8 Common Signs That You're Deficient in Vitamins
A well-balanced and nutritious diet has many benefits.
On the other hand, a diet lacking in nutrients may cause a variety of unpleasant symptoms.
These symptoms are your body’s way of communicating potential vitamin and mineral deficiencies. Recognizing them can help you adjust your diet accordingly. This article reviews the 8 most common signs of vitamin and mineral deficiencies and how to fix them.
1. Brittle Hair and Nails
A variety of factors may cause brittle hair and nails. One of them is a lack of biotin. Biotin, also known as vitamin B7, helps the body convert food into energy. A deficiency in biotin is very rare, but when it does occur, brittle, thinning or splitting hair and nails are some of the most noticeable symptoms.
Other symptoms of biotin deficiency include chronic fatigue, muscle pain, cramps and tingling in the hands and feet.
Pregnant women, heavy smokers or drinkers and people with digestive disorders like leaky gut syndrome and Crohn’s disease are most at risk of developing a biotin deficiency. Also, the prolonged use of antibiotics and some anti-seizure medications are risk factors.
Eating raw egg whites may cause biotin deficiency as well. That’s because raw egg whites contain avidin, a protein that binds to biotin and can reduce its absorption. Foods rich in biotin include egg yolks, organ meats, fish, meat, dairy, nuts, seeds, spinach, broccoli, cauliflower, sweet potatoes, yeast, whole grains and bananas. Adults with brittle hair or nails might consider trying a supplement that provides about 30 micrograms of biotin per day.
2. Mouth Ulcers or Cracks in the Corners of the Mouth
Lesions in and around the mouth may partly be linked to an insufficient intake of certain vitamins or minerals. For instance, mouth ulcers, also commonly referred to as canker sores, are often the result of deficiencies in iron or B vitamins.
One small study notes that patients suffering from mouth ulcers appear to be twice as likely to have low iron levels.
In another small study, 28% of patients with mouth ulcers had deficiencies in thiamin (vitamin B1), riboflavin (vitamin B2) and pyridoxine (vitamin B6). Angular cheilitis, a condition that causes the corners of the mouth to crack, split or bleed, can be caused by excess salivation or dehydration. However, it may also be caused by an insufficient intake of iron and B vitamins, particularly riboflavin. Foods rich in iron include poultry, meat, fish, legumes, dark leafy greens, nuts, seeds and whole grains. Eat Vitamin C rich foods with these iron rich foods to aid in absorption.
Good sources of thiamin, riboflavin and pyridoxine include whole grains, poultry, meat, fish, eggs, dairy, organ meats, legumes, green vegetables, starchy vegetables, nuts and seeds.
If you experience these symptoms, try adding the foods above to your diet to see if your symptoms improve.
3. Bleeding Gums
Sometimes a rough tooth brushing technique is at the root of bleeding gums, but a diet lacking in vitamin C can also be to blame.
Vitamin C plays important roles in wound healing, immunity and even acts as an antioxidant, helping prevent cell damage.
The human body does not make vitamin C on its own, which means the only way to maintain adequate levels of it is through the diet and supplementation.
Vitamin C deficiencies are rare in individuals who consume enough fresh fruits and vegetables. That said, many people fail to eat enough fruits and vegetables each day. This may explain why studies performing routine screenings of healthy populations estimate low vitamin C levels in 13–30% of the population.
Consuming very little vitamin C through the diet for long periods of time can bring on symptoms of deficiency, including bleeding gums and even tooth loss. Another serious consequence of severe vitamin C deficiency is scurvy, which depresses the immune system, weakens muscles and bones and makes people feel fatigued and lethargic.
Other common signs of vitamin C deficiency include easy bruising, slow wound healing, dry scaly skin and frequent nosebleeds. Make sure to consume sufficient amounts of vitamin C by eating at least 2 pieces of fruit and 3–4 portions of vegetables each day. Try citrus, strawberries, cauliflower, kiwi and exotic fruit and fruit powders like camu, acerola and amla.
4. Poor Night Vision and White Growths on the Eyes
A nutrient-poor diet can sometimes cause vision problems.
For instance, low intakes of vitamin A are often linked to a condition known as night blindness, which reduces people’s ability to see in low light or darkness. That’s because vitamin A is necessary to produce rhodopsin, a pigment found in the retinas of the eyes that helps you see at night.
When left untreated, night blindness can progress to xerophthalmia, a condition that can damage the cornea and ultimately lead to blindness.
Another early symptom of xerophthalmia is Bitot’s spots, which are slightly elevated, foamy, white growths that occur on the conjunctiva or white part of the eyes. The growths can be removed to a certain extent but only fully disappear once the vitamin A deficiency is treated.
Luckily, vitamin A deficiency is rare in developed countries. Those who suspect their vitamin A intake to be insufficient can try eating more vitamin A-rich foods, such as organ meats, dairy, eggs, fish, dark leafy greens and yellow-orange colored vegetables. Cod liver oil is the best source for supplementation. Don’t forget about the other fat soluble vitamins, D3, K2 and Vitamin E.
5. Scaly Patches and Dandruff
Seborrheic dermatitis (SB) and dandruff are part of the same group of skin disorders that affects the oil-producing areas of your body.
Both involve itchy, flaking skin. Dandruff is mostly restricted to the scalp, whereas seborrheic dermatitis can also appear on the face, upper chest, armpits and groin. The likelihood of these skin disorders is highest within the first three months of life, during puberty and in mid-adulthood.
Dandruff and seborrheic dermatitis may be caused by many factors, with a nutrient poor diet being one of them. For instance, low blood levels of zinc, niacin (vitamin B3), riboflavin (vitamin B2) and pyridoxine (vitamin B6) may each play a role. Foods rich in niacin, riboflavin and pyridoxine include whole grains, poultry, meat, fish, eggs, dairy, organ meats, legumes, green vegetables, starchy vegetables, nuts and seeds. Seafood, meat, legumes, dairy, nuts and pumpkin seeds are all good sources of zinc.
6. Hair Loss
Hair loss is a very common symptom. In fact, up to 50% of men and women report suffering from hair loss by the time they reach 50 years of age.
A diet rich in the following nutrients may help prevent or slow down hair loss.
• Iron: This mineral is involved in the making of DNA, including the DNA present in hair follicles. Too little iron can cause hair to stop growing or fall out.
• Zinc: This mineral is essential for protein synthesis and cell division, two processes needed for hair growth. As such, hair loss may develop from a zinc deficiency.
• Linoleic acid (LA) and alpha-linolenic acid (ALA): These essential fatty acids are required for hair growth and maintenance.
• Niacin (vitamin B3): This vitamin is necessary for keeping hair healthy. Alopecia, a condition in which hair falls out in small patches, is one possible symptom of niacin deficiency.
• Biotin (vitamin B7): Biotin is another B vitamin that, when deficient, may be linked to hair loss.
Meat, fish, eggs, legumes, dark leafy greens, nuts, seeds and whole grains are good sources of iron and zinc.
Niacin-rich foods include meat, fish, dairy, whole grains, legumes, nuts, seeds and leafy greens. These foods are also rich in biotin, which is also found in egg yolks and organ meat.
Leafy vegetables, nuts and whole grains are rich in LA, while walnuts, flaxseeds, chia seeds and soy nuts are rich in ALA. These nutrients appear to boost hair growth and reduce hair loss in people with documented deficiencies.
7. Red or White Bumps on Skin
Some people suffer from keratosis pilaris, a condition that causes goosebump like bumps to appear on the cheeks, arms, thighs or buttocks. These little bumps may also be accompanied by corkscrew or ingrown hairs.
Keratosis pilaris often appears in childhood and naturally disappears in adulthood. It has been observed in people with diets low in vitamins A and C. People with this condition may consider adding foods rich in vitamins A and C to their diet. These include organ meats, dairy, eggs, fish, dark leafy greens, yellow-orange colored vegetables and fruit.
8. Restless Leg Syndrome
Restless leg syndrome (RLS), also known as Willis-Ekbom disease, is a nerve condition that causes unpleasant or uncomfortable sensations in the legs, as well as an irresistible urge to move them.
There appears to be a link between symptoms of RLS and a person’s blood iron levels. For instance, several studies link low blood iron stores to an increased severity of RLS symptoms. Several studies also note that symptoms often appear during pregnancy, a time in which women’s iron levels tend to drop.
Supplementing with iron generally helps decrease RLS symptoms, especially in people with a diagnosed iron deficiency. However, effects of supplementation may vary from person to person.
Since higher iron intakes appear to reduce symptoms, increasing the intake of iron-rich foods, such as meat, poultry, fish, legumes, dark leafy greens, nuts, seeds and whole grains, may also be beneficial. It may be especially handy to combine these iron-rich foods with vitamin C-rich fruits and vegetables, as these can help increase iron absorption.
Unnecessary supplementation of iron can do more harm than good and may reduce the absorption of other nutrients. Extremely high iron levels can even be fatal in some cases, so it’s best to always consult your healthcare professional before taking supplements. Vitamin B12 deficiency has also been linked to RLS and supplementation can be safe and effective.
It is always a good idea to be tested for nutrient status before supplementing with isolated nutrients. Ask about the best and most accurate testing.
