E302 Calcium ascorbate

What is E302 or Calcium ascorbate?

E302, or calcium ascorbate, is a calcium salt of ascorbic acid used as an antioxidant and acidity regulator. It's commonly found in dietary supplements and fortified foods, as it combines the benefits of vitamin C with calcium for added nutritional value.


Why do I have an intolerance?

People with an intolerance to calcium ascorbate may react either to the ascorbic acid component or the added calcium. This could lead to digestive issues, such as bloating or cramps, or in some cases, skin irritation. Overloading the system with excess calcium may also trigger an imbalance, leading to discomfort.


What can I do about it?

To manage intolerance, limit your consumption of foods and supplements containing calcium ascorbate. Opt for natural sources of vitamin C and calcium, such as leafy greens or citrus fruits, in more moderate amounts. Checking food labels can also help avoid products containing this additive.
