Malnutrition Recovery Support Protocol

The Malnutrition Recovery Support protocol is built on high-calorie oral nutritional supplement drinks between meals and on protein of 1.2 to 1.5 g per kg of body weight a day, the amount experts advise for older adults who are ill or malnourished. Its other rows are a multivitamin, vitamin D, zinc, iron, vitamin B12 with folate, omega-3 and thiamine. In a Cochrane review of 62 trials in older people, supplement drinks raised weight by 2.2%, and fewer undernourished people died. Take iron only if a blood test shows a shortage. Anyone with severe or unexplained weight loss needs a clinician or dietitian, because restarting food too fast can cause dangerous drops in blood minerals.

High-Calorie Nutritional Supplements and Protein Supplements are the core of this stack, with 7 supporting supplements. Each row gives the amount the protocol lists and the grade our evidence database holds for that supplement in Malnutrition Recovery Support.

We are re-verifying the studies cited on protocol pages; only confirmed citations are shown.

What the evidence says

  • Supplement drinks raise weight, and may save lives in people who are already undernourished. A Cochrane review of 62 trials with 10,187 older people at risk of malnutrition tested extra protein and energy, usually as ready-made sip drinks. Weight rose by 2.2% compared with control. Deaths were not lower overall, but were lower in trials of people who were already undernourished (2,461 people), and complications fell. The drinks did not improve day-to-day function or shorten hospital stays, most trials were of poor quality, and side effects included nausea and diarrhea. (PMID 19370584)
  • Dietitian-led support in hospital improved outcomes. In a trial of 2,088 medical inpatients at nutritional risk in eight Swiss hospitals, a plan set by specialist dietitians to reach protein and calorie goals cut poor outcomes at 30 days (death, intensive care, unplanned readmission, major complications or loss of function) from 27% to 23%, and deaths from 10% to 7%, compared with standard hospital food. Side effects from the nutrition support were no more common. (PMID 31030981)
  • A high-protein drink gave mixed results after discharge. In malnourished adults aged 65 or over in hospital for heart failure, heart attack, pneumonia or COPD, 328 took a high-protein supplement drink that also contained HMB twice a day and 324 took a placebo drink. The main outcome, death or unplanned readmission within 90 days, did not differ. Deaths alone were lower with the drink, 4.8% against 9.7%, a secondary result. (PMID 26797412)
  • The protein amount matches expert advice. An ESPEN expert group advises 1.0 to 1.2 g of protein per kg of body weight a day for healthy older people, 1.2 to 1.5 g for older people who are malnourished or at risk because of acute or chronic illness, more in severe illness or injury, and daily physical activity for all. The PROT-AGE group gives the same 1.2 to 1.5 g range for most older adults with acute or chronic disease. (PMID 24814383; PMID 23867520)
  • Evidence for a routine multivitamin is thin. In 910 people aged 65 or over living at home who did not already take vitamins, a daily multivitamin and mineral for one year did not reduce infections or improve quality of life. The trial did not select people who were malnourished, so it says little about replacing a shortage that a blood test has found. (PMID 16081445)

Safety and when to see a clinician

  • Refeeding risk: after severe weight loss or days of eating little or nothing, restarting food can cause refeeding syndrome, which can be life-threatening. Expert groups define it as falls in blood phosphorus, potassium or magnesium, or organ problems from thiamine shortage, within 5 days of restarting calories. Warning signs of risk include a low BMI, large unplanned weight loss, little or no food intake, and a history of alcohol or drug misuse. Expert advice is a slow, stepwise start with electrolytes, vitamins and close monitoring, so this needs a medical team. Thiamine is only one part of that care; the mineral drops need blood tests. (PMID 32115791; PMID 29429529)
  • Find the cause first. Unplanned weight loss in people over 65 is linked with more illness and death. Cancer accounts for up to a third of cases, and medicines can dull taste or cause nausea. A 2021 review advised tests for the cause, help with eating, a medicine review and social support, and did not recommend high-calorie supplements or appetite stimulants for this group. See a doctor before relying on supplements. (PMID 34264616)
  • Kidney disease: the PROT-AGE group says older people with severe kidney disease (eGFR below 30) who are not on dialysis may need to limit protein. Ask your kidney team before raising protein. (PMID 23867520)
  • Take iron only after a blood test shows a shortage, at the dose your clinician sets, and keep iron tablets out of children's reach. Tell your clinician about every supplement you take, including the multivitamin, since several rows of the stack contain the same minerals.
