Recent studies provide compelling evidence of liposomal superiority:
• Iron Absorption Study
In a randomized crossover trial of 25 healthy adults, a liposomal multivitamin–mineral supplement increased blood iron concentrations by 14% after four hours, while a conventional supplement showed a 6% decrease. Overall, iron exposure over six hours was nearly double with the liposomal formulation ( Science Corner: Liposomal Delivery and Supplement Bioavailability ).
• Vitamin C Bioavailability
Another randomized crossover study with ten subjects reported that a single dose of liposomal vitamin C produced 30% higher plasma peak concentrations and prolonged circulation compared with conventional formulations ( Science Corner: Liposomal Delivery and Supplement Bioavailability ).
