A randomized, double-blind, placebo-controlled direct-to-consumer study of health and wellness products on cognitive function and related health outcomes

This is a randomized, double-blind, placebo-controlled study conducted with adult participants, residing in the United States.

Eligible participants will (1) endorse a desire for better concentration, (2) have the opportunity for meaningful improvement (at least 20%) in their primary health outcome, and (3) express acceptance in taking a product and not knowing its formulation until the end of the study.

Participants that report a known cardiac dysfunction, liver or kidney disease may be excluded. Participants that report a known contraindication or with well-established, significant safety concerns due to illness will be excluded. Heavy drinkers and those who report they are pregnant, trying to become pregnant, or breastfeeding will be excluded. Participants that report taking medications with a known contraindication or with well-established, significant safety concerns will be excluded.

Self-reported data are collected electronically from eligible participants for 7 weeks. Participant reports of health indicators will be collected at baseline, throughout the active period of study product use, and in a final survey. All study assessments will be electronic, there are no in-person visits or assessments for this real-world evidence study.
