Quick recovery
My essential vitamin! I take it once in the morning and once before bed, and I should have started this habit long ago. I used to suffer from colds lasting a month, but after taking Ester-C, I felt better within just three days. I will surely buy it again; it is the best Vitamin C on the market!

Effective for colds.
Compares to more expensive brands. I've been using this product for years, and its quality remains consistent. It works as well as pricier brands and can knock a cold out in two days. I take it alongside 1000 IU of vitamin E and 50 mg of zinc. It's a non-acidic formula that doesn't upset my stomach even if I have acid reflux.

No colds observed
The best formulation of Vitamin C available! It’s easily absorbed and less likely to cause gastric distress, with convenient packaging in both quantity and dosage. I take 3-5,000 mg of Ester-C daily, and despite my severe allergies and asthma, I haven’t had a cold in over 5 years. I only experienced one asthma attack in the past 10 years. This product works wonders!

Forget about colds
Ester-C capsules with Bioflavonoids are considered the best by many health experts. With the capsules, you can safely take up to 6,000 mg as recommended, and I can confidently say my experience has been a complete absence of colds since I started using them!

Shortens cold duration.
My go-to for staying healthy. Vitamin C is vital. This is gentle and does not cause acid, as stated. I'm a healthy 71-year-old and have used this product for years. I believe it keeps colds away or at least shortens their duration. I highly recommend it!
