The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

While is important to prevent vitamin D deficiency, controversies exist about optimal vitamin D intakes and concentrations. Our aim is to evaluate safety concerns with dosages of vitamin D which are routinely promoted for unsupervised public use with over the counter products. We will do this by evaluating long-term health effects for infant vitamin D supplementation, and by using a genetic approach to evaluate the causal effects of high vitamin D and calcium concentrations.
Vitamin E-bisphosphonate Conjugates: A New Therapeutic Approach Targeting Pathological Bone Loss Associated With Osteoporosis
Funder

Funding Amount
$471,984.00
Summary
Approximately 2 million Australians have osteoporosis, a disease which increases the risk of fracture and whose monetary and social costs are large and growing. The objective of this proposal is to exploit the osteotropic properties of novel compounds of vitamin E (VE) derivatives (BPVE) conjugated to bisphosphonates (BP), which will have anti-oxidant, anti-osteolytic and bone anabolic properties, and will be taken up selectively in the skeleton for the treatment of osteoporosis.
Improving Vitamin D Status And Health In Young Women
Funder
National Health and Medical Research Council
Funding Amount
$607,307.00
Summary
Vitamin D deficiency is a significant public health concern, affecting up to 50% of Australian women, potentially impacting on many chronic health conditions and increasing suffering, economic loss and premature death. This study will lead to the development of safe, effective interventions to address this important health issue. In particular we will assess the effectiveness of a lifestyle intervention to safely improving vitamin D status.
Transgenerational Effects Of Male Obesity - Mechanisms And Interventions
Funder
National Health and Medical Research Council
Funding Amount
$829,143.00
Summary
Childhood obesity is associated with obesity in either parent, and obese children tend to become obese adults, forming an intergenerational cycle that promotes obesity. We have identified paternal obesity as an important novel target for intervention to stop the progression of the obesity epidemic. This project investigates supplementation of obese fathers with folate to prevent the adverse impact of paternal obesity on subsequent generations.
Can Vitamin D Prevent Diabetes By Improving Insulin Sensitivity And Secreation In Overweight Humans?

Summary
Vitamin D is mainly produced by the action of sunlight on skin. Low levels of vitamin D are becoming more common, as we work more indoors and avoid the sun and have been associated with type 2 diabetes. In proposed study, healthy overweight people, with low vitamin D, will be given vitamin D for 16 weeks to optimise blood levels of this vitamin. We will examine the changes in sugar metabolism. This study should provide important evidence on how vitamin D protects against diabetes and will suppor ....Vitamin D is mainly produced by the action of sunlight on skin.

Creatine, A Multi-organ Protectant Against Hypoxic Injury In The Neonate
Funder

Funding Amount
$524,802.00
Summary
The WHO estimates that up to 9 million babies suffer birth hypoxia each year, leading to 29% of global neonatal deaths, and significant rates of severe disability. We hypothesise that creatine, given as a supplement to the mothers diet during pregnancy, will protect her babies organs should low oxygen around the time of birth occur. The low cost of creatine is particularly relevant for rural and remote communities and the developing world where, currently, there are no effective therapies.
Determining The Role Of Vitamin D In The Development Of Asthma And Allergic Diseases In High Risk Families
Funder
National Health and Medical Research Council
Funding Amount
$351,127.00
Summary
Allergic diseases like asthma, eczema and hay-fever, prevent our children from getting a healthy start to life, and we don’t know how to prevent these conditions. Vitamin D levels may be critical in the development of childhood asthma and allergies, and they can be easily modified! Using a group of 620 children who we have followed for 20 years, we will identify the role of vitamin D levels in the development of allergic conditions, and factors that modify these relationships.
A Novel Nanoparticulate Iron Supplement And Its Effect On The Gastrointestinal Tract.
Funder
National Health and Medical Research Council
Funding Amount
$671,995.00
Summary
Iron deficiency and iron deficiency anaemia are major global health issues. Currently available iron supplements can lead to gastrointestinal side effects. We have developed a new type of oral iron supplement that (in animal studies) is as effective as conventional treatments, but without their limitations. In this project we will investigate the effect of this supplement on the gastrointestinal tract to ensure its safety and to provide preliminary data for future clinical trials in humans.
Mechanisms Of Intestinal And Systemic Iron Homeostasis In Early Infancy

Funding Amount

Summary
Iron is essential trace element for normal health. Iron requirements are particularly high during early postnatal life to meet the needs of the growing infant. To accommodate these needs, intestinal iron absorption is extremely high at this time. We have previously shown that the iron absorption mechanism during suckling differs from that in adults and this project explores that mechanism in more detail. These studies have important implications for infant nutrition and dietary supplementation.
