☀️ 1 in 3 Australians are vitamin D deficient by the end of winter.
As the days shorten and the sun sits lower, our bodies simply can’t make the vitamin D they do in summer. Deficiency jumps from around 14% at the end of summer to 36% by the end of winter, and in the south-eastern states it climbs to nearly 1 in 2. 🌥️
And you can’t eat your way out of it. Only about 5–10% of your vitamin D comes from food, and standard multivitamins (32–200 IU) just don’t cut it.
Vitamin D matters for strong bones and muscles, a resilient immune system, steady energy, and mood through the darker months yet you often can’t feel it dropping until levels are low. That’s why winter is the time to be proactive. 💛
A general guide to supplementing (always look for D3):
🔸 Everyday maintenance: 1,000–2,000 IU daily
🔸 Mild deficiency (30–49 nmol/L): 1,000–2,000 IU daily
🔸 Moderate–severe (below 30 nmol/L): 3,000–5,000 IU daily for 6–12 weeks, then back to a maintenance dose
A quick tip: more isn’t better. Above 5,000 IU/day should be under medical supervision, and the end of winter is the perfect time for a simple GP blood test, your level sets your dose. 🩸
