- A vicious cycle that compromises blood flow
- What do telomeres have to do with it?
- How to stop the cycle in its tracks
The first thing that probably pops into your head when you think of poor red blood cell production is anemia. And, yes, it’s true. People with anemia have a low red blood cell count, or RBC. Many of these folks are low on iron, so it’s pretty easy to fix the problem.
But there’s another cause of low RBC you likely haven’t heard about. And it can create a pretty vicious cycle that could cause you to age prematurely. At the same time, it also increases your chances of heart attack, stroke, dementia and more.
Now, I’ve talked about telomeres before. These are the protective DNA caps on the end of your chromosomes that shorten each time your cells divide. The shorter they get, the more quickly you age.
Well, it turns out shorter telomeres can decrease your RBC. This can be quite a problem, because your red blood cells are what deliver fresh oxygen to all of the tissue and organs in your body. If you’re not producing enough of them, you could be starving your body of much-needed oxygen and nutrients it needs to thrive.
Red blood cells also transport and release nitric oxide (NO) throughout your entire cardiovascular system. Now, if you’re a regular reader of Advanced Natural Wellness, you know how important this gas is to your circulation.
NO is what keeps the inner lining of your blood vessels relaxed so blood can flow freely all through your body. Without enough nitric oxide, your blood has to pump harder. This results in high blood pressure that damages your arterial walls and opens the door to plaque build-up.
So, not only do you have a shortage of red blood cells, you also end up with compromised blood flow. It’s no wonder patients with anemia often have problems with poor circulation!
A low RBC also has ties to heart failure, microvascular complications, and dementia.
Let’s talk about how all of this ties together, what it means for you, and what you can do about it…
You can see what’s happening here, right?
Shortened telomeres reduce red blood cell count. This, in turn, lowers activity of nitric oxide. So, things are already running a little sluggishly.
Now here’s the real humdinger: Lower NO levels also reduce telomerase activity, which may cause your telomeres to shorten even further. This creates a never-ending cycle of shortened telomeres, lower RBC, lower NO… which causes even shorter telomeres, lower RBC and decreased NO, and so forth.
As if that’s not bad enough, shortened telomeres affect the size of your red blood cells. It makes them bigger, resulting in a condition called macrocytosis. The effect shortened telomeres have on red blood cell size is actually equivalent to smoking or drinking.
A regular CBC blood test will show the size of your red blood cells. But mild macrocytosis is very often overlooked as not being important.
If left unchecked, macrocytosis can lead to fatigue, difficulty concentrating, paleness, dizziness and shortness of breath. In severe cases it can result in confusion, dementia, poor balance, depression and numbness in the arms and legs.
Thankfully, there are ways to extend your telomeres and stop the cycle in its tracks. Here’s the advice I give to my patients…
Omega-3 fish oil may be one of the most important nutrients for telomere support. It not only slows down telomere shortening, it also helps to lengthen them. And this can happen in as little as four months. Look for a high-quality 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). Aim for 1200 mg. of EPA and 800 mg. of DHA daily for telomere lengthening.
Look for a cold-water fish oil supplement that contains at least 360 mg. of DHA and 540 mg. of EPA.
Folic acid and Vitamin B12 supplements can both keep your telomeres longer than if you don’t supplement with them. Deficiency in these nutrients is also a common cause of macrocytosis. I suggest 800 mcg of folic acid and 500 to 1,000 mcg of B12 daily.
Green tea is another big winner when it comes to your telomeres. People who drink three cups of green tea a day have telomeres that are about five years younger than those who don’t drink it.
If you don’t like green tea, you can always take it in supplement form. Look for one that contains Epigallocatechin Gallate (EGCG) and is standardized to contain 60% polyphenols. For the most impact, set a goal of 240 to 320 mg of polyphenols every day.
Vitamin D deficiency is common here in the U.S. If your levels are low, your telomeres could be five years older than they should be. If you choose to supplement, look for a formula that contains the vitamin D3, also known as cholecalciferol. I suggest 2,000 IU daily and up to 5,000 IU if you’ve been tested as deficient.
Multi-vitamins normally include folic acid, vitamin B12 and vitamin D, which I mentioned above. This may explain why women who take a daily multivitamin have telomeres that are about 10 years younger than women who don’t.
Adopting a Mediterranean-style diet and getting moderate physical activity can both help protect your telomeres from shortening, too. And to make sure your NO levels are up to par, look for a plant-based NO booster that has beetroot juice as its main ingredient. These plant-based formulas vary from one manufacturer to another, so make sure to compare ingredients and dosage information.
