Erections need good blood flow. Here's why that matters for your heart and what you can do next.
READ THE 4 REASONS
ED can be linked to poor blood flow.
Blood must flow to your private area for an erection to happen. When blood flow is poor, it can be hard to get or keep an erection. Studies have found a link between ED and heart disease.
That's why ED isn't always just a sex problem, low testosterone, or a sign of age. It can also be a sign that it's time to check your heart.
The arteries that help with erections are much smaller than those near your heart.
Why does that matter? Small arteries may show signs of poor blood flow before large ones do. This means ED can be an early sign of blood vessel disease.
And it's one reason why doctors may check your heart when you have ED.
Your heart and erections both need healthy blood vessels.
Blood vessels must open and relax so blood can flow. But when they don't work as they should, blood flow can slow down. This can affect both your heart and your erections.
That's why doctors may look at blood flow when they check for the cause of ED. Some compare it to a "check engine light" for heart health.
Your body may give you an early warning.
Studies show that in some men, ED can start 2 to 5 years before signs of heart disease.
That doesn't mean ED always leads to a heart attack. But it can be a sign to check your heart sooner.
If you have new or lasting ED, talk to your doctor. It may help you find a problem early.
Erections need blood flow. So does your heart.
That's why it's smart to care for the blood vessels that help both work well.
Here are three ways to start.
Your body needs blood to reach your heart, muscles, and organs.
Good blood flow helps your body work as it should.
Your heart pumps blood through vessels that reach every part of your body.
That includes your private area. So when you care for your arteries, you care for more than just your heart.
Blood pressure and cholesterol tests can tell you a lot about your heart.
If you have ED, it may be time to check these numbers with your doctor.
Nattokinase is an enzyme from natto, a food made in Japan. Scientists have studied how it may affect your heart and blood vessels. Here's what two published studies found.
In one trial, adults took nattokinase or a placebo for 8 weeks. A placebo has no active ingredient.
The group taking nattokinase had a larger drop in blood pressure than the placebo group.
Their top number fell about 5.6 points more than the placebo group.
A 12-month study looked at records from adults taking nattokinase. Plaque is buildup inside an artery.
Researchers reported lower plaque measurements in the neck arteries of the group taking 10,800 FU daily.
The 3,600 FU group did not show the same changes. Because this was not a randomized trial, it cannot prove nattokinase caused the results.
Each full daily serving of Valera gives you 10,800 FU of nattokinase. That's the same daily dose used in the 12-month study.
These studies looked at blood pressure and artery health, not ED. They do not show that nattokinase treats ED, improves erections, or prevents heart disease. The 12-month study reviewed patient records and was not a randomized trial. Its findings cannot prove cause and effect. If you have new or ongoing ED, speak with a healthcare professional. Ask your clinician before using nattokinase, especially if you use blood thinners or have a bleeding disorder.
