We investigated how exposure to ultrafine particles (UFPs) in cold and humid environments impacts respiratory health. Using a controlled study with male Balb/c mice, we found that exposure to carbon black nanoparticles worsened lung function and increased inflammation and oxidative stress.
Notably, the combination of UFPs and cold-humid conditions intensified these adverse effects. However, when we administered Vitamin E, it helped reduce these harmful impacts. This suggests that Vitamin E could be a potential protector against indoor air pollutants, offering insights for healthier living spaces.

I switched to this vitamin E three months ago. My cold sensitivity was so extreme that even in summer, my hands and feet felt cold. However, this summer, my feet are warm even when barefoot, which surprises my family. Additionally, I used to rely on painkillers for period discomfort, but since taking this, I've had no need for them. Switching was indeed the right decision.

With worsening Raynaud's symptoms turning my fingers white in the cold, I started taking Vitamin E following the Fujikawa Method. After about a month of 2-3 tablets daily, the whitening reduced significantly. My symptoms, which intensified over 10 years, are now improving remarkably. Though I take other supplements, the quick positive change is surprising. My menstrual cycle has also stabilised, enhancing my overall quality of life.

Significant cold improvement
I take three tablets daily and after a year, my sensitivity to cold has improved significantly. Though it's pricey, I plan to keep taking it.
Cold is a term that refers to a state of low temperature, often associated with a perceptibly chilly environment or the sensation of being cool to the touch. Scientifically, cold is relative to the presence and movement of heat, which is a measure of energy within matter. In everyday terms, we experience cold through weather changes, such as during winter months, and it can also be described in the context of specific temperature ranges – for example, temperatures below 32 degrees Fahrenheit (0 degrees Celsius) generally signify freezing conditions, which can impact outdoor activities, personal comfort, and various ecological systems.
Moreover, the sensation of cold is not solely dependent on temperature; factors like humidity and wind chill can enhance the feeling of coldness. When discussing cold in terms of human health, prolonged exposure to cold conditions can lead to hypothermia or frostbite if body heat is not effectively maintained. Hence, it's crucial to dress appropriately and take necessary precautions during colder months to prevent adverse effects. Understanding the concept of cold can help individuals better prepare for seasonal changes and ensure their comfort and safety.
Vitamin E is a fat-soluble nutrient that plays a crucial role in various bodily functions, primarily acting as an antioxidant. This means it helps to neutralize free radicals, which are unstable molecules that can cause oxidative stress, leading to cellular damage. Vitamin E is not just one compound, but a group of several related compounds, with tocopherols and tocotrienols being the most studied forms. These compounds are found in various foods, including nuts, seeds, and green leafy vegetables, making it relatively easy to obtain sufficient amounts through a balanced diet.
Research suggests that Vitamin E may contribute to immune function, skin health, and the overall maintenance of cardiovascular health. While most people can get enough Vitamin E from their diet, supplements may be necessary for those with specific deficiencies or conditions that impair absorption. However, it’s important to consult a healthcare provider before starting any supplement regimen, as excessive intake of Vitamin E can lead to adverse effects. Overall, maintaining adequate Vitamin E levels is essential for promoting long-term health and preventing potential deficiencies.
Based on user reviews, the timeline for seeing results after starting this supplement for cold sensitivity varies widely. Many users report significant improvements in their sensitivity to cold within a few weeks to a few months. For instance, one user noted that after about a month of taking 2-3 tablets daily, their Raynaud's symptoms showed considerable improvement Read Review. Another user mentioned noticeable changes after just three months, stating their cold sensitivity reduced significantly during warmer months Read Review.
Overall, while some users have found relief in as little as a few weeks, others suggest a more gradual process with results becoming evident after several months of consistent use Read Review. It’s clear that the effectiveness of this supplement can depend on individual health factors and lifestyle, so maintaining regular intake is crucial for optimal benefits.
The research indicates that while Vitamin E may play a role in mitigating respiratory issues linked to cold and humid environments, it is not explicitly noted as a supplement for treating colds themselves. A controlled study focusing on the effects of ultrafine particles (UFPs) found that cold-humid conditions exacerbated lung function issues and inflammation in mice, but when Vitamin E was administered, it helped in reducing these adverse effects. This suggests potential benefits of Vitamin E in improving respiratory health under certain conditions [1]. However, this does not establish direct support for its efficacy specifically as a remedy for the common cold.
Users report a significant improvement in symptoms of cold sensitivity and general health after taking Vitamin E supplements. Many individuals have noted that their cold extremities, particularly hands and feet, have become noticeably warmer. For instance, one user described how their cold feet, which used to be quite debilitating, now feel warm even in summer, much to the surprise of their family Read Review. Another user, who struggled with severe Raynaud's symptoms, reported a remarkable reduction in whitening of fingers after a month of consistent usage, leading to an overall improvement in their quality of life Read Review.
In addition to alleviating cold sensitivity, users have shared broader health benefits. Many have reported enhanced blood circulation and reduced reliance on painkillers, as one user noted they no longer needed pain relief for menstrual discomfort after starting the supplement Read Review. Regular users also mention feeling healthier overall, experiencing fewer colds, and even improvements in skin and hair health Read Review. While these experiences are promising, individual results can vary, and it’s recommended for users to monitor their health closely and consult with a healthcare provider.
Users report a variety of experiences when combining this Vitamin E supplement with other vitamins for alleviating cold sensitivity. Many have found that taking Vitamin E alongside Vitamin C is particularly beneficial, as one user noted no longer catching colds while using both Read Review. Others, like a different user, emphasize the importance of integrating B vitamins into their daily regimen, observing fewer instances of illness as a result Read Review.
Additionally, some reviews highlight the positive effects of pairing Vitamin E with omega-3 supplements. One user reported they felt warm even at night without heating after starting this combination, suggesting a significant improvement in their cold tolerance Read Review. Overall, combining Vitamin E with other vitamins appears to enhance its effectiveness in supporting blood circulation and managing cold sensitivity, making users feel healthier and less prone to illness.
Based on user reviews regarding the optimal dosage of Vitamin E for managing cold sensitivity, it seems that many find success with different quantities. A common range appears to be between 2 to 5 tablets daily. For instance, some users report taking 2000 IU or 3 to 5 tablets each morning and have noticed significant improvements in their cold sensitivity and overall blood circulation (review ID: f969e4da-1488-4bc4-b100-73dc7a994ce6, review ID: a8ef0aec-88fb-4dc8-9163-b10d71a251ba). Others have successfully implemented a regimen of 2 to 3 tablets daily, noting improvements in symptoms linked to Raynaud's syndrome and menstrual discomfort as well (review ID: 562006a3-f665-47b0-9c67-3132ac87d99b, review ID: f91d5b85-8d37-42d6-b11f-854e00267c7b).
