Great taste
This is a delicious vitamin drink. Much easier to drink your vitamins when they taste good. The price is also reasonable, which is important since many of the vitamin drinks are overly expensive.

Sufficient-C is a keeper!
This is one of those products that is truly a keeper. I am a vitamin C person and many of my friends and peers have been recommending Sufficient-C to me. I was skeptical of the claims that it tasted like a drink that was not a dietary supplement. Wow, was I wrong! Virtually no calories and a tremendous amount of immune support packed into this baby! I'm hooked. I am upgrading to the larger 250 gram canister for my next order since I use quite a lot of it and the larger canister is even better priced. I actually am impressed with the pricing since I know what each individual nutrient costs. Comparably Sufficient-C is a much better deal, plus it doubles as a drink that you actually look forward to drinking! Hint: Great for vacations!

No stevia aftertaste
This is amazing stuff! It tastes great -no stevia aftertaste. I feel like their other one the glutenizer has a more stevia taste to it. But we can't taste it in this one. Even though we like the other one as well! I add 1-2 teaspoons of ascorbic acid to this and this helps mask the sourness of the V. C. I have bought jars of this and have given this as gifts to people! Only wish it was a bit cheaper.
