What Happens When Your Body Is Severely Vitamin D Deficient?

These 12 bizarre symptoms might shock you.

You May Never Skip Your Vitamin D Again After Reading This:

1/ Your head starts sweating uncontrollably... 🧵 (THREAD) Image
Strange, but true.

This bizarre symptom shows up in infants, teenagers, and adults. Excessive head sweating is a red flag, especially in children.

But why?
First, 25,000 genes exist in your body.

10% are directly controlled by vitamin D. Your blood tests only show inactive vitamin D — not what's happening in your cells...
When Dr. Hollis presented his findings to top vitamin D researchers, he was attacked for his conclusions.

Why? Because effective vitamin D treatment directly competes with the top-selling drugs on the market.

Here are 10 more vitamin D deficiency symptoms you should know:
2/ Your sleep gets destroyed by night sweats.

You wake up with a soaked pillow despite cool temperatures.

Vitamin D deficiency triggers an overactive immune response, disrupting your body's temperature control center:
3/ Your emotions become a rollercoaster.

Vitamin D directly controls your emotional regulation through complex brain pathways.

Adequate vitamin D levels help protect neurons and reduce inflammation, which can otherwise exacerbate mood disorders.
4/ When you're vitamin D deficient, you run the risk of a dysfunctional immune system.

This may cause symptoms like:

• Autoimmune Reactions
• Recurrent Infections
• Chronic Fatigue
• Inflammation

Here's why:
5/ Your motivation vanishes completely.

Tasks pile up. Everything feels overwhelming.

This isn't laziness — it's your brain's motivation center malfunctioning without vitamin D.
6/ Panic attacks strike unexpectedly.

These aren't just anxiety episodes. Your brain's fear center is malfunctioning from a lack of vitamin D, disrupting crucial serotonin pathways.
7/ A deep ache sets into your bones.

Not sharp pain, but a deep internal ache — especially in your:

• Hips
• Pelvis
• Upper legs
• Lower back

This is osteomalacia beginning — your bones literally softening. Here's how it works:
8/ Your muscles start failing you.

Without vitamin D, calcium can't enter your muscle cells properly.

The result? Progressive weakness, especially in the legs and shoulders. Your muscles physically can't contract.
9/ Your joints become stiff.

Stiffness takes over your knees and fingers as vitamin D is crucial for cartilage and collagen.

10/ Fatigue becomes your new normal.

Your cellular energy factories (mitochondria) are dying. Old viruses can reactivate, draining you further. Image
11/ Your brain feels like it's in a fog.

Decision-making becomes impossible. Focus vanishes.

12/ You can't stop eating yet never feel satisfied.

Without vitamin D, nutrients can't properly enter your cells, leaving you constantly craving more.
How much vitamin D do you need?

40 minutes of sun gives you 20,000 IU of vitamin D3.

For different deficiencies, try:

- 10,000-20,000 IU for general deficiency.
- 50,000 IU of vitamin D3 daily for chronic fatigue.

Toxicity occurs when taking 100,000 IU daily for weeks.
Essential cofactors for vitamin D are magnesium, vitamin K2, zinc, and B6.

Without these, you won't get the full benefits. This is why most vitamin D supplements fail.
Effective vitamin D supplementation threatens a multi-billion dollar drug industry.

The medical establishment actively suppresses this information.

But the science is clear: vitamin D deficiency underlies many modern health problems. Image

Chapstick is not helping you like you think it is.

It is actually the reason your lips are always dry....

Here’s why: 🧵 Image
Ever wonder why you always need more lip balm?

It feels good for a minute…
Then your lips get drier, so you reapply.

Again and again.

That’s not an accident. Let me explain…
Most chapsticks contain ingredients like:
• Alcohol
• Solvents
• Mineral oil
• Wax

These don’t moisturize your lips.

They dry them out on purpose.

The oil that beats Advil for inflammation… and why you don’t know about it.

Used for over 3000 years but forgotten by modern medicine.

Here’s what makes it so effective, and why it matters: 🧵 Image
The oil is called black seed oil.

It’s extracted from the seeds of Nigella sativa, a plant used in traditional medicine for centuries.

Its key compound, thymoquinone, targets inflammation and immune dysfunction.

But here’s where it gets wild…
Research shows black seed oil may help with:
• Asthma
• Autoimmune conditions
• Skin inflammation
• Diabetes
• Brain fog
• Even some types of cancer

How does one oil do all that?

It comes down to one thing: inflammation.

This co-op had to throw out $90,000 worth of brand-new dairy…

Not because it was expired, but for a reason you probably wouldn’t believe.

Let’s unpack what really happened: 🧵
A Michigan farm co-op called Nourish Cooperative was forced to destroy raw milk, butter, yogurt, and cheese.

Not because of contamination.
Not because of a single complaint.

The reason? The state said their labeling violated regulations.
They were using a “pet food” license to legally sell raw dairy.

This is a common workaround in states where raw milk sales are restricted.

But in July 2024, Michigan officials stepped in and ordered them to discard $90,000 worth of perfectly good food.

The one vitamin Harvard is scared of…
Because it threatens a trillion-dollar lie.

Here’s what you need to know: 🧵 Image
Vitamin D3 isn’t optional. It’s essential.
Your immune system relies on it to function properly.

Deficiency increases your risk of cancer, autoimmune disease, chronic inflammation, and infections.

So why are we told to fear the sun, the primary source of this critical nutrient?
Vitamin D is made when sunlight hits the cholesterol in your skin.

Yet we’re told cholesterol is bad.
We’re told to avoid the sun.

Meanwhile, Big Pharma’s profits quietly pile up.

And the institutions we trust, like Harvard, rarely speak out in support of vitamin D3.

Why? Image

The one side effect of testosterone therapy that Joe Rogan rarely mentions…

Let's break it down: 🧵 Image
TRT (testosterone replacement therapy) has benefits:

• Boosts energy
• Improves libido
• Builds muscle
• Elevates mood

But it comes with one serious risk... especially for younger men.
Here’s what happens when you take external testosterone:

Your brain detects high levels…

...and stops signaling your body to make more.

This causes your testicles to reduce function, shrink, and in some cases, become permanently suppressed.

This is called testicular atrophy.

The one mineral that over 50% of Americans are deficient in… but that they desperately need.

Here’s what it is and why it matters: 🧵 Image
Over 48% of Americans are deficient in magnesium, and most don’t know it.

NHANES data from the NIH shows nearly half of U.S. adults fall short of the recommended intake.

Standard blood tests often miss it, since over 99% of magnesium is stored inside cells, not in the blood.
Magnesium supports over 300 enzyme reactions and helps with:

• Energy production
• Muscle and nerve function
• Sleep and mood regulation
• DNA and protein synthesis
• Blood sugar and blood pressure control

Deficiency affects sleep, stress, insulin sensitivity, and more.
