Primary outcomes

The measured values of the standardized score of composite memory of Cognitrax at 12 weeks after consumption (12w)

Key secondary outcomes

1. The measured values of the standardized score of composite memory of Cognitrax at four and eight weeks after consumption (4w, 8w)

2. The amount of change of the standardized score of composite memory of Cognitrax between screening (before consumption; Scr) and 4w, 8w, or 12w

3. The measured values and amounts of changes from Scr of the standardized scores of Neurocognition Index (NCI), verbal memory, visual memory, psychomotor speed, reaction time, complex attention, cognitive flexibility, processing speed, executive function, social acuity, reasoning, working memory, sustained attention, simple attention, and motor speed of Cognitrax at 4w, 8w, and 12w

4. The measured values and amounts of changes from Scr of total score of self-administered dementia checklist and the scores of "subjective cognitive decline" and "subjective decline in daily living functioning" at 4w, 8w, and 12w

5. The measured values of all of the items of self-administered dementia checklist at 4, 8, and 12w
