I highly, highly recommend this product. I've taken mega-doses of vitamin c for decades, and have incorporated this into my arsenal for several years. These are relatively small tablets, and the tablets are manufactured in such a way that they break down quickly and easily. For this reason, and because they are non-acidic, they can be taken on an empty stomach if desired. They absorb well and never cause digestive upset. I give this particular Ester-C huge credit for my excellent health. 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.

High quality Vitamin C with great benefits

Great immunity support! The tablets are a bit large but easy to swallow. I love the clean ingredients and the fact that it stays in the system longer than standard ascorbic acid. The size of the bottle (90 tablets) is perfect for a three-month course. I’ve noticed a real improvement in my energy levels and health.

Ester-C with Citrus Bioflavonoids – great vitamin C!

I’ve been taking this Ester-C supplement regularly and really like it. It’s gentle on my stomach but still seems very effective. My immune system feels stronger, and I haven’t had as many seasonal colds. Easy to swallow and great value for the quality.

Satisfied and will buy again!

Ordered Ester-C for the first time—I needed vitamin C that wouldn’t upset my stomach. The tablets are medium-sized, no strong smell, easy to swallow and pleasant taste. I take them as directed during the off-season; subjectively I recover faster and catch a cold less often. I like the formula with citrus bioflavonoids. Overall satisfied and will buy again.

This is the only vitamin C that doesn't upset my stomach, so I can finally take it consistently without any issues. I started it during cold season, and I managed to avoid getting sick while everyone else in my house was sniffling. The tablets are easy to swallow and have a very mild, pleasant citrus taste. It's a gentle yet effective supplement that I feel really supports my immune system.

Gentle but Not Time-Release

This Ester-C with citrus bioflavonoids is a solid vitamin C supplement. I like that it’s gentle on the stomach and feels high quality. It’s not a time-release version, which for me is a small minus, so I gave it 4 stars. Still, it’s a very good vitamin C to keep at home for daily wellness and immune support.
