Old Favorite

I have been using a time - release Vit C for years. I rarely get colds or "flu". Plus its so good for bladder health, as it makes urine more acidic - thereby making the environment unfriendly for bacteria.

Thanks for your feedback!

I take 10,000 mg. every night and do not get the virus. If I feel like the virus is coming on, I take 10,000 mg. at bed time and next day 1,000 every hour. Feel great. It is also good for the heart

Thanks for your feedback!

Not good enough

Posted by iHerb Customer on Sep 05, 2016 | Verified Purchase

The tablets are too difficult to swallow for me and "time release" means about 3 hours which is not clear from the description.

Thanks for your feedback!

pill is a little hard to swallow so will go with a powder next time.

Thanks for your feedback!

Vit C

Posted by iHerb Customer on May 08, 2011 | Verified Purchase

Disappointed because that I bought this without noticing it had calcium as another ingredient.

Thanks for your feedback!

I take this product at night because I take medications that can't be mixed with the calcium that is in it. However it works well

Thanks for your feedback!

Good to have slow release Vit C

Posted by SHL-FiveSevenTwo on Feb 24, 2017 | Verified Purchase

I like the slow release of this so I get a more steady absorption and don't waste the product. I don't like chewables unless I have a sore throat and when I want to megadose to get over a cold I buy a bottle and eat them like candy until they're gone. This however, is my everyday vitamin c and I really think it gives me the antioxidant and immune boost I need for day to day protection. I stand by vitamin C as the natural cure all when trying to prevent colds and beefing up on them if you do happen to get one. *** For new customers of iHerb, please also visit my page for other product reviews.***

I am more than happy with this product as the tablets do not disturb my somewhat delicate stomach even when I take on an empty stomach. I had a cold and fever and after taking one tablet my temperature dropped to normal within one hour and remained normal until the next day. I was quite impressed!

Thanks for your feedback!
