Effect of BrainPhyt High Dose on Cognitive Function in Healthy Older Individuals

Not Applicable

Completed

• Conditions: Age-associated Memory Impairment
• Interventions: Dietary Supplement: Placebo; Dietary Supplement: Brainphyt high dose

• Registration Number: NCT05759910
• Lead Sponsor: Microphyt

Brief Summary

The purpose of this study is to evaluate if BrainPhyt, a microalgae based ingredient may affect cognitive function parameters in older healthy individuals with evidence of age-related cognitive decline.

In a double blind, randomized manner, 40 free living males and females between 55 to 75 years with age-associated memory decline will ingest Brainphyt supplement or Placebo for 12 weeks. Cognitive function battery will be realized after 4 and 12 weeks of supplementation.
