One of our customers created a video on Tik Tok, featuring our Vitamin D3 & B12 and she- gasp- mentioned that she uses our Vitamin D3 & B12 supplement when she has an eczema flare up (thank you @jasvwong). Which spiralled us into full research mode. In this blog we will be breaking down the potential benefits, tips and tricks if you are looking for the best natural eczema skin treatments. In other words, we read over 2 hours of articles, so that you don’t have to! 

How Vitamin D3 & B12 Can Help with Eczema Flare-Ups

Eczema, also known as atopic dermatitis, is a chronic skin condition that causes dryness, redness, itching, and inflammation. While external treatments like moisturizers and topical steroids can help manage symptoms, addressing the root causes—including nutrient deficiencies—can make a significant difference in long-term skin health.

Two essential vitamins that may help with eczema relief are Vitamin D3 and Vitamin B12. Below we are going to break down their individual benefits and how they can contribute to healthier skin.  

The Role of Vitamin D3 in Eczema Management

Vitamin D3 (cholecalciferol) is a fat-soluble vitamin that plays a crucial role in immune function, skin barrier health, and inflammation reduction. From the studies that we read,  some researchers suggested that individuals with eczema tend to have lower levels of Vitamin D, which can contribute to more frequent and severe flare-ups. This raises an important question to our team: Does Vitamin D help with eczema? Research indicates that maintaining optimal Vitamin D3 levels may support eczema relief by improving skin function and reducing inflammation.

How Vitamin D3 Helps:

Boosts Immune Function – Eczema is often linked to an overactive immune response. Vitamin D3 helps regulate the immune system, reducing the severity of inflammation and allergic reactions.

Strengthens the Skin Barrier – A weakened skin barrier allows allergens and irritants to penetrate more easily, triggering flare-ups. Vitamin D3 enhances the production of ceramides and antimicrobial peptides, which are essential for maintaining a healthy skin barrier.

Reduces Itchiness & Redness – Since Vitamin D3 has anti-inflammatory properties, it can help calm the skin, reducing redness and irritation associated with eczema.

Supports Skin Healing – Eczema-prone skin often struggles with slow healing and increased susceptibility to infections. Vitamin D3 aids in the regeneration of skin cells and speeds up the healing process.

Best Sources of Vitamin D3:

• Sunlight: Your body produces Vitamin D when exposed to the sun, but during colder months or for those with darker skin, supplementation may be necessary.

• Food sources: Fatty fish (salmon, mackerel), egg yolks, and fortified dairy products.

• Supplements: A high-quality Vitamin D3 supplement for eczema relief can help maintain optimal levels, especially if you have limited sun exposure.

The Role of Vitamin B12 in Eczema Relief

Vitamin B12 (cobalamin) is a water-soluble vitamin that plays a key role in skin cell regeneration, inflammation control, and nerve function. Some research suggests that a deficiency in B12 may contribute to worsening eczema symptoms.

How Vitamin B12 Helps:

Reduces Skin Inflammation – Vitamin B12 has been shown to have anti-inflammatory properties, making it beneficial for soothing eczema-prone skin.

Promotes Skin Barrier Repair – It helps maintain the skin’s moisture levels and prevents excessive dryness, which is a common eczema trigger.

Supports Nerve Health – Eczema can cause intense itching, sometimes leading to scratching that worsens skin damage. B12 supports nerve function, which may help reduce the dreaded iching.

Topical Benefits – Some studies suggest that topical Vitamin B12 creams can be effective in reducing eczema symptoms, particularly in children and those with mild to moderate eczema.

Best Sources of Vitamin B12:

• Animal-based foods: Meat, fish, eggs, and dairy products.

• Fortified foods: Certain plant-based milks and cereals for those following a vegetarian or vegan diet.

• Supplements: A Vitamin B12 supplement for skin health can be especially beneficial for those with dietary restrictions or absorption issues.

Best Vitamins for Eczema & How to Heal Eczema Naturally

If you suspect a deficiency, consider getting a blood test to check your Vitamin D and B12 levels. If they’re low, adding supplements, nutrient-rich foods, and potentially topical applications can help support your skin health. We recommend our Vegan Vitamin D3 & B12 -  it’s a treat that’s good for you and so delicious that you actually look forward to taking your vitamins. . 

💡 Pro tip: Since Vitamin D3 is fat-soluble, it’s best absorbed when taken with a meal containing healthy fats (avocado, nuts, or olive oil). B12 is best taken consistently and may require supplementation, especially for vegetarians and vegans.

In addition to Vitamin D3 and B12 benefits for skin, other natural eczema treatments include consuming anti-inflammatory foods, using fragrance-free moisturizers, and managing stress levels.

Final Thoughts

While eczema is a complex condition with multiple triggers, maintaining optimal Vitamin D3 and B12 levels can be a simple yet powerful way to support skin health. As a disclaimer please note that you should always consult a healthcare professional before starting any new supplement regimen, and pair these nutrients with a holistic skincare routine for the best results.
