100% Pure Vitamin C Powder is rated 4.7 out of 5 by 88.
Rated 5 out of 5 by from When this goes on sale wow! I use quite a bit of vitamin c daily (6000mg) in divided doses (3). And from what i've learned there is no difference between the laboratory made vitamin c and the natural (they put 1% natural ingredients to make the natural claim), So I shop price on vitamin c so that I can buy the highest quality vitamin E and K supplements. This vitamin C works as well as any I have used.

Rated 4 out of 5 by from pretty sour This is a good vitamin C to mix in with drinks, smoothies and fruit juice. Just keep in mind the pucker factor.

Rated 3 out of 5 by from Love Vitamin C Have purchased this product a few times in the past and have always been very satisfied. I ordered 2 more pounds in an order a few months ago was disappointed that it was no longer a powder, as described on the container. It is the consistency of granular sugar.(NOT that of powdered sugar as it was in the past orders) Beware this is NOT a POWDER it is GRANULAR, if that is important to you decision.

Rated 5 out of 5 by from versatile product I put some of this in my vitamin drink. I also use it to keep my fruit from turning dark. I put some in water and slice fruit and let sit for a while before using. Sometime I have even left overnight. GREAT

Rated 5 out of 5 by from For Baths We never ingest this, so I can't speak from that perspective, but we use it to break down chlorine in our bathwater. It works immediately, and there is never a chlorine smell when we use this. The kids skin is so much softer and we no longer need oil in the bathwater during winter months. One little scoop per tub of water is all it takes. Lasts a long time and I am always sure to have it on hand.

Rated 3 out of 5 by from 100% C Powder Good product, but is not designed to dissolve readily. If it dissolved better, it would be a 5 overall.

Rated 5 out of 5 by from An Important Supplement I like to add a scoop of this to a glass of water each day. I started doing it a year ago and find that immune system seems to be working without failure ever since. I like having the ability to turn it into a liquid for better absorption. The comparable price is good. I do wish Swanson would make the more bio-available version of vitamin C in this powder form.

Rated 5 out of 5 by from Much overlooked vitamin I like to follow Linus Paulings recommendations for dosages of vitamin C which helps the body deal with many issues of health. I find that the crystals are easier for me to use than pill, since I take many different vitamins. I Appreciate Swanson's quality and prices, and am a long time customer.

Rated 5 out of 5 by from powdered vitamin c Good way to get your vitamin C if you don't eat a lot of fruits and vegetables that have it occurring naturally . Very very tart so be careful about getting it on your fingers and then putting your fingers in or up to your lips or in your mouth .

Rated 5 out of 5 by from easy C This an easy way to get your C. Plus it gets into your system quicker.

Rated 5 out of 5 by from Very potent... When mixed with enough Lecithin and distilled water one can make a killer vitamin C tonic!

Rated 5 out of 5 by from Best Purchase EVER! I feel AWESOME! I think my immune system has never been happier; the price is amazing; AND, even in a household of three adults, it lasts FOREVER! I got my mom, who is reluctant to use anything, and she Loves it--in smoothies, cooking, and even just shaken up into juice.
