This trial tests whether adding a twice-daily nutritional drink to standard care helps adults aged 55 and older regain weight and muscle strength after being hospitalized for an acute illness. Participants are at risk of malnutrition and have low grip strength. Half receive the d…

Preterm infants are born with low vitamin A stores and rely on breast milk to meet their needs, putting them at risk for deficiency. This trial tests whether giving mothers of very preterm infants (born before 29 weeks) a daily high-dose vitamin A supplement for four months can i…

This study tests whether giving caregivers a weekly bulk container (7-day supply) versus daily single-use sachets (1-day supply) of a nutrient supplement improves how much children actually consume. About 500 caregivers of children aged 6-24 months in northern Ghana will try both…

This study tests whether adding Vitamin C, Omega-3 fatty acids, lignin, and lactulose to standard care can improve recovery in 108 adults after coronary artery bypass grafting (CABG). Participants will take the supplements daily for 10 weeks starting 15 days after surgery. The go…

This study compares a high-intensity loading dose of vitamin D2 to standard weekly dosing in 52 patients with newly diagnosed aggressive non-Hodgkin lymphoma who are also receiving standard chemotherapy. The goal is to see if the high-dose approach normalizes vitamin D levels fas…

This phase III trial tests a vitamin B12 injection (hydroxocobalamin chloride) in 20 children aged 6 months to 18 years with a specific type of methylmalonic acidemia (cobalamin C deficiency). The goal is to see if the injection can normalize levels of certain acids in the blood …

This study tests whether giving vitamin K2 (MK-7) supplements to breastfed infants or their breastfeeding mothers can prevent vitamin K deficiency at 2 months of age. About 134 healthy, full-term babies who received standard vitamin K shots at birth will be enrolled. Some infants…

This study looks at whether Pilates or aerobic exercise can help new mothers improve their vitamin D and calcium levels, which often drop after childbirth. Sixty healthy women, 6-12 weeks after giving birth, will do either Pilates or aerobic exercise for 12 weeks. The goal is to …

This trial evaluates a new device called Tasso+ that lets people collect a small blood sample from their upper arm, potentially replacing the traditional finger-prick or venous blood draw for vitamin D testing. Researchers will compare vitamin D levels measured from the Tasso+ sa…

This study examines whether vitamin D levels are linked to asthma control, lung function, and oxidative stress in Egyptian adults with bronchial asthma. Researchers will measure vitamin D in the blood, assess asthma symptoms with a standard test, and check lung function and marke…

This observational study is investigating whether vitamin D levels are linked to cholesterol and other blood fats in obese adults with type 2 diabetes. Researchers will measure vitamin D status and lipid profiles in 150 participants from a diabetes clinic in Cairo. No treatments …

This observational study will check vitamin C levels in 40 people with osteoporosis, comparing those who have had a spine fracture to those who haven't. The goal is to see if lower vitamin C is more common in the fracture group. No treatment is given; the study simply measures an…

This study looks at vitamin D levels in 63 critically ill children (ages 1 month to 12 years) admitted to the ICU with severe breathing infections. Researchers will measure vitamin D in the first 24 hours and compare it to how severe the infection is and the risk of death. The go…

This study tests whether vitamin D extracted from fish waste is as effective as synthetic vitamin D at raising blood levels in healthy adults with mild deficiency. 48 participants will take either fish-derived or synthetic vitamin D daily for 3 months. The goal is to see if a sus…

This study looks at whether three proteins in urine—RhoA, NGF, and BDNF—can help doctors diagnose and monitor overactive bladder in children aged 4 to 18 who also have low vitamin D. Researchers will measure these proteins before and after standard behavioral therapy (urotherapy)…

This study in Assiut, Egypt, will check 116 children aged 2-15 for intestinal parasites to see if these infections are more common in malnourished kids compared to healthy ones. The goal is to understand how parasites like Giardia and hookworms might cause or worsen malnutrition …

This study looks at how different types of anemia—like iron deficiency or thalassemia—can change HbA1c levels, a common test for diabetes, in people who do not have diabetes. Researchers will compare HbA1c results between 100 non-diabetic adults with various anemias and a healthy…

This study will check how common vitamin B12 deficiency is in preterm infants (born before 37 weeks) at the time they go home from the hospital. Researchers will measure B12 and related markers in blood samples from 40 babies. The goal is to understand if these vulnerable infants…
