See the relationship between ascorbic acid and digestion in the text below. Ascorbic acid (vitamin C) is a vital nutrient that should be obtained from food sources such as citrus fruits, berries and green leafy vegetables. However, for some people, higher doses are difficult to digest. This is where the mild, non-acidic forms of the vitamin come into play. C can help.
The stomach produces hydrochloric acid as well as enzymes that digest food and protects itself against these chemicals by secreting a layer of mucus and bicarbonate as a barrier. Despite this protection, some people still show signs of stomach acidity. This is often associated with a condition known as gastroesophageal reflux disease (GORD), in which the contents of the stomach return to the highly sensitive esophagus.
Heartburn and indigestion are especially common in people who are overweight, smoke, anxious, stressed, or have a hiatal hernia (in which part of the stomach moves toward the chest). In these cases, taking acidic supplements, even a weak acid such as vitamin C – can cause burning discomfort. Some people are more sensitive to the acidity of vitamin C than others and may find that vitamin C supplements have a laxative effect. Again, this depends on the acidity of the vitamin C rather than any specific toxicity.
If you are prone to indigestion or loose intestines, “mild” non-acidic vitamin C is available that does not upset your digestive system.
For example, to produce calcium ascorbate, it combines with calcium, which greatly reduces the acidity of vitamin C and makes it softer for the stomach.
Another option is a steady secretion of vitamin C, which, as its name implies, releases ascorbic acid at a slow, steady rate over six to eight hours. Not only does this increase the amount of vitamin C in your blood for a long time, but it also reduces the amount of vitamin C in your stomach at any given time.
On the other hand, boiling vitamin C dissolves in water and produces a pleasantly flavored beverage for rapid absorption. Water also dilutes ascorbic acid to reduce the risk of indigestion.
So, if you have already experienced excess acid while taking vitamin C supplements, there are several different products for you that have a milder effect and are more beneficial for the stomach.
Excessive consumption of ascorbic acid may cause gastrointestinal symptoms.
The most common complication of high vitamin C intake is indigestion.
In general, these side effects are not caused by eating foods that contain vitamin C, but by taking vitamin supplements.
If you take more than 2000 mg at the same time, you will most likely experience gastrointestinal symptoms. Therefore, a tolerable upper limit (TUL) of 2000 mg per day has been set.
The most common gastrointestinal symptoms are excessive ascorbic acid intake, diarrhea and nausea.
Excessive consumption has also been reported to lead to acid reflux, although this has not been proven by evidence.
If you have digestive problems as a result of taking too much vitamin C, simply reduce the dose of your supplement or avoid vitamin C supplements altogether.
