A series of systematic reviews are being undertaken, including for the Cochrane Collaboration, on the effects of nutritional supplementation on people at risk of undernutrition and obesity. Topics include vitamin D supplementation and the prevention of osteoporotic fractures, protein and energy supplementation in older people including those with hip fracture, and fish oil supplementation in critical care.
