Product Overview


  • Dietary Supplement
  • Supports Immune System

Each tablet contains 1,000 mg of vitamin C, completely derived from five fully-reacted mineral ascorbates. Ascorbate C is a natural and better form of vitamin C than ascorbic acid because it is pH neutral, making it gentler on the digestive system. Vitamin C plays a vital role in collage formation, amino acid metabolism, hormone synthesis, and the body’s immune system.

Suggested Use

2 to 3 tablets daily; for short term, high potency use, do not exceed 8 tablets daily.

Other Ingredients

Stearic acid and modified cellulose gum.

Contains no yeast, dairy, egg, gluten, soy or wheat. Contains no sugar, starch, salt, preservatives, or artificial color, flavor or fragrance.


Note: If you are pregnant, may become pregnant, or breastfeeding, consult your health care professional before using this product.

Do not use if either tamper-evident seal is broken or missing. Keep out of the reach of children.

OK but contains Stearic acid

Posted by MarieMR on Apr 05, 2016

This is a good formula of vitamin c ascorbates and flavinoids. It is still better than not taking any vitamin C but you really take high doses of this one I feel anyway due to being more than just ascorbic acid. It is said that stearic acid suppresses T cells and well we need those working for our immune system. Anyhow will not purchase again and go back to my usual , non gmo and filler free powder. iHerb provides good customer service and fast delivery via DHL Thanks!

Amazing product!!

Posted by Reviewer2837310 on May 13, 2015

After my diagnose with cancer (over 4 years ago) I have not stopped taking Vit C daily. Such a wonderful, cheap and reliable way to keep your immune system working. Great antioxidant that nature offers in a simple, real, gentle way..It is also Ph neutral therefore does not cause acidity in our body (not the stomach acidity but rather systematic acidity which is unwanted in a healthy body). Everyone should increase their Vitamin C levels, particularly if facing a disease or in risky seasons. Up to 3-4 grams per day are safe and desirable.

I take several grams every day

Posted by alloriginal on Jun 13, 2013

I've used megadoses of vitamin c for 3 decades, and I believe passionately that I owe my good health and vitality in no small part to my regular use. Ultimate Ascorbate C is a tablet best utilized when taken on a full stomach (although a tablet at bedtime is good idea too). Because it is non-acidic it will not cause stomach upset. I believe that nutritional supplements saved my life. I've tried a lot of products, and I know what works and what doesn't. My reviews are honest, straighforward, and based on my experience. Read my other reviews to quickly learn from my three decades of research and experimentation.
