All is good with this Vitamin C product offered by Now Foods, except it is NOT a Non-GMO product. It means, this is a Genetically Modified Organism (GMO) product. If you take a Vitamin C supplement with Ascorbic Acid and you guessed it, you are likely consuming a supplement with GMO origins, unless the corn was certified organic. The main source for Ascorbic Acid or Vitamin C is corn which extensively corrupt material made by Monsanto and others. In fact, 98% of corn crops are GMO tainted. Regarding the taste, with the pH level in the range of 2.5 to 3, it's in the range of strong Acidic level and one can definitely expect a strong sour taste on this product as no sweetener/flavouring ingredient is added. Alkaline tastes a bit bitter in general. If you are looking for something Non-GMO Vitamin C product, this will not suit you. I am a strong advocate on scientific medical research and evidence-based information, and constantly want to differentiate between marketing hyperbole and real world effects. I hope you'll find my review Helpful to you. Best wishes and good health to everyone!

I really can´t separate the effects that this product gives me because I also take two kinds of multivitamins at the same time. I have more energy and my overall wellbeing is a little better. I usually take vitamin C before workouts to boost my energy and mental strenght. A good product, but necessary only if one feels a little ill or low on energy.

효과가 좋아서 재구매했는데 재구매하고 확인하니 중국산이고 패킹만 미국이네요. 역플라시보인지 모르겠는데 괜히 찜찜하네요. 신거 좋아해서 먹는데는 수월합니다.

bought it to make my own v c toner but it somehow makes the toner very sticky, not as good as I expected so possibly won't order again.

I bought the ascorbic acid powder because it absorbs easier then a pill form & since I have candida my digestion is not up to par. Makes your water rather sweet tasting but I rinse my mouth with plain water afterwards.

Couldn't take it in pure water, but works well in mixed juices. I prefer pills.

it is really sour. I add it to my powder MSM and collagen, taken in early morning. I haven't had bad reaction though as I always take it with empty stomach. Nah, I don't have any stomach acid issue to begin with. update: now i use this for my topical DIY vitamin c serum! Love it

These crystals really don't taste so good, OK disguised with another flavor but still take some getting down!

I haven't used the crystal long enough, but I've used them once a facial mask that I put together of honey, coconut oil and the crystals...nice results....
