I bought for my kitty

my cat who is a senior has a cat virus that seems to stay in his body & flares up often where he sneezes coughs & has nasal congestion this vitamin c powder with calcium keeps the symptoms at a minimum it might work even better if I used more than 1/16 th of a teaspoon per day(mixed in a lickable cat treat) but I don't want to risk him getting kidney stones. lifesource vitamins is a very safe company to buy supplements from.

Wasteful packaging and no taste

I was excited to purchase and receive this product knowing sales benefit Christian charities, but was disappointed in the product itself. The bottle it comes in is very wasteful, in my opinion, and is only about half full. Other companies I have ordered from do the same and I am not sure why they cannot find an appropriate-sized container for the 8.8 oz. or fill it with more product and charge an appropriate price for the increase in product. This is also tasteless, which was another disappointment. I like the tart taste of the Quali-C vitamin C powder I have purchased in the past so will go back to buying that. This one does dissolve in water but requires vigorous shaking whereas the Quali-C does not. It dissolves the second it hits the water. On the plus side, ordering from the website was easy, customer service is responsive, and shipping was fast. But, all in all, I will not purchase this product again.

I really like these because, if I'm not feeling well, I don't like taking multiple capsules of Vitamin C. With the crystals, I can make a hot drink and add them in. We also use a small amount in the dog's meals.
