Cheilosis
Cracks at the corners of the mouth and/or a patchy, smooth-looking tongue — directly caused by B vitamin deficiencies, especially B2 (riboflavin) and poor absorption of B vitamins.
Also known as: Angular stomatitis, Angular cheilitis, Geographic tongue, Cracked mouth corners
📝 At a glance
Likely root causes: Vitamin B2 (riboflavin) deficiency — directly causes the cracks at the corners of the mouth; Poor absorption of B vitamins (B3, B5, B6, B12, folic acid) — produces geographic tongue; Frequently caused by celiac-like changes in the small intestine imparing fat-soluble vitamin absorption.
First thing to try: Take vitamin B2 (riboflavin) — 500 mg daily. This specifically heals the cracked corners of the mouth.
See a doctor if: See a doctor if symptoms are severe, persistent, or worsening, or if you are unsure — natural supports are meant to complement, not replace, professional care.
🔎 Start with the cause
Lasting relief rarely comes from covering a symptom. First find what is feeding the problem, change what you can, and then help the body do what it was designed to do — heal.
Likely root causes
- VitaminA natural substance your body needs in small amounts to stay healthy, like vitamin C or D. More → B2 (riboflavin) deficiency — directly causes the cracks at the corners of the mouth
- Poor absorption of B vitamins (B3, B5, B6, B12, folic acid) — produces geographic tongue
- Frequently caused by celiac-like changes in the small intestine imparing fat-soluble vitaminA natural substance your body needs in small amounts to stay healthy, like vitamin C or D. More → absorption
- Food allergies may contribute by damaging the intestinal lining
- Low stomach acid (impaired absorption of B vitamins from food)
Change what you can
- Take vitamin B2 (riboflavin) — 500 mg daily. This specifically heals the cracked corners of the mouth.
- To address the geographic tongue and overall B vitaminA natural substance your body needs in small amounts to stay healthy, like vitamin C or D. More → absorption: take B3 (niacin/niacinamide) (200 mg), B5 (pantothenic acid) (2,000 mg), B6 (200 mg), B12 (1,000 mcg), and folic acid (5 mg) daily.
- Take zinc (30 mg daily) — zinc is required for proper taste bud function and B vitaminA natural substance your body needs in small amounts to stay healthy, like vitamin C or D. More → utilization.
- Eat a comprehensive, whole-food diet rich in B vitamins: whole grains, legumes, leafy greens, nutritional yeast, seeds.
- If symptoms persist despite supplementation, have a celiac disease test — celiac or gluten sensitivity often underlies chronic B vitaminA natural substance your body needs in small amounts to stay healthy, like vitamin C or D. More → malabsorption.

This is the safest, most direct first step, since cracked mouth corners are so often simply a sign of low vitamin B2.
How to do it ▾
Why it works: Cracks at the corners of the mouth are often a direct sign the body isn't getting enough riboflavin (vitamin B2), and restoring that nutrient supports the skin's healing.
- Add 2-3 servings daily of riboflavin-rich foods such as eggs, milk or fortified alternatives, leafy greens, and almonds.
- Include a variety of whole grains and legumes to round out overall B vitamin intake.
- Keep this up daily for several weeks, since nutritional healing of skin tissue takes time.
- If cracks don't improve within a few weeks, see a doctor to check for absorption problems.
Ongoing daily habit · Daily, with each meal
Caution: What looks like a fungal infection at the mouth corners is very often this same B2-related condition — but a sore that doesn't respond to diet changes should still be checked by a doctor. Persistent cracking despite a good diet may point to a deeper absorption problem, such as celiac disease, that needs medical evaluation.
When to get help: See a doctor if the cracks bleed heavily, show signs of spreading infection (increasing redness, warmth, pus), or don't improve after a few weeks of dietary changes.

A supportive step for cases where a patchy tongue accompanies the cracked mouth corners, suggesting broader B vitamin needs.
How to do it ▾
Why it works: When cracked lips are paired with tongue changes, poor absorption of several B vitamins together is often involved, so supporting the whole B-vitamin family — not just B2 — helps address the root cause.
- Build meals around whole grains, legumes, leafy greens, and seeds to cover the range of B vitamins.
- Add nutritional yeast to soups or dishes as a natural B vitamin source, if desired.
- Support stomach acid levels by eating slowly and chewing thoroughly, since low stomach acid can worsen B vitamin absorption.
- Keep up this pattern for at least a month, since malabsorption-related symptoms improve gradually.
Ongoing daily habit · Daily
Caution: Tongue changes that persist despite a full month of good nutrition should be evaluated by a doctor for celiac disease or other absorption problems. Food allergies can also damage the gut lining and interfere with B vitamin absorption — mention any digestive symptoms to your doctor.

A simple comfort measure to use alongside dietary changes while the skin heals.
How to do it ▾
Why it works: Saliva pooling at the mouth corners keeps the skin damp, which slows healing and invites irritation, so keeping the area dry and lightly protected supports natural repair.
- Gently pat the corners of the mouth dry after eating or drinking.
- Apply a thin layer of plain petroleum jelly or a fragrance-free lip balm to protect the cracked skin.
- Avoid licking the lips or corners of the mouth, which reintroduces moisture and slows healing.
- Continue for one to two weeks while also addressing diet.
A few seconds, several times a day · After meals and before bed
Caution: Avoid flavored or scented lip products on cracked skin, as they can sting or irritate further. If the area looks infected (increasing redness, swelling, or pus), see a doctor rather than continuing home care alone.

“Disease is an effort of nature to free the system from conditions that result from a violation of the laws of health...

🌿 Overview
Cheilosis (angular stomatitis) is a nutritional deficiency condition — not an infection, though it can look like one. The cracks at the corners of the mouth are directly caused by vitamin B2 (riboflavin) deficiency. The irregular, smooth-looking 'geographic tongue' with denuded patches indicates poor absorption of the B vitaminA natural substance your body needs in small amounts to stay healthy, like vitamin C or D. More → complex — B3, B5, B6, B12, and folic acid. The root cause is often celiac-like changes in the small intestine that impair nutrient absorption. Geographic tongue is painless and taste may or may not be affected. The treatment is simple and targeted: B vitamins.
Cheilosis refers to sore, cracked, or inflamed lips and, classically, splits at the corners of the mouth, sometimes alongside a sore, smooth tongue. It is a recognized sign of B-vitaminA natural substance your body needs in small amounts to stay healthy, like vitamin C or D. More → deficiencies (such as riboflavin, niacin, B6, and B12) and iron deficiency, though the corners of the mouth can also become cracked from moisture, yeast, or ill-fitting dentures.
Where a nutritional shortfall is involved, the natural remedy is corrective: a varied, nourishing diet rich in B vitamins and iron — whole grains, legumes, leafy greens, nuts, and seeds — often resolves it, with medical guidance for confirmed deficiencies. Keeping the corners of the mouth protected and dry, and treating any yeast overgrowth, helps the local cracking heal. Because persistent or recurrent cheilosis can signal an underlying deficiency or other condition, it is worth a medical review if it does not settle with improved nutrition and gentle care.
Common signs
- Cracks, sores, or redness at the corners of the mouth
- Possibly extending to the corners of the nose (nasolabial area)
- A patchy, irregular tongue with smooth, denuded areas — 'geographic tongue'
- Geographic tongue is not painful
- Possible mild changes in the sense of taste

🍽️ Eating to help
Food is one of the gentlest medicines — small, steady changes help most.
Favor these
- Nutritional yeast (the richest food source of B vitamins)
- Whole grains and legumes for B vitamin complex
- Dark leafy greens for folate
- Seeds and nuts for zinc and B vitamins
- Cultured foods to support gut health and B vitamin production
Go easy on
- Gluten if celiac disease is suspected
- Sugar and processed foods that deplete B vitamins
Cheilosis is a textbook nutritional deficiency condition — it tells you the body is not getting or absorbing enough B vitamins. The cure is in the nutrition.
⚖️ Good to know
- What looks like a fungal infection at the corners of the mouth is very often cheilosis — a B2 deficiency that responds to riboflavin, not antifungal treatment.
- If B vitamin supplementation doesn't resolve the cracks within a few weeks, investigate celiac disease or severe malabsorption.
- Geographic tongue that persists despite supplementation may also reflect food allergy or celiac-related intestinal damage — investigate.
