Glutathione might not be a household name like Vitamin C or calcium, but it’s one of the most powerful antioxidants your body naturally produces.
Often dubbed the “master antioxidant,” glutathione is crucial for cellular repair, detoxification, immunity, and healthy skin.
It protects your cells from oxidative stress, supports liver function, and slows the ageing process, what more could you ask for?
While your body produces glutathione on its own, poor diet, stress, pollution, alcohol, and ageing can deplete your levels.
The good news? Certain foods can help you boost your natural glutathione production or provide it directly.
Here are five glutathione-rich foods to add to your diet, your body (and skin) will thank you!
1. Spinach
Spinach isn’t just Popeye’s go-to for muscle power; it’s also a great source of glutathione. Raw spinach contains high levels of this antioxidant and is also packed with Vitamin C, E, and beta-carotene, which work synergistically with glutathione to neutralise harmful free radicals.
How to eat it:
For maximum benefit, enjoy spinach raw in salads or smoothies. Cooking can reduce its glutathione content, so if you prefer it sautéed or steamed, make it quick and gentle.
Bonus tip: Pair it with a squeeze of lemon juice to help with nutrient absorption
2. Avocado
Avocados are more than just Instagram-worthy toast toppings. They’re rich in healthy fats, fibre, and yes glutathione. In fact, avocados are one of the few fruits that contain a significant amount of this antioxidant, helping your liver flush out toxins and supporting skin clarity.
How to eat it:
Add sliced avocado to your morning toast, mash it into guacamole, or throw it into smoothies for a creamy texture and a nutrient punch.
Why it works:
Avocados also help increase levels of HDL (good) cholesterol and reduce inflammation—two things that help your body naturally produce and retain glutathione.
3. Broccoli
Broccoli is part of the cruciferous vegetable family, which is famed for its detoxifying benefits. Not only is broccoli rich in glutathione, but it also contains sulforaphane, a compound that stimulates your body’s own glutathione production.
How to eat it:
Lightly steam broccoli or eat it raw in salads to preserve the glutathione content. Avoid overcooking, as heat can degrade its nutrient profile.
Did you know?
Broccoli also supports liver health, which is the central hub of glutathione production and detoxification
4. Garlic
Don’t let its size fool you, garlic is a powerhouse when it comes to boosting your body’s antioxidant levels. While garlic doesn’t contain glutathione directly, it provides sulphur compounds (like allicin) that are essential for your body to produce it.
How to eat it:
Chop or crush raw garlic and let it sit for a few minutes before cooking to activate the allicin. Add it to salad dressings, dips, or sautéed vegetables for both flavour and benefits.
Why it matters:
Sulphur is a key building block for glutathione synthesis. Foods like garlic ensure your body has the raw materials it needs to stay strong and resilient
5. Asparagus
Asparagus is one of the best natural sources of glutathione. Rich in vitamins A, C, E, and K, along with fibre and folate, this slender veggie supports detoxification and cellular repair.
How to eat it:
Roast, grill, or steam asparagus lightly and toss it with olive oil and lemon juice. Serve it as a side dish or toss into pasta, salads, or omelettes.
Fun fact:
Asparagus has long been used in traditional medicine for its anti-inflammatory and liver-supportive properties, both of which align with glutathione’s job description
Glowing skin is not far
Glutathione might be doing its job quietly in the background, but its impact on your overall health is massive. From supporting immunity and glowing skin to keeping your liver and cells functioning optimally, this antioxidant is worth your attention.
By regularly consuming foods that are either high in glutathione or promote its production, you’re giving your body a daily detox boost and a glowing future. So next time you’re planning your meals, remember to toss in a few of these delicious glutathione-rich ingredients. Your cells will thank you!
