A randomized, blinded, placebo-controlled direct-to-consumer study of health and wellness products on mental clarity and other health outcomes

This is a randomized, blinded, placebo-controlled study conducted with adult participants, age 21 and older and residing in the United States.

Eligible participants will (1) endorse a desire for better concentration, (2) indicate an interest in taking a health and wellness product to potentially help their concentration, and (3) express acceptance in taking a product and not knowing its formulation until the end of the study.

Participants with known liver or kidney disease, heavy drinkers, and those who report they are pregnant, trying to become pregnant, or breastfeeding will be excluded. Those taking certain medications will be excluded.

Self-reported data are collected electronically from eligible participants over 7 weeks. Participant reports of health indicators will be collected during 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.
