Living in Portugal is a dream come true for many, but it does come with its unique challenges. One such challenge is the pesky issue of mold. Whether you’re renting or buying, it’s crucial to know how to deal with mold to maintain a healthy living environment.

Why Mold is a Common Issue in Portugal

Portugal’s climate, especially in coastal regions like Porto, Lisbon, and the Algarve, can be quite humid. This humidity often leads to mold growth, particularly in older buildings with poor ventilation. Understanding the regions and conditions prone to mold can help you better prepare and manage this issue.

What to Look Out For When Renting or Buying

When you’re inspecting a property, look for signs of mold in damp areas such as bathrooms, kitchens, and basements. Check for musty odors, discoloration on walls and ceilings, and any visible mold spots. Always ask about the property’s ventilation and heating systems, as these can significantly impact mold growth.

Mold-Prone Regions

  • Coastal Areas: Cities like Lisbon, Porto, and towns along the Algarve coast are more susceptible to mold due to higher humidity levels.
  • Northern Portugal: Regions like Braga and Viana do Castelo experience significant rainfall, contributing to mold issues.
  • Older Buildings: Regardless of the location, older properties often have poorer insulation and ventilation, increasing the likelihood of mold.

How to Remove Mold from Your Home

  • Natural Remedies: Vinegar and baking soda are effective for small mold patches. Simply spray vinegar on the mold, let it sit, and scrub it off.
  • Commercial Products: For larger infestations, consider using commercial mold removers like HG Mould Spray (US), Nanoprotect Mold Ex Pro (PT), or Cillit Bang Black Mould Remover (PT).
  • Professional Help: If the mold problem is extensive, hiring a professional mold removal service can ensure thorough cleaning and prevention. Companies like MoldPro offer comprehensive services.

Dealing with Mold on Clothes and Furniture

  • Clothes: Wash affected clothes with a cup of white vinegar added to the washing machine to kill mold spores. Dry them in direct sunlight if possible.
  • Furniture: For upholstered furniture, use a mixture of mild detergent and water to scrub the mold. Leather items can be cleaned with a mixture of water and rubbing alcohol.

Supporting Your Health if You Get Mold Poisoning

Symptoms and Medical Attention: Mold exposure can lead to respiratory issues, headaches, skin irritation, and fatigue. If you experience any of these symptoms, consult a healthcare provider immediately for a proper diagnosis and treatment plan.

Air Purifiers: Invest in air purifiers with HEPA filters to reduce mold spores in your home. Reliable options include:

  • Dyson
  • Philips

Diet and Supplements: A diet rich in antioxidants and anti-inflammatory foods can support your immune system and help detoxify mold toxins. Along with helpful foods, consider incorporating supplements to aid your body in fighting mold toxicity.

Key foods to include:

  • Garlic: Known for its antifungal properties.
  • Leafy Greens: Such as kale and spinach, high in antioxidants.
  • Turmeric: Contains curcumin, which has anti-inflammatory effects.
  • Lemon: Helps to alkalize the body and is rich in Vitamin C.
  • Cilantro: Known for its detoxifying properties.
  • Green Tea: High in antioxidants and supports liver detoxification.

Key Supplements Include: 

Vitamin D:

  • Supports Immune Function: Vitamin D is crucial for the proper functioning of the immune system. It helps to modulate the immune response, ensuring that the body can effectively fight off infections and inflammatory processes triggered by mold exposure. Adequate levels of Vitamin D can enhance the body’s ability to combat mold-related illnesses by boosting the immune system’s efficiency.


    • Restore Gut Health: Mold exposure can disrupt the balance of good and bad bacteria in the gut, leading to digestive issues and weakened immunity. Probiotics help replenish beneficial bacteria, restoring gut health and improving the body’s ability to detoxify and recover from mold exposure. They play a crucial role in maintaining a healthy gut microbiome, which is essential for overall health and immune function.

      Activated Charcoal:

      • Binds to Toxins and Helps Remove Them from the Body: Activated charcoal is known for its ability to bind to toxins, chemicals, and other harmful substances in the gut, preventing their absorption and facilitating their elimination from the body. This property makes it particularly useful in treating mold toxicity, as it can help remove mycotoxins and other mold-related compounds from the digestive system.


        • A Powerful Antioxidant that Supports Detoxification: Glutathione is one of the most potent antioxidants in the body, playing a critical role in detoxification processes. It helps neutralize free radicals and reactive oxygen species generated by mold exposure, reducing oxidative stress and cellular damage. Additionally, glutathione supports liver function, which is essential for detoxifying and eliminating toxins from the body.

          These supplements and dietary approaches help the body mitigate and recover from the adverse effects of mold exposure, ensuring a more robust immune response and effective detoxification processes.

          **Special Note: Always check with your personal physician or healthcare providor to make sure these food and supplement recommendations are safe for you.
