Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Clinical-proof-of-concept study comparing the acute immune effects as well as the lasting and lingering effects of a dietary supplement, and a placebo. The dietary supplement is composed of whole Euglena gracilis algae, produced using a proprietary fermentation technique.

24 subjects will participate in a placebo-controlled, double-blinded, cross-over study design, wherein they will be taking placebo, or dietary supplement each separated by a 1-week washout period to evaluate rapid effects. Following which the subjects will also be taking placebo or dietary supplement continuously for 1 week each, to evaluate the long term and lingering effects.

For acute evaluation, blood samples are taken 1 hour after participants arrive, the dose is then administered. Samples are take 1 hour and 2 hours following administration. For long-term and lingering evaluation, blood samples are taken 1 hour after participants arrive. At all blood sample collections, a spit sample will also be taken for salivary IgA testing.

A series of immune panels will be used to determine the acute impacts on immune surveillance, immune cell activation status, immune cell priming, and cytokine profiles. Ex vivo immune challenges and salivary IgA testing will be used to determine the direct impacts on immune cells.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Experimental Group A

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.
