Does Collagen Damage Your Liver?

Collagen is a protein that helps to give skin, tendons, ligaments, and bones strength and elasticity. It’s also found in the lining of our stomachs, intestines, lungs, and kidneys. The protein is produced naturally by our bodies, but when we consume too much it can cause problems for our organs.

The Effects of Collagen on the Body

Collagen takes years to produce, which is why, as we get old, we tend to lose some of the collagen in our bodies. Collagen supplements can help replace some of that collagen. 

Collagen supplements are typically made from either bovine or marine sources. Marine collagen is thought to be more easily absorbed by the body, but both types have been shown to be effective. In addition to improving skin and joint health, collagen has also been shown to boost metabolism, promote gut health, and reduce inflammation.

The Potential Dangers of Taking Collagen Supplements

Though often advertised as a “miracle” skin care solution, collagen supplements can actually do more harm than good. However, our bodies produce collagen naturally, and there is no evidence to suggest that taking supplemental collagen has any benefits.

One study found that participants who took collagen supplements had a higher risk of developing liver disease.

Additionally, collagen supplements can interact with other medications, making them less effective. For these reasons, it is best to avoid taking collagen supplements altogether.

Before you take collagen supplements, it’s a good idea to speak to your doctor. Your doctor will check your health history and medical condition.

Factors that Can Damage the Liver

There are several factors that can damage the liver, including:

Alcohol consumption: Excessive alcohol consumption can cause inflammation and scarring (cirrhosis) of the liver as well as an increased risk of developing serious medical conditions such as alcoholic hepatitis, fatty liver disease, and cirrhosis.

Medications: Some medications, such as acetaminophen (Tylenol), certain antibiotics, blood pressure medications, antidepressants, anticonvulsants and some sleeping pills can cause liver damage if taken in large doses or for an extended period of time.

Medical conditions: Certain medical conditions such as viral hepatitis (A-E), autoimmune hepatitis, Wilson’s disease and non-alcoholic fatty liver disease can all lead to primary or secondary hepatic injury or failure which may require hospitalization.

Herbal supplements: While many herbal supplements have been found to be safe when used according to directions by healthy adults, some herbs such as kava and comfrey have been linked with hepatotoxicity when taken in large doses or for an extended period of time.

How to Support Liver Health

In addition to limiting alcohol consumption, taking medications as prescribed, eating a healthy diet and getting vaccinated against viral hepatitis there are other steps you can take to support liver health.

To prevent the spread of infections that may lead to liver damage it is important to practice good hygiene habits.

This includes washing your hands frequently, especially if you work in a healthcare setting or come into contact with blood or bodily fluids.

Additionally, regular exercise can help improve overall health and reduce stress which can be beneficial for the liver.

Finally, reducing exposure to toxic substances such as chemicals and pollution should also be considered when looking at ways to support liver health.

When to Seek Medical Attention

When it comes to the potential for collagen supplements to damage your liver, if you experience any symptoms such as abdominal pain, fatigue or jaundice (yellowing of the skin and whites of the eyes), it is important that you seek medical attention.

Your healthcare provider can assess your individual situation and advise you on how best to proceed.

In some cases, they may recommend further tests such as a blood test or ultrasound scan in order to determine whether there are any underlying issues with your liver health.

It is also essential that you inform them about any dietary supplements or medications that you are taking, so they can take this into account when making their diagnosis and providing treatment advice.

How to Tell if You’re Having an Adverse Reaction to Collagen

If you’re thinking about taking collagen supplements, it’s important to be aware of the potential side effects. While collagen is generally safe, some people may experience an adverse reaction. Here are a few signs that you may be having an adverse reaction to collagen:

– gastrointestinal distress, including bloating, gas, and diarrhea
– skin rashes or itching
– headaches
– dizziness or lightheadedness

If you experience any of these symptoms after taking collagen supplements, stop taking the supplements and consult your doctor. They’ll be able to determine if the collagen is the cause of your symptoms and advise you on whether it’s safe for you to continue taking it.

How Can You Tell if Your Liver is Damaged?

Surprisingly, you may not experience any symptoms at all in the early stages of liver damage. As the liver becomes more diseased, you may begin to experience fatigue, weakness, weight loss, and loss of appetite. You may also develop hills on your nails, and your skin and eyes may take on a yellowish tint.

In the most advanced stages of liver damage, you may experience confusion, coma, and death.


In conclusion, collagen supplementation and topical collagen products are not linked to liver damage.

However, other factors like alcohol consumption, medications (prescription or over the counter), medical conditions, and certain herbal supplements can have a negative impact on the liver.

To support overall liver health it is recommended to limit alcohol intake, follow instructions for any medication you may take (including taking them with food if recommended), eat a balanced diet rich in fruits and vegetables, get vaccinated as necessary for your age group/area of residence, and practice good hygiene habits such as frequent hand-washing.

If you have any concerns about your own personal risk factors for developing issues related to your liver health it is important that you speak with a healthcare provider so they can advise you on how best to manage those risks.
