Shield Your Brain From Alzheimer’s With This Simple Trick
We’re spending about $4 billion a year on Alzheimer’s research.
And let’s be honest… there’s not much to show for it.
If you’ve ever had a loved one with this terrible disease, you probably learned a hard truth…
The mainstream drugs being used to treat Alzheimer’s don’t do a darned thing.
The treatments for Alzheimer’s are ineffective… so your best bet is to avoid developing the disease in the first place.
That may have just gotten a lot easier to do, thanks to some Irish scientists.
And the best part? Keeping Alzheimer’s from taking root doesn’t have to cost you a dime.
A new study out of Ireland shows that keeping your vitamin D levels up may help prevent the types of brain changes that can lead to Alzheimer’s.
The study followed about 800 middle-aged adults for 16 years. Those who started with the highest levels of vitamin D in their blood had lower levels of tau proteins later on.
And these are the same tau proteins that are considered a key marker of Alzheimer’s disease.
Could healthy vitamin D levels really stop the biological processes that lead to Alzheimer’s?
Based on what we know from previous research, sure.
Vitamin D can help calm inflammation in the brain, which we know is a trigger for tau. Vitamin D also interacts with key enzymes that play a role in tau accumulation.
Now, the research on all of this is early… but there are so many health benefits to vitamin D, that it just makes sense to keep your levels up.
And that doesn’t have to cost you anything.
As you know, my preferred way to raise vitamin D levels is through sun exposure. Make sure you’re getting adequate sunlight every day – which is much easier now that sunnier weather is here.
But if you’re concerned about your vitamin D status, talk to your doctor about getting tested and supplement as necessary.
Your future brain health may literally depend on it.
