Glutathione: Health Benefits and Food Sources

Updated: Oct 3, 2022

Glutathione is a natural substance in your body that's important for maintaining health. It belongs to a class of compounds called thiols, which are made up of sulfur and oxygen. Glutathione has many body functions, from helping fight off infections to protecting against toxins and heavy metals. This article will explore glutathione and how it can benefit your health.

Glutathione is a natural substance in your body that's important for maintaining health.

What is glutathione?

Glutathione is a tripeptide comprised of three amino acids: glutamate, cysteine, and glycine. It is the most abundant intracellular antioxidant in the body and helps protect against free radicals.

Glutathione can be found in almost every cell of your body, including your muscles, organs, and skin. Glutathione has many functions in the body, such as helping to maintain your immune system, liver health, detoxification pathways, and hormone production.

What are the benefits of glutathione?

Glutathione is an antioxidant and a natural detoxifier. Glutathione is also a powerful anti-aging compound, and it's also been shown to boost the immune system. Glutathione's numerous benefits, so let's examine how it can benefit your health.

  • It helps neutralize free radicals in the body that cause damage to cells and DNA

  • It provides a protective effect against oxidative stress

  • It supports optimal liver function by aiding in the breakdown of toxins (including alcohol)

  • Research on glutathione shows promise for treating certain types of cancer

Glutathione for skin health

If you're looking to improve the health of your skin, glutathione could be the answer. Glutathione is an antioxidant that helps to prevent premature aging and damage from free radicals. It can also help to reduce acne, sun damage, and inflammation.

Here are some tips for integrating glutathione into your diet:

  • Eat more fruits and vegetables (especially leafy greens). These foods contain antioxidants that protect cells against harmful substances called "free radicals."

  • Consume healthy fats like omega-3 fatty acids found in salmon or walnuts, which boost glutathione levels in the body.

Glutathione for hair growth

Glutathione treats hair loss, including alopecia areata and male pattern baldness. It can also be used to treat dandruff and damage caused by coloring your hair.

Glutathione is an important antioxidant that helps reduce oxidative stress on your body. The more glutathione you have, the better off you'll be!

Glutathione and Cancer

One of the most common ways glutathione helps people is its role as an antioxidant. A powerful and essential antioxidant, glutathione can help to reduce oxidative stress.

Many people don't realize that oxidative stress is one of the critical factors leading to cancer. Oxidative stress occurs when too many free radicals are floating around in your body, which can cause damage to your cells and DNA. When you have too much oxidative stress inside of you, it can cause inflammation and cell damage - both of these things play a role in causing cancer!

Glutathione helps fight off these free radicals before they can cause any harm at all by donating an electron (becoming a "free radical" itself) so that instead of damaging healthy tissue, it just bounces off onto another molecule instead; thus neutralizing any potential harm from free radicals like this one might have caused otherwise!

Can you overdose on glutathione?

Glutathione is a natural antioxidant found in your body and helps fight against toxins. It's not a drug, so you can't overdose on glutathione. All of the side effects of taking supplemental glutathione are mild and temporary.

Glutathione is a critical component of the body's immune system and can be taken as an antioxidant supplement for its health benefits, including providing support for the lungs and liver.

How can you increase your glutathione levels?

Increasing glutathione levels can be done through diet and supplementation. Sulfur-containing foods are the best way to boost your body's glutathione levels, but if these foods aren't enough for you, taking an L-cysteine supplement may be a good idea.

If you find that increasing your intake of sulfur-containing foods such as garlic, onions, and eggs doesn't give you a big enough boost in glutathione production, supplementing with L-cysteine might be what you need. You may also want to consider taking a glutathione supplement if the sulfur content of your diet is already high enough to support normal glutathione levels without supplementation.

You can't overdose on glutathione.

You can't overdose on glutathione, which is a naturally-occurring amino acid. Glutathione is produced in the body and is also found in certain foods. It's one of the most vital antioxidants that help protect cells from damage caused by free radicals.


Glutathione is a powerful antioxidant that can help your body fight disease and maintain health. You can get this naturally occurring substance from food or supplements, but before taking any supplements, speak with your doctor about your options for naturally increasing glutathione levels.
