Vitamin C, the immune booster

Especially now in autumn, the water-soluble vitamin is back in fashion because it strengthens the immune system. And in the current Corona times, it is even more in demand. Vitamin C also protects and supports the skin. But not everyone can take it. Have you ever heard of a vitamin C allergy or intolerance? Neither do I until I got it. To be more precise, I reacted extremely badly to ascorbic acid, as vitamin C is also called. It started with the fact that every time I took pain pills that combined acetylsalicylic acid (ASA) with ascorbic acid, I got thick puffiness under my eyes. If I ate too many foods containing vitamin C, I felt sick and the toilet became my best friend. Often times I wasn’t even aware of an overdose. Because vitamin C is not only found in fruits and fresh vegetables, where one suspects it. It is also used as an additive in many products, such as sausages and meat products, to make them more durable and prevent discoloration. Because ascorbic acid reduces the formation of free radicals, which can arise from the oxygen in the air. So it’s a natural antioxidant. Unfortunately, I didn’t succeed much better with vitamin C in cosmetics either. Instead of glow and long-lasting moisture, redness and pustular appearances adorned my face. And what does the dermatologist say? Dr. Hans Peter Schoppelrey, dermatologist and allergist at the „Haut- und Laser Zentrum“ in Munich, promptly provided me with confirmation that one can actually be allergic to vitamin C. “It’s true,” he says. “But for the medical professionals it was rather a surprising finding that some people develop intolerance and even allergies to vitamin C taken orally. However, many products today contain industrially produced, high-dose vitamin C. In the event of an overdose, the vitamin is excreted in the urine because it is water-soluble, but some of it can be stored on the passage through the intestine.“ And because vitamin C also travels through the kidneys, problems with an overdose can occur, especially in people with underactive kidneys. Oxalic acid is then increasingly formed in the kidneys, which promotes the formation of kidney stones. And how does an allergic reaction manifest itself? “With bitches on the tongue, gas and diarrhea,” explains Schoppelrey. “Perioral dermatitis can occur around the mouth.“ How can you tell when it is better to avoid cosmetics containing vitamin C? Schoppelrey: “Vitamin C on the skin can cause two reactions.… weiterlesen
