Review: Not a believer in miracle cures, but this stuff seems to work. - I am 72 years old and have had sharp pains in my knees for quite a few years when going down stairs, and lately have been developing some of the pains of developing arthritis. My friend suggested taking 2000 MG of this supplement for 10 days and then 1500 MG after that. So, I decided to take her advice and try it. I swear, after the 10 days, there was no more pain in my knees. One night I took a full 2-gallon watering can and a 1 gallon bottle of water downstairs at the same time and held on to the railings anticipating pains in my knees - there was no pain!! Since then, there has been no pain in my knees and they feel stronger. I later found out with some research that Ester-C helps to build joint tissue and can help to reduce the pain of arthritis. This seems to hold true since the stiffness in my finger has lessened since I have started using this supplement. I take a few supplements, but I have honestly not come across any other supplement that showed any results so quickly. I am a believer in this one, and it is good for much more than the immune system. The only downside I can think of is the size of the pill. It's huge, and it sometimes takes me a couple of tries to swallow it. I am also giving this supplement to my 98-year-old mother, but for her, we crush it and add it to her supplement cocktail. UPDATE 11/24/18: I have been taking Ester-C for 2 months, and the pain in my knees is completely gone as well as the shakiness I used to have in my knees when I went down stairs. I have also noticed that my finger joints are no longer locked when I get up in the morning, and the sharp pains I had in one of my fingers has not been happening. I can't say that this supplement helps with arthritis, but I have definitely had some improvement with joint pain and locking of finger joints. UPDATE 10/18/19: I have been taking Ester-C for a little over a year, and the benefits described above are still evident. Although i still use this supplement for my 99 year old mother who gets it pulverized in a vitamin supplement, I had a hard time swallowing the huge pills. So, I found another brand that still provides 1000 mg but in a capsule. The capsule works as well for me, but I don't gag trying to swallow it. I hope this review was helpful for you. I will update the review if my opinion changes. Review: My In-Laws Were Right - Ah, the in-law recommendation. The gift you didn't ask for but weirdly can't argue with. And honestly? They nailed it this time. The big selling point here is the "no neon pee" situation. Regular vitamin C basically waves goodbye to your body the second it arrives, turning your toilet bowl into a highlighter test. Ester-C uses naturally occurring metabolites that help your white blood cells actually hold onto the vitamin C longer than a regular supplement would. So yes, the clear pee thing isn't just a fun party trick. It's a legitimate sign your body's doing something useful with it. desertcart Clinical studies back this up too, showing Ester-C can stay in your immune system up to twice as long as regular vitamin C, and one tablet a day is all you need for 24-hour coverage. Once a day. Done. No fumbling with three doses or setting alarms. The formula is also non-acidic thanks to a chemical-free manufacturing process, so it's genuinely gentle on the stomach, which is a win if regular vitamin C has ever made you feel like you swallowed a small sun. The only mild gripe? It's pricier than a generic ascorbic acid tablet. But if your body's actually absorbing the thing instead of flushing it straight out, you're arguably getting more value per pill anyway. Bottom line: the in-laws were right, and you'll have to find a way to live with that. Great supplement, boring side effects, solid immune support. Take it, don't overthink it. ## Features - Ester-C tablets give you immune system support at the cellular level for up to 24 hours to maintain a healthy immune system (1); Ester-C is non-acidic and gentle on your stomach so you can comfortably take it every day - Ester-C tablets give your immune system the support it needs while also providing your body with antioxidant vitamin C to help fight free radicals (1); One tablet a day can give your body the immune support it needs 24/7 (1) - Ester-C also contains C-Sorb which is a citrus bioflavonoids complex; Ester-C along with C-Sorb & naturally occurring metabolites works synergistically to enhance the retention of Vitamin C in your body to support your immune system for 24 hours (1) - Ester-C 1000mg tablets provide the immune support you can count on all day every day (1); A daily dose of Ester-C tablets gets absorbed into your white blood cells and stays there for up to 24 hours which is longer than regular Vitamin C supplements (1) - Ester-C is manufactured without chemicals to neutralize pH which means it's non-acidic & gentle on your stomach (1) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0013FYHSW | | Age Range Description | Adult | | Allergen Information | Sulphur Dioxide | | Best Sellers Rank | #2,967 in Health & Household ( See Top 100 in Health & Household ) #21 in Vitamin C Supplements #379 in Sales & Deals | | Brand | Ester-C | | Brand Name | Ester-C | | Color | N/a | | Customer Reviews | 4.7 out of 5 stars 20,850 Reviews | | Diet Type | Vegetarian | | Dosage Form | Tablet | | Flavor | Unflavored | | Global Trade Identification Number | 00025077169825 | | Item Dimensions | 5.5 x 3 x 3 inches | | Item Form | Caplet | | Item Highlight | Immune System Support | | Item Weight | 7.36 ounces | | Manufacturer | American Health | | Manufacturer Part Number | 16982 | | Model Name | Ester C Vitamin 1000mg Coated Tablets | | Model Number | 56027 | | Number of Items | 1 | | Primary Supplement Type | Vitamin C | | Product Benefits | Immune Support | | Specific Uses For Product | Antioxidant,Healthy Immune System,Immune Support,Immune System | | UPC | 025077169825 | | Unit Count | 120 Count | ## Product Details - **Brand:** Ester-C - **Diet Type:** Vegetarian - **Flavor:** Unflavored - **Item Form:** Caplet - **Primary Supplement Type:** Vitamin C ## Images ![Ester-C Vitamin C 1000 mg Coated Tablets, 120 Count - Image 1](https://m.media-amazon.com/images/I/618EiiNmkaL.jpg) ![Ester-C Vitamin C 1000 mg Coated Tablets, 120 Count - Image 2](https://m.media-amazon.com/images/I/71fd46vqAlL.jpg) ![Ester-C Vitamin C 1000 mg Coated Tablets, 120 Count - Image 3](https://m.media-amazon.com/images/I/61sYGVssgwL.jpg) ![Ester-C Vitamin C 1000 mg Coated Tablets, 120 Count - Image 4](https://m.media-amazon.com/images/I/61V0SwneAOL.jpg) ![Ester-C Vitamin C 1000 mg Coated Tablets, 120 Count - Image 5](https://m.media-amazon.com/images/I/51+inOHTkwL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: what are the ingredients ? why aren't the ingredients shown?** A: Most products like this dont have animal sources depending on the company where it is made and what other products they make but this product used to be good but they changed it and made the bioflavnoid complex weaker which is wrong for every 500 mg of Vitamin C there should be at least 100mg of the bio complex. this product used to have 200mg of the bio- complex for the 1000mg pills and it doesnt now and this is what makes the vitamin C effective as an anti inflammatory and immune stimulant So this product isnt good now **Q: Is dose two tablets to get 1000 mg C?** A: No! 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 ### ⭐⭐⭐⭐⭐ Not a believer in miracle cures, but this stuff seems to work. *by J***. on October 10, 2018* I am 72 years old and have had sharp pains in my knees for quite a few years when going down stairs, and lately have been developing some of the pains of developing arthritis.
