Vitamin C Number One For My Family! This excellent vitamin shows no negative effects on my stomach. I take it and give it to my family at the first sign of a cold; typically one or two capsules help prevent the cold from developing. It's also helpful during gum issues, like bleeding or early signs of periodontitis.

Quick recovery aid
Excellent!!! I take vitamin C regularly, one capsule each morning. I hardly ever get sick now, and when I do, it usually passes within three days without fever or severe throat pain. I feel great and experience no weakness. I'm on my second can already; this one suits me perfectly.

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!

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!
8
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.
7.5
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.

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.
