Easy to swallow, Easy on your stomach, Easy on your wallet!

Posted by Sickness-ELIMINATOR on Sep 11, 2016 | Verified Purchase

I've been taking 3000mg of vitamin C daily for many years, along with a variety of other important vitamins and supplements. These are the best C I have found. They contain the appropriate levels of bioflavonoids and will not irritate your stomach. I strongly recommend these to anyone serious about supplementation. . .

I've used megadoses of vitamin c for years. When I'm at home I use a powder, but at work I carry these. Truly an amazing product! They are formulated to break down quickly, without stomach upset, so they can be taken on an empty stomach if desired. I believe that nutritional supplements saved my life. I've tried a lot of products, and I know what works and what doesn't. My reviews are honest, straighforward, and based on my experience. Read my other reviews to quickly learn from my three decades of research and experimentation.

Wonderful alternative to regular C

Posted by Reviewer3335982 on Jun 16, 2009 | Verified Purchase

It's hard to find a good ester-C compound with bio. I take this because my family has a high rate of kidney stones. Regular C has been the culprit in forming them. This is a great alternative for those who suffer from kidney stones. Take this along with some gravel root and you'll live stone-free.

Best Vit C

Posted by Lauryna on Dec 05, 2016 | Verified Purchase

Its very gentle to my stomach, plus you get bioflavonoids! Im taking only one tablet per day, becouse 1000mg its too strong for body, too high vit C doses can damage.

Thanks for your feedback!

diminished TINNITUS

Posted by x-tine on Jun 05, 2011 | Verified Purchase

My mom's tinnitus has reduced to less than half of what it was by taking this product. This is the same type of vitamin C and bioflavinoids found in another more expensive product that is packaged especially for tinnitus sufferers and sold over the internet (not at iherb). I thought she should give this a try, and it really helped her! And the side benefit is that this combo of ingredients was recently found to reduce inflammation.

Non-acidic acid 🍋 ❔Did you know ascorbic acid has the same strong effect on the digestive tract as vinegar. In principle, there are no problems in this. We use vinegar quite often when cooking. But, this is not a problem if you have a healthy stomach. Those who suffer from digestive tract diseases can hardly boast of the use of vinegar without any consoquenses. If there are diseases of the digestive tract, ascorbic acid can irritate the gastric mucosa, as well as vinegar and other acids. ✅In such cases, instead of the usual ascorbic acid, it is better to take one in which the acidity is already neutralized, which makes it safe for the digestive system. Nowadays exist a patented composition with vitamin C in the form of Calcium Ascorbate called "Ester C" - it is a calcium salt of ascorbic acid. https://ua.iherb.com/…/American-Health-Ester-C-500-m…/14309… And Ester C is unique in a way that it remain in the body 4 times longer than normal vitamin C - thanks to the fact that vitamin C is released from the pill gradually. While the usual vitamin C is excreted from the body within 2-3 hours. PH for comparison: - Ascorbic acid 1 g - 2.4 - Vinegar 6% - 2.4 - Vinegar 9% - 2.3 - Ester C ~ 7 Некислая кислота ❔Знали ли вы, что аскорбиновая кислота по своему влиянию на ЖКТ такая же сильная, как уксус. В принципе, в этом нет никаких проблем. Мы довольно часто используем уксус при приготовлении пищи. Но, это не есть проблема в том случает, если у вас здоровый желудок. Те, кто страдает заболеваниями ЖКТ наврядли могут похвастаться употреблением уксуса без печальных последствий. Если есть заболевания ЖКТ, аскорбиновая кислота может раздражать слизистую желудка, также как и уксус и другие кислоты. ✅Вот в таких случаях вместо обычной аскорбиновой кислоты лучше принимать ту, в которой кислотность уже нейтрализована, что делает ее безопасной для пищеварительной системы. На сегодняшний день известен запатентованный состав с витамином С в виде Аскорбата Кальция под названием «Ester C» - это кальциевая соль аскорбиновой кислоты. https://ua.iherb.com/…/American-Health-Ester-C-500-m…/14309… А еще Ester C уникален тем, что он удерживается в организме в 4 раза дольше, чем обычный витамин С – благодаря тому, что витамин С высвобождается из таблетки постепенно. В то время, как обычный витамин С выводится из организма в течении 2-3-х часов. PH для сравнения: - Аскорбиновая кислота 1 гр – 2,4 -Уксусноая кислота 6% - 2.4 -Уксусная кислота 9% - 2.3 - Ester C ~7
