These plant pigments found in berries like strawberries and blueberries have antioxidant properties that can work synergistically with glutathione to combat free radicals.

Tip: Opt for a variety of colourful fruits throughout the week to maximize your intake of beneficial vitamins and antioxidants.

The Humble Onion and Its Garlicky Cousins

Onions, garlic, and shallots are superstars when it comes to supporting glutathione production. Here’s why;

Sulfur Compounds

These vegetables contain unique sulfur-containing compounds like allicin (found in garlic) that contribute to glutathione synthesis.

Tip: Finely chop or mince these vegetables to release their beneficial sulfur compounds and maximize their impact. Add them to stir-fries, soups, or enjoy them raw in salads (if your stomach can handle it).

Leafy Green: Spinach and Beyond

Leafy greens like spinach, Swiss chard, and collard greens are nutritional champions. They offer a wealth of benefits for glutathione:

Folate

This B vitamin plays a crucial role in amino acid metabolism, which is essential for glutathione synthesis.

Vitamin K

Studies suggest vitamin K may also support glutathione production, although more research is needed.

Tip: Darker leafy greens tend to be richer in nutrients compared to lighter varieties. Experiment with different leafy greens to add variety and flavor to your meals.

Milk Thistle: A Liver-Loving Herb with a Glutathione Boost

Milk thistle has a long history of use for supporting liver health. Research suggests it may also offer benefits for glutathione.

Silymarin

This active compound found in milk thistle has antioxidant and anti-inflammatory properties. It may also support glutathione production in the liver, our body’s primary detoxification organ.

Tip: Consult a healthcare professional before using milk thistle supplements, especially if you have any underlying health conditions.

Whey Protein: A Post-Workout Power Up for Glutathione Synthesis

Whey protein, a component of milk, offers a concentrated source of;

Cysteine:

This key amino acid is readily available in whey protein, making it a valuable post-workout option to support muscle repair and potentially boost glutathione levels.

Tip: Choose unsweetened whey protein powder and mix it with water or your favorite smoothie for a quick and convenient protein boost.

Selenium-Rich Nuts and Seeds: Brazil Nuts Take the Lead

Nuts and seeds are a fantastic source of healthy fats, but some stand out for their selenium content;

Selenium
