Immunisation improved
One of my favourites! I’ve been regularly taking Vitamin C for three years, and my whole family does too, to prevent colds. This vitamin significantly enhances our immunity, particularly as I have gastritis. I take it right after breakfast, and I experience no throat problems anymore.

Strengthened immunity
An irreplaceable tool in my life. My acquaintance with vitamins, particularly through iHerb, began with this vitamin. Initially sceptical, I frequently suffered from tonsil issues—every time someone nearby sneezed, I’d catch a cold the next day. A friend recommended vitamin C. Since then, I’ve taken it year-round with breaks, and astonishingly, I haven't fallen ill. It has truly restored and strengthened my immunity. I would definitely recommend it to all!

Frequently Asked Questions

Adenoiditis is an inflammation of the adenoids, which are small masses of lymphatic tissue located at the back of the nasal cavity. These tissues play a crucial role in the immune system, particularly in young children, by helping to protect the body from infections. When the adenoids become swollen or inflamed, it can lead to a range of symptoms including nasal congestion, difficulty breathing through the nose, sore throat, and sometimes fever. Adenoiditis can be caused by various factors, including bacterial or viral infections, allergies, or chronic irritants.

In many cases, the condition is diagnosed based on medical history and physical examination, sometimes supplemented with imaging studies if necessary. Treatment typically involves managing symptoms, which may include saline nasal sprays, pain relievers, and, in recurrent or severe cases, a surgical procedure called adenotonsillectomy to remove the adenoids. If you or your child are experiencing symptoms of adenoiditis, consulting a healthcare professional is essential to determine the best course of action and ensure proper care.

Ester-C is a patented form of vitamin C (ascorbic acid) that is known for its unique formulation, which includes calcium ascorbate. This makes Ester-C less acidic than standard vitamin C, making it gentler on the stomach for those who may experience gastrointestinal discomfort from regular vitamin C supplementation. One of the key features touted by manufacturers of Ester-C is that it is better absorbed by the body and stays in the immune system longer, although scientific research on these claims can be mixed.

In addition to its purported benefits, Ester-C is often marketed as a supplement that supports immune health, collagen production, and serves as an antioxidant, helping to combat free radicals and oxidative stress. It's available in various forms, including capsules, tablets, and powders, making it easy to incorporate into your daily routine. While some users report positive effects and tolerance of Ester-C, it's essential to consult with a healthcare professional before adding any new supplement to your regimen, especially if you have existing conditions or are taking other medications.

Based on user reviews, the time it typically takes to see results from vitamin C supplementation for conditions such as adenoiditis varies. Many users report experiencing relief from cold symptoms within as little as one day after taking the supplement at the first sign of illness (Read Review). For instance, one user noted that after taking vitamin C every two hours during the onset of a sore throat, their symptoms significantly improved by the following day (Read Review).

Others have mentioned a gradual improvement over a few days, often noting that an initial high dosage helps manage symptoms effectively (Read Review). Generally, many users agree that starting vitamin C supplementation at the early signs of a cold leads to quicker recovery, suggesting that proactive use can lead to timely and effective results.

Based on user reviews, many individuals have reported significant improvements in their symptoms after starting vitamin C supplementation. Users typically note a reduction in cold symptoms, with some claiming that a simple two-capsule dosage taken at the first sign of illness can prevent a cold from developing altogether (Read Review). Others have mentioned waking up symptom-free after experiencing initial discomfort, suggesting rapid relief from cold symptoms such as sore throats and nasal congestion (Read Review).

Additionally, users highlight the general enhancement of their immune function, with some reporting an overall decrease in sick days or symptoms during cold season (Read Review). A few have noted that consistent use of vitamin C has transformed their approach to illness, allowing them to better manage colds without the need for stronger medications or antibiotics (Read Review). While the experiences vary among users, many celebrate the boost in immunity and rapid resolution of symptoms, underscoring vitamin C's pivotal role in their health regimen.

Based on user reviews, many individuals have reported successfully combining vitamin C with other supplements to enhance their response to conditions like adenoiditis. One user mentioned that they use vitamin C alongside lactoferrin and dextran, noting that this combination effectively alleviates fever and cough, making it highly recommended for overall nutrition (Read Review). Another user shared a regimen where they increased their vitamin C dosage in conjunction with other supplements to manage cold symptoms effectively, stating that they often start with larger doses at the onset of illness before tapering off (Read Review). This approach has reportedly enabled them to manage around 90% of their cold symptoms without the need for antibiotics.

Additionally, some users highlighted the importance of taking vitamin C in combination with bioflavonoids for enhanced absorption, which they found beneficial for a stronger immune response (Read Review). The general sentiment among users is that combining vitamin C with other supportive nutrients can lead to a more comprehensive strategy for managing symptoms related to adenoiditis and colds, demonstrating the potential for synergistic effects when using multiple supplements in conjunction.

Based on user reviews, there appears to be a consensus on the effective dosing of Ester C for treating adenoiditis and related cold symptoms. Many users recommend starting with higher dosages at the onset of symptoms, such as taking 2 grams (2 capsules twice a day) for the initial three days, followed by 1 gram (2 capsules) for three days, and then tapering down to 0.5 grams (1 capsule) in the final three days (Read Review). Others suggest a more straightforward approach of taking one capsule, which contains 500 mg, to meet daily requirements and effectively alleviate cold symptoms (Read Review).

Additionally, some users mention taking two capsules at once at the onset of throat discomfort, which helps them recover faster and manage cold-related symptoms effectively (Read Review). One user specifically noted that they would advise trying a dosage of 5 grams at the onset of a cold, indicating that they find it resolves issues quickly (Read Review). Overall, it seems that while individual responses may vary, many users find that a higher initial dose followed by a tapering strategy can be quite beneficial in managing symptoms associated with adenoiditis.

Cold symptoms alleviated
He coped with a cold for one day! We often overlook this vitamin, but it significantly boosts immunity. After falling ill due to a sudden shift in temperature, I didn't take Vitamin C initially, which I regretted. Once I started taking one tablet every two hours at the onset, my sore throat and headaches disappeared by the next day. This method of immediate intake proved effective, unlike previous remedies that required gargling. As the manufacturer claims a natural composition, I trust their word.

Supports immune system
I rely on 500 mg of vitamin C and 50 g of zinc twice a day whenever my throat starts to hurt or my temperature rises. It significantly aids my immune system, and by the next day, my symptoms improve. The inclusion of citrus bioflavonoids enhances its absorption, making it even more effective. I find it indispensable—highly recommend!

Effective dosage
I find it so helpful, especially at the onset of a cold. We follow a regimen: the first three days, 2 grams (2 capsules twice a day), the next three, 1 gram (2 capsules), and the final three days, 0.5 grams (1 capsule). This vitamin effectively protects cells from infection, and my throat no longer hurts.

Impressive immunity enhancement
I won't catch a cold! I've been taking this vitamin for nearly ten years. It doesn't upset my stomach and it's time-released. Since beginning this daily regimen, I've rarely fallen ill! I used to catch a cold monthly, but thanks to this supplement, I feel refreshed even if I start to notice symptoms at night. I believe it’s the strongest vitamin C available.

Reduced antibiotic use
I've been taking them for almost nine years now. A recommendation from a knowledgeable friend led me to try them, and I've found that they help my children and I manage around 90% of colds without complications. I start with larger doses at the beginning and then taper off. I’m very pleased; I rarely need antibiotics or other serious medications anymore. While a severe flu or sore throat might still require a pharmacy and a doctor, these vitamins help us manage most other issues.

Quick cold recovery
Every time I have a sore throat, I use this vitamin to recover more quickly. Combining it with lactoferrin and dextran also alleviates fever and cough, making it highly recommended and great nutrition. It’s a delight for children wary of medicine.

Strong immunity boost
The best vitamin C! Simply the best for those with gastrointestinal issues. As someone with chronic gastritis and pancreatitis, other Vitamin Cs induce nausea and vomiting, but not Ester-C. I take it twice a day after meals, and at the first sign of a cold, I take a capsule every six hours. I believe the body absorbs only 500 mg at a time, so I don’t see the benefit of higher dosages. It's beneficial to take it with bioflavonoids for better absorption. The effect is noticeable; my immunity is stronger. Considering how often I used to catch colds, this year has been much better, with mild symptoms even when catching COVID.

Improved immunity
Excellent vitamin C in a well-regulated dosage; one tablet contains 500 mg, meeting the daily requirement. During this period, using the supplement improved my immunity and relieved cold symptoms, helping with a runny nose or sore throat. I found that I recovered in just a couple of days.
8.8
Less colds
They work great! I’m allergic to citrus fruits and can’t tolerate the tingling vitamin C tablets. Instead, I use these vitamins to receive my C intake, and they help remarkably! I noticed I catch colds less frequently and recover faster. When I sense a sore throat or weakness, I take two capsules at once, and I’ve avoided getting sick. I intend to continue taking them in courses.
8.8
Effective high dosage
An excellent vitamin for those in the know. For those unfamiliar, I recommend trying a dosage of 5 grams at the onset of a cold. It resolves issues swiftly within three days, and I advise adjusting doses based on weight. I highly recommend this product.
