Meet the Hormones That Decide How Your Body Feels

Energy. Mood. Sleep. Metabolism. Strength. Fertility. Resilience.

They are governed by a small group of chemical messengers that determine how your cells function every single day. Hormone decide how efficiently you produce energy, how well you handle stress, whether you build or break down tissue, and how clearly your brain operates.

When these hormones are balanced, the body feels steady, strong, and adaptable.
When they’re off, everything feels harder.

Below are the core hormones that shape how your body feels.

Thyroid Hormones

Regulate the rate of cellular respiration—how quickly oxygen and nutrients are turned into usable energy (ATP). T3 affects almost every tissue: it increases mitochondrial activity, stabilizes blood sugar by improving glucose uptake, supports digestion, healthy cholesterol, cell differentiation, and maintains healthy reproductive hormone balance.

To optimize:

• Eat frequent meals (carbs + protein) to keep stress hormones down and support T4→T3 conversion
• Sunlight + adequate vitamin D to improve thyroid receptor sensitivity
• Limit PUFAs (polyunsaturated fats)
• Ensure sufficient salt, copper, magnesium, and B vitamins for hormone production and conversion
• Support liver health, since ~80% of T3 is produced through liver conversion of T4
• Red light therapy
• Supplement with a combination of T3 and T4 (natural desiccated thyroid) as needed

Progesterone

Progesterone is the primary protective hormone. It stabilizes cells by improving mitochondrial efficiency, lowering inflammation, opposing excessive estrogen action, and supporting healthy blood sugar regulation. Progesterone promotes deep sleep, reduces aldosterone (bloating), lowers prolactin, protects the brain from excitotoxicity, and improves oxygen utilization.

To optimize:

• Eat enough calories, especially carbs, to prevent cortisol spikes which lower progesterone
• Ensure sunlight + vitamin D to support ovaries and adrenals
• Optimize thyroid function
• Reduce chronic emotional stress
• Avoid PUFAs, which interfere with progesterone synthesis
• Optimize intake of vitamin C and E
• Get sunlight
• Use bioidentical progesterone (cream or capsules)

Testosterone

Testosterone is the hormone that gives the body its strength, repair capacity, and metabolic drive. It increases the rate at which tissues rebuild, improves how efficiently the body produces energy, and keeps inflammation low. Optimal testosterone supports muscle mass, bone density, oxygen-carrying capacity, libido, and stable, grounded mood. When testosterone is low, the body becomes easier to stress

To optimize:

• Support thyroid function
• Get regular sunlight
• Strength train
• Eat enough protein, cholesterol, and micronutrients like zinc, vitamin A, magnesium, etc.
• Avoid exposure to xenoestrogens and plastics
• Reduce visceral fat which increases aromatase (the enzyme that converts testosterone to estrogen)
• Support liver clearance (adequate protein, calcium, raw carrot/charcoal)

DHEA

DHEA is one of the body’s primary “youth” steroid hormones, produced mainly in the adrenal glands. It acts as both a buffer and a reservoir: buffering the effects of cortisol during stress while supplying the raw materials for downstream hormones.

DHEA keeps cortisol in check. In a healthy endocrine system, DHEA and cortisol rise and fall together. But with chronic stress, low thyroid, inflammation, or aging, cortisol stays high while DHEA falls. This shift is associated with faster aging, weaker metabolic flexibility, immune dysregulation, loss of muscle and bone mass, and greater vulnerability to inflammatory conditions. DHEA naturally declines with age, but it also falls prematurely in states of low thyroid, nutrient deficiency, chronic inflammation, sleep disruption, and persistent stress.

To optimize:

• Ensure adequate intake of cholesterol, copper, vitamin B3, B5, B6, vitamin C, magnesium, zinc, selenium, etc.
• Get adequate sunlight
• Support thyroid function
• Eat frequently to support blood sugar and lower cortisol
• Supplement with DHEA

Cortisol

Cortisol increases blood sugar during acute stress, but chronic elevation has degenerative effects. It breaks down muscle and tissues for glucose, suppresses thyroid conversion, increases blood sugar instability, raises inflammation long-term, and disrupts sex hormone balance. High cortisol increases prolactin, slows digestion, lowers progesterone, and makes tissues more responsive to estrogen.

To optimize:

• Get morning sunlight
• Keep blood sugar balanced (eat every 3-4 hours)
• Drink coffee with meals / enough nutrients
• Ensure adequate intake of sodium, potassium, and magnesium
• Supplement with pregnenolone
• Supplement with progesterone

Prolactin

Prolactin rises with stress, high estrogen, low thyroid function, fasting, poor sleep, and serotonin excess. It lowers libido, interferes with ovulation, shortens or lengthens cycles, increases breast tenderness, and promotes a more inflammatory, estrogen-dominant environment.

A crucial caveat: prolactin is supposed to rise during pregnancy and breastfeeding. In that context, it helps prepare breast tissue, supports milk production, and shifts the body into a protective, energy-conserving state. Outside of pregnancy, however, high prolactin becomes maladaptive because it mimics a “pseudo-pregnant” state: lower metabolic rate, impaired ovulation, and increased stress reliance.

Prolactin often rises when thyroid function is low. Low T3 slows down dopamine production and weakens ovarian progesterone output, which are two of the major brakes on prolactin. Dopamine is prolactin’s natural counterweight. When dopamine drops, through stress, sleep loss, low protein intake, or thyroid suppression, prolactin rises quickly.

To optimize:

• Support thyroid (T3 lowers prolactin more reliably than anything)
• Increase dopamine (sunlight, adequate protein, regular meals, meaningful activities)
• Reduce estrogen dominance
• Ensure adequate vitamin B6 intake
• Avoid fasting and late-night stress
• Improve sleep and circadian rhythm
• Supplement with progesterone

Estrogen

Estradiol is essential for reproduction and short bursts of tissue growth, but chronically elevated levels can drive excessive tissue growth, promote inflammation, increase water retention, and stress responses. It also burdens the liver, which must continually detoxify and clear it. When estrogen is not properly metabolized, it recirculates and accumulates in tissues, increasing cellular stress.

To optimize:

• Reduce PUFAs (they increase estrogen signaling and oxidative stress)
• Lower xenoestrogen exposure (plastics, fragrances, pesticides)
• Support liver clearance (adequate protein, calcium, raw carrot/charcoal)
• Strengthen thyroid function to improve estrogen detox pathways
• Supplement with bioidentical progesterone

Vitamin D

Why vitamin D matters:

• Immune resilience: Vitamin D activates immune cells, helping your body fight infections. This is why flu and respiratory illnesses spike in winter, when vitamin D levels plummet.
• Bone and muscle health: It enables calcium and phosphorus absorption. Without it, up to 90% of dietary calcium is lost or misdirected. Deficiency leads to osteoporosis, fractures, and rickets.
• Blood sugar regulation: Vitamin D plays a key role in insulin sensitivity and secretion, directly impacting Type 2 diabetes risk.
• Cancer and cell regulation: Vitamin D influences cell growth and neuromuscular function, protecting against malignant changes.

Low vitamin D has been linked to:

• Respiratory infections
• Dementia and cognitive decline
• Type 2 diabetes
• High blood pressure and cardiovascular disease
• At least 17 cancers, including breast and prostate
• Stroke, autoimmune disease (especially Hashimoto’s thyroiditis), and increased all-cause mortality

One large 2007 meta-analysis showed vitamin D supplementation lowered risk of death from all causes.

How to safely optimize vitamin D levels:

• Sunlight: The best source. Mid-day, full-body sun exposure for just 15–30 minutes (pale skin) or up to an hour (darker skin) can generate 10,000 IU naturally.
• Food: Fish, pastured egg yolks, grass-fed butter, organ meats, and certain mushrooms provide modest amounts. Pastured foods are far richer than conventional.
• Supplements: Often necessary, especially in winter or for those with risk factors.

Balance Is Possible

Hormonal balance is achieved by lowering chronic stress signals, improving nutrient status, getting sunlight, protecting thyroid function, optimizing progesterone, and reducing inflammatory inputs.

Every hormone listed above interacts with the others. Thyroid affects progesterone. Progesterone buffers cortisol. Cortisol influences prolactin. Estrogen burdens the liver. Vitamin D modifies receptor sensitivity. Nothing operates alone.

The goal isn’t to micromanage hormones, rather it's to create an internal environment where they regulate themselves properly. Your body is designed for balance. Just give it the inputs to make it happen.
