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

How can 20,000 IU of vitamin D3 be toxic if 40 minutes of sun exposure provides the same amount?

Yet, most guidelines recommend only 600 IU daily—just enough to prevent rickets, not optimize health.

Here’s why you need way more vitamin D3 than you think:🧵 Image
Over 90% of people are vitamin D deficient—and don’t know it.

Why it matters:
• It controls 10% of your genes
• It’s vital for immunity, blood pressure, muscles, and brain health
• Low levels are linked to depression, pain, and inflammation

Why aren’t people getting enough? Image
Modern life makes getting enough vitamin D nearly impossible.

More time indoors means less sun exposure. Glass blocks UV rays so sunlight through windows won’t help. If your shadow is longer than you, your body isn’t absorbing vitamin D.

Most people remain deficient year-round.

Egg prices are NOT an accident.

Bird flu is back in the headlines—but what’s really happening?

They’re using the COVID playbook again. Only this time, it’s not about lockdowns.

It’s about controlling your food supply.

Let me explain.👇🧵 Image
Bird flu (H5N1) is a virus that affects birds. Sometimes, it spreads to mammals.

But here’s the key part:

It has been genetically modified in labs for years.

In 2022, a lab-modified strain leaked. Now, they’re using it as an excuse to seize control of food production.
How are they implementing this?

Same COVID tactics:
• Inflated case counts via PCR testing
• Mass culling of healthy poultry
• Rapid vaccine rollouts

This isn’t about stopping disease—it’s about control.

And the consequences? They’re already unfolding…

The keto diet is under attack—why?

Because it can reverse type 2 diabetes in just 10 weeks, eliminating the need for medication.

Dr. Nina Teicholz exposes the shocking truth about dietary guidelines—and what actually works.

Here’s what Big Pharma won’t tell you: 🧵 Image
Millions suffer from “incurable” diseases.

Type 2 diabetes, high blood pressure, and fatty liver are labeled chronic and progressive.

Doctors say you’ll need meds for life, but chronic disease isn’t a life sentence.

New research shows it can be reversed in just 10 weeks—how? Image
The real cause of metabolic disease is ignored.

Most doctors blame genetics, aging, or obesity.

But the true culprit? High-carb diets that spike insulin.

Even “healthy” whole grains turn into sugar in your bloodstream.

The most powerful solution? A ketogenic or low-carb diet.

You’re eating the WRONG foods—without even knowing it.

Most people think these foods are healthy, but they secretly spike blood sugar, cause inflammation, and force the body to store fat.

If you want to lose belly fat, STOP eating these 6 foods immediately.👇🧵 Image
1/ Low-Fat Yogurt

Think it’s healthy? Think again.

Low-fat yogurt is packed with hidden sugars and industrial starch that:
• Spike insulin & increase cravings
• Block fat-burning
• Keep you in fat-storage mode

But yogurt isn’t the only sneaky culprit… there are more.
2/ Processed Meat

Hot dogs, deli meats, and nuggets aren’t just meat—they’re loaded with sugar, starch, and chemicals.

These ingredients trick your body into storing more fat and worsening insulin resistance over time.

But it’s not just meat—protein bars are just as bad… Image

It’s THE microbe that changes EVERYTHING:
L. reuteri.

It revolutionizes health by increasing muscle mass, smoothing wrinkles, and boosting your “love hormone.”

Yet, 96% of people lack it.

Here’s why YOU need it: 🧵 Image
Your gut microbiome is like a fingerprint—unique and complex.

Among hundreds of gut microbes, one stands out: Lactobacillus reuteri.

Studied for over 60 years, this probiotic species has extraordinary powers.

But what makes it so special? Image
Back in 1962, Gerhard Reuter isolated L. reuteri from breast milk.

But for 4 decades, scientists underestimated its power—initial studies were centered around its benefits to babies.

However, recent findings revealed something groundbreaking:

This was DESTROYING my life!

I’d wake up at 2 AM and stare at the ceiling for hours. Other nights, I couldn’t sleep at all.

I tried everything—even prescription meds. Nothing worked. Some even made it worse.

Here’s why people struggle with sleep—and how to fix it.🧵 Image
Cortisol is your stress hormone.

At 2 AM, it should be at its lowest. By 8 AM, it should peak to wake you up.

But if you’re wide awake at 2 AM and exhausted at 8 AM, your cortisol rhythm is upside down.

Why? Let’s break it down… Image
Magnesium controls cortisol.

Low magnesium = high cortisol = sleepless nights.

Signs that you’re low in magnesium:
• Tight muscles in your shoulders or back
• Toe cramps when you stretch
• Eye twitches or muscle spasms

The solution? Take magnesium glycinate before bed.
