Works every time
Everytime I feel like I’m getting sick or feeling a cold coming on, I take one of these and my symptoms are gone by next morning. This has worked EVERY single time I’ve used it for years. However it is a pretty big pill so its hard to swallow and doesn’t taste the best. But you gotta do what you gotta do. Miracle Vitamin C!!

Best OTC option to support your entire immune system
It took many years for me to finally find a immune support supplement this good! I take 1 daily. EVERY DAY! I have auto immune diseases and am disabled. Finding the right combination of OTC protects to help support my weak immune system has been difficult. This product actually works! Stomach friendly. And alrhough it is a bit large and thick. It has no taste and it oretty easy to swallow down with enough water. Best OTC option to support your entire immune system. I knkw it says “upper respiratory”. But it covers everything.

The best vitamin c
This is the best vitamin you can take for your immune system! I love it, and I’ve been using this vitamin for +15 years

It really is a different kind of Vitamin C
Tablets are a little bigger than your average 1000mg tablet of vitamin C, so just be aware this tablet size might not be for everyone. I’m 38, and even I find it a little intimidating to swallow one of these pills whole, so I can only imagine what it might feel like for someone older. Still, so long as the tablet is intact, the outer coating slimes over when wet, which makes it almost impossible to choke on.Taste wise, there is no taste issue. It does taste a little more chalky than ascrobic-based vitamin C, but I wouldn’t say it’s repulsive or odd. Just chalky (blame it on the 8% calcium content).No upset stomach issues for me, and I’m on the sensitive side. Just maybe don’t consume it on an empty stomach.For size reference, a 1000mg tablet of Ester-C is shown next to a 1000mg of a Kirkland-brand ascorbic-based vitamin C.

Highly recommended!
great choice for boosting your immune system. They’re gentle on the stomach and provide 24-hour immune support. However, the tablets are a bit large, which might be difficult for some to swallow. Overall, they’re an effective and reliable supplement.

rather large
My only beef with ester c is the size of the tablets. They are so hard to swallow, but they do avoid an upset stomach.
