For Youth – The Protect
For Youth took a different path with The Protect, skipping the single-ingredient route and building a formula around glutathione recycling. Each vegan capsule packs 250mg of Setria® Glutathione—a clinically studied brand—plus 100mg of Sulfodyne® Sulforaphane from broccoli seed extract. That pairing is designed to help your body make better use of its own glutathione, not just flood it. One study showed a 38% drop in oxidative stress markers, which for busy Singaporeans means less internal wear and tear from long hours and UV exposure. Everything is third-party tested, so you know what’s on the label is what’s inside. They’re an online-only brand, with straightforward ordering and delivery right to your door.
This is the pick for someone who nerds out over ingredients and wants something beyond basic glutathione. If your goal is to slow down skin aging and keep your energy steady without adding six different bottles to the counter, The Protect slots right in. No need to juggle multiple supplements lah—one capsule, clean study-backed formula, done. Website: For Youth – The Protect.
VitaHealth L-Glutathione Plus
VitaHealth’s L-Glutathione Plus tablets are that familiar face you’ll spot in Guardian or Unity. They combine L-Glutathione with vitamin C, which is a practical move—vitamin C helps glutathione do its job better and adds its own antioxidant punch. The formula is geared towards skin brightening and guarding against UV damage, exactly what we need when our daily commute involves blazing sun and glass buildings reflecting it right back at you. At SGD27.90 and up, they’re kind on the wallet, so it’s the supplement you can take consistently without feeling the pinch.
If you want something steady, proven, and you prefer popping into a store rather than ordering online, this is the one. It’s the no-fuss, ‘buy-discount-when-on-offer’ type of supplement that still delivers on glow. The company is based at 26 Kallang Place #05-04, Singapore 339157, and you can reach them at +65 6278 2778. But most people just pick up a bottle at their neighbourhood pharmacy—usual opening hours apply, around 9am to 9pm. VitaHealth.
21st Century Fair & Lovely
21st Century’s Fair & Lovely VC + Glutathione Capsules are the budget-friendly option that doesn’t feel cheap. The vegan capsules pair pure L-Glutathione with vitamin C for absorption, and the whole promise is a more even, brighter skin tone without breaking the bank. It’s widely available in local pharmacies and online retailers, so you can add it to your cart alongside your usual painkillers and plasters. Great for anyone starting their glutathione journey or those who just want a straightforward, affordable antioxidant boost.
If you’re already taking a multi but want that extra skin-evening effect, this slots in nicely. 21st Century Vitamins.

Now Foods Glutathione
Now Foods takes a disciplined, no-frills approach: 500mg of reduced glutathione in a capsule with no artificial colours or flavours. They’ve built their reputation on transparency and USA-grade quality testing. The 500mg strength makes it a good middle-ground dose—not too low, not mega high—ideal for supporting everyday detox and immune function. For minimalists who just want pure glutathione without any extra bells, this gives you full control. Pair it with your own vitamin C or a specific diet plan.
They have a local office at 65 Ubi Road 1, Oxley Bizhub, Singapore 408729; call +65 6744 6288 for enquiries. The actual purchase happens online through retailers like iHerb or Lazada. Now Foods.
Toniiq Ultra High Purity
Toniiq comes in strong—literally—with 1000mg of glutathione per serving at 98% purity. Made in a GMP-certified facility, it’s marketed at those who want a therapeutic-grade dose without paying luxury prices. The capsules are substantial, and you only need one a day, so a bottle lasts. This one’s a die-die-must-try for anyone who wants high dose and good value. A single capsule packs a punch—perfect for those with a higher oxidative load, like gym rats or people working long shifts in a hazy city.
It’s an online-only purchase for Singapore, available through their website or major health platforms. Toniiq.
Biofinest L-Glutathione Collagen
Biofinest combines L-Glutathione with collagen and vitamin C inside a single vegan capsule, priced from SGD44.95. The thinking is that while glutathione works on brightening and detox, the collagen supports skin elasticity, joints, hair and nails. After a few weeks, friends might ask if you’ve been sleeping better—the collagen and glutathione really do a number on tired-looking skin. If your main motivation is appearance—glowing skin, stronger nails, less creaky joints after the gym—this three-in-one saves you buying separate bottles. It’s especially helpful for older adults or anyone who feels their skin needs a bit more structural support alongside antioxidant protection.
Order through their site or e-commerce platforms. Biofinest.
NutriFlair Liposomal Glutathione
NutriFlair uses liposomal technology to wrap 700mg of Setria® L-Glutathione in a phospholipid complex, which helps more of it survive digestion and reach your cells. This non-GMO, vegan formula is aimed squarely at people who want better absorption and are willing to pay SGD53.00 for it. You’ll find it on Amazon.sg and perhaps other online health stores. If you’ve tried other glutathione brands and felt they did little, the liposomal delivery might be the difference. It’s also a good pick if you’re managing chronic fatigue or just want to feel more resilient during flu season.
User feedback often mentions steadier energy and a noticeable lift to overall well-being. NutriFlair.
Quicksilver Scientific Liposomal Glutathione
Quicksilver Scientific takes a completely different route: a liquid liposomal formula with a lemon mint flavour. Each serving delivers 100mg of Opitac Reduced Glutathione. Because it’s already in liquid liposomes, absorption begins in the mouth, making it potentially the fastest way to get glutathione into your bloodstream. No pills, no water—just a small squirt, hold for a bit, and swallow. The convenience is a bit shiok, especially on rushed mornings. Perfect for people who struggle with swallowing capsules or want rapid antioxidant support before a workout or stressful meeting.
It’s soy-free and fits into even the most minimalist morning routine. Quicksilver Scientific.

How to choose
Glutathione supplements come in different forms: reduced glutathione as a capsule (like Now Foods or Toniiq), paired with vitamin C for better synthesis (VitaHealth, 21st Century), using liposomal technology for improved absorption (NutriFlair, Quicksilver Scientific), or even combined with collagen (Biofinest). First, ask yourself: do you want a basic antioxidant top-up, or are you chasing a visible skin-brightening effect? If the latter, a product with added vitamin C or liposomal delivery might give faster results.
Second, consider price per serving. You’ll find options from SGD27.90 to SGD53.00 for about a one-month supply—liposomal liquids tend to be costlier, but some people find the absorption worth it. Much like comparing Online Grocery Options in Singapore, you’ll want to check shipping fees and return policies if you’re buying from overseas sites. And as you’d scrutinise Photo Printing Services in Singapore for quality, look for third-party lab testing or GMP-certified manufacturing. That tells you the brand is serious about what’s inside.
If you’re after a multi-tasking beauty supplement, the collagen blends make sense. For those who want pure glutathione without extras, stick to Now Foods or Toniiq. And if swallowing capsules is a sian thing for you, the liquid from Quicksilver solves that problem entirely.

Frequently asked questions
What is L-Glutathione?
L-Glutathione is a powerful antioxidant made naturally by the body. It helps neutralise free radicals, supports the liver’s detox pathways, and plays a role in maintaining a healthy immune system. Levels can drop due to stress, poor diet, or ageing, which is why people supplement.
Is it safe to take L-Glutathione daily?
For most people, yes—the supplements on this list are formulated for daily use. Start with the recommended dose on the label and watch how your body responds. If you have any medical conditions or are on medication, it’s wise to check with a doctor first.
How long does it take to see results?
This varies. Some notice brighter skin and more energy within a few weeks, while deeper benefits like detox support may take a couple of months of consistent use. Pairing it with vitamin C, as several products here do, can help your body use it better.
What’s the difference between liposomal and regular glutathione?
Liposomal glutathione gets wrapped in a layer of fat (phospholipids) that protects it through the digestive system, so more reaches your cells. Regular reduced glutathione in capsules still works, but the absorption percentage may be lower. You’ll find both in this list, from NutriFlair and Quicksilver (liposomal) to Now Foods (standard).
Can glutathione really lighten skin?
Glutathione interrupts the production of melanin, which can lead to a gradual lightening of skin tone for some people. The effect is usually subtle and works best when combined with sun protection. Brands like VitaHealth and 21st Century add vitamin C to support this process.
Are these supplements vegan-friendly?
Several are: For Youth The Protect, 21st Century Fair & Lovely, NutriFlair Liposomal, and Biofinest L-Glutathione Collagen all state they’re vegan or non-GMO. Others like Now Foods and Toniiq use gelatin capsules, so check the label if that matters to you.
