Health Benefits of Vitamin C

Exactly what is this vitamin and what can it do for your body?


By Zoey Garcia


Vitamin C is needed for the growth and repair of tissues in all your body parts. Being an essential vitamin, it cannot be produced by the human body, it should be part of your nutritional intake to maintain sufficient levels. Therefore a diet with adequate levels of vitamin C is necessary for overall health.

The equivalent of one large orange a day is enough for most adult to maintain healthy levels of vitamin C. If you already rely on a diet with plenty of fruits and vegetables, or take a multivitamin, you likely won't need any additional supplements. But if you tend to eat a diet high in processed foods or don't eat the recommended daily servings of fruits and vegetables you are at risk of developing vitamin C deficiency.

Signs of a Vitamin C Deficiency

There are 7 major symptoms of Vitamin C deficiency:

Feeling Tired or Lethargic

One of the first signs of a lack of vitamin C in the diet is fatigue. You may be getting plenty of sleep but as the days go on you feel more and more tired each morning. Not only will 7+ hours of sleep not feel like enough, but you will also feel like normal daily activities are more taxing than they once were.

Your daily commute to work might make you want a nap or your typical workout may leave you feeling exhausted. Unfortunately this symptom is common to many different health issues making it difficult to diagnose as Vitamin C deficiency.

Experiencing Irritability or Mood Swings

Aside from feeling tired, many people also start to exhibit signs of irritability. They are more easily aggravated or annoyed and quick to anger. This has a lot to do with the first symptom of lethargy, as a tired body and mind easily leads to a lack of patience. Mood swings are also common. Jumping from feeling content to suddenly upset or even feeling sad can occur.

Unexplained Weight Loss

Vitamin C deficiency can cause weight loss, whether a lack of appetite is happening or not. Some will just not feel hungry, which exacerbates this symptom, but a vitamin C deficiency or scurvy is considered a wasting disease. This simply means that it causes the body to slowly waste away, regardless of how much someone may try to eat to compensate.

Joint Pain and Muscles Soreness

Chronic muscle soreness, joint pain, and unusual aches and pains are all characteristic of vitamin C deficiency. If this deficiency reaches severe levels and becomes scurvy, bleeding can even occur in the joints which can feel excruciatingly painful.

Dry Skin and Brittle Hair

Skin and hair can say a lot about the health of your body, so it's no surprise that these two factors are quickly affected by a lack of vitamin C. Very dry, rough skin is a common sign that there is something nutritionally wrong with your diet. Hair that becomes brittle, splits or otherwise becomes unhealthy out of the blue often happens alongside dry skin issues. While both of these problems don't always point to a vitamin C deficiency outright, as majority of vitamin or mineral deficiencies cause these problems, it can be an early warning sign if occurring alongside other symptoms.

Bruising and Poor Wound Healing

If you find random bruises on your body without remembering what happened or have noticed you've been bruising more easily, it might be because you're not getting enough vitamin C in your diet. Vitamin C deficiency or scurvy compromises skin health and the immune system overall, slowing down the body’s ability to heal itself. Aside from bruising, many people also notice when they get a scratch or cut that it takes longer to heal than normal. They may also be more prone to infection, and have trouble healing from a small infection that a healthy body could easily recover from.

Gum and Tooth Deterioration

While bad oral health is a symptom of mild to moderate vitamin C deficiency, it's when it reaches the point of being scurvy that the gums and teeth really begin to suffer. Periodontal diseases is a classic sign of a prolonged lack of vitamin C.

In fact, once the teeth begin to decay or break and the gums start to ache and bleed, it could mean an individual’s vitamin C levels are dangerously low and medical attention is paramount.

If you suspect you maybe suffering from Vitamin C deficiency based on these common symptoms, you should consult your doctor as soon as possible. Severe vitamin C deficiency is curable but it will be a long road to recovery. If you've only been noticing some tiredness, dry hair or have been feeling a little off, usually eating oranges daily and taking a vitamin C tablet will get you right as rain.

Choosing to take an extra vitamin C supplement might be a good idea if you don't always eat properly. Others purposely load up on vitamin C supplements if they are fighting a cold or illness as it will help boost the immune system.
