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

We’ve used Tylenol for 14 years. It has to be safe… right?

RFK Jr.’s new announcement is making Big Pharma panic… and sparking a nationwide conversation about Tylenol, vaccines, and autism.

Here’s what’s going on: 🧵 Image
Mainstream media is attacking RFK Jr.

They label him “anti-science” and accuse him of spreading “debunked myths.”

But what he is really doing is asking hard questions that Big Pharma does not want answered. Questions about vaccines, Tylenol, and the autism epidemic.
Decades ago, autism affected 1 in 100,000 children.
Today it’s 1 in 31.

The usual excuse is “we’re just better at diagnosing it now.”

But if that were true, we’d find lots of undiagnosed autistic adults in older generations. We don’t.

The rise is real. Something has changed.

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.

Many people struggle with losing muscle as they age.

It is not just about looks. Muscle loss affects metabolism, energy, and overall vitality.

The good news? You can preserve it.

Here are 6 science-backed strategies to help preserve muscle as you get older: 🧵
As we age, both men and women naturally lose muscle in a process called sarcopenia, which means “poverty of the flesh.”

We lose 1 to 2 percent of our muscle each year, which significantly impacts metabolism and mitochondrial function, the energy factories in our muscles.
For women, menopause accelerates muscle loss due to drops in estrogen and progesterone.

Estrogen helps repair and regenerate muscle, supports connective tissue, and maintains collagen.

Progesterone contributes to nerve protection and overall muscle health.

VITAMIN D IS DANGEROUS.

At least, that’s what they want you to think.

Here’s the truth about vitamin D… and why you may need more, not less: 🧵
First, let’s clear up a common misconception.

Vitamin D “dangers” are not the same as vitamin D toxicity.

Most people confuse the two, but they’re very different.
Vitamin D toxicity is extremely rare.

The primary symptom is excess calcium in the blood.

And it would take hundreds of thousands of IU daily, for months, to reach that point.

You can’t stop aging…

But you can slow it down... and in some cases, even reverse the damage.

Here are the 7 most effective strategies to reverse aging from the inside out: 🧵
Most people try to fight aging with creams, serums, or Botox.

The truth is that aging starts inside the body.

Loss of collagen, stiff connective tissue & changes to the fascia are what drive wrinkles and poor posture.

By age 40, we have already lost up to 25% of our collagen.
These factors speed up collagen loss and make us age before our time:

• Excess sugar and refined starch
• Smoking
• Excess UV radiation
• Certain antibiotics

But the good news is collagen can also be rebuilt.

Here are 7 of the most effective ways to protect and restore it.

The word “organic” doesn’t always mean healthier.

Sometimes it’s just marketing.

Here are 13 foods where organic doesn’t matter…
And 13 where it does: 🧵
1/ Sea salt
It’s a mineral, not a crop. No pests, no sprays. “Organic sea salt” is just marketing.

2/ Wild-caught salmon
Wild fish eat whatever is in the ocean. “Organic” means nothing here.

3/ Avocados
Thick skin blocks chemicals. Paying extra for organic isn’t needed.
4/ Baking soda
Mined from the earth. No pesticides involved. “Organic” adds nothing.

5/ Water
Water can’t be sprayed with chemicals. “Organic water” makes no sense.

6/ Walnuts
Hard shells protect the nut. Conventional is just as safe.
