It's already 1000 mg. There are some pkgs that come as 500 mg that say take twice a day. It is better to take 500 mg @ am and another 500 mg @ pm. Anything over 500 mg at a time just gets wasted out into your urine, but it's cheaper to buy the 1000 mg and cut it in half. When taking this vitamin I find I never get sick other than that once a year spring into summer season change! Then it's so mild and moves on so quickly in just a couple of days. Hope this helps! Also, when I stopped taking them I found I got sick often and weeks at a time! **Q: İs it blood thinner ,like aspirin, for example ?** A: Ester-C is not known to contain blood thinning properties. However, as a manufacturer of dietary supplements, it is not our intention to prescribe or give medical advice. Should you require advice for any particular health condition, we recommend you consult with your physician or other healthcare practitioner. **Q: when does this expire?** A: I just got mine during the coronavirus situation. Mine expires 2/24, and it is only April, 2020. Very happy with the expiry date. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The 20th time purchasing this product Simply put, it works! *by J***. on March 22, 2026* This is the best Vitamin C tablet out there. To the people who whine about the size of the vitamin GIVE ME A BREAK, cut the darn vitamin in half, it is one of the highest rated based on quality, no stomach issues,consistency etc... Simple resolution to a simple issue. ### ⭐⭐⭐⭐⭐ Great way to increase your vitamin C intake *by M***N on February 19, 2026* I have used Ester C for many years and I love it for the ability to not upset my stomach, but give me the daily does of Vitamin C I like to take. Caution- these pills are very large so if you have issues with swallowing larger pills, this is not the one for you, stick to the 500mg tablets. ### ⭐⭐⭐⭐⭐ FIVE STARS! *by J***J on September 30, 2016* This is the best vitamin C I drink because its good for my stomach. I had the stomach surgery and it is non acidic and it helps especially since I have a history of ulcers and anything I can do to help is better than taking a cheaper generic brand of vitamin C. Its smooth to take and it works. Also a tip that I found which is irrelivent but it works for me. I get cold sores. But I don't have break outs any more and don't get them as I use to ALL the time. Maybe once every 3 years. When I feel one coming on. That tingling feeling. Take 1000 mg vitamin C in morning 1 1000mg Lysine and at night take 1000 mg of vitamin C and 1000mg Lysine. I know its a lot. Your body will extract it (don't forget to drink water) and watch youll feel the tingle a bit might see a bit red in the spot the soar will come out but it will never FULLY come out and show the world look at my face. It really works. I got other remedies that works great. Home remedies that I have tried on my own. I passed this to a friend of mine and tried it and couldn't believe it worked. Always keep vitamin c and Lysine on hand. Youll notice in the vitamin aisle lysine is always empty. Ask yourself why......maybe they know the trick. But it works. I tried all the other remedies. This one really works. My mom suffers from them a lot and does this and never has a break out. Especially in the line of work she don't want it to show. But this vitamin C is good for your stomach and dissolves fast. My levels (blood) always come back good. SO yes its worth it. I use to buy at Costco a BIGGER bottle cheaper price but they will not carry no more. So this is the best price I found on the net. :) Hope this helps. ## Frequently Bought Together - Ester-C Vitamin C 1000 mg Coated Tablets, Immune System Booster, Stomach-Friendly Supplement, 120 Count - Ester-C 500 mg 24 Hour Vitamin C Tablets for Immune Support, Vitamin C Supplement, 90 Count - Centrum Silver Women's Multivitamin for Women 50 Plus, Multivitamin/Multimineral Supplement with Vitamin D3, B Vitamins, Non-GMO Ingredients, Supports Memory and Cognition in Older Adults - 200 Ct --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/4956013-vitamin-c-1000-mg-coated-tablets-immune-system-booster-stomach](https://www.desertcart.us/products/4956013-vitamin-c-1000-mg-coated-tablets-immune-system-booster-stomach) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-22*
