Vitamin A reduces rash severity

Disease manifestations of canine distemper virus infection in ferrets are modulated by vitamin A status.

Most Relevant Research

We explored how vitamin A affects rash severity in ferrets infected with canine distemper virus (CDV). Our study involved both vitamin A-replete and vitamin A-depleted ferrets, assessing the impact of high-dose vitamin A on CDV symptoms.

Interestingly, ferrets that received vitamin A did not develop typical disease symptoms and only showed a mild rash, highlighting the vitamin's protective effect. The findings suggest that supplementing with vitamin A can significantly mitigate rash and other illness manifestations, reinforcing its potential benefits against similar viral infections in humans.

Vitamin A deficiency worsens lupus nephritis

Hypovitaminosis A Drives the Progression of Tubulointerstitial Lupus Nephritis through Potentiating Predisease Cellular Autoreactivity.

Most Relevant Research

We examined the impact of vitamin A deficiency (VAD) on the progression of lupus nephritis in a mouse model. By inducing VAD during pregnancy or after weaning, we discovered that both methods significantly worsened the condition, leading to higher mortality rates.

Interestingly, restoring vitamin A levels after weaning reduced mortality. This suggests that VAD accelerates lupus nephritis through increased immune cell activation and autoantibody production. However, effects were less pronounced when VAD was introduced post-weaning. Overall, the study highlights the potential dangers of vitamin A deficiency in autoimmune diseases.

Skin improvement

Most Useful Review

Recommended for skin. After careful study, I compared other drugs and ordered beta-carotene from Solgar. I take one capsule, and on sunny days, I take two. I tan beautifully, without burns. Beta-carotene, unlike vitamin A (retinol), is non-toxic, and overdose isn't an issue; you will notice effects swiftly (yellowing of the skin). It accumulates in the skin and can be converted to retinol as needed, acting as an antioxidant. Unlike retinol, beta-carotene works slowly, so patience is key; I take it daily for at least a month. I've struggled with problem skin, including redness and pimples, but now my skin is smooth and even. I still can't believe it. Highly recommend.

High vitamin A causes bone pain

Vitamin A toxicity presenting as bone pain.

Most Relevant Research

We examined a case of a 4-year-old boy who experienced severe bone pain and related symptoms after taking high doses of vitamin A for three months. Despite typical liver-related complications usually associated with vitamin A toxicity, he presented with significant musculoskeletal issues and skin changes. Following the discontinuation of vitamin A, the boy showed a remarkable recovery within two months. This case highlights that excessive vitamin A intake can lead to serious bone pain and other health problems, though he did not develop liver disease as expected.

Vitamin A modulates heart repair

Modulation of bone marrow haematopoietic stem cell activity as a therapeutic strategy after myocardial infarction: a preclinical study.

Most Relevant Research

We investigated the impact of vitamin A in treating heart disease, specifically after a myocardial infarction (MI). Our study focused on over 150 cardiac surgery patients, with a particular emphasis on the effects of vitamin A on bone marrow stem cells. We discovered that MI led to harmful changes in these stem cells and that vitamin A, specifically its metabolite 4-oxo-retinoic acid, helps reduce inflammation by calming the stem cells. This approach could improve heart function in the long run after an MI.

Vitamin A and allergy management

Retinoic Acid (RA): A Critical Immunoregulatory Molecule in Asthma and Allergies.

Most Relevant Research

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.

Eliminated sun allergies

Most Useful Review

Great skin preparation for sun exposure. I've suffered from sun allergies for ages, including a red rash and tiny freckles. After reading about beta-carotene, I started using Solgar in April and drank it for three months. It appears to completely rid me of these sun-related allergies.

Nausea details

Vitamin A reduces pregnancy nausea

Vitamin A or beta-carotene supplementation reduces symptoms of illness in pregnant and lactating Nepali women.

Most Relevant Research

We conducted a double-masked, placebo-controlled trial involving 15,832 Nepali women to explore how vitamin A and beta-carotene supplementation affects pregnancy-related nausea and overall illness symptoms. Our observations showed that while there was no noticeable impact during the early stages of pregnancy, vitamin A supplementation made a significant difference in late pregnancy.

Specifically, we found that women who received vitamin A experienced a reduction in nausea. Additionally, symptoms such as faintness and night blindness were also less prevalent in those women. Beta-carotene supplementation did not yield the same benefits for nausea, highlighting the unique role of vitamin A in managing these symptoms.

Moreover, supplementation with vitamin A contributed to a shorter labor duration, which is promising for expectant mothers. It also helped reduce the postpartum risks of conditions like night blindness and loose stools. Overall, our findings indicate that ensuring adequate vitamin A intake can be important for improving reproductive health in women, particularly in areas with limited healthcare access.
