The Quality Problem
Not all supplements are equal. An independent 2023 Australian study found 40% of pharmacy vitamin D supplements contained significantly different amounts than stated on the label — more or less. Poor bioavailability is even more common: magnesium oxide is only 4% absorbed; magnesium glycinate is 80%+.
Practitioner-grade supplements from quality suppliers match label claims and use forms that are actually absorbed.
Supplements Worth Considering for Most Adults
Evidence-based foundational supplements:
- Vitamin D3 + K2: Most Australians deficient despite sun exposure (windows block UVB)
- Magnesium glycinate: Deficiency drives anxiety, poor sleep, cramps, constipation
- Omega-3 (EPA/DHA): Anti-inflammatory, brain health, cardiovascular protection
- Quality probiotic: For microbiome support, especially post-antibiotic use
Supplements That Need Testing First
Some supplements cause harm without confirmed deficiency:
- Iron: Can cause oxidative stress if supplemented unnecessarily — test first
- Zinc: High-dose depletes copper — only use with confirmed deficiency
- B12: Only supplement with confirmed deficiency to avoid masking folate deficiency
- Iodine: Contraindicated in autoimmune thyroid disease without testing
Key Takeaways
- Quality matters enormously — form, dose, and purity all vary dramatically
- Test before supplementing iron, zinc, B12, and iodine
- Foundational supplements (vitamin D, magnesium, omega-3) benefit most adults
- We use practitioner-grade, third-party tested products only
- Always disclose all supplements at your consultation — interactions are possible
