Brief summary
The objective of this open-label, exploratory study is to investigate the efficacy of BDNF Essentials® on cognition in a healthy adult population with self-reported memory complaints. As there is a dearth of available literature on BDNF in this study population, the current study is designed to understand the role of BDNF to inform potential future studies.
Detailed description
The objective of this open-label, exploratory study is to investigate the efficacy of BDNF Essentials® on cognition in a healthy adult population with self-reported memory complaints. As there is a dearth of available literature on BDNF in this study population, the current study is designed to understand the role of BDNF to inform potential future studies. The study population represents a target group of individuals who would benefit from safe and efficacious nutraceuticals for the support of cognitive function. This transitional stage from normal cognition to cognitive impairment is viewed as an opportune window for intervention. This population of participants is being recruited to expand on previously published work on these individual ingredients while limiting confounding variables that could influence outcomes.

Exclusion criteria
* Women who are pregnant, breast feeding, or planning to become pregnant during the study * Allergy, sensitivity, or intolerance to the investigational product's active or inactive ingredients * Dementia and/or cognitive decline or use of prescribed medications used to for dementia and/or cognitive decline (Section 6.3.1) * Prescribed medications for depression that may affect concentration, attention and performance as assessed by the QI (Section 6.3.1) * Current use of supplements used for cognition or mood support unless on a stable dose (Section 6.3.2) * History of epilepsy, brain injury or trauma as assessed by the QI * Self-reported confirmation of sleep disorder as assessed by the QI * Prescribed or over-the-counter medications or supplements used for sleep (Section 6.3.1 and 6.3.2) * Self reported colour-blindness * Prescribed use of antibiotics within 1 month of baseline (Section 6.3.1) * Prescribed use of anticoagulants/antiplatelets (Section 6.3.1) * Prescribed or chronic use of over-the-counter anti-inflammatory medications (Section 6.3.1 and 6.3.2) * Current use of supplements containing the ingredients in the IP unless willing to washout (Section 6.3.2) * Current employment that calls for rotating shift work or shift work that will disrupt normal circadian rhythm in the last 3 weeks * Travelled across 1 or more time zones in the last 3 weeks and/or is anticipating more travel during the study * Use of medical cannabinoid products * Current chronic use of cannabinoid products (\>8 times/month) and is unwilling to stop for the duration of the study beginning 1 week prior to baseline. History of chronic use and occasional use to be assessed by QI on a case-by-case basis * Use of tobacco, nicotine, or e-cigarette products within 12 weeks of baseline and during the study period * Self-reported alcohol or drug abuse within the last 12 months * Self-reported confirmation of HIV-, Hepatitis B- and/or C-positive diagnosis * Autoimmune disease including Type I diabetes or are immune compromised * Self-reported current or pre-existing thyroid condition.
