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

This one drink before bed can reduce inflammation, balance blood sugar, and support your liver.

It’s not tea. It’s not lemon water.

It’s clove water... and here’s why it works: 🧵
Cloves were once worth more than gold.

Used in China for over 2,000 years as medicine.
During the Black Plague, they were burned in masks and rooms to purify the air for their aromatic, antimicrobial vapors.
Before anesthesia, dentists used clove oil to ease tooth pain.
What gives cloves their remarkable power?

A single compound called eugenol.

Eugenol is:
• Antibacterial
• Antifungal
• Antiviral
• Anti-candida

Its benefits extend far beyond adding flavor to food.

The most dangerous food for your heart…

Isn’t sugar.

It’s something far more common... and it’s probably in your pantry right now.

Here’s what it is and why it’s worse than you’ve been told: 🧵
Sugar is harmful to your heart.

But there is a food that does even more damage.

Some believe it must be omega-6 oils like soy or corn oil. These are harmful.

Yet there is a form of these oils that is far more destructive.

They are called trans fats.
You may think trans fats were banned years ago.

But they never completely disappeared from our food supply. In fact, food manufacturers still use them in ways that are hard to detect.

And the health risks are severe.

You don’t need a fancy detox kit to cleanse your liver.

Just 3 natural ingredients, and 3 minutes in your kitchen.

Here’s how to make it and why it works: 🧵
Your liver is your body’s main detox organ.
It filters toxins, processes hormones, and manages fat storage.

But it is also under constant stress from sugar, alcohol, medications, and chemicals.

That is why these 3 natural ingredients are so effective for supporting your liver.
1/ Apple cider vinegar (ACV)

Its key benefit comes from acetic acid, not from vitamins or minerals.

It helps by:
• Improving insulin sensitivity
• Reducing fat storage
• Supporting fatty liver recovery
• Stabilizing blood sugar

Ever wonder why the French eat bread and pasta so often…

But don’t struggle with obesity like we do in the U.S.?

It’s not better genetics.
It’s not portion sizes.

Here’s what they’re doing differently... and why it matters: 🧵
Let’s be clear: not everyone in France is thin.

But, obesity rates are far lower than in the United States.

Why?

The difference comes down to diet. What they choose to eat, and what they avoid.
The French eat more fat than Americans.

• 4x more butter
• 60% more cheese
• 3x more pork

On average: 180 g of animal fat daily vs. just 72 g in the U.S.

Meanwhile, Americans eat far more vegetable oils like corn, soy, and canola, which promote insulin resistance.

If 20,000 IU of vitamin D3 is “toxic”…
Why does your body produce that much in just 40 minutes of the sun?

Maybe high doses are not dangerous.
Maybe they are essential.

Here’s what happens when you get enough, and why most people don’t: 🧵
Every cell and tissue in your body has receptors for vitamin D.

Yet there is still no medical agreement on what a deficiency actually is.

This lack of clarity is concerning because vitamin D deficiency is incredibly common.
When you are low in vitamin D, the effects can be silent at first.

Over time, it can contribute to:
• Weak immunity
• Autoimmune disorders
• Chronic inflammation
• Depression
• High blood pressure

But here is the shocking part…

You probably already have parasites living inside you.

And most people have no idea.

Here are 7 warning signs your body may be fighting off harmful parasites… and what to do about it: 🧵
1/ Persistent fatigue

If you wake up tired, struggle with energy throughout the day, and cannot explain it, parasites could be one reason.

Some parasites reduce nutrient absorption, while others trigger ongoing immune activity. Both can leave you feeling depleted.
2/ Unexplained rashes

Some parasites can trigger skin reactions.

When parasites enter the bloodstream or tissues, your immune system may release histamines and inflammatory chemicals.

This can result in itching, redness, or irritation, even without a history of skin problems. Image
