Our exploration into the effects of vitamin A, particularly its active form known as retinoic acid, revealed some interesting insights regarding allergies. Vitamin A plays a key role in our immune system by helping to regulate immune responses, which is crucial for managing allergic reactions.
Research indicates that retinoic acid can promote the development of regulatory T cells, which are essential for maintaining balance in our immune system. These T cells help to suppress excessive immune responses that can lead to allergies. Additionally, they assist in managing inflammatory responses, which is particularly important for conditions like asthma and allergic reactions.
Notably, studies have shown that levels of retinoic acid are often lower in individuals suffering from asthma and allergies. Moreover, introducing retinoic acid as a treatment has been found to alleviate symptoms associated with allergies and reduce airway inflammation. This suggests that boosting retinoic acid levels in the body might be a promising therapeutic approach for those dealing with allergic conditions.
Overall, we conclude that vitamin A—through its derivative retinoic acid—holds significant potential for improving allergy management by enhancing immune regulation.

Vitamin A shows promise for allergies
Mould allergen Alt a 1 spiked with the micronutrient retinoic acid reduces Th2 response and ameliorates Alternaria allergy in BALB/c mice.
We investigated the effects of retinoic acid (RA), a form of vitamin A, on allergies, particularly focusing on the mould allergen Alt a 1. By examining how RA interacts with this allergen, we aimed to understand if it could help alleviate allergic reactions.
Our study involved assessing the RA and Alt a 1 complex in various settings, including lab tests with immune cells from individuals allergic to Alternaria, and experiments using sensitized mice. We found that when Alt a 1 was bound to RA, it significantly decreased certain immune responses associated with allergies, particularly the release of a key marker called IL-13 from immune cells.
Interestingly, this RA complex reduced the allergen's ability to bind to IgE, the antibody responsible for allergic reactions, suggesting that RA may mask allergic triggers. In our mouse experiments, those treated with the RA-bound allergen had fewer severe allergic reactions compared to those treated with the regular allergen.
Overall, our findings point towards the potential of using RA in therapies aimed at managing Alternaria allergies, suggesting a new, promising strategy for enhancing allergic immunotherapy.

9cisRA alters dendritic cell function
9-cis-Retinoic acid induces a distinct regulatory dendritic cell phenotype that modulates murine delayed-type allergy.
We explored the impact of 9-cis-retinoic acid (9cisRA) on dendritic cells and their role in handling delayed-type allergies, particularly in hand eczema. Through our investigation, we found that 9cisRA creates a unique type of dendritic cell that plays a crucial part in reducing allergic responses.
These modified cells were shown to promote the formation of regulatory T cells, which help calm inflammation. However, while 9cisRA aids in adjusting immune responses, the study reveals these effects may not be strong enough to significantly improve allergic conditions on their own.

Encapsulated vitamin A improves immunity
Liposome encapsulated all trans retinoic acid (ATRA) has enhanced immunomodulatory and inflammation reducing activities in mice model.
We explored the effects of all trans retinoic acid (ATRA), a form of vitamin A, on the immune system and inflammation using a mice model. Encapsulating ATRA in liposomes improved its effectiveness compared to free ATRA.
Our findings revealed that both forms increased immune responses, but the encapsulated version showed stronger immunostimulatory and anti-inflammatory effects. This was demonstrated through various parameters, like antibody levels and responses to inflammation. While both types showed benefits, liposome-encapsulated ATRA emerged as the superior option in managing immune and inflammatory conditions in the studied mice.
25,000 IU is a high dose but suitable for my allergies and atrophoderma. Initially, I had skin breakouts, but after a day, my skin improved. Within two weeks, facial inflammation cleared up.

Allergies are the body's immune system responses to substances known as allergens, which can be harmless in most individuals. When a person with allergies encounters these allergens, their immune system mistakenly identifies them as a threat and launches a response. This can lead to symptoms ranging from mild, such as sneezing, itching, and rashes, to severe reactions known as anaphylaxis, which can be life-threatening. Common allergens include pollen, pet dander, certain foods like nuts and shellfish, insect stings, and medications.
Managing allergies often involves avoiding known allergens and using medications such as antihistamines or corticosteroids to alleviate symptoms. In some cases, doctors might recommend allergy shots or immunotherapy to help patients build tolerance over time. If you suspect you have allergies, consulting with a healthcare professional for proper diagnosis and treatment options is crucial. Understanding your triggers and how to live with allergies can significantly improve your quality of life.
Vitamin A is a fat-soluble vitamin that's essential for several critical bodily functions, including vision, immune response, and cell differentiation. It comes in two primary forms: preformed vitamin A (retinol) found in animal products like liver, fish, and dairy, and provitamin A carotenoids, primarily found in colorful fruits and vegetables such as carrots, sweet potatoes, and spinach. The body can convert carotenoids into retinol, making these plant sources a valuable dietary option, especially for those following a vegetarian or vegan lifestyle.
Aside from its role in maintaining healthy vision—particularly in low-light conditions—vitamin A plays a significant role in skin health and the functioning of the heart, lungs, and kidneys. It also supports the immune system by promoting the development and function of white blood cells. While it's uncommon to experience a deficiency in countries where a balanced diet is accessible, a lack of vitamin A can lead to serious health problems, including night blindness and increased susceptibility to infections. In contrast, excessive intake of vitamin A, particularly through supplements, can be toxic and lead to several health issues, making it crucial to maintain a balanced intake.
Based on user reviews, the timeframe to experience results from taking vitamin A for allergies can vary, but many users report noticeable improvements within a week to two weeks of starting the supplement. For instance, one user shared that their long-term cold allergy vanished just a week after taking vitamin A, demonstrating significant relief in a short period Read Review. Others have experienced improvements over a slightly longer duration; one noted that facial inflammation cleared up within two weeks of starting the vitamin Read Review.
However, while some users have hailed the benefits of vitamin A for their allergy symptoms, others have reported adverse effects, which suggests individual responses may vary widely. For example, one reviewer experienced worsening eczema and asthma symptoms, urging caution regarding dosage Read Review. Overall, while many found relief relatively quickly, it is recommended to monitor one's body's response to the supplement closely when beginning a new regimen.
Scientific research indicates that vitamin A and its active form, retinoic acid (RA), may offer potential benefits for managing allergies. One study revealed that RA can promote the development of regulatory T cells, essential for controlling the immune responses associated with allergies, thereby helping to reduce symptoms related to asthma and other allergic reactions [1]. Furthermore, RA was demonstrated to significantly reduce immune responses linked to specific allergens, such as the mould allergen Alt a 1, suggesting it could mask allergic triggers and lessen severe reactions in experimental models [2].
However, not all research is in full agreement regarding the effectiveness of vitamin A for allergy management. Some studies indicate that while vitamin A could potentially protect against certain allergic conditions, it may also increase the risk of atopy, complicating its reliability as a treatment [3]. Additionally, while specific forms of retinoic acid have shown promise in improving immune responses and alleviating allergic symptoms, they may not be sufficient on their own to significantly improve allergic conditions without additional interventions [4]. Therefore, while vitamin A holds potential in allergy management strategies, further research is necessary to clarify its effects and efficacy.
Many users report notable improvements in their allergy symptoms and skin conditions after taking vitamin A. For instance, one user found their years-long cold allergy vanished within a week of starting the supplement, attributing this rapid relief to how vitamin A effectively targets mucous membranes Read Review. Others have shared experiences of skin conditions improving significantly; one user noted that their facial inflammation cleared up within two weeks, resulting in better overall skin health that they previously only achieved with injections Read Review. Furthermore, users have mentioned that vitamin A has alleviated various chronic symptoms like dry skin and nasal discomfort, showing its multifaceted benefits for allergy sufferers Read Review.
However, while many users felt significant relief, individual responses to vitamin A may vary. Some users have reported adverse effects, such as worsened eczema and asthma symptoms, which highlights the importance of caution, especially when starting on higher doses Read Review. Overall, while numerous users experienced positive changes in their allergy symptoms and skin conditions, it is advised that newcomers to the supplement closely monitor their body's reactions.
Based on user reviews, there is a consensus that combining vitamin A with other supplements, particularly vitamin E, may enhance its effectiveness in managing allergies. One user reported that pairing vitamin A with vitamin E led to better results, especially in alleviating skin conditions and allergies Read Review. Many users have mentioned significant improvements in their allergy symptoms and overall skin health after incorporating vitamin A, suggesting that it works well in conjunction with other supplements aimed at boosting overall wellness and tackling allergic reactions Read Review.
However, caution is also advised when introducing vitamin A into a supplement regimen. Some users experienced adverse reactions, including worsening eczema and asthma symptoms, which may suggest that careful monitoring is essential when combining supplements Read Review. Therefore, while many have found success using vitamin A for allergy relief—both on its own and in combination with other supplements—individual responses can vary significantly.
Based on user reviews, the right dose for Vitamin A in treating allergies varies, but some report success with higher doses, such as 25,000 IU. For example, one user mentioned that this dose worked well for both their allergies and skin condition, despite initial skin breakouts that improved quickly thereafter Read Review. Another user echoed a similarly positive experience, noting that two doses significantly alleviated their cold allergies in just one week Read Review.
However, not all users had an equally positive response. One individual experienced worsening symptoms of urticaria and asthma, leading them to stop taking Vitamin A due to concerns Read Review. This suggests that caution is needed when considering high doses, as some users advise moderation and emphasize personal tolerance levels Read Review. Ultimately, while many users found Vitamin A to be effective for their allergies, it is crucial to tailor the dosage to individual health needs and responses.
