Yes, a severe vitamin C deficiency can cause body odor, specifically a putrid-smelling sweat, as part of the condition known as scurvy, which also impairs the body's ability to break down certain substances, affecting sweat odor. Deficiencies in vitamin C, and zinc, can disrupt the body's microbial balance, leading to unusual body odor, but it's important to see a doctor to rule out underlying issues.
Vitamin D: The Secret to Staying Fresh
Vitamin D does more than just give you a sunny glow—it's also super important for keeping your skin and body in check. If you're low on it, your skin could let more bacteria do their thing, which = more body odor.
To date, no scientific data show that vitamin C has a deodorizing effect or that it could attenuate unpleasant body odors. As a reminder, deodorants act on two mechanisms: reducing bacterial proliferation and neutralizing odor molecules produced during sweat breakdown.
Putrid-smelling sweat is a symptom of scurvy, according to a frequently cited review published in The Journal of Biochemistry. Sources of vitamin C include plant foods like citrus fruits, potatoes, tomatoes, and spinach, according to Mayo Clinic.
While gradual changes in body odor are typically normal, sudden or intense shifts may indicate an underlying health issue. Conditions like diabetes, thyroid disorders, or infections can sometimes cause a change in odor, so it's important to consult a healthcare professional if you have concerns.
Sometimes, despite regular showers and deodorant, body odor sticks around. This could be due to diet (like eating spicy foods, garlic, or onions), stress sweat that mixes with bacteria, hormonal changes during puberty or menopause, or even medical conditions like diabetes or hyperhidrosis.
Therefore, perhaps a lack of vitamin D leads to neurological decline of the central and peripheral nervous system, including the cranial nerves, leading to reduced olfaction. The issue of reduced olfaction with vitamin D deficiency is not just an issue of mechanistic interest.
Zinc deficiency has been linked to stronger or unusual body odor because zinc plays a role in regulating the bacteria and metabolic processes that influence sweat. ² But, it's not the only factor. Deficiencies in magnesium or certain B vitamins may also contribute.
Vitamin C has low toxicity and is not believed to cause serious adverse effects at high intakes [8]. The most common complaints are diarrhea, nausea, abdominal cramps, and other gastrointestinal disturbances due to the osmotic effect of unabsorbed vitamin C in the gastrointestinal tract [4,8].
Vitamin C deficiency -- scurvy -- causes a putrid odor. Burns have a musty, grape-like odor. Ketoacidosis, which may result from diabetes, smells like old apples.
Let's break down which vitamins help keep your body odor in check.
Several medical conditions and diseases are associated with changes in a person's usual body scent:
Persistent body odor
If a shower can't help your body odor, it could be a sign of a magnesium deficiency. “The mineral magnesium helps in 'deodorizing' our internal organs and also helps with our body odor,” says cardiologist Robert Segal, MD, co-founder of LabFinder.
Symptoms of zinc deficiency
Anxiety and stress can cause excessive sweating. Sometimes, anxiety can cause a sudden change in the armpit's smell. Diabetes is one of the most common serious reasons.
Without the iron, the bacteria can't grow, study author Andrew Landa says. "We observed that iron is essential for bacteria to live on your skin, and by reducing its availability, the bacteria simply can't thrive," he says.
Not eating enough fresh fruits and vegetables can cause the deficiency. People feel tired, weak, and irritable. Severe deficiency, called scurvy, causes bruising, gum and dental problems, dry hair and skin, and anemia. The diagnosis is based on symptoms and sometimes blood tests.
With a vitamin C content of 2,300 to 3,150 mg per 100g of pulp, Kakadu plum (Terminalia ferdinandiana; also known as gubinge or billygoat plum) is very likely the fruit with the highest content of vitamin C.
How much vitamin C do I need? Adults aged 19 to 64 need 40mg of vitamin C a day. You should be able to get all the vitamin C you need from your daily diet. Vitamin C cannot be stored in the body, so you need it in your diet every day.
3. Nutrient Deficiencies: Mineral deficiencies, particularly Zinc, cause body odour. A zinc deficiency may occur due to underactive thyroid hormone (hypothyroidism) that produces few thyroid hormones and affect the detoxification process, resulting in body odour.
Taking zinc supplements by mouth long-term and in high doses can lead to copper deficiency. People with low copper levels might have brain and nervous system issues. Those issues may include numbness and weakness in the arms and legs.
Self-care habits that may ease sweating and body odor include:
Taking too much vitamin D leads to calcium buildup (hypercalcemia), causing physical signs like nausea/vomiting, fatigue/weakness, frequent urination & excessive thirst, constipation, and confusion/disorientation, alongside potential bone pain or kidney stones, often from supplements, not sun exposure.
Loss of taste or smell – Especially frustrating if you enjoy good food. There is also documented evidence of olfactory hallucinations for B12 deficient patients, i.e., smelling smells (usually unpleasant) that aren't actually there (medically called phantosmia).
