A Study Investigating the Effect of Floradapt Mature Immune Defense on Nutrient Uptake and Digestive Health in a Healthy Elderly Population

Phase 2

Completed

• Conditions: Healthy
• Interventions: Dietary Supplement: Floradapt Mature Immune Defense + Multivitamin; Dietary Supplement: Placebo + Multivitamin

• Registration Number: NCT04147923
• Lead Sponsor: Kaneka Americas Holding Inc.

Brief Summary

This trial will be investigating the effect for Floradapt Mature Immune Defense on nutrient uptake and digestive health in a healthy elderly population. Approximately 120 healthy older adults will be enrolled into the study and will consume either the probiotic or placebo supplement for 84 days and complete questionnaires as well as provide blood samples for nutrient uptake analysis (for 50 participants), immunological markers, and general markers of health. Saliva samples will be provided for analysis of sIgA and cortisol.
