reverse T3 (rT3) to diiodothyronine (T2).
- Type II Deiodinase (D2):
- Location: Found in the brain, pituitary gland, brown adipose tissue, and skeletal muscle.
- Function: Converts T4 to T3 locally within tissues, contributing to the regulation of thyroid hormone activity within those specific tissues.
- Type III Deiodinase (D3):
- Location: Found in the placenta, skin, brain, and developing fetus.
- Function: Deactivates T4 to rT3 and T3 to T2, regulating the levels of active thyroid hormones.
Selenium is a critical component of these deiodinase enzymes, as it is incorporated into the enzymes as the amino acid selenocysteine, which is essential for their catalytic activity. Without adequate selenium, the efficiency of T4 to T3 conversion can be impaired, leading to potential thyroid hormone imbalances.

Testosterone: The Power Behind Strength and Vitality
Testosterone is the driving force behind muscle growth, energy levels, and overall performance. This key hormone supports everything from building lean muscle to maintaining a healthy libido and feeling mentally sharp. When your testosterone levels are balanced, you feel strong, confident, and ready to take on anything.
When testosterone production is low or out of balance, you might experience fatigue, reduced strength, difficulty building muscle, or even mood changes. Supporting your body with the nutrients it needs to produce testosterone naturally can transform your energy and help you achieve your health and fitness goals.
Why Your Body Chemistry Matters
Understanding your body’s chemistry is essential for optimizing your testosterone levels. Testosterone production relies on specific nutrients that fuel the processes involved in making this vital hormone. Knowing what your body needs allows you to address deficiencies, improve hormone balance, and unlock your full potential for strength and vitality.
With the right nutrients, your body can produce and use testosterone efficiently, enhancing your metabolism, building muscle, and boosting your overall health.
The Nutrients Your Testosterone Needs
Testosterone is your body’s “performance hormone,” helping with muscle growth, energy, and overall vitality. Producing it depends on having the right nutrients and habits.
- Zinc: Found in foods like meat, nuts, and legumes, zinc helps your body make testosterone and convert it into a more powerful form, DHT.

Testosterone isn’t just important for men—it plays a vital role in women’s health too. In men, testosterone is primarily produced in the testes, while in women, it is produced in smaller amounts by the ovaries and adrenal glands. For both, testosterone impacts muscle strength, energy, mood, and overall vitality.
For both men and women, maintaining balanced testosterone levels is crucial for metabolic health, physical performance, and well-being. When supported by the right nutrients and lifestyle habits, your body can produce and utilize testosterone effectively, regardless of gender.
Here’s how it works:
The process begins with cholesterol, the raw material for all steroid hormones, including testosterone. Through a series of enzymatic reactions supported by nutrients like zinc, magnesium, and vitamin K2, cholesterol is converted into pregnenolone, the first step in hormone production. This leads to the synthesis of testosterone, which may then be converted into its more potent form, DHT, or used directly by the body.
- Cholesterol Conversion: Cholesterol acts as the raw material for testosterone. The body starts by breaking down cholesterol into pregnenolone, the first step in steroid hormone synthesis.
- Enzymatic Actions: Zinc, Vitamin K2, and Selenium support various enzyme functions needed to produce testosterone and convert it into DHT when necessary.
- Supportive Nutrients: Magnesium and Omega-3s ensure that testosterone remains in its “free” form, ready for use by your body.
- Hormonal Regulation: Nutrients like Vitamin D and B6 help regulate hormone production and maintain balance.
This intricate process is sensitive to nutrient deficiencies, poor sleep, high stress, and a lack of physical activity. Supporting your body with the right nutrients and lifestyle choices ensures your testosterone production is efficient, helping you feel strong, energized, and focused.

Muscle Growth Pathways
Click each tab to learn more.
mTOR Pathway
Mechanism: The mechanistic target of rapamycin (mTOR) pathway is a central regulator of muscle protein synthesis and hypertrophy. mTOR integrates signals from growth factors, nutrients, and mechanical stress to stimulate protein synthesis.
Activation: This pathway is activated by amino acids (especially leucine), insulin, and mechanical loading (resistance exercise).
Effect: Activation of mTOR leads to increased protein synthesis and muscle cell growth. It promotes the translation of mRNA into proteins, contributing to muscle hypertrophy.
IGF-1 Pathway
Mechanism: Insulin-like growth factor 1 (IGF-1) is a key hormone that mediates the effects of growth hormone (GH). IGF-1 binds to its receptor, activating intracellular signaling cascades that promote muscle growth.
Activation: IGF-1 signaling is activated by growth hormone, exercise, and adequate nutrition.
Effect: IGF-1 signaling stimulates mTOR pathway activation, enhances protein synthesis, and promotes satellite cell proliferation and differentiation, leading to muscle hypertrophy.
AMPK Pathway
Mechanism: AMP-activated protein kinase (AMPK) is a key regulator of cellular energy homeostasis. It is activated in response to low energy levels and regulates metabolism and muscle growth.
Activation: AMPK is activated by exercise, low cellular ATP levels, and increased AMP/ATP ratio.
Effect: AMPK activation can inhibit mTOR signaling and muscle protein synthesis under low-energy conditions. While it primarily promotes energy conservation, its role in muscle hypertrophy is complex and context-dependent.
MAPK Pathway
Mechanism: Mitogen-activated protein kinase (MAPK) pathway includes several sub-pathways (e.g., ERK1/2, p38 MAPK) that are involved in cell growth, differentiation, and response to stress.
Activation: MAPK signaling is activated by various growth factors, cytokines, and mechanical stress.
Effect: MAPK pathways can influence muscle cell proliferation and differentiation. ERK1/2 is associated with muscle cell proliferation, while p38 MAPK is involved in stress responses and muscle cell differentiation.

Building muscle involves a complex network of pathways that regulate how your body repairs and grows muscle fibers.
Here’s how the main pathways work:
- mTOR Pathway: This is the body’s central muscle-building pathway, activated by eating protein (especially leucine) and resistance exercise. It tells your body to synthesize muscle proteins, leading to growth.
- IGF-1 Pathway: IGF-1, a hormone triggered by growth hormone, works with mTOR to stimulate muscle growth and repair by activating satellite cells and promoting protein synthesis.
- AMPK Pathway: AMPK helps regulate energy levels. When energy is low, this pathway focuses on conserving energy rather than building muscle, making it important to stay fueled for growth.
- MAPK Pathway: This pathway responds to stress, like resistance training, by promoting muscle cell growth and repair.
- β-Adrenergic Pathway: Triggered by adrenaline during exercise, this pathway increases muscle protein synthesis and nutrient uptake for growth.
- Wnt/β-Catenin Pathway: This supports muscle regeneration and growth by activating cells involved in muscle repair.
- NF-κB Pathway: While short-term activation helps muscles adapt to stress, chronic inflammation through this pathway can break down muscle, so managing inflammation is key.
Simplified Summary
- Protein and Exercise: Eating enough protein and resistance training are essential for activating pathways like mTOR and IGF-1, which drive muscle repair and growth.
- Energy Balance: Proper fueling ensures pathways like AMPK focus on building muscle rather than conserving energy.
- Stress and Recovery: Exercise-induced stress activates repair mechanisms, but balancing it with recovery helps avoid inflammation that can hinder growth.
By combining effective training, proper nutrition, and recovery strategies, your body efficiently repairs and builds muscle, helping you achieve greater strength and performance.
Muscle growth happens through a combination of stress, recovery, and adaptation. When you perform resistance exercises, your muscles experience small tears in their fibers. The body repairs these tears by activating various pathways that build the muscle back stronger and larger.
Key components of how muscle growth works:
- Mechanical Stress: Resistance training triggers mechanical stress, activating pathways like mTOR and MAPK to repair and grow muscle fibers.
- Nutritional Support: Amino acids from dietary protein provide the building blocks for new muscle, while hormones like IGF-1 enhance the process.
- Energy Regulation: Pathways like AMPK ensure your body has the energy needed to sustain muscle growth while conserving resources when energy is low.
- Inflammation Control: Managing inflammation prevents chronic activation of pathways like NF-κB, which can hinder muscle growth.
By combining effective training, proper nutrition, and recovery strategies, your body efficiently repairs and builds muscle, helping you achieve greater strength and performance.
