Calcium Ascorbate (Buffered C)

WHAT IS CALCIUM ASCORBATE? CALCIUM ascorbate is the calcium salt of ascorbic acid, one of the mineral ascorbates. It is made up of approximately 9 parts of ascorbic acid to 1 part of calcium, which makes it a pH-neutral form of vitamin C because its natural acidity has been buffered and is thus much milder on the GI system (does not cause gastrointestinal irritation). Calcium ascorbate is thus considered "stomach-friendly" and is the preferred form of vitamin C for those who have a hard time with highly acidic foods, as well as those with a sensitive stomach.

What is Calcium Ascorbate?

Calcium ascorbate is the Calcium salt of ascorbic acid, one of the mineral ascorbates. It is made up of approximately 9 parts of ascorbic acid to 1 part of calcium, which makes it a pH-neutral form of vitamin C because its natural acidity has been buffered and is thus much milder on the GI system (does not cause gastrointestinal irritation). Calcium ascorbate is thus considered "stomach-friendly" and is the preferred form of vitamin C for those who have a hard time with highly acidic foods, as well as those with a sensitive stomach. Calcium ascorbate (also frequently called Ester-C or buffered C) is thought to be better absorbed and far better utilized by the body than traditional forms of vitamin C (ascorbic acid); therefore, it multiplies the benefits of vitamin C supplementation.

Another advantage of the calcium ascorbate form of vitamin C is that it helps to absorb calcium, which then becomes bioavailable to the cells. In turn, this calcium holds onto the vitamin C, prolonging its stay inside our cells. This means that the body is able to benefit from vitamin C's powerful antioxidant properties for longer.

Benefits of CALCIUM ASCORBATE

  • pH Neutral Vitamin C

  • Ideal for Sensitive Stomachs

  • Increased Absorption & Utilization

Who Needs Calcium Ascorbate?

Vitamin C may be recommended to improve immune function, to help repair damaged tissues (especially post-injury, surgery, convalescence), to stimulate post-exercise recovery, promote bone, teeth, and skin health, as well as to reduce your risk of chronic disease. A quality vitamin C supplement may also be recommended to you during times of stress to help support the fight or flight response, as well as to support the body’s natural detoxification processes. The calcium ascorbate form of vitamin c may be suggested if you have a sensitive stomach, are prone to indigestion, or have bowel looseness.

Calcium Ascorbate - Potency & Formats

Calcium ascorbate may be purchased in capsules, liquid, powder, and dissolvable crystals, typically in 500 to 1000 mg potencies. The recommended dosing varies according to the health condition but is usually in the 500mg to 4g daily range.

Final Thoughts

Vitamin C is water-soluble vitamin – i.e. it dissolves in water. Because of this, unlike fat-soluble vitamins (A, D, E, K), it cannot be stored in the body. Instead, vitamin C, once consumed, gets transported to the tissues via body fluids, and any excess is excreted via urine. Because the body cannot store vitamin C, it’s crucial to get enough via diet and or supplementation to protect overall health and maintain optimal antioxidant protection.
