Zinc, Inattention & the SLC6A3 Gene

Written by Joe Cohen, BS | Last updated:

What if there was a simple, cheap and natural way to fix one of the biggest cognitive issues facing people today?

The issue? Inattention. And the simple fix? It could be zinc.

Zinc is an extremely important mineral, in fact it’s the second most abundant trace mineral in our bodies after iron.

To understand how zinc is linked to attention span, we first need to talk about your genes…

We all share genes with the same overall function, for example the SLC6A3 gene, which codes for a protein that transports dopamine into cells. However, this gene, like others, comes in several different variations… some of which work better than others.

Thankfully, we at SelfDecode have the knowledge to combat your bad genes and coach you on the path to optimal health!

So if your dopamine transporting SLC6A3 gene isn’t functioning well, what does this mean?

Well dopamine plays an important role in emotion regulation and our ability focus. So, if your dopamine system isn’t functioning correctly, you’re more likely to develop attention related issues and ADHD.

Bad variants of the SLC6A3 gene can increase dopamine transport out of your brain, leaving you with a decreased ability to focus!

Interestingly, a lot of commonly-prescribed ADHD medications work by physically blocking the dopamine transport out of the brain.

But where does zinc come into play?

Like the drugs prescribed for ADHD, zinc is naturally able to increase the overall amount of dopamine in your brain.

And more dopamine = better focus.

But wait, the benefits of getting enough zinc don’t stop there…

Zinc is actually highly important to several other genes, such as the ADA gene. Certain variants of this gene can lead to a buildup of adenosine, which leads to fatigue and difficulty focusing.

Fortunately, Zinc enables the gene to work more effectively by removing adenosine.

That’s why it’s extremely important to take a look at your genes and find out if you’ve got genetic variants that are making it more difficult to focus.

When you know what your genetic weaknesses are, you’ll be able to know exactly what changes, like supplementing with zinc, you need to make in order to increase your focus by 10X (or even more!).
