Ester-c calcium ascorbate is a unique and patented form of vitamin c. It is made using a proprietary, water-based manufacturing process which results in a ph neutral product that contains naturally occurring vitamin c metabolites. These metabolites activate the vitamin c molecules, making it easier for the body to transport them from cell to cell for numerous health benefits. One clinical study showed that ester-c increased vitamin c levels in the body. 1 White blood cell levels of vitamin c were elevated in subjects receiving ester-c when measured after initial dose. The presence of key metabolites such as threonate may contribute to this increased level and retention of vitamin c by the cells. In one published study, individuals sensitive to acidic foods were given one gram of vitamin c as ascorbic acid or as ester-c. Subjects reported heartburn significantly more frequent and severe after intake of ascorbic acid and subjects rated ester-c as tolerated very good -- significantly more than ascorbic acid. 2 So for anyone who has difficulty tolerating vitamin c, it's comforting to know that ester-c is non-acidic and gentle on the stomach. The main benefit of ester-c is its quick absorption and retention in the immune system. Enhanced absorption with c-sorb non-acidic and stomach friendly gives you powerful immune system support gives the body antioxidant protection.

My doctor actually recommended this specific brand of vitamin C supplement. These vitamins are non-GMO, gluten free, suitable for vegetarians, sugar free, soy and wheat free, lactose free, stomach friendly, and no added flavors or sweeteners. This is one of the best vitamins I’ve ever tried. I have had zero issues with this vitamin. A lot of times vitamins do upset my stomach or make me a little queasy. Ester-C is a gentle vitamin that packs 500mg of vitamin C in each tablet. My only complaint is that the serving size is 2 tablets. I hate that they cannot make these into just a one pill serving size. Other than that, they are perfect.

Our family has been a decade-long fan of Ester-C brand of vitamin C. Why? 1. It doesn’t upset our stomach, unlike ascorbic acid. Non acidic at all. 2. Quality ingredients. It also has citrus bioflavanoids, aside from the main component of calcium ascorbate. 3. Affordable.We buy the 1,000mg tablet for max potency at just one dose. It is bigger in size and may be harder to swallow for some. Vit C is water-soluble and any excess is urinated.Vit C is also helpful for iron absorption and collagen production.My dad recently was at the onset of having colds and flu and taking Vit C 1000mg 3x a day, along with other supplements, helped stopped his onset of flu. He was well by day 2 and didn’t have sore throat and flu, like he normally would. Amazing!Consider giving ... MoreOur family has been a decade-long fan of Ester-C brand of vitamin C. Why? 1.

Easy to swallow, once a day tablet. You get your full dose if Vitamin C that stays in your system for 24 hours because the type of Vitamin C used in this supplement is fat soluble not water soluble. The body will hold it longer. I have been taking this supplement for several years now and it does work! I have not gotten sick at all. No flu, no cold. This is an excellent supplement to keep in your daily regiment.
I started taking vitamin C recently. This is my second bottle. How did I choose this particular vitamin C? On the advice of my sister, she knows a lot about all the pills, so there was no doubt, I took them immediately and do not regret it!I take vitamin C on a regular basis. And if I feel weak, sick, I immediately take a double dose. Vitamin C helps our body to fight.And by the way, I got rid of the endless fatigue.The jar is bright orange, with a handy lid. 120 vitamins enough from 4 months. It tastes absolutely neutral. The tablets themselves do not smell, but from the can hear a fruity smell.Vitamin C is not only to strengthen the immune system, but also strengthens bones, helps absorb other vitamins and minerals, goes to the formation of thyroid hormones, ...

The pills are just too big for me to swallow. Every time I take it I fear I might choke (taking with water does not help much). For the few times I was able to ingest it, it worked quite well though as I felt that colds and allergies were at bay. But definitely did not continue the rest of the bottle as it hurts my throat each time which is not worth it. I hope they make these in more ingestible tabs as I believe the formula is excellent.
I've been using this ester vitamin C supplement for quite some time. It seems just as good an antioxidant as the previous brand of vitamin C which I was using for years. However, the price is more reasonable and the product seems similar. It's easy to store and swallow. So far it seems to be helping me keep my immune system in check, I haven't caught a cold in a long time. I have absolutely no upset stomach, no acidity, and I take one every day.
From my experience so far, Ester-C is a powerful vitamin. I'm prone to colds, sniffles and sinus issues as soon as weather changes in the Fall. I feel like my immunity has gotten stronger... and that I have defense in my system. Time will tell since it's only November but looking forward to feeling well this winter.I used to take (2) 500mg a day. When I found 1000mg on iHerb I'm happy to only have to take one tablet a day. I have not had any stomach issues either which is also wonderful!
