The purpose of this trial is to learn how a multivitamin combined blueberry polyphenol supplement (Vitals+) influences cognitive function in healthy adults. A secondary aim is to see how the biochemical level of nutritional factors change with the supplement. This study will be completed fully remote (from the participants home without in-person visits). Participants will be asked to compete three steps over the course of 3 months: Step 1: Participants will be asked to complete an online cognitive function game (45 minutes) Step 2: Participants will receive a fingertip blood sample kit in the post to measure nutritional markers in the body (requiring 8 drops of blood). They will then be asked to complete the same online cognitive function game and answer some questions about their general health (50 minutes). After this, participants will be requested to start their multivitamin (Vitals+) subscription, once a day for 3 months. Step 3: This final step is the same as step 2. After 3 months participants will receive another fingertip blood sample kit in the post (requiring 8 drops of blood) and asked to complete the cognitive function games again (50 minutes). This will mark the end of the study. How these measurements responded to the multivitamin supplement will then be measured.
