Multivitamin Intervention and Cognitive Function
This study explores how a daily multivitamin and blueberry supplement, called Vitals+, might affect your memory and thinking abilities if you're a healthy adult. It also checks if this supplement changes levels of important nutrients in your body. We want to see if these changes are linked to improvements in thinking skills. This research is done entirely from your home over three months. You'll play online games that test your thinking, give small finger-prick blood samples, and answer health questions. The aim is to understand if Vitals+ could help keep your brain sharp and improve your nutrient levels.
At a glance
What is this study about?
You might have wondered if taking a multivitamin could help your brain work better. This study is designed to explore just that. We're looking at a specific daily supplement, called Vitals+, which contains a mix of vitamins and plant-based compounds from blueberries. Our main goal is to see if taking this supplement for three months changes how well healthy adults perform on tasks that test memory, attention, and other thinking skills.
Beyond just looking at thinking skills, we also want to understand what's happening inside your body. The study will check if taking Vitals+ changes levels of certain nutrients. For example, we'll be looking at vitamin D, which is important for many body functions, and another marker called homocysteine. High levels of homocysteine have been linked to brain health in other research, so we're curious if the supplement can help bring those levels down.
Basically, we're trying to figure out if there's a connection between taking this specific multivitamin, changes in your body's nutrient levels, and how well your brain performs. This research could give us important information about how nutrition might support brain health for healthy adults in the future.
Key takeaways
- This study investigates a multivitamin and blueberry supplement (Vitals+) for brain function.
- It's open to healthy adults over 18 years old.
- All participation happens remotely from your home over three months.
- You'll play online thinking games and provide small finger-prick blood samples.
- The study also checks if the supplement changes nutrient levels in your body.
Who may be eligible?
To join this study, you need to be a healthy man or woman over 18 years old. You must have just started taking the Vitals+ supplement or be willing to start it for the study. It's also important that you have a computer or laptop with internet access so you can take part from home.
There are some reasons why you might not be able to join. For example, if you've already been taking other vitamin supplements in the last three months, or if you eat more than four servings a week of foods that have extra B vitamins added to them, you wouldn't be eligible. Also, if you're pregnant or breastfeeding, or if you have certain health conditions like dementia, depression, or anxiety, or if you receive vitamin B12 injections, this study isn't suitable for you.
- Are you a healthy adult over 18 years old?
- Do you have a computer or laptop with internet access?
- Have you *not* taken any other vitamin supplements in the last 3 months?
- Are you *not* pregnant or breastfeeding?
- Do you *not* have a diagnosis of a neurological condition like dementia, depression, or anxiety?
This is a guide only — the research team will confirm whether you can take part.
What does participation involve?
If you decide to take part, the study will last for three months and everything will be done remotely from your own home – no in-person visits are needed. Here's a quick look at what you'll do:
**Step 1:** You'll start by playing some online games that test your brain's thinking skills. This will take about 45 minutes.
**Step 2:** We'll send you a special kit in the post to collect a small blood sample from your fingertip – you'll need about 8 drops. After that, you'll play the online thinking games again and answer some questions about your health, taking about 50 minutes. At this point, you'll begin taking the Vitals+ multivitamin once a day for three months.
**Step 3:** After three months of taking the supplement, you'll receive another finger-prick blood kit in the post. You'll give another small blood sample and then complete the online thinking games one last time, which will take about 50 minutes. This marks the end of your participation in the study.

The study will last for a total of three months from when you start taking the supplement.
What if I miss a dose of the supplement?
It's important to try and take the supplement every day as instructed, but if you occasionally forget, please mention it when you answer the health questions.
What kind of blood test is it?
It's a very small finger-prick blood test that you can do yourself at home with a kit sent to you. You'll only need a few drops of blood.
