Gluthic vs Nutri Collagen: Which Skin Supplement Is Worth It in Pakistan 2026?
Gluthic vs Nutri Collagen compared: what is actually in the tablet and the capsules, and which skin supplement suits you better in Pakistan.
Your body's own collagen production starts slowing from around the age of 25, which is what Nutrifactor and the other collagen brands we stock say on their own product pages. That is roughly when two supplements start showing up in every skin conversation in Pakistan: glutathione and collagen.
Both promise glowing, firmer, younger-looking skin. Both cost real money. They do completely different things.
Depending on your actual skin concern, one will serve you far better than the other. This guide compares the two most asked-about options on our shelves. Gluthic (NB Sons' glutathione tablet) and Nutri Collagen (Nutrifactor's collagen capsule). So you can decide with facts, not guesswork.

Short answer: Want brighter, more even skin tone? Go with Gluthic. Want to work on fine lines, dryness and hair and nails? Nutri Collagen is your pick. Plenty of women in Pakistan take both, and we will explain why below.
What Is Gluthic?
Gluthic is NB Sons' skin brightening and anti-aging tablet, and we sell it here at Yellow Pink. One tablet carries L-glutathione 500 mg with vitamin C 50 mg, and the directions are one tablet daily with water. Glutathione is a tripeptide your body makes itself, and it is central to how cells defend themselves against oxidative stress.
Glutathione does not bleach skin. In the randomised trial on oral glutathione published in Clinical, Cosmetic and Investigational Dermatology, the researchers describe it pushing melanin synthesis toward lighter pheomelanin rather than darker eumelanin, and disrupting the way tyrosinase and tyrosinase-related protein 1 are moved around inside pigment cells. It works with your own pigmentation process, so changes are gradual and look natural rather than patchy.
That same trial is the honest evidence base. Healthy adults took 250 mg a day of reduced or oxidised glutathione, or a placebo, for 12 weeks. Melanin index and UV spots trended lower than placebo, wrinkles improved significantly at some sites, and elasticity tended to improve, though not every measurement reached statistical significance and the group was small. Promising, not settled.
The vitamin C in Gluthic earns its place. MedlinePlus lists vitamin C as what your body uses to form collagen and as an antioxidant that blocks some of the damage free radicals do. At 50 mg per tablet it is a top-up rather than your whole day's requirement, which MedlinePlus puts at 75 mg a day for women aged 19 and over.
Gluthic Key Benefits
- Radiant, brighter-looking skin and a more even tone
- Antioxidant defence against pollution and everyday stress
- Skin elasticity, firmness and moisture retention
- Less obvious dullness, fine lines and rough texture
- Supports the liver's natural detoxification process
- Vitamin C, which your body needs to form collagen
What Is Nutri Collagen?
Nutrifactor's Nutri Collagen is one of the most recognisable collagen supplements in Pakistan, and it is a capsule, not a powder. A bottle holds 60 capsules. A 2-capsule serving gives collagen types 1 and 3 500 mg, vitamin C 10 mg and biotin 833 mcg. Nutrifactor's directions are 2 to 4 capsules daily on an empty stomach, at least 30 minutes before a meal.
Glutathione works on pigment. Collagen works on structure. Types 1 and 3 are the forms that make up most of the collagen in skin and connective tissue, and vitamin C is included because your body cannot build collagen without it. Biotin is there for hair and nails.
Now the part most collagen articles skip. Cleveland Clinic's dermatologists say a few small studies have shown limited improvement in skin texture, that many of those studies were funded by manufacturers, and that most collagen you swallow is broken down by digestion before much of it could reach skin. They put the timeline at three to six months, if results appear at all. Nutri Collagen is a reasonable thing to try. It is not a proven fix, and any brand telling you otherwise is selling.
If you would rather have a powder to stir into a drink, we stock two: Nutrifactor Collagatin Powder at 6000 mg of marine collagen types 1 and 3 per sachet, 30 sachets to a box, and VERSUS Marine Collagen at 10 g per sachet from North Atlantic cod, 24 sachets to a box.
Nutri Collagen Key Benefits
What Nutrifactor says it supports:
- Smoother, better hydrated skin
- Stronger hair and less breakage
- Stronger nails
- Bones, joints, tendons and ligaments as natural collagen production slows
- Vitamin C and biotin alongside the collagen itself
Composition Comparison: What is Actually Inside?
| Ingredient | Gluthic (per tablet) | Nutri Collagen (per 2-capsule serving) |
|---|---|---|
| Glutathione | 500 mg (L-glutathione) | Not present |
| Collagen types 1 and 3 | Not present | 500 mg |
| Vitamin C | 50 mg | 10 mg |
| Biotin | Not present | 833 mcg |
| Form | Tablet | Capsule, 60 per bottle |
| Daily dose | 1 tablet | 2 to 4 capsules |
The core distinction is simple. Gluthic works on melanin and antioxidant defence. Nutri Collagen supplies structural protein and the nutrients that go with it. Different pathways, different outcomes, so the right choice depends entirely on what your skin actually needs.
One number worth noticing if quantity matters to you: a Nutri Collagen serving carries 500 mg of collagen, while a Collagatin sachet carries 6000 mg. The capsules are the low-dose option, the powders are the higher dose.
Skin Brightening vs Anti-Aging: Understanding the Real Difference
This is the most important distinction. Pakistani women often mix up these two concerns, or assume one product handles both.
Glutathione (Gluthic) Works Best for:
- Dull, uneven skin tone, the concern most brightening supplements are actually bought for
- Hyperpigmentation and dark spots, from sun damage, acne marks or melasma
- Oxidative stress, since urban air and strong sun both add to the load your skin deals with daily
- Overall skin radiance, that lit-from-within look
Collagen (Nutri Collagen) Works Best for:
- Fine lines, particularly around eyes, forehead and smile lines
- Skin that feels less firm than it used to
- Dry skin, where better hydration is what Nutrifactor claims for it
- Hair and nail concerns, helped along by the biotin in the capsule
- Joint comfort, often the secondary benefit that surprises people
Take a woman in her late 20s with uneven tone from sun and acne marks. She will get more out of Gluthic. Now take a woman in her late 30s whose skin is not bouncing back, with fine lines forming and hair that breaks. Nutri Collagen is the better fit for her, with realistic expectations attached.
How Long Until You See Results?
This question matters more in Pakistan than people admit. Supplements get abandoned when results do not appear fast enough.
Gluthic (Glutathione): the trial above ran for 12 weeks before measuring, and that is the timeframe to plan for. Pigment changes are slow by nature, and how fast you see anything depends on your starting tone, your sun exposure and whether you actually wear sunscreen. Skip the SPF and you undo the work every single day.
Nutri Collagen: Nutrifactor's own directions say to give it 8 to 12 weeks of consistent use because collagen results build gradually. Cleveland Clinic is more cautious still and puts it at three to six months, if anything shows at all. Either way, a two-week trial tells you nothing.
Can You Take Gluthic and Collagen Together?
Yes. For women in their 30s and above, taking both makes sense. They work on different things without overlapping:
- Gluthic handles tone and antioxidant defence, brightness and evenness
- Collagen handles the structural side, firmness, hydration, hair and nails
The vitamin C in both is nowhere near excessive. A Gluthic tablet has 50 mg and a 2-capsule Nutri Collagen serving has 10 mg, so together that is 60 mg, still under the 75 mg a day MedlinePlus lists for adult women. Since vitamin C is what the body uses to form collagen in the first place, having it in both products is helpful rather than wasteful.
If budget is a concern, which it often is, prioritise your most pressing concern. Tone and radiance, or firmness and fine lines.

Both prices above are pulled live from our product pages, so what you see is what the product costs today rather than what it cost when this guide was written. Compare them as you read them, and remember they buy different things: a tablet aimed at tone, and capsules aimed at structure. If you want the higher collagen dose instead, Collagatin Powder is Rs 4,800.
Who Should Choose Gluthic?
- Women dealing with uneven skin tone, dullness or hyperpigmentation
- Anyone with post-acne dark marks or sun spots
- People who spend a lot of time outdoors in Pakistani sun, and who wear sunscreen
- Those who want antioxidant and liver support alongside the skin benefit
- Women under 30 focused on brightening rather than anti-aging
- Anyone who prefers one tablet a day to a handful of capsules
Who Should Choose Nutri Collagen?
- Women in their 30s and 40s noticing changes in firmness
- Anyone with early fine lines or crow's feet
- People with dry skin that lacks plumpness
- Women also dealing with hair breakage or weak nails
- Anyone with joint discomfort who wants a dual-purpose supplement
- Anyone who wants to try collagen in capsule form before committing to a powder
The Verdict: Gluthic vs Nutri Collagen
These are not really competing products. They answer different questions, and the "vs" framing is a little misleading. Here is a better way to think about it:
- Choose Gluthic if your main goal is brighter, more even tone and antioxidant protection, and you are willing to wear sunscreen daily to make it count.
- Choose Nutri Collagen if your main goal is smoother skin, firmness, hair and nails, and you are happy to try something the evidence supports loosely rather than strongly.
- Use both if you want to cover tone and structure at once and the budget allows.
What makes Gluthic the more interesting one for readers here is the local context. Strong sun and urban air are a daily fact of life in Pakistan, and glutathione is aimed squarely at the pigment and oxidative side of that. Nutri Collagen goes after the structural decline that sets in from around the age of 25. Whichever you pick, sunscreen and sleep do more for your skin than any capsule will.
Ready to start? Gluthic at Rs 3,500 is the pick for tone and brightness, and Nutri Collagen at Rs 1,420 is the low-commitment way to try collagen. Both sit in Women's Health with the rest of our skin supplements. We deliver across Pakistan with cash on delivery, and delivery is free on orders over Rs 5,000 in Punjab.

Shop Gluthic Glutathione →Frequently asked questions
Is glutathione or collagen better for skin whitening in Pakistan?
Glutathione is the one aimed at pigment. The published trial on oral glutathione measured melanin index and UV spots and found both trending lower than placebo over 12 weeks. Collagen does not act on pigment at all, so for tone and brightness specifically, glutathione is the targeted choice. Neither is a bleaching agent, and neither will change your natural skin colour.
Can I take Gluthic and Nutri Collagen at the same time?
Yes. They work through different routes, melanin regulation on one side and structural protein on the other, and there is no known interaction between them. Take each as directed on its own pack: one Gluthic tablet with water, and Nutri Collagen capsules on an empty stomach at least 30 minutes before a meal.
How long should I take these supplements before seeing results?
Plan on 12 weeks for Gluthic, which is how long the published glutathione trial ran before measuring skin. For Nutri Collagen, Nutrifactor says 8 to 12 weeks and Cleveland Clinic says three to six months, if results come at all. Both need consistent daily use. Skipping doses slows progress noticeably.
Do I need to use sunscreen with these supplements?
Yes, especially with Gluthic. If you expose skin to UV without protection, you are triggering melanin at the exact moment you are trying to reduce it. The NHS advises at least SPF 30 with at least 4-star UVA protection, applied to the face, neck and ears and reapplied every two hours and after sweating or swimming. Sunscreen alone is not enough either, so use shade and clothing with it.
Are there any side effects from Gluthic or Nutri Collagen?
Both are well tolerated by most people. In the 12-week glutathione trial the researchers reported good tolerability and no serious adverse events at 250 mg a day. Cleveland Clinic lists headaches, lightheadedness or diarrhoea as possible with collagen supplements, usually mild. If you have an underlying health condition, or are pregnant or breastfeeding, speak to a doctor before starting either one.
