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

7 foods you should never eat again!

You’ve been lied to.

These 7 foods are marketed as healthy—but they’re actually destroying your body.

#7 was tested on rats… and they died.

Let’s expose the truth behind these so-called “healthy” foods:

🧵👇 Image
1/ Granola Bars

“Whole grains + honey” sounds healthy.

But they’re packed with GMO ingredients, glyphosate (a weed killer linked to cancer), and hidden sugars.

One producer (General Mills) even dropped the “100% natural” label from their granola bars after being sued.
2/ Agave Syrup

Marketed as a “healthy sweetener,” some even call it “diabetic-friendly.”

But it’s 85% fructose—making it worse than high-fructose corn syrup.

Your liver processes it like alcohol, leading to insulin resistance, obesity, and liver disease.

Do you know your feet can reveal hidden health problems before they become serious?

Most people ignore these signs—until it’s too late.

Here’s how your feet can reveal early health issues and what to do about them: 🧵👇 Image
Your feet are the farthest from your heart, meaning they receive the least oxygen and nutrients.

Because of this, circulation problems, nerve damage, and other health issues often appear in the feet first—long before symptoms show up elsewhere.

Let’s break it down:👇
Do you feel numbness, tingling, or burning in your feet?

It could be peripheral neuropathy—a sign of nerve damage.

The common cause? A deficiency in vitamin B1 (thiamine).

To fix this, take benfotiamine, a fat-soluble form of B1 that penetrates the nerves more effectively.

Your heart won’t beat without electrolytes!

Your brain? It shuts down.
Your muscles? They collapse.

Electrolyte imbalances can cause palpitations, weakness, and even death—yet most people ignore them.

What exactly are electrolytes? And how can we keep them balanced?🧵👇 Image
Electrolytes are charged minerals that power key bodily functions like:

• Sodium — Hydration & nerves
• Potassium — Heart & muscles
• Calcium — Bones & strength
• Magnesium — Nerves & enzymes

Even a slight imbalance can cause issues.
What are the signs of low electrolytes?

1/ Palpitations — Heart struggles to keep rhythm
2/ Fatigue & muscle weakness — Poor nerve function
3/ Fluid retention — Sodium-potassium imbalance
4/ Dizziness & confusion

These aren’t minor symptoms—severe cases can be life-threatening.

Your body is begging for vitamin D—but you could be missing the signs!

Most people think vitamin D is just for bones. They’re dead wrong.

A severe deficiency can wreck your mood, muscles, and immune system—often in ways you’d never expect.

Let’s break it down:🧵 Image
When Dr. Hollis presented his findings to top vitamin D researchers, he was attacked for his conclusions.

Here are some of the symptoms of vitamin D deficiency:

1/ Uncontrollable head sweating

This isn’t just a random quirk—it’s a major red flag.
2/ Your sleep turns into a nightmare (literally).

Waking up drenched in sweat? Tossing and turning all night?

Vitamin D deficiency disrupts your body’s thermostat, causing excessive sweating at night.

Your immune system overreacts, making sleep harder.

Struggling with swollen legs, ankles, or feet?

It’s not just about salt or poor circulation—the real cause is often overlooked.

Here’s what’s really happening—and 3 simple ways to fix it fast.🧵 Image
The true cause of swollen legs = edema.

Doctors may blame the kidneys, heart, liver, or too much salt.

But the real cause is something else.

It is sugar, interfering and causing a failure in the cellular pumps. Image
Your body has millions of tiny pumps that move fluid in and out of cells.

When they fail, fluid leaks out and builds up in your lower body.

Result? Swollen ankles, feet, and legs.

Are depression and anxiety caused by a missing microbe in your gut?

A new study reveals the gut microbiome’s powerful influence on mood. A groundbreaking probiotic solution could change everything.

Check this out: 🧵👇 Image
The human body produces 17 digestive enzymes. But your microbiome? Over 60.

These microbes help break down fiber into key compounds like acetic acid and butyric acid, which nourish your colon cells and even mimic ketones.
The influence of the gut microbiome extends beyond digestion.

It plays a direct role in producing neurotransmitters such as:

• Serotonin
• Dopamine
• GABA Image
