Soy Coating, blah

Posted by SherryB on Aug 23, 2012

I used this product for probably 8 years and then they put a soy coating on it to make it easier to swallow. I am allergic to soy and so I became very annoyed at this move by Rainbow Light. Not the best move by a natural health company in my opinion.

Shae in Florida

This works! Glass of orange juice and take one of these pills, when you feel a cold coming on, and its gone. Sometimes one zinc and go to bed. Does not bother my stomach. Thank you!

Great C

Posted by Reviewer3095414 on Jan 21, 2010

These are a little big, but they are great. I recommend taking them with orange juice. Big pills go down better with a thicker liquid. I can take them on an empty stomach. They are very tolerable and they keep my healthy. Now that I've found a good form of C at a good price, I will keep ordering.

Easy on Stomach

I paired these vitamin c tablets with Floradix to help with my anemia during my pregnancy. It did not sour my stomach.
