Your thyroid controls your entire life.

If it isn't working, it damages your health, energy, and metabolism.

But 2 out of 3 people with thyroid issues are not aware.

Here are the signs your thyroid isn't working (and how to fix it):

What is your thyroid?

It’s a small butterfly-shaped gland in your neck.

But it’s the master switch of your metabolism.

It runs your:
• Body temp
• Weight
• Energy
• Digestion
• Mood
• Fertility

If it's off, everything else suffers

How it works:

Your brain sends a signal: TSH (thyroid-stimulating hormone)

Your thyroid makes two hormones:
• T4 (inactive)
• T3 (the one that actually gives you energy)

T4 gets converted into T3 in your liver & gut.

If that conversion fails, you feel like hell.

The 3 hidden problems behind thyroid dysfunction:

Problem #1: Poor Conversion (T4 → T3)
• Caused by stress, liver issues, or low nutrients
• You have hormones, but your body can’t use them

If you're struggling with quality sleep, here's one of the best science-backed natural supplements I've found.

Problem #2: Chronic Stress
• High cortisol blocks thyroid function
• You stay tired no matter how much you sleep

Problem #3: Autoimmunity (Hashimoto’s)
• Your immune system attacks your thyroid
• Most common cause, but often missed

Fix #1: Support your T3 conversion

• Eat enough carbs (yes, really)
• Selenium (brazil nuts, eggs, sardines)
• Zinc (beef, pumpkin seeds)
• Magnesium (glycinate or malate)
• Liver support (bitter greens, milk thistle)

Fix #2: Lower cortisol to protect your thyroid

Cortisol blocks T3.

Lower it by:
• Deep sleep (7.5+ hrs)
• Morning sunlight
• Walking after meals
• Meditation or breathwork
• Avoiding overtraining (chronic HIIT = thyroid death)

If you're struggling with quality sleep, here's one of the best science-backed natural supplements I've found.

Fix #3: Heal your gut

Up to 20% of T4 → T3 conversion happens in your gut.

• Fix bloating, constipation
• Cut seed oils & alcohol
• Add probiotics (kefir, yogurt, sauerkraut)
• Test for infections (H. pylori, SIBO, candida)

Fix #4: Remove hidden thyroid killers

• Fluoride in water → blocks iodine
• BPA/plastics → mimic estrogen
• Mold toxins → suppress TSH
• Gluten → linked to Hashimoto’s

Drink filtered water, avoid plastic, and test for mold if symptoms persist.

If you want one master fix:

Heal your metabolism.

Your metabolism depends on:
• Proper nutrition
• Hormone balance
• Deep sleep
• Low stress
• Mitochondrial health
• Blood sugar stability

Thyroid problems are often a signal, not the root.

Harvard scientists just cracked the science to regrow hair.

By 35, 2 in 3 men experience hair loss (regardless of genetics).

Here are 7 ways to prevent hair loss and even regrow your hair:

1. Your follicles are not dead when you lose hair.

Harvard’s 2021 study proved this.

They found that balding scalps still have hair follicle stem cells.

They don’t disappear.
They go inactive.

Hair grows when stimulated, nourished, and oxygenated.

2. Scalp massage (5–10 min/day)

Gentle daily massage increases blood flow, delivers oxygen, and removes tension from the scalp.

A 2016 study showed that massage led to thicker hair after 24 weeks.

Add nourishing oil (rosemary, pumpkin seed, or peppermint) for extra benefit.

Most people feel like sh*t by 40.

But it’s not aging — it’s your body screaming for help.

If you’ve gained belly fat, low energy, and recover slowly...

Here are 4 dotor approved ways to fix age issues & extend your lifespan: 👇

1. Grip strength

Sarcopenia (which is a fancy way of saying age-related muscle loss) raises mortality risk.

Grip strength and muscle loss are proven to be associated with shorter lifespan.

Muscle is a reservoir for glucose, a shield against frailty, and one of the strongest predictors of survival.

Fix: Train to preserve muscle (not build muscle)

Strength train 2–4×/week (full body is best)
Eat 1.2–1.6 g protein/kg daily
Sleep 7-9 hours a day

Muscle isn’t just for athletes or aesthetics; it's actually not optional to extend your lifespan.

Nitric Oxide is the key to longevity.

Dr. Nathan's 19-year research proved it speeds recovery, slows aging, and softens your arteries.

But your body stops producing it as you age (50% of it by 40)

Here's what it is, how to get enough, and why discovering it won a Nobel prize:

Nitric oxide (NO) is a gas your body makes to signal blood vessels to open.

It powers blood flow, oxygen delivery, and cellular repair.

But you start losing it at 30, and by 70, your NO is down 75%.

Losing the ability to repair leads directly to aging and chronic diseases.

Dr. Nathan Bryan calls Nitric Oxide “The Molecule of Life.”

- NO mobilizes stem cells (repair system)
- Activates telomerase (longevity enzyme)
- Enhances mitochondria (your energy factory)

It’s the only molecule that supports all 3 pillars of longevity:

Heart attacks can be prevented.

Dr. Aseem Malhotra proved heart attacks are caused by your habits, food, and the lies you’ve been told.

Here’s the lies he debunked (& fixes to protect your heart):

Lie: High cholesterol is the cause

Heart disease is widely misunderstood.

It’s not just about aging or high cholesterol.

It’s plaque silently building inside your arteries like a pimple beneath the surface.

When it bursts, blood flow is blocked and a heart attack strikes.

Heart disease is the #1 killer on the planet.

• In the UK, 1 in 8 men and 1 in 14 women die from it
• In the US, nearly 50% of adults have it

It kills more people than all cancers combined.

They created a disease overnight to sell you pills.

In 2017, medical authorities lowered "normal" blood pressure from 140/90 to 130/80.

Suddenly, 31 million healthy Americans became "sick."

Here’s the real cause of this symptom, and easy ways to fix it:

1. Resistant Hypertension

Some people don’t respond to standard treatment for high blood pressure.

Their numbers stay high no matter what.

This is resistant hypertension.

And it leaves arteries vulnerable despite “being on meds.”

2. Arteries strain

You don’t feel it happening.

Your heart pumps harder, but each pump causes more damage.

Every beat slams against your artery walls, and over time, they stiffen, scar, and narrow.

But one day it shows up as a heart attack, stroke, or kidney failure.

Grey hair is not aging.

1 in 4 people are turning grey before 30.

Here are 6 science-backed foods for thick & dark hair:

1. Eggs (with yolk)

Nature’s multivitamin for your hair.

Biotin, zinc, sulfur, and protein in one.

Biotin builds keratin, and sulfur boosts shine and hair structure.

2/ Liver (beef or chicken)

Nature’s most concentrated source of hair nutrients:

B12, folate, iron, copper, and biotin.

Supports red blood cell flow, melanocyte health, and keratin production.
