What is vitamin C?
Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that the body cannot produce itself.
This means that we need to get it through our diet - or as a supplement if the need is not met. Vitamin C is mainly found in fruits and vegetables such as oranges, peppers, broccoli and strawberries.
An important antioxidant
Vitamin C acts as an antioxidant, which means it protects the body's cells from free radical damage. It can help prevent disease and promote healthy aging.
The immune system gets a boost
You've probably heard that vitamin C boosts the immune system - and there's some truth to that.
Vitamin C helps support both the innate and acquired immune system. It helps white blood cells function effectively and fight infections. For colds and flu, many people choose to take extra vitamin C because it can slightly shorten the course of the illness.
Vitamin C and wound healing
Vitamin C also plays an important role in the formation of collagen - a protein necessary for skin, tendons, blood vessels and bones.
That's why vitamin C is important for the body to heal after wounds or surgery. If you don't have enough vitamin C, wound healing can take longer and the skin can become more vulnerable.
Better absorption of iron
Did you know that vitamin C improves the body's absorption of dietary iron?
Especially the iron found in plants (non-heme iron) is difficult to absorb, but with vitamin C it becomes easier. This means that if you eat a very plant-based diet, a glass of orange juice with your meal can make a big difference.
Preventing deficiency symptoms
Vitamin C deficiency can lead to fatigue, weakened immune systems and, in rare cases, scurvy - a serious deficiency condition.
At Doctors Denmark, we mainly see patients with mild deficiency symptoms such as fatigue and frequent infections. These symptoms can often be improved with dietary changes or supplementation if necessary.
How much vitamin C do you need?
The official recommendations for adults are around 75 mg daily.
Most people get their needs covered through a varied diet, but in cases of stress, smoking or illness, the need may be higher. It's always a good idea to talk to a doctor if you're unsure about your needs.
Can you have too much?
Vitamin C is water-soluble, so the body excretes the excess in the urine. However, large doses - for example over 1000 mg daily - can cause side effects such as stomach upset and diarrhea.
If you are taking supplements, follow the recommendations and talk to your doctor if you experience any side effects or uncertainty.
Signs of vitamin C deficiency
Severe deficiency is rare in the UK, but some people may have low levels without realizing it. Symptoms include fatigue, weakened immune system, slow wound healing and dry skin.
Long-term deficiency can lead to scurvy - a condition where the body cannot produce enough collagen. This is manifested by bleeding gums and weakness in muscles and bones.
When should you see a doctor?
If you experience prolonged fatigue, frequent infections or poor wound healing, it could be a sign of vitamin C deficiency.
At Doctors Denmark, we can help you find the cause. We can take blood tests, assess your diet and recommend supplements if necessary. You decide when it's convenient for you to come by.
