Important Considerations for Australian Context
The majority of multivitamin preparations do not actually contain all 13 vitamins, despite being labeled as "multivitamins." 1 This descriptor doesn't guarantee completeness or appropriate proportions relative to nutritional requirements. 1
Vitamin D deserves special attention in Australia: Most adults obtain only 5-10% of their vitamin D requirement from dietary sources, with sunlight exposure being the primary source. 2 A serum 25-hydroxyvitamin D level of ≥50 nmol/L is required for optimal musculoskeletal health. 2 When sun exposure is minimal, supplementation of at least 600 IU (15 µg) daily for those ≤70 years and 800 IU (20 µg) daily for those >70 years is recommended. 2
Safety and Regulatory Framework
Dietary supplements are used by 47% of the Australian population, making them the most common type of complementary medicine. 3 Many vitamins and minerals are subject to legal restrictions as scheduled medicines depending on dose. 3 Consumers face overdose risk when the same ingredient appears in multiple products. 3
All adverse events with vitamins and minerals should be reported to the Australian Therapeutic Goods Administration. 3
When Standard Multivitamins May Be Insufficient
For specific medical conditions (particularly post-bariatric surgery), a standard complete multivitamin alone is typically insufficient. 4 In these cases, additional targeted supplementation of iron, calcium, vitamin D, vitamin B12, and other nutrients is required beyond what a complete multivitamin provides. 4, 5
Athletes with high nutrient turnover, especially female athletes who often fail to meet energy requirements, may require additional supplementation beyond a standard multivitamin. 6 The approach should account for athlete sex, recommended dietary intake, supplement dose/timing, and potential food-drug interactions. 6
