I like Calcium Ascorbate very much. I am using it every night before bedtime and during the day when I feel under weather:-) It's very easy on stomach and it is very powefull for immune system.

non offensive taste

This is the form of Vitamin C that I am able to add to my cats' raw food diet since it is not sour. I have two males, one of which has had Struvite crystals which he had surgery for. I add a pinch of Calcium Ascorbate to their food to help keep their urinary pH down.

► All is Good BUT This is NOT a Non-GMO Vitamin C Product !

Posted by 3827GreenWood on Nov 29, 2013

This Calcium Ascorbate product offered by Now Foods combines Ascorbic Acid (Vitamin C) with Calcium Carbonate. Calcium Ascorbate is a form of Vitamin C which is much more readily absorbed in the blood stream than the other forms of calcium. Importantly, Calcium is coupled with Vitamin C to deliver the benefits of both Calcium & Vitamin C. All is good with this Vitamin C product 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 7 to 7.5, it's pH neutral, very gentle to stomach and basically almost tasteless when mixed in water with no sweetener/flavouring ingredient added. This product is suitable for those who are sensitive to strong acidic or have gastric irritation. However, 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!

Great antihistamine

Posted by Reviewer2575097 on Oct 23, 2013

I appear to suffer from a condition called "Histadelia" - too much histamine in the body, which not just makes you way more susceptible to allergies, it also makes you more likely to suffer from anxiety and depression. Whether you believe Histadelia is a real illness or not, I do know that I have way more histamine than usual floating around my body. I sprayed some deodorant on, which always makes me very wheezy. I then took about 1/2 teaspoon of this powder, and within 20 minutes my airways were completely clear. It worked just as well as my Ventolin inhaler that I take for asthma! I have been taking 1/2 teaspoon three times a day for the last week and my mood is starting to get a bit brighter. Vitamin C destroys histamine while calcium is supposed to release it from the cells, so together it is a great natural way to remove histamine from the body, instead of just blocking the symptoms of it, which is all antihistamine tablets do. One thing I have noticed is that about 2 hours after I take it, I get a histamine reaction (feeling itchy in my body) but as far as I know this is a temporary thing as all the histamine is being released out of your cells. I will update in a few weeks/months.
