Boosting Brain Health: Do Supplements Really Help? (Part 1)

We’re all getting older. And while there’s not too much we can do about it, for most of us, our hope is that we age with grace, dignity, and some semblance of normal cognitive and physical functioning. Others also hope to preserve their youthful appearance.

When diabetes comes into the picture, things can get murky. By this I mean that some evidence points to the link between Type 2 diabetes[1] and a decrease in the ability to concentrate, problem solve, and provide thoughtful answers to questions. Other research indicates that people who have uncontrolled diabetes have almost twice the risk of cognitive dysfunction as people without diabetes. Why? It’s possible that constant high glucose levels impair small blood vessels in the brain, leading to ministrokes. Another possibility is that high glucose levels damage neurons (nerve cells) in the brain.

And not to spread doom and gloom, but evidence shows that people with both Type 1[2] and Type 2 diabetes have a 30% to 65% higher risk of developing Alzheimer disease compared with people who don’t have diabetes. Some researchers have coined a “new” type of diabetes, called “type 3 diabetes” that is marked by insulin deficiency in the brain. Folks at Rhode Island Hospital and Brown University discovered that insulin[3] and certain kinds of protein are made in the brain; low levels of both can lead to degeneration of neurons, increasing the risk for Alzheimer disease.


So that brings us to this question: What, if anything, can be done to prevent a decline in cognitive function? Is there anything that we can do, take, or eat that will keep our brains and nervous system functioning at a high level as we get older? The answer? Maybe.

Dietary Supplements
It would be so easy to pop a pill or two and expect miraculous results. The reality, though, is that, at least when it comes to aging, there’s not a lot of evidence that any one particular supplement can help slow mental decline. But it’s early days yet, and hopefully scientists will discover the fountain of youth. Here are a few of the leading candidates that have been marketed as “brain supplements”:
