The purpose of this study was to investigate the effects of a creatine and electrolyte formulated multi-ingredient performance supplement (MIPS) on strength and power performance. Maximal strength, total concentric work, mean rate of force development (mRFD), mean power, peak power, and peak force was determined at pre-test and post-test separated by six weeks of supplementation. Subject’s body density and body water were measured using a BodPod and Quantum X Bioelectrical Impedance unit respectively. Subjects performed three akimbo countermovement jumps (ACMJ) on a force platform. Subjects performed a one-repetition maximum (1RM) for back squat and bench press consisting of a maximal repetition test at a 90% predicted value. Eighty percent of the subjects pre-test 1RM was used for a maximal repetition test to test for performance variables including: total concentric work, mRFD, mean power, peak power, and peak force. Testing was separated by six weeks of supplementation in a double blind fashion with a placebo group for comparison. A two way mixed analysis of variance (ANOVA) was applied with an alpha level of 0.05 for all body composition, body water, akimbo countermovement jump, back squat, and bench press variables. The MIPS showed a significant increased back squat and bench press maximal strength (13.4%, p = 0.035 and 5.9%, p = 0.045 respectively), as well as total concentric work (26.5%, p = 0.024), mRFD (22.4%, p = 0.050), and mean power (17.9%, p = 0.025) for the maximal repetition bench press test at 80% of their 1RM. The placebo group had a significant decreased mRFD of -26% over the six-week supplementation. Creatine formulated with electrolytes could be beneficial for recreationally trained individuals.
