8 Common Signs You're Deficient in Vitamins
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 address 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 occurs, 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 Crohn's disease are at the greatest risk of developing biotin deficiency.
Also, the prolonged use of antibiotics and some anti-seizure medications is a risk factor.
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.
However, only a few small studies and case reports have observed the benefits of supplementing with biotin, so a biotin-rich diet may be the best choice.
Biotin is a B vitamin involved in many body functions. It plays an important role in strengthening hair and nails. A deficiency in this vitamin is generally rare but may occur in certain cases.
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 with mouth ulcers appear to be twice as likely to have low iron levels.
In another small study, around 28% of patients with mouth ulcers had deficiencies in thiamine (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.
Good sources of thiamine, 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.
People with mouth ulcers or cracks at the corners of the mouth may want to try consuming more foods rich in thiamine, riboflavin, pyridoxine, and iron to alleviate symptoms.
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 an important role in wound healing and immunity, and it even acts as an antioxidant, helping prevent cell damage.
Your body does not make vitamin C on its own, so the only way to maintain adequate levels of it is through diet.
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.
Consuming very little vitamin C through the diet for long periods can bring on symptoms of deficiency, including bleeding gums and even tooth loss.
Other common signs of vitamin C deficiency include easy bruising, slow wound healing, dry scaly skin, and frequent nosebleeds.
Make sure to consume enough vitamin C by eating at least 2 pieces of fruit and 3–4 portions of vegetables each day.
People who eat few fresh fruits and vegetables may develop vitamin C deficiency. This can lead to unpleasant symptoms like bleeding gums, a weakened immune system, and, in severe cases, tooth loss and scurvy.
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.
Fortunately, vitamin A deficiency is rare in developed countries. Those who suspect their vitamin A intake is insufficient can try eating more vitamin-A-rich foods, such as organ meats, dairy, eggs, fish, dark leafy greens, and yellow-orange colored vegetables.
Unless diagnosed with a deficiency, most people should avoid taking vitamin A supplements. That's because vitamin A is a fat-soluble vitamin, which, when consumed in excess, can accumulate in the body's fat stores and become toxic.
Symptoms of vitamin A toxicity can be serious and include nausea, headaches, skin irritation, joint and bone pain, and, in severe cases, even coma or death.
Low vitamin A intake may cause poor night vision or growths on the white part of the eyes. Adding more vitamin-A-rich foods to your diet can help you avoid or reduce these symptoms.
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 3 months of life, during puberty, and in mid-adulthood.
Studies show that both conditions are also very common. Up to 42% of infants and 50% of adults may suffer from dandruff or seborrheic dermatitis at one point or another.
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.
While the link between a nutrient-poor diet and these skin conditions is not fully understood, people with dandruff or seborrheic dermatitis might want to consume more of these nutrients.
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.
Stubborn dandruff and scaly patches on the scalp, eyebrows, ears, eyelids, and chest may be caused by low intake of zinc, niacin, riboflavin, and pyridoxine. Adding these nutrients to the diet may help reduce symptoms.
6. Hair Loss
Hair loss is a very common symptom. In fact, up to 50% of adults report hair loss by the time they reach 50 years of age.
A diet rich in the following nutrients may help prevent or slow hair loss.
- Iron. This mineral is involved in DNA synthesis, including that of 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, zinc deficiency may cause hair loss.
- 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, whole grains, and vegetable oils are rich in LA, while walnuts, flaxseeds, chia seeds, and soy nuts are rich in ALA.
Many supplements claim to prevent hair loss. Many of them contain a combination of the nutrients above, in addition to several others.
These supplements appear to boost hair growth and reduce hair loss in people with documented deficiencies in the aforementioned nutrients. However, there is very limited research on the benefits of such supplements in the absence of a deficiency.
It's also worth noting that taking vitamin and mineral supplements in the absence of a deficiency may worsen hair loss, rather than help it.
For instance, excess selenium and vitamin A, two nutrients often added to hair growth supplements, have both been linked to hair loss.
Unless your healthcare provider confirms a deficiency, it's best to opt for diets rich in these nutrients, rather than supplements.
The vitamins and minerals mentioned above are needed for hair growth, so diets rich in them may help prevent hair loss. However, the use of supplements — except in cases of deficiency — may cause more harm than good.
7. Red or White Bumps on the Skin
Keratosis pilaris is 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.
The condition often appears in childhood and naturally disappears in adulthood.
The cause of these little bumps is still not fully understood, but they may appear when too much keratin is produced in hair follicles. This produces red or white elevated bumps on the skin.
Keratosis pilaris may have a genetic component, meaning that a person is more likely to have it if a family member has it. That said, it has also been observed in people with diets low in vitamins A and C.
Thus, in addition to traditional treatments with medicated creams, 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.
Inadequate intake of vitamins A and C may be linked to keratosis pilaris, a condition that leads to the appearance of red or white bumps on the skin.
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.
According to the National Institute of Neurological Disorders and Stroke, RLS affects up to 10% of Americans, with women twice as likely to experience the condition. For most people, the urge to move seems to intensify when they're relaxing or trying to sleep.
While the exact causes of RLS are not fully understood, 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 during 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, the 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.
Using cast-iron pots and pans and avoiding tea or coffee at meals can also help boost iron absorption.
Nevertheless, it's worth noting that unnecessary supplementation 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 consult your healthcare provider before taking supplements.
Finally, some evidence suggests that magnesium insufficiency may play a role in restless leg syndrome.
Restless leg syndrome is often linked to low iron levels. Those with this condition may want to increase their intake of iron-rich foods and discuss supplementation with their healthcare provider.
The Bottom Line
A diet that provides an insufficient intake of vitamins and minerals can cause several symptoms, some of which are more common than others.
Often, increasing your intake of foods rich in the appropriate vitamins and minerals can help resolve or greatly reduce your symptoms.

1. Stay Informed<p>A first order of business in pet evacuation planning is to understand and be ready for the possible threats in your area. Visit <a href="https://www.ready.gov/be-informed" target="_blank">Ready.gov</a> to learn more about preparing for potential disasters such as floods, hurricanes, and wildfires. Then pay attention to related updates by tuning <a href="http://www.weather.gov/nwr/" target="_blank">NOAA Weather Radio</a> to your local emergency station or using the <a href="https://www.fema.gov/mobile-app" target="_blank">FEMA app</a> to get National Weather Service alerts.</p>
2. Ensure Your Pet is Easily Identifiable<p><span>Household pets, including indoor cats, should wear collars with ID tags that have your mobile phone number. </span><a href="https://www.avma.org/microchipping-animals-faq" target="_blank" rel="noopener noreferrer">Microchipping</a><span> your pets will also improve your chances of reunion should you become separated. Be sure to add an emergency contact for friends or relatives outside your immediate area.</span></p><p>Additionally, use <a href="https://secure.aspca.org/take-action/order-your-pet-safety-pack" target="_blank" rel="noopener noreferrer">'animals inside' door/window stickers</a> to show rescue workers how many pets live there. (If you evacuate with your pets, quickly write "Evacuated" on the sticker so first responders don't waste time searching for them.)</p>
3. Make a Pet Evacuation Plan<p> "No family disaster plan is complete without including your pets and all of your animals," says veterinarian Heather Case in <a href="https://www.youtube.com/watch?v=Q9NRJkFKAm4" target="_blank">a video</a> produced by the American Veterinary Medical Association.</p><p>It's important to determine where to take your pet in the event of an emergency.</p><p>Red Cross shelters and many other emergency shelters allow only service animals. Ask your vet, local animal shelters, and emergency management officials for information on local and regional animal sheltering options.</p><p>For those with access to the rare shelter that allows pets, CDC offers <a href="https://www.cdc.gov/healthypets/emergencies/pets-in-evacuation-centers.html" target="_blank">tips on what to expect</a> there, including potential health risks and hygiene best practices.</p><p>Beyond that, talk with family or friends outside the evacuation area about potentially hosting you and/or your pet if you're comfortable doing so. Search for pet-friendly hotel or boarding options along key evacuation routes.</p><p>If you have exotic pets or a mix of large and small animals, you may need to identify multiple locations to shelter them.</p><p>For other household pets like hamsters, snakes, and fish, the SPCA recommends that if they normally live in a cage, they should be transported in that cage. If the enclosure is too big to transport, however, transfer them to a smaller container temporarily. (More on that <a href="https://www.spcai.org/take-action/emergency-preparedness/evacuation-how-to-be-pet-prepared" target="_blank" rel="noopener noreferrer">here</a>.)</p><p>For any pet, a key step is to establish who in your household will be the point person for gathering up pets and bringing their supplies. Keep in mind that you may not be home when disaster strikes, so come up with a Plan B. For example, you might form a buddy system with neighbors with pets, or coordinate with a trusted pet sitter.</p>
4. Prepare a Pet Evacuation Kit<p>Like the emergency preparedness kit you'd prepare for humans, assemble basic survival items for your pets in a sturdy, easy-to-grab container. Items should include:</p><ul><li>Water, food, and medicine to last a week or two;</li><li>Water, food bowls, and a can opener if packing wet food;</li><li>Litter supplies for cats (a shoebox lined with a plastic bag and litter may work);</li><li>Leashes, harnesses, or vehicle restraints if applicable;</li><li>A <a href="https://www.avma.org/resources/pet-owners/emergencycare/pet-first-aid-supplies-checklist" target="_blank">pet first aid kit</a>;</li><li>A sturdy carrier or crate for each cat or dog. In addition to easing transport, these may serve as your pet's most familiar or safe space in an unfamiliar environment;</li><li>A favorite toy and/or blanket;</li><li>If your pet is prone to anxiety or stress, the American Kennel Club suggests adding <a href="https://www.akc.org/expert-advice/home-living/create-emergency-evacuation-plan-dog/" target="_blank" rel="noopener noreferrer">stress-relieving items</a> like an anxiety vest or calming sprays.</li></ul><p>In the not-unlikely event that you and your pet have to shelter in different places, your kit should also include:</p><ul><li>Detailed information including contact information for you, your vet, and other emergency contacts;</li><li>A list with phone numbers and addresses of potential destinations, including pet-friendly hotels and emergency boarding facilities near your planned evacuation routes, plus friends or relatives in other areas who might be willing to host you or your pet;</li><li>Medical information including vaccine records and a current rabies vaccination tag;</li><li>Feeding notes including portions and sizes in case you need to leave your pet in someone else's care;</li><li>A photo of you and your pet for identification purposes.</li></ul>
5. Be Ready to Evacuate at Any Time<p>It's always wise to be prepared, but stay especially vigilant in high-risk periods during fire or hurricane season. Practice evacuating at different times of day. Make sure your grab-and-go kit is up to date and in a convenient location, and keep leashes and carriers by the exit door. You might even stow a thick pillowcase under your bed for middle-of-the-night, dash-out emergencies when you don't have time to coax an anxious pet into a carrier. If forecasters warn of potential wildfire, a hurricane, or other dangerous conditions, bring outdoor pets inside so you can keep a close eye on them.</p><p>As with any emergency, the key is to be prepared. As the American Kennel Club points out, "If you panic, it will agitate your dog. Therefore, <a href="https://www.akc.org/expert-advice/home-living/create-emergency-evacuation-plan-dog/" target="_blank" rel="noopener noreferrer">pet disaster preparedness</a> will not only reduce your anxiety but will help reduce your pet's anxiety too."</p>
Evacuating Horses and Other Farm Animals<p>The same basic principles apply for evacuating horses and most other livestock. Provide each with some form of identification. Ensure that adequate food, water, and medicine are available. And develop a clear plan on where to go and how to get there.</p><p>Sheltering and transporting farm animals requires careful coordination, from identifying potential shelter space at fairgrounds, racetracks, or pastures, to ensuring enough space is available in vehicles and trailers – not to mention handlers and drivers on hand to support the effort.</p><p>For most farm animals, the Red Cross advises that you consider precautionary evacuation when a threat seems imminent but evacuation orders haven't yet been announced. The American Veterinary Medical Association has <a href="https://www.avma.org/resources/pet-owners/emergencycare/large-animals-and-livestock-disasters" target="_blank">more information</a>.</p>
Bottom Line: If You Need to Evacuate, So Do Your Pets<p>As the Humane Society warns, pets left behind in a disaster can easily be injured, lost, or killed. Plan ahead to make sure you can safely evacuate your entire household – furry members included.</p>
