Over 65? You Might be B12 Deficient

By David Blyweiss, M.D., Advanced Natural Wellness

December 6, 2021

Did you know that being over 65 years of age is a risk factor for vitamin B12 deficiency?

It’s true. But most mainstream doctors don’t really know how to diagnose it. That’s because they receive very little training on nutrition – generally less than 20 hours of nutrition instruction during their entire time at medical school.

It’s one reason I trained in functional medicine – to learn how food and nutrition affect all systems of the body. And it sure comes in handy when it comes to diagnosing vitamin B12 deficiency. Continue reading

Taking Supplements isn’t Rocket Science

By David Blyweiss, M.D., Advanced Natural Wellness

March 22, 2021

Do you have a cabinet full of nutritional supplements that you often forget to take?

And when you do remember them, are you confused whether you should take them before you eat, with your meals or on an empty stomach? Do you wonder if it’s better to take them when you wake up or before you go to bed?

If you’re trying to plan your supplement regimen based on the multitudes of conflicting advice on Google, it probably feels almost like rocket science. I’m glad to tell you it’s not even close. Continue reading

Expensive Urine? Think Again!

By David Blyweiss, M.D., Advanced Natural Wellness

December 23, 2020

In my experience, there are people in two camps of thinking. Those who take their vitamins… and those who don’t.

People who scoff at the idea of supplementing think it’s a way to create expensive urine. After all, anything not used by your body just gets processed by your liver and kidneys — then expelled from the body.

These folks would be shocked by the number of supplement bottles lining my bathroom countertop.

I always respond to folks like this… Continue reading

Is Your Body Being Kept in the Dark?

By David Blyweiss, M.D., Advanced Natural Wellness

September 21, 2015

  • Avoid this public health crisis
  • Are you one of the “three out of four” who are deficient?
  • Don’t be afraid of the sun

Down here in South Florida, we don’t get much of a winter. But when I lived in Philly, the first seasonal snowfall was always invigorating. Of course, by the time January rolled around, I couldn’t wait for the dark and gloomy weather to end. Continue reading

Colossal Mistake Undervalues Vitamin D

By David Blyweiss, M.D., Advanced Natural Wellness
June 26, 2015

  • Why you need 15 times more vitamin D
  • Three out of four Americans are deficient
  • Reclaim your rights to the “sunshine vitamin.”

How much vitamin D do you really need?

Well, if you ask the Food and Nutrition Board (FNB), it’s not much. In fact, their recommendation of a mere 600 IU daily isn’t even a drop in the bucket. Worse yet, this number is based on flawed math. Continue reading

This is Your Brain on Telomeres

By David Blyweiss, M.D., Advanced Natural Medicine

April 17, 2015

  • Are you just a telomere length away from dementia?
  • Boost your brainpower with longer telomeres
  • Enjoy (and remember!) the best years of your life

There’s a way of thinking here in the U.S. that I find disturbing.

Most people expect to grow old…not just age, but grow old.

They expect to get sick and lose their mental faculties as they age. In their minds, once they reach 60, life will be an uphill battle all of the way.

You might be one of these people.

I’m here to tell you, it doesn’t have to be that way. It’s a defeatist attitude, and in most cases, it’s a lot of worry over nothing, since simple dietary and lifestyle changes can transform your life to a healthier more active one if you really want it.

If you plan on living a long and healthy life – and if you treat your body like you expect to become a lively and vivacious senior citizen – you can keep both your health and your memory intact well into old age.

In the last issue of Advanced Natural Medicine, I shared some tips to help you avoid Alzheimer’s disease.

Many of them mirror the methods used in Dr. Bredesen’s MEND protocol for Alzheimer’s disease. You see, he and I have a lot in common. We have a very similar focus, with the same astounding results.

A good part of the reason for this could well be because both of our protocols don’t just support brain health. They also support the length of your telomeres.

Now I mentioned this before.

The relation between telomeres and brain health is somewhat controversial. But there’s no denying that the same things that support longer telomeres are also associated with better cognitive function and a much lower risk of dementia and Alzheimer’s disease.

Previously we talked about some very simple lifestyle changes that can improve your mental abilities and stave off dementia.

Today, I’d like to share a few supplements that can exponentially decrease your risk of mental decline, along with a final tip for top-notch brain health.

Vitamin D deficiency is common here in the U.S. In fact, a whopping three out of four people here in the U.S. are running low on this nutrient.

If your doctor measures it at any of the main labs, the reference range is 30-100 pg/nl. Now, your number may be 32, and the lifeguard at the beach could be 100.

So how do you know where you should be positioned at?

Well depending on what medical issues you are dealing with, your Vitamin D level should follow the need. If you have any autoimmune issues, I look for it to be close to 70-80 pg/nl as a sufficient number.

Even if you’re only moderately deficient in vitamin D, it could increase your risk of dementia and Alzheimer’s by more than 50%. If you’re severely deficient, it can more than double your odds of these mind-robbing conditions.

In addition to that, if you have insufficient levels of vitamin D, your telomeres could be five years older than they should be.

However, deficiency of this nutrient is easy to remedy. Simply supplement with the most active form of vitamin D available. It’s called vitamin D3, also known as cholecalciferol, and it’s the one that will give you the most benefit. I suggest 2,000 IU daily, or up to 5,000 IU if you’ve been tested as deficient.

Certain B vitamins can help reduce an inflammatory marker that’s a threat to your brain health. It’s called homocysteine.

A high level of this amino acid is associated with a much greater chance you’ll end up with Alzheimer’s or dementia. It’s also linked to an increased risk of heart disease and stroke, which could leave you with vascular dementia.

And I’m sure it won’t surprise you to learn that elevated levels of homocysteine are also linked to shortened telomeres. However, there is a pretty easy way to gain control of your homocysteine levels.

The three B vitamins that support healthy homocysteine levels are:

  • Folic acid (800 mcg)
  • Vitamin B12 (1,000 mcg)
  • Vitamin B6 (20 mg)

Take these amounts daily to support both your mental faculties and the length of your telomeres.

Resveratrol, an antioxidant found in grapes and wine, turns on the anti-aging gene SIRT1. This gene promotes clearance of alpha beta, which is a hallmark of Alzheimer’s disease. It also helps protect your neurons and regulates inflammation.

At the same time, SIRT1 reduces telomere shortening and revs up your mitochondria. Both of these are critical when it comes to your brain health.

You can amplify the results you get with resveratrol by combining it with its highly potent cousin, pterostilbene. It’s a whopping four times more bioavailable than resveratrol alone. I recommend at least 50 mg of resveratrol and 25 mg of pterostilbene each day.

Omega-3 fatty acids are another winner. These fatty acids help reduce brain shrinkage, strengthen neurons, increase blood flow to the brain, protect against depression and reduce levels of beta amyloid.

Omega-3’s also help prevent your telomeres from shortening – and can even make them longer. So they pack quite a punch to keep your brain and body firing on all cylinders.

Look for a fish oil supplement that contains oil from fresh, wild-caught, deep sea fish. And make sure it’s been molecularly distilled and tested for purity (i.e., no mercury.) I recommend 4000 mg daily to protect your brain and lengthen your telomeres.

Now I’m going to share one more tip and you just might find it to be the most fun out of the bunch.

One of the most important aspects of your brain is that it’s constantly changing.

New connections are made, while others may disappear. Brain volume might shrink in some areas and expand in others. Brain cells are constantly regenerating.

It’s like a roadmap that changes every day.

But once you stop putting those skills to use, the roadmap in your brain stops creating new pathways. It starts to wither away. But there is something you can do.

Namely: Embrace a lifetime of learning.

Now, some learning activities, like studying a new language, can even make your hippocampus grow larger. But, if learning another language doesn’t appeal to you, there are many other things you might want to know more about.

Maybe you’ve always wanted to play a musical instrument, learn how to grow organic herbs or even take up writing.

The key here is to actually take the time to do it.

The tips I’ve shared with you could make the difference between living out your senior years in a nursing home, and enjoying the most memorable time of your life.

So what do you say? Are you ready to go for it? I hope you are.
