The Top Nutrients Australians Are Low In — And How Functional Testing Fixes the Problem
Most Australians believe they’re eating “pretty healthy,” yet functional testing tells a very different story. In 2025, the vast majority of test results we review at Wellbeing George Nutrition show consistent gaps — even in clients who eat extremely well.
This article breaks down the top nutrient deficiencies, why they matter, and how the right testing creates targeted, life-changing improvements.
1. Vitamin D — The Australian Paradox
Australia has incredible sunlight, yet vitamin D deficiency remains widespread.
Low vitamin D impacts:
immune function
inflammation
mood
hormonal balance
energy levels
bone health
Why it’s missed:
GP blood tests often use reference ranges that are too broad. Functional testing looks at optimal ranges, not “just enough to avoid disease.”
2. Magnesium — The Stress Buffer We Burn Through Quickly
Magnesium deficiency is a national epidemic.
High stress, alcohol, coffee, processed food and poor sleep drain magnesium daily.
Symptoms include:
tight muscles
headaches
anxiety
poor sleep
constipation
blood sugar instability
We routinely see low intracellular magnesium on functional tests even when blood tests appear “normal.”
3. B Vitamins — Especially B12, B9 (Folate) & B6
This is critical for:
methylation
mood & neurotransmitters
detoxification
energy production
pregnancy planning
Low B-vitamins contribute to high homocysteine — one of the strongest indicators of accelerated ageing.
4. Omega-3 Fatty Acids — The Anti-Inflammation Powerhouse
Omega-3:6 ratios are one of the strongest predictors of:
cardiovascular health
inflammation
mood disorders
cognitive decline
We see >80% of clients deficient.
5. Choline — The Forgotten Nutrient
Essential for:
brain health
liver detox
methylation
pregnancy
lipid metabolism
Not enough Australians eat eggs, liver or choline-rich plants.
Testing Is Better Than Guessing
At Wellbeing George, we use:
micronutrient panels
methylation analysis
inflammation markers
organic acid testing
homocysteine
omega-3 index
…to give an exact map of what your body needs.
