Australians are vitamin D deficient in winter
ABS National Health Measures Survey 2022–24.
You shouldn’t feel this tired.
Always tired or low on energy? Explore iron, B12, vitamin D and thyroid tests, or speak with a practitioner about where to start.
Tiredness is a symptom, not a diagnosis.
Standard blood tests often report normal results in people who feel anything but. The ranges are designed to detect disease, not to tell you why you're exhausted at 2pm every day.
OptiLabs uses functional reference ranges, calibrated to how well your body needs to perform, not just where clinical pathology begins.
12–15%
of Australian women of reproductive age have iron deficiency
AIHW Nutrition Report 2022.
Up to 40%
of vegans and vegetarians may have insufficient B12 without supplementation
