Collagen is the main component of connective tissues that makes up tendons, ligaments, skin and organs like the heart. In addition, we need collagen to keep our muscles strong and functioning properly.

Taking collagen may reduce the risk of heart disease in healthy individuals. Collagen gives structure to vessels and deficiency in collagen may lead to fragile and weak arteries.

Furthermore, some heart-related conditions like atherosclerosis seem to be associated with collagen deficiency. Atherosclerosis, for example, narrows arteries and increases your risk for heart attacks.

Nonetheless, there are some side effects especially for those suffering from heart diseases like people with high blood pressure.

Is collagen bad for your heart?

In this article, we are going to answer the question whether taking collagen is bad for the heart. We’re going to cover this topic from various aspects, so don’t miss this post!

One of the reasons a lot of people experience heart failure is high blood pressure. Studies show that extra collagen that is not broken down in combination with blood pressure may result in heart issues. 

We know that collagen plays an important role in shaping skin, hair, bone, heart and vessels. It also helps the organs function properly. However, collagen accumulation is likely to become fibrosis.

Fibrosis makes blood vessels and heart cells rigid. As a result, the heart needs to work harder in order to maintain blood flow throughout the body and this results in rising blood pressure. This situation may be fatal because fibrosis may advance and finally a cement-like substance surrounds the heart and blood vessels. Gradually, heart cells become harder and it is clear that they can’t work properly.

Consequently, nutritionists recommend those individuals who are suffering from high blood pressure to consult a doctor before starting taking collagen or any decision to increase the current dose. It is always a good idea to consult your doctor before adding supplements to your diet. 

Health benefits of collagen for the heart

We are going to talk about the benefits of taking collagen normally (you need to consult your doctor before consuming). What you read in the following is not true for taking too much collagen. Always check the box of your product to learn about the recommended daily dosage before consuming and starting your collagen diet. 

Collagen consumption

According to recent research, by taking enough collagen you will be at a lower risk of heart-related diseases. Collagen strengthens blood vessels and heart cells and any collagen deficiency leads to fragile vessels.

Blood circulates through the body and blood vessels are passages carrying it. These vessels include arteries and veins which play different roles although both are directly connected to the heart.

The role of arteries is delivering blood which contains nutrients and oxygen to the body cells from brain to foot fingers while veins collect CO2 and other wastes from the cells.

The vessel’s health is vital to help blood flow well throughout the body. Taking collagen aids the arteries and veins to keep a healthy structure. The stronger and more flexible the vessels, the better the blood flow.

Health benefits of collagen for the heart

Moreover, blood containing oxygen and nutrients must be circulated to every corner of the body and this is only possible when the vessels are elastic and stable enough. So collagen plays an important role not only in heart and vessels health but the entire bodily health. Studies show that consuming 16 grams of collagen daily can significantly reduce arterial fragility.

In addition, taking collagen raises the level of HDL. There are two types of cholesterol: HDL (or good cholesterol) and LDL (or bad cholesterol). Bad cholesterol sticks to blood vessels walls and this makes people at a higher risk for heart failure or even heart attacks. HDL absorbs LDL and helps the body flush it out.

How to lower high LDL

As mentioned above, high levels of bad cholesterol increases the chance of heart-related issues like heart stroke. There are different ways you can lower LDL levels from taking collagen to regular exercise. In the following, some of them are reviewed.

How to lower high LDL

Healthy diet

Change your lifestyle if needed. Foods high in fat and crabs must be restricted. Instead, try to eat more vegetables and nuts. Consult a nutritionist if possible. 

Regular exercise

You need to walk at least 20 minutes on a daily basis. Try to include regular exercise in your daily routine. The best exercise is one that makes the heart pump faster. 

Weight loss

Losing even 2 to 4 kilograms can significantly reduce LDL levels.

Giving up tobacco

Quitting tobacco just like weight loss can decrease the amount of bad cholesterol in the blood. So try to give smoking up! Smoking also decreases the amount and the quality of collagen production in your body. So, (more than) two birds with one stone. 

Consuming collagen

First of all, you are recommended to talk with your doctor before using collagen to lower LDL levels. Collagen can help you lower LDL levels by increasing the level of HDL or good cholesterol. HDL absorbs LDL and delivers it to the liver where it is flushed from the body.

Other collagen benefits

Collagen plays a key role in repair of cartilage tissues and relieving joint inflammation. Studies show that degenerative joint disorders such as osteoarthritis are associated with collagen decrease in the body. Taking collagen supplements not only reduces joint pain but improves osteoarthritis symptoms.

Other collagen benefits

Additionally, collagen helps skin look young, supple and wrinkle-free. Investigations indicate that collagen can slow skin ageing. Moreover, taking collagen peptides may help keep your skin hydrated and decrease wrinkles.


Collagen decreases the risk of heart-related diseases in heart-healthy people. It gives structure to blood vessels and any deficiency in collagen may result in fragile arteries. So collagen keeps arteries strong and flexible.

Consuming collagen can also lower bad cholesterol. Collagen increases HDL level; HDL absorbs LDL which is also known as bad cholesterol and carries it back to the liver where it is flushed out of the body.

However, excess collagen consumption can cause conditions such as heart attacks. Accumulation of collagen which is not broken down makes the heart cells rigid and this forces the heart to work harder to keep blood flow through the body resulting in high blood pressure.

As a result, if you are one of those people who are suffering from high blood pressure, it is highly recommended to talk with your doctor before starting taking collagen or any decision to increase the current dose.

Not only can taking collagen help your skin look young and fresh but plays an important role in relieving joint inflammation.
