Product Overview

  • Antioxidant Protection
  • 100% Pure Buffered Vitamin C Powder
  • A Dietary Supplement
  • Vegetarian/Vegan
  • GMP Quality Assured

Vitamin C is a water soluble nutrient well known for its vital role in the immune system. Vitamin C is necessary for the production of collagen (a structural protein in connective tissue) and is therefore important for skin, bone, and joint health. Vitamin C is also needed for amino acid metabolism, hormone synthesis, and the utilization of many nutrients, such as folic acid and iron. It is also a highly effective antioxidant that can protect the body’s cell and molecules from damage by free radicals generated during normal metabolism. This product supplies Magnesium Ascorbate, a buffered form of Vitamin C that is gentler on the stomach.

Suggested Use

As a dietary supplement, take 1/4 level teaspoon daily. Consider taking these other NOW products: Citrus Bioflavonoid Caps, Pycnogenol and Alpha Lipoic Acid.

Not easy to take small doses - be mindful of vit C effects on hormones

Posted by Health-Is-Wealth on Dec 02, 2013

Suggest any woman struggling with hormonal issues avoid mega doses of vit C - it's a proven aromatase inhibitor and will therefore cause a decrease in estrogen (though obviously that can be advantageous when estrogen is too high). At higher doses it can cause a decrease in both estrogen and progesterone. I've read that amounts over approx 750mg can start to cause hormonal changes that may not be beneficial.

Too acidic

Posted by Reviewer1148576 on Dec 27, 2009

I purchased this as an alternative to calcium ascorbate, which I add to mineral water and drink. However, the mag ascorbate tasted very acidic and when tested with a ph strip tested highly acid. I had to add coral calcium to the drink. I would not purchase this again.

Misleading title - won't buy again

Posted by pickier-than-thou on Feb 23, 2010

It appears to be a quality product, but it's way too acidic - it upsets my stomach even in much lower doses. I've also noticed some weird reactions with fruit juice (it formed some grey lumps before dissolving). The product name is totally misleading, made me believe I was buying a magnesium supplement improved by vitamin C and not the opposite. They should call it buffered vitamin C or something and write magnesium ascorbate on the back label only, with tiny letters - unless this confusion really helps their sales...

great product

Posted by Reviewer1002991 on Nov 07, 2008

I love having vitamin C and magnesium together. My favorite form of non-acidic vitamin C. Powder is more cost effective than capsules/tablets and is a great way to avoid fillers. Taste is ok.

Excellent but NOW should use screw on tops.

Posted by Reviewer2874238 on Oct 25, 2008

Should be used by everyone. Excellent detoxifier. No problem when used by toddler children. Shelf live is somewhat short so use fairly quickly. Short shelf life is a GOOD sign. NOW please DO NOT change this product. I wish that NOW would use screw on tops so I could recylce the bottles for other uses.
