  • Over-the-counter allergy meds linked to Alzheimer’s and dementia
  • Are antihistamines shrinking your brain?
  • Here’s how to relieve allergy symptoms… without losing brainpower

I don’t think I know a single person who has never taken an antihistamine. In fact, the use of these over-the-counter drugs is so commonplace that it’s easy to forget that they come with serious side effects.

One of the worst, by far, is their link to the development of Alzheimer’s and dementia.

You see, many of these drugs are “anticholinergics”. In essence, they block the action of the neurotransmitter acetylcholine.

This is the chemical messenger that fuels your memory and cognitive function. It also transmits messages throughout your entire nervous system and stimulates muscle contractions.

So taking drugs that mess with it is never a good idea.

Now, just last year we found that taking anticholinergics – like Benadryl, Mucinex, Sudafed or Contac – for between one and two years increases your chances of dementia by 23%. Taking them for three or more years kicks that risk up to 54%.

MD Exposes the Hidden Danger to Your Eyes

When your eyesight starts to fail, it's a real problem. Suddenly you can't go to the grocery store... you can't get to the doctor if you have an emergency... you can't meet your friends for dinner…

Your "regular" doctor doesn't have time to keep up with the latest research. And the same goes for eye doctors. They go to school to learn how to fit you for glasses and contacts, but have no way of preventing the damage and loss of eyesight that threatens your freedom and independence.

Let me show you something that explains a LOT about how your eyes work.

In my FREE Special Report, I'll show you a HUGE, untapped resource for your eyes that safely and naturally restores clear, effortless eyesight.

And in recent months we’ve learned even more about the effect these drugs can have on your brain.

Antihistamines Shrink Your Brain

People who take anticholinergic drugs perform much worse on cognitive tests than people who don’t take them. They tend to affect your short-term memory, verbal reasoning, planning skills and ability to solve problems.

But is it simply low levels of acetylcholine that causes these problems?

That’s certainly one part of the puzzle. But there’s another one that is much more disturbing.

It turns out that folks who use these drugs also have reduced brain volume. Their brains are literally shrinking!

Plus, people taking anticholinergics have lower levels of glucose metabolism – a biomarker for brain activity – in the hippocampus. Even worse, reduced cholinergic activity is linked to an increase in hippocampal cell death.

This is the region of the brain associated with memory. And it’s the one where Alzheimer’s strikes first – even before any symptoms appear.

Cholesterol, Fat-Burning, and More!

New research supported by the National Institutes of Health revealed a chemical flaw in this near-miraculous nutrient. Human studies show we just can't absorb it. No matter how much you take...you may as well be flushing it down the toilet!

But the benefits of resveratrol – and the amazing promise of genetic rewriting – were too incredible to ignore. That's why researchers kept looking… until they found a natural resveratrol "cousin."

Now, I often see patients who take these drugs daily to control sinus problems, help them sleep better and shut down hay fever symptoms.

If this sounds like you, here are a few words of advice.

Relieve Allergy Symptoms without Losing Brainpower

To take control of allergy and hay fever symptoms, the first thing you should do is stock up on colorful fruits and veggies. Apples, citrus fruits, grapes, broccoli, red onions, tomatoes and green leafy vegetables are all packed with allergy-fighting quercetin that blocks histamine release.

I also recommend taking a butterbur supplement. It contains a substance called petasine that’s just as good as an antihistamine, but without the drowsiness. I recommend 50 to 75 mg of a standardized supplement twice a day.

Nettle is another natural antihistamine that contains anti-allergenic compounds. These help boost your resistance to pollens and molds. And it goes to work quickly. Take 870 mg of a freeze-dried extract whenever symptoms arise.

For chronic sinus problems, add the powder from one probiotic capsule to your regular nasal flushes. Use a neti pot, rubber ear bulb or spray bottle to deliver it into your nasal passages.

And if you’ve been taking an antihistamine for awhile now, it’s important to restore your levels of acetylcholine. This is also a good idea if you take other anticholinergic drugs – like sleeping pills, overactive bladder medications, Paxil or Demerol. Here’s a chart of all drugs with known anticholinergic activity.

The best way to do this is to supplement with CDP-choline (also known as citicoline). Just 100 mg daily can help improve verbal memory and effectively treat age-related mental decline.

Don’t let over-the-counter antihistamines rob you of your brainpower. Take these natural steps to boost your immunity and relieve your symptoms – without dangerous side effects.
