Since then, I have been taking a bone supplement that includes calcium and this ester-c. I have had the bone density test every other year as suggested by my doctor, and each time, my bone density has increased rather than decrease as I got older. At this point, I no longer have osteoporosis, but have been diagnosed as having osteopenia rather than osteoporosis. I am hopeful that my bone density continues to increase as I get older with continued use of these supplements.Although a vitamin C supplement may also work for this purpose, ester-c is supposed to have a better bioavailabilty and is easier on the stomach since it is less acidic. To-date, this supplement has not upset my stomach, and my bone density tests suggest that it is effective. Having done my research before taking this supplement, this is rated as a good brand and is of good quality. This supplement is a large capsule, but is easier to swallow than some of the other supplements I take.I do recommend this supplement and hope this review was helpful for you. ### ⭐⭐⭐⭐⭐ Amazon is the best!! *by on Reviewed in the United States May 14, 2026* I have tried other brands of C vitamins finding these to be very easy on the tummy. Great quality and a recommended dose is just right. The pill is easy to swallow and the ingredients are top of the line not leaving anything out. The duration they last is 2 per day which is perfect to take in the morning and not having to think about another dose until the next day. Texture is just like other capsules that are meant to be swallowed whole. Highly recommended!! ### ⭐⭐⭐⭐⭐ Excellent product *by on Reviewed in the United States August 7, 2026* Excellent product that I use to help control my allergies since the ester is a natural antihistamine. ## Frequently Bought Together - American Health Ester-C with Citrus Bioflavonoids Capsules - Gentle On Stomach, Non-Acidic Vitamin C - 500 mg, 60 Servings, 120 Count - PreserVision AREDS 2 Eye Vitamin & Mineral Supplement, Contains Lutein, Vitamin C, Zeaxanthin, Zinc & Vitamin E, 120 Softgels (Packaging May Vary) - Nature Made Vitamin B12 1000 mcg, Dietary Supplement for Energy Metabolism Support, 150 Softgels, 150 Day Supply --- ## 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/7678790-ester-c-with-citrus-bioflavonoids-capsules-gentle-on-stomach-non](https://www.desertcart.us/products/7678790-ester-c-with-citrus-bioflavonoids-capsules-gentle-on-stomach-non) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-23*
