Scurvy is treated with vitamin C supplementation, and symptoms typically begin improving within one to two weeks of starting treatment. The standard approach uses high doses initially, then tapers down over one to three months. Because the human body cannot produce or store large amounts of vitamin C, treatment needs to both replenish depleted stores and establish a dietary pattern that prevents recurrence.
Standard Treatment for Adults
Treatment follows a three-phase approach that front-loads vitamin C to rapidly restore your body’s reserves, then gradually reduces the dose to a maintenance level.
In the first two to three days, the typical recommendation is 1,000 to 2,000 mg of vitamin C daily. This high initial dose quickly raises blood levels from the near-zero range (a plasma level below 0.2 mg/dL suggests scurvy) back toward normal. After that initial push, the dose drops to about 500 mg per day for the following week. Then for the next one to three months, you take around 100 mg daily to fully rebuild your body’s reserves and allow tissues to heal.
Most people take vitamin C by mouth as tablets, powder, or liquid. In hospital settings where someone can’t absorb oral supplements reliably, or when symptoms are severe, intravenous vitamin C may be used: typically 1,000 mg daily for three days, followed by 250 to 500 mg twice daily for about a month.
Treatment for Children
Children are treated with lower doses. The American Academy of Pediatrics recommends starting with 300 mg of vitamin C daily for the first week, given orally, intramuscularly, or intravenously depending on the child’s situation. After that first week, the dose drops to 100 mg daily for one to three months. A daily multivitamin is often added alongside the vitamin C, since children with scurvy frequently have other nutritional gaps as well.
Doctors will sometimes start treatment before lab results confirm the diagnosis, especially when symptoms are obvious. Waiting days for bloodwork to come back while a child is in pain offers no benefit when vitamin C supplementation carries minimal risk.
How Quickly Symptoms Improve
The good news is that scurvy responds to treatment relatively fast. Fatigue and general malaise are usually the first symptoms to lift, often within the first few days. In published case reports, significant improvement across symptoms like bleeding gums, skin hemorrhages, and corkscrew-shaped hairs has been documented within 10 days to two weeks of starting vitamin C.
More stubborn symptoms, particularly joint pain and deep bruising, can take longer. Some cases take four to six weeks for full resolution. The timeline depends partly on how severe and prolonged the deficiency was before treatment started. Someone who has been deficient for months with widespread bleeding into joints and muscles will naturally take longer to heal than someone caught earlier.
One important caveat: while soft tissue damage generally heals completely, skeletal damage from severe or prolonged scurvy doesn’t always fully reverse. In cases where weakened bones have fractured or compressed, structural changes like spinal deformity can persist even after vitamin C levels return to normal. This is uncommon but underscores why early treatment matters.
Risks of High-Dose Vitamin C
For most people, the doses used to treat scurvy are safe and well-tolerated. The main concern is kidney health. Your body converts excess vitamin C into a waste product called oxalate, which can crystallize in the kidneys. At doses above 1,000 mg per day, oxalate excretion increases by 6 to 13 mg daily, raising the risk of kidney stones.
For people with healthy kidneys, this is a minor and temporary risk that resolves as the dose tapers down. For anyone with pre-existing kidney problems, however, oxalate buildup can cause more serious damage to the kidney’s filtering tubes. Kidney stone formation has been reported after just two intravenous doses of vitamin C in a patient with existing kidney dysfunction. If you have a history of kidney stones or kidney disease, your treatment plan may need to be adjusted accordingly.
Foods That Prevent Recurrence
Supplements fix the immediate deficiency, but long-term prevention comes from diet. The daily recommended intake of vitamin C is 90 mg for adult men and 75 mg for adult women. If you smoke, add 35 mg to those numbers, because smoking increases the rate at which your body burns through vitamin C.
Reaching that threshold is straightforward with even modest amounts of fruits and vegetables. Some of the richest sources per serving:
- Red bell pepper, raw (½ cup): 95 mg, more than a full day’s requirement
- Orange juice (¾ cup): 93 mg
- Orange (1 medium): 70 mg
- Kiwifruit (1 medium): 64 mg
- Green bell pepper, raw (½ cup): 60 mg
- Broccoli, cooked (½ cup): 51 mg
- Strawberries (½ cup): 49 mg
- Brussels sprouts, cooked (½ cup): 48 mg
Even foods you might not associate with vitamin C contribute meaningful amounts. A baked potato provides 17 mg, and half a cup of cooked cabbage has 28 mg. For people whose scurvy developed because of a restrictive diet, food aversions, or limited access to fresh produce, identifying just two or three reliable vitamin C sources that fit into daily eating habits is the most practical path to prevention.
Why Scurvy Happens in the First Place
Scurvy develops after roughly one to three months of consuming very little vitamin C. It’s rare in developed countries but not as rare as most people assume. The people most at risk aren’t sailors on long voyages. They’re individuals with extremely limited diets: people with severe food restrictions due to autism or sensory processing issues, older adults living alone with poor nutrition, people experiencing food insecurity, those with alcohol use disorder, and individuals on highly restrictive diets that eliminate most fruits and vegetables.
Vitamin C is essential for making collagen, the structural protein in skin, blood vessels, bones, and connective tissue. Without it, those structures weaken and break down. That’s why the classic symptoms of scurvy, including bleeding gums, easy bruising, joint pain, poor wound healing, and fatigue, all trace back to the same root cause: your body can’t maintain or repair its connective tissues.
Because these symptoms overlap with many other conditions, scurvy is often missed or misdiagnosed initially. If you recognize these signs in yourself and your diet has been lacking in fruits and vegetables, the condition is worth raising with a healthcare provider. A simple blood test measuring plasma vitamin C can confirm the diagnosis, and treatment is both inexpensive and effective.
