Top Medical Research Studies

We conducted a thorough evaluation of how vitamin C, when combined with pleuran, impacts asthma control and respiratory issues in children suffering from perennial asthma. The study was meticulously designed as a double-blind, placebo-controlled trial involving 230 children aged 7 to 17 years. This means that neither the participants nor the researchers knew who was receiving the active treatment or the placebo, ensuring the findings were reliable.

The results were promising, especially for children under 12 years. They showed significant improvements in asthma control compared to those receiving only the placebo treatment. Meanwhile, older children (12 years and above) experienced fewer respiratory infections with the combination treatment. Overall, by the end of the 48 weeks, a majority of children on the pleuran and vitamin C treatment reported better asthma control compared to those on the placebo.

While the combination of pleuran and vitamin C was indeed beneficial for managing asthma, we must note that the study did not specifically isolate the effect of vitamin C alone on allergies or asthma. Thus, it is hard to draw definitive conclusions about vitamin C's effectiveness independently from pleuran. However, the approach suggested that using these supplements together could offer a helpful boost in managing asthma symptoms.

Cold prevention
High dosage of vitamin C as ascorbic acid (1000 mg) with added citrus bioflavonoids and rutin enhances its effect. I usually purchase this before the cold season and take 1000 mg daily at the first signs of illness. This dosage helps alleviate cold symptoms but should not be taken daily for more than 2-3 weeks. A continuous dosage should be between 250-500 mg to avoid issues.

Immune enhancement
A dose of 1000 mg works well! My husband and I took one capsule daily for four months during autumn to spring. There were no allergies or rashes, and we took it after meals to avoid stomach irritation. We combined it with zinc for optimal results and plan to stock up for next season.

Frequently Asked Questions

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 C, also known as ascorbic acid, is a water-soluble vitamin that plays a critical role in numerous bodily functions. As an essential nutrient, it contributes to the growth and repair of tissues in the body, and it is vital for the production of collagen, an important protein that helps maintain skin, cartilage, tendons, ligaments, and blood vessels. Additionally, Vitamin C acts as a powerful antioxidant, which means it helps combat free radicals—unstable molecules that can cause oxidative stress and contribute to various chronic diseases.

Moreover, Vitamin C enhances iron absorption from plant-based foods, making it a vital component for those following vegetarian or vegan diets. While many people get sufficient Vitamin C from a well-balanced diet that includes fruits and vegetables like oranges, strawberries, kiwi, broccoli, and bell peppers, some individuals might require supplementation. It's generally recommended to stay within the daily intake guidelines, as excessive consumption can lead to gastrointestinal disturbances. Overall, Vitamin C is not just a skincare celebrity—it's a fundamental part of maintaining overall health and well-being.

Vitamin C is often touted for its potential to bolster the immune system, and some studies suggest it may help mitigate allergy symptoms. As an antioxidant, Vitamin C can help combat oxidative stress, which can exacerbate allergic reactions. Furthermore, its anti-inflammatory properties may assist in reducing nasal congestion and other allergy-related discomforts. However, it's important to note that while Vitamin C can be a beneficial supplement for some, it is not a cure for allergies and should not replace prescribed treatments or medications.

If you're considering adding Vitamin C to your regimen for allergy relief, it’s advisable to consult with a healthcare professional. They can provide personalized advice and determine the appropriate dosage based on your specific health needs. While increasing your intake of Vitamin C-rich foods like oranges, strawberries, and bell peppers is a safe approach, relying solely on supplements without professional guidance may not be the most effective strategy for managing allergies.
