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

Over two billion people have a zinc deficiency.

There is no functional storage for zinc in the body, so once you stop getting it from your diet, your levels can drop quickly.

Here are seven powerful reasons you should start getting more zinc:

1/ Zinc supports testosterone 🧵
The highest concentration of zinc in the body is found in the prostate gland.

It is vital for sperm production and testosterone balance.

Deficiency can cause low testosterone, low libido, and testicular shrinkage (hypogonadism).
2/ Zinc supports insulin function

The pancreas, especially the beta cells, holds the second-highest concentration of zinc.

Zinc helps insulin work properly & signal to liver.

Low zinc weakens insulin, increasing the risk of insulin resistance, fatty liver, & type 2 diabetes.

“Sugar is bad for you.”

Everyone says it.
But almost no one explains why.

Here’s the truth about what sugar really does to your body: 🧵
Most people know sugar causes:
• Weight gain
• Cavities
• Fatty liver
• High blood pressure
• Weakened immunity

But the real damage goes much deeper…

Sugar wrecks your mitochondria, the tiny power plants inside your cells that keep you alive.
Nearly every modern disease traces back to mitochondrial dysfunction.

Mitochondria are the power plants of your cells, turning fuel into usable energy.

When they become damaged, energy production collapses and chronic disease sets in.

Your liver talks to you.
But not in words… it shows up on your skin.

Here are 9 surprising skin signs your liver might be in trouble:

1/ Chicken skin
Those tiny red bumps on hair follicles are linked to low vitamin A and sometimes vitamin E.

Both vitamins are stored in the liver, and a deficiency can create that rough, bumpy texture.
2/ Yellow skin

This is jaundice, a classic sign of liver dysfunction.

If your skin appears slightly orange, it could also come from too much carrot juice (beta-carotene buildup), not necessarily liver damage.

Not all food is real food.

Many everyday staples are engineered with chemicals and fillers.

Here are 5 of the worst ultra-processed factory foods, and why they’re damaging your health:

1/ Mayonnaise
Most commercial mayo is made with refined seed oils instead of whole ingredients.

These heavily processed oils oxidize easily and are often combined with added sugar, preservatives, and emulsifiers.

The result is a highly inflammatory product with little nutritional value.
2/ Snickers bars

Snickers are primarily made of sugar, corn syrup, refined carbohydrates, vegetable oils, and artificial flavorings.

They cause rapid blood sugar and insulin spikes followed by energy crashes, which can contribute to insulin resistance and weight gain over time.

Most cancer doesn’t just “run in your family.”

It is often triggered by daily choices that take you minimal effort to change.

Here are 7 powerful things you can do right now to lower your risk: 🧵
The conventional model of cancer says it starts with random DNA mutations.

But decades of research tell a different story:

Most cancers begin with damaged mitochondria, the tiny energy factories in your cells.
When mitochondria are damaged, cells switch to a backup energy system: fermentation of sugar.

This fuels abnormal growth and makes cancer cells sugar-hungry.

That is why PET scans look for high glucose activity. Cancer lights up because it thrives on sugar.

Big Pharma doesn't want you to know this...

Magnesium deficiencies are causing anxiety, fatigue, and numerous issues in millions of Americans.

Here’s how magnesium affects your body and how to consume it (according to science): Image
Magnesium is a cofactor for 350 different enzymes in your body.

But only 1% is in your blood. The rest is inside your cells.

This makes it almost impossible to test unless you do a specialized biopsy.
The #1 sign you are magnesium deficient?

FATIGUE.

Why? Because magnesium:

• Powers your mitochondria
• Powers your nervous system
• Creates ATP (your energy currency)
• Runs every cell's sodium-potassium pump
