iHerb Customer Reviews
Nice product, very bad shipping service with DHL
I live in Montreal, Canada and I requested this product via online. I tasted the Ascorbic Acid and I founded very good. However, I would like to advise iHerb to reconsider send their products to clients using DHL because I had a very bad experience. That is, after 6 businesses days waiting for the product, I received a call from DHL (Dorval Montreal) that they could not delivered my product because my apartment's doorbell was not working. I said them, why you did not give a call, and they answered me (in a rude way) "We dont call nobody". So, DHL told me that I must to pick up my product in a place in a so far way place (called Loomier Express) almost at the East end of the Montreal Island (1h 7m public transp from where I live), and the product will be there only for 4 days!. So, I went there, and I after waiting 10 minutes for a person to show off at the counter, a lady told me she needs a number, so I gave her the iHerb order number with my ID, and she rudely answered me "that's not the number"! I said, well, DHL Dorval do not gave me any number and she said to me very rude "that's not her problem". So, I had to call from my cellphone (because she didnt even offer me her office phone) to call my friend (located in another Canadian province) to check online the Montreal DHL phone number in order to be able to call then and ask for that DHL number. After, several tries, I finally got the number, gave it to the rude lady and got my product, which by surprise I had to pay $19.39 Canadian dollars for custom, which by the way I was not previously advised by iHerb about this charges when I purchased the product online. Resuming: I never and ever I am going to request any product that uses DHL as a Currier. I had never experienced in my life such kind of awful treatment!

Dissolves well, pharmaceutical grade, excellent!

Posted by Reviewer1287175 on Jul 01, 2016

This is my favorite Ascorbic Acid crystals. No, it's not made in Scotland like Dr's Best, but it's pharmaceutical grade so no worries about impurities. And it's much more economical. It dissolves easily in water, and I add a little stevia and just enjoy.

Great Need for Vitamin C

Posted by 5256438823273658091 on May 20, 2016

Due to recent information I had come across about the importance of using Vitamin C as an antioxidant caused me to continue searching for ways to incorporate it into my routine. Due to the great quantity needed daily in our systems I knew that pills weren't the total answer. At a health conference a few years ago, it was mentioned to take 10,000 units (10 pills) sustained release coated C in case of colds or flu and to take them every four hours. Shortly after that I came down with a bad cold and decided to give it a try. I took 10 every four hours four times throughout the two day weekend. By Monday I was able to be at work, whereas many co-workers had missed several days due to this particular strand of cold (??) that year. Since then I've told others (and seen it work with them) and I have kept a bottle on hand for that. After the recent information received at an online seminar and finding out about the powder form, I decided to give it a try. With my investigation, I think this is the best brand for my family. My husband and I both put a level tablespoon in a 20 oz. container of water, tea or juice and drink throughout the day. We add more of the C throughout the day. (I also learned that if you got too much, you'd have diahreah. That hasn't happened to us yet.) I don't know of specific results from the powder yet, but we have neither been sick with colds or flu symptoms in several years (although we haven't been on the powder form any length of time, so most of our results have come from the tablets, but as everyone realizes, you can only take so many tablets!)
