What are Good Natural Food Sources of Glutathione?

Glutathione is one of the most important components in the human body. It’s a naturally-produced antioxidant of the liver that’s crucial for detoxification, boosting your immune system, and numerous other things. While the body produces its glutathione, we sometimes need more than the liver can make.

While people often use oral supplements, injections, or IV therapy to boost their levels, this article will look at good natural glutathione foods.

Sulfur-Rich Foods

Amino acids are one of the main components necessary to produce glutathione, and sulfur-rich foods happen to be packed with them. Garlic, shallots, and onions, in particular, are excellent sources of amino acids, which then help produce glutathione.

Other foods high in sulfur include broccoli, bok choy, cauliflower, Brussel sprouts, kale, and cabbage. You may not be a fan of these foods, but they truly are great glutathione food sources.

Vitamin C

Not only is Vitamin C is extremely healthy for your immune system, but it bonds extremely well with glutathione. Vitamin C can work with and supplement glutathione as it defends your immune system. It’s also a great way to make glutathione last longer, reuse it, or produce more if your body needs it.

Green Veggies

This option might not be the most popular one, especially with kids, but green veggies are among the most glutathione rich foods. Green veggies such as spinach, asparagus, okra, and any of the options listed in the section on sulfur-rich foods, are naturally rich in glutathione. Avocados are also an excellent option and its among the foods high in glutathione, so stock up on the guacamole!

If green veggies aren’t your thing, you can also opt for protein as another option. Two of the core components needed to create glutathione, cysteine, and glycine, are contained in protein. You can absorb protein in the form of powder, supplements, or foods that are protein-rich. Some dietary sources of glutathione and protein include beans, meats, lentils, nuts, sunflower seeds, and more.


Herbs are one of the most underrated foods in the world. They are extremely beneficial to your health in a number of ways, and producing glutathione happens to be one of them. While not all herbs are rich in glutathione, the milk thistle is a specific one you should be on the lookout for.

Milk thistle is known for protecting the liver, which is the organ responsible for producing glutathione. In addition to milk thistle, turmeric is another herb shown to aid in the production of glutathione within the liver. Herbs are some of the natural sources of glutathione boosting foods and they are great for your overall health too.
