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

Many people believe that worsening eyesight is simply inevitable.

The truth is that you can naturally GET YOUR EYESIGHT BACK.

Don’t believe me? Check this out: 🧵
By age 45, most people need glasses.

There is a specific problem that often goes undetected in routine eye exams.

It is called contrast sensitivity loss, which is the inability to see subtle differences between shades of gray.
Contrast sensitivity loss causes blurriness, especially in low-light environments.

Standard eye exams use high-contrast charts, which are black letters on white backgrounds.

Because of this, the condition often goes undetected.

What happens if you use rice water on your hair for 2 weeks?

This ancient remedy is rich in nutrients, and modern science is finally catching up.

It can promote growth, reduce frizz, and improve scalp health.

Here’s exactly how to make it… and why it works so well: 🧵 Image
Rice water has been used in Asia for centuries.

But most people today make it the wrong way.

Simply soaking rice in water for a few hours and applying it will not deliver real results.
The key is fermentation.

During fermentation, natural microbes break down the starch in rice water and release bioactive compounds that strengthen the hair and support scalp health.

This process is what transforms plain rice water into an effective remedy.

Millions of people struggle with depression.
In many cases, the root cause is a simple nutrient deficiency.

Here are 5 key deficiencies that can silently trigger depression.

1/ Zinc… 🧵 Image
Zinc is essential for neurotransmitter production and hundreds of biochemical reactions.

Deficiency can be genetic or dietary, especially in vegetarians, vegans, or those who don't eat a lot of animal products.

Sources include red meat, shellfish, and other animal proteins.
2/ Vitamin B12

B12 is essential for producing serotonin, the neurotransmitter that helps regulate mood.

Deficiency can contribute to fatigue, low energy, and symptoms of depression.

Common causes include low stomach acid, absorption difficulties, or inadequate dietary intake.

Baking soda isn’t just for reducing odors in your refrigerator.

Here are 7 unexpected benefits of baking soda you can use in your everyday life: 🧵
1/ Teeth whitener and mouthwash

Baking soda whitens teeth & changes the mouth’s pH to reduce harmful bacteria.

This helps:
• Reduce bad breath
• Limit tartar & plaque buildup
• Clean teeth gently

Mix 1 tablespoon of baking soda with 1 tablespoon of water. Brush & rinse.
2/ Natural deodorant

Sweat itself does not cause odor. Bacteria are responsible for body odor.

Baking soda creates an alkaline environment where odor-causing bacteria cannot survive.

And the best part?
You can make your own natural deodorant at home in minutes…

Not all supplements are safe.
In fact, some can be harmful to your health.

Here are 10 vitamins you should never take… and why: 🧵
1/ Synthetic Vitamin A
(often labeled as retinyl palmitate or retinyl acetate)

Builds up in the liver and fat tissue.
Linked to toxicity, birth defects, and bone loss.
In skin creams, it can become carcinogenic under UV light.

Better sources: egg yolks, liver, cod liver oil.
2/ Synthetic Beta-Carotene

Manufactured from petroleum byproducts.
In studies, smokers taking it had a higher risk of lung cancer.
Natural carotenoids protect health, synthetic versions can damage it.

Best sources: carrots, leafy greens, sweet potatoes.

I’m 60, and it took me over 30 years to figure this out.

These are the 7 biggest health mistakes I made… and why they almost ruined me:

1/ Taking too many vitamins 🧵
At one point, I was taking over 100 supplements a day.
Entire bottles, not just pills.

I kept searching for the vitamin that would restore my energy.
I never found it.

Here’s what I didn’t understand back then…
Supplements don’t work without a solid nutritional foundation.

My diet lacked key macronutrients, especially protein and healthy fats.
No supplement can replace those.

What works instead:
Start the day with protein and get energy from healthy fats, not sugar. Image
