Introduction • American dietary trend is progressively diverging from proper nutrition. • Today’s RDA values date back to 1968 (Smith 2005) • B12 and Folic Acid • U.S. & Canada Fortify Foods (Oakley 2004) • Homocysteine reduction (Wald 2002) • Vitamin C (Shapiro et al. 1983) • Vitamin D (Johnson and Kimlin 2006)
Introduction • Vitamin E • In vascular disease (Brown and Crowley 2005) • Deficiency symptoms (Higdon 2004) • Vitamin K (Environmental Nutrition 2006) • In blood clotting • bone development
Introduction • Many people rely on the multivitamin to provide micronutrients • The vitamin may not disintegrate in the stomach • Intestinal absorption is beyond the scope of this experiment. • Hypothesis – multivitamin mass is directly proportional to disintegration time. • Null Hypothesis– mass is not directly proportional to disintegration time.
Methods and Materials • ConsumerLabs home test modified method • 125mL portion vinegar • 125mL portion of distilled water • Three brands of multivitamin • Erlenmeyer flask with stopper, and thermometer. • Heating Mantle • Stopwatch
Figure 1 Figure 1 comparing multivitamin mass against disintegration time in seconds
Results • Multivitamin disintegration times were not correlated in any way with mass. • All pellets weighed in within .05g of 1.5g • Pellets of the same type took a similar time per environment. • Pellets of different types took vastly different times to disintegrate.
Summary & Conclusions • Centrum and Equate both dissolve in under 400 seconds. • OneSource takes more than 1200 seconds. • Neither pH nor heat affected the disintegration time for a brand.
Conclusion • Multivitamin mass is not directly proportional to disintegration time. • Further testing is needed to determine the significance of continuous stabilized motion as force acting in disintegration. • Additional research is needed covering the contributions of ingredient quantities, and pellet coating or compaction methods to multivitamin pellet disintegration.
