Product Overview

  • Foundation for Longer Life
  • Vitamin C for Sensitive Stomachs
  • Dietary Supplement

Vitamin C, or ascorbic acid, is a white, crystalline, water-soluble substance found in citrus fruits. As an antioxidant, vitamin C scavenges free radicals in the body and protects tissues from oxidative stress. Vitamin C also promotes the absorption of iron, while preventing its oxidation. Vitamin C is a vital cofactor to the formation of collagen, the connective tissue that supports arterial walls, skin, bones, and teeth. A major immune-supporting activity of vitamin C is boosting glutathione levels in human lymphocytes, cells that make up about 25% of all white cells in the blood.

More vitamin C is contained in the adrenal glands than any other organ in the body and is required at higher levels during times of stress. Physical stresses on the body such as ingestion of heavy metals, cigarette smoking, immune impairment, extreme temperatures, and chronic use of certain medications such as aspirin also signal the need for increased intake of vitamin C.

Vitamin C Powder contains four buffering minerals, in addition to ascorbic acid. When mixed with water, this product produces a reduced-acid solution that is non-irritating to the stomach and intestinal lining. The minerals also make it a more pleasant-tasting and healthful drink. The substances used in this product make it effervesce for a short while when it is mixed with water.

Suggested Use

Read the entire label and follow the directions carefully prior to use.

Mix one (1) teaspoon of Buffered Vitamin C Powder into a glass of water. Wait for the fizz to stop before consuming. The minerals buffer out the normally acidic vitamin C to make a pleasant tasting drink.

Relief of Abdominal Pain & Bloating.

Posted by 4959656846219466766 on Jul 14, 2014

I have been to 5 doctors in 2 years, and no one could find out why I am constantly bloated, with sever abdominal pain. A sever Constipation. They have run every test and tried surgeries. I switched to a Homeopathic Dr. in Feb. 2014. He started me with the Stress out series. It works to stop the pain. Which was my most important goal. I looked on my own for the buffered Vitamin C, and found this. It gets rid of the pain and the bloating. The constaption is easier. Now I just have to keep taking it to see if it will get rid of all my fatigue. It taste great if you mix it with Miso drink enhancements and a little sugar. It has a sour kick. BUT It WORKS! I LOVE IT!!!!!
