NCT05431751

Brief Summary

Clinical proof-of-concept study comparing the acute. effects of an algae-based dietary supplement on immune surveillance and alertness. This study involves twenty-four participants composed of healthy adults, who will be taking either a placebo or supplement at different times. Testing for immune status, cytokine levels, and immune responsiveness will be conducted to determine the acute impact of the supplement on immune function compared to a placebo. Long term effects and lingering effects will be tested using the same parameters, following a consumption period of one week, as well as a washout period of one week.

Study Arms (1)

Experimental Group A

EXPERIMENTAL

Crossover study: Participants will be consuming placebo on a clinic day at least 1 week prior to a clinic day where they will consume the active intervention. Following the second clinic day, the participant will consume active intervention for 7 days. The participant will then undergo a washout period of 7 days.

Dietary Supplement: Whole Algae

Interventions
