How Vitamin D Helps Heal Skin Rashes: What Dr. Renu Mahtani Says

Do you suffer from recurring rashes or eczema? Learn how vitamin D helps heal skin rashes by restoring immune balance, by Dr. Renu Mahtani.

Why is vitamin D more than just a nutrient?

Vitamin D is more than just a nutrient; it is the silent hero of our immune system. It acts not just as a vitamin but also as a master hormone that regulates more than 200 genes, many of which play a key role in immune system function. It affects both the innate and adaptive immune systems.

How vitamin D strengthens the immune system and controls inflammation

Vitamin D gives the body the strength to fight infection while also ensuring that the immune system does not become overactive. This balance is important in preventing chronic inflammation.

Importantly, scientists have found that vitamin D receptors (VDRs) are present on many cells in the body, including immune cells. This means that vitamin D not only helps prevent disease but also plays a direct role in controlling inflammation.

Vitamin D and Autoimmune Diseases: The Need for Higher Doses

Vitamin D has shown significant effects in autoimmune diseases. In many such cases, cellular receptors in the body do not respond effectively to standard vitamin D doses. This condition is known as vitamin D resistance.

To overcome this resistance, patients often require higher doses than normal to see any immune-modulating effects.

The Power of Nutrient Synergy: Why Cofactors Matter

Vitamin D works best when supported by essential nutrients such as magnesium, selenium, zinc, and vitamins B2 and B12. These cofactors help activate vitamin D and make it function more efficiently within the body.

From Relief to Recovery: Restoring Immune Balance Naturally

When paired with proper nutrient support, vitamin D not only slows disease, but it can also re-energize a tired immune system. In some cases, this leads to significant improvement or even remission of autoimmune symptoms.

This is why vitamin D is now viewed not just as a supplement but as a scientifically supported therapeutic agent for immune-related conditions, particularly skin disorders such as eczema and psoriasis.

How Vitamin D and Minerals May Help Autoimmune Diseases Naturally

• Autoimmune diseases are on the rise these days. They are not just limited to physical pain or disability, but also affect our quality of life due to the side effects of taking medicines frequently.
• Diseases like rheumatoid arthritis (RA), psoriasis, lupus (SLE), and multiple sclerosis (MS) occur when our immune system starts attacking our own body. This results in inflammation, damage, and gradual loss of body organs and joints.
• Many people still think that vitamin D is only needed for bones. But research done in the last 30 years has proved that vitamin D plays a very important role in keeping our immune system balanced
• When vitamin D is active in our body and is accompanied by essential minerals like magnesium, zinc, and selenium, it can control autoimmune reactions to a great extent. It can also reduce the activity of some genes associated with it.
• Unfortunately, most existing treatments only suppress symptoms – they rarely get to the root of the disease. This leaves many patients feeling overwhelmed, exhausted, and isolated.
• If we really want to end this problem, we need to restore the balance of vitamin D and other essential minerals in our bodies. This is the basic idea of ​​naturopathy, an approach that does not simply suppress the disease but treats the body holistically by understanding it from the inside.

Dr. Renu Mahtani’s Vitamin D Therapy and Her Application of the Coimbra Protocol

A renowned physician from India, Dr. Renu Mahtani, is not only a functional medicine expert but also one of the few experts on reversing autoimmune diseases naturally. Her work in the field of high-dose vitamin D therapy is truly commendable. Her focus is not just on the symptoms of the disease but on balancing the body’s cellular health and immune system from within. This thinking led her to an advanced therapy model called the ‘Coimbra Protocol,’ designed by Brazilian neurologist Dr. Cicero Coimbra specifically for autoimmune diseases. Dr. Mahtani is one of the few certified doctors in India to practice this method.

She believes that vitamin D is not a simple supplement but a powerful hormone that affects over 200 genes in the body and deeply regulates the immune system. Her therapy aims to not only correct vitamin D deficiency but also rebalance the immune system through the right dosage of vitamin D while constantly monitoring parathyroid hormone (PTH), ionized calcium, and inflammatory signals in the body. Her protocol has become a ray of hope for people suffering from psoriasis, eczema, or other autoimmune skin diseases.

1. Psoriasis Problem

Psoriasis is not just a skin disease. It is a chronic autoimmune disorder that affects the body and mind. Many patients experience frustrating outbreaks, limited treatment options, and little long-term relief.

This inspired researchers to think beyond traditional treatments and focus their attention on a powerful but often overlooked ally: vitamin D.

Case Series: What Happened?

Six patients with long-standing psoriasis, many of whom were not responding to conventional treatments, were given daily doses of 30,000 to 60,000 IU of vitamin D3 under the supervision of doctors. This treatment lasted for about 2 to 6 months, and when improvement was seen, a light maintenance dose was continued thereafter to prevent recurrence of the disease.

Results included

• Dramatic reduction in PASI score (a measure of the severity of psoriasis)
• Pruritus resolved completely in many cases
• No side effects or signs of toxicity
• Blood calcium levels remained in the normal range
• Vitamin D dose was individually determined based on PTH response

Note:

 Vitamin D is not just a supplement, but if taken correctly, it can be a game-changer for psoriasis. But be careful. It is not safe to take it on your own. It is important to consult and monitor a qualified health professional before taking high doses to avoid serious complications like hypercalcemia. 

Psoriasis: A case series by Dr. Mahtani

Through her clinic and online platform, Dr. Mahtani not only provides information and education but also creates a personalized plan by carefully understanding each patient’s condition. Her therapy is science-based and is completely safe and effective, which is why she has helped thousands of people get rid of chronic skin problems through natural methods.

Why Vitamin D Matters for Skin

Dr. Renu Mahtani believes that vitamin D is not just a common nutrient but a “master hormone,” influencing more than 200 genes in our body. She has used the Coimbra Protocol to show how the right dose of vitamin D can balance our immune system. This therapy offers new hope, especially in autoimmune and inflammatory skin conditions such as eczema and psoriasis.

Vitamin D calms down Th17 cells in the body that drive inflammation while also boosting cells called T-regs that help keep autoimmunity in check. This dual action provides relief from skin irritation, itching, and rashes. Dr. Mahtani prescribes personalized high-dose vitamin D therapy for each patient with this scientific basis in mind to get to the root of the problem rather than suppressing the symptoms.

Her protocol is not only precise but also completely evidence-based and safe, as it takes into account regular checkups and necessary cofactor support. This treatment is like a new light for those who have been suffering from chronic skin diseases for years.

High-Dose Coimbra Protocol Explained

Dr. Renu Mahtani explains that many patients suffering from autoimmune diseases such as eczema, psoriasis, or lupus suffer from vitamin D resistance. This means that the usual dosage of 400 to 800 IU per day is not enough for them, as the body’s cells are unable to use vitamin D properly.

In such cases, Dr. Mahtani prescribes a vitamin D dosage based on each individual’s needs. Sometimes it can be 5,000 to 10,000 IU or even more. This is not a blind guess but a scientific method in which she takes the help of important lab markers, especially parathyroid hormone (PTH). When PTH levels are slightly suppressed but not too low (around 15-30 pg/mL), it is an indication that the body is getting the right amount of vitamin D and the immune system is being safely regulated.

In addition, ionized calcium, vitamin D levels, and kidney function are regularly monitored to ensure the treatment is completely safe. Dr. Mahtani’s goal is not just to improve lab values but to balance the immune system and heal skin problems, such as chronic inflammation, from within naturally and sustainably.

Real-World Evidence for Skin

Several case studies and clinical observations show that taking high doses of vitamin D daily can lead to dramatic improvements in autoimmune skin conditions like psoriasis and eczema. When patients started taking 5,000 to 10,000 IU of vitamin D daily along with essential co-factors like magnesium, vitamin K2, and zinc and made certain dietary changes, they saw a visible difference in rashes, itching, and flaky skin.

Dr. Renu Mahtani highlights this repeatedly in her educational videos and clinical experiences. In her words:

“Psoriasis and eczema respond very well to vitamin D therapy – especially when used through the Coimbra Protocol.”

She further explains that this improvement comes from vitamin D’s power to balance the immune system. Specifically, it reduces Th17 T-cells, which cause inflammation in the body, and boosts Treg (regulatory cells), which help soothe the skin by calming autoimmune reactions.

Safety & Nutrient Support

The biggest misconception about taking high doses of vitamin D is that it can poison the body, but the reality is a little different. Dr. Renu Mahtani explains very clearly that the real problem is not vitamin D but increased calcium levels in the body, medically known as hypercalcemia. Vitamin D increases calcium absorption in the body, and if taken without supervision, it can cause complications. But fear not.

The Coimbra protocol that Dr. Mahtani follows takes precautions at every step, such as regular checkups and proper diet and hydration, to ensure that the entire process is safe. The real focus should not be on restricting vitamin D but on maintaining calcium balance.

Conclusion

If you’ve been silently struggling with persistent rashes, eczema, or psoriasis, it’s time to seek out deeper healing, not just symptom relief. Dr. Renu Mahtani’s evidence-based approach using high-dose vitamin D therapy under the Coimbra Protocol brings new hope to those who have tried everything and still live with chronic discomfort. Her clinical results and patient outcomes show that when used wisely and scientifically, vitamin D is more than just a supplement – it’s a master regulator of immunity and inflammation.
