Sepsis Recovery Nutritional Support Protocol
Sepsis is a medical emergency in which the body's response to an infection damages its own organs. If you think someone has sepsis, call 911: fast hospital care with antibiotics comes first, and supplements have no role in the acute illness. In intensive care, trials found no benefit from IV thiamine, selenium or high-dose vitamin D, and IV vitamin C raised the risk of death or organ failure in a trial of 872 adults. Evidence for supplements during recovery is very limited. Expert reviews recommend follow-up care, a medicine review and rehabilitation after discharge, planned with the care team.

What the evidence says
- In the LOVIT trial, 872 adults with sepsis on blood-pressure drugs in intensive care got IV vitamin C (50 mg per kg every 6 hours for up to 4 days) or placebo. Death or lasting organ failure by day 28 was more common with vitamin C: 44.5% against 38.5%.
- An early non-randomized study of 94 patients reported fewer deaths with a mix of IV vitamin C, hydrocortisone and thiamine. Randomized trials since then have not shown that benefit: a 2020 meta-analysis of 4 trials found IV thiamine (vitamin B1) did not change deaths, lactate levels or organ failure in septic shock.
- In a trial of 1,089 people with severe sepsis or septic shock, high-dose IV selenium did not lower deaths at 28 days (28.3% against 25.5% with placebo).
- In 1,078 critically ill adults with low vitamin D, a single large dose of vitamin D3 (540,000 IU) did not lower deaths at 90 days (23.5% against 20.6% with placebo). The trial included critically ill adults in general, not only people with sepsis.
- In a trial of 1,223 critically ill adults with multiple organ failure, glutamine did not improve outcomes, and deaths in hospital and at 6 months were higher with glutamine than without it.
- After discharge, about half of sepsis survivors recover, and about one in six have severe lasting problems, such as new physical limits, memory and thinking problems, anxiety, depression or PTSD. There is little trial evidence for any specific recovery treatment; experts recommend physical therapy.
Safety and when to see a clinician
- Sepsis is a medical emergency. Call 911 for signs of a serious infection such as confusion, fast breathing, a racing heart, a very high or low temperature, clammy skin or extreme pain. Speed matters: in a study of 49,331 patients, each hour's delay in antibiotics was linked to a higher risk of death in hospital. Don't try supplements first.
- The stack is for recovery after hospital care only, and only with your care team's agreement. Don't take glutamine while still seriously ill: in critically ill adults with organ failure it was linked to more deaths.
- About 40% of survivors go back into hospital within 90 days, often with a new infection. Get care quickly for fever, breathlessness, new confusion or worsening weakness after discharge.
- Survivors often go home on new or changed medicines, and reviews advise checking them after discharge. Ask a pharmacist or doctor before adding any supplement.
