Calcium Ascorbate is Vitamin C (otherwise known as ascorbic acid) in a buffered condition. Vitamin C has a natural acidity which can be a little too much to handle for those that have gastrointestinal issues. This is why there is a buffered version, in which the ascorbic acid is reacted with Calcium in order to significantly reduce the acidity of the solution. Not only does this help to reduce the acidity, but it also allows the beneficial effects of Calcium to reach your body along with those of the Vitamin C.


Serving Size & Timing

The suggested use of Calcium Ascorbate is a 300mg serving to a 1000mg serving, to be taken up to three times per day depending on intended effect. The FDA daily value for Vitamin C is about 60mg meaning that a 1000mg serving would provide about 1370% of the recommended daily value.

In a national survey it was found that about 5 to 7% of American adults are Vitamin C deficient. Those who were especially at risk included groups such as black males, smokers, and people who did not use Vitamin C supplements. It was also found that strangely, Mexican Americans had built up a resistance to being Vitamin C deficient. The minimum daily value as determined by the FDA seems to be enough to prevent one from being labeled deficient, but it is not know whether this is enough Vitamin C to keep general health levels at a high.

Taking higher amounts of Vitamin C becomes necessary when under any sort of environmental stresses or traumas, including sickness.

Calcium Ascorbate Buffered Vitamin C Side Effects

There are very few side effects reported from usage of Calcium Ascorbate, and it is nontoxic. Overuse could result in side effects that are common to overuse of most supplements that in some way stimulate the gastrointestinal process. Taking any more than the recommended 2,000mg per day could result in stomach upset, nausea, vomiting, gastric problems, flatulence, diarrhea, etc. If these side effects do occur they will usually be for a brief period and can be assuaged by lowering dosage immediately.

Taking in too much Ascorbic Acid at once could cause the body’s levels of Copper to be greatly reduced. This could pose a problem for anyone that has issues with Copper deficiency or an issue with the way Copper is stored in their body. Anyone that has problems with Copper or Iron storage should consult a medical professional before going on this supplement or any other that involves Ascorbic Acid. Pregnant women should be discouraged from going on this supplement without talking to a medical professional first, since it is possible that the excess levels of Vitamin C could cause the child to develop scurvy in utero. However, this type of condition is rare and is usually only witnessed in women who consume around three times the maximum daily dosage, or around 6,000mg per day.

Calcium Ascorbate Buffered Vitamin C Bioavailability

Calcium Ascorbate possesses a pH that is neutral making it easy in terms of bodily absorption. It is easily mixed into water or juice and can also be included with food. Drink immediately after stirring in or eat immediately after mixture.
