Orders & delivery
Where does GUKIN deliver?
We ship across Pakistan and the UAE from local fulfilment, and internationally to most other markets. Domestic Pakistan orders reach Karachi, Lahore and Islamabad in 1–3 working days and other cities in 2–5. UAE orders arrive next day in Dubai, Abu Dhabi and Sharjah when placed before 4pm GST.
Is delivery free?
Yes — delivery is complimentary on Pakistan orders over PKR 6,000 and UAE orders over AED 150. Below those thresholds a flat charge of PKR 250 or AED 20 applies. International rates are calculated at checkout before payment.
Do you offer cash on delivery?
Cash on delivery is available throughout Pakistan on orders up to PKR 25,000. It is not offered in the UAE, where card and Apple Pay are the standard options. Prepaid orders are dispatched a day sooner on average.
How do I track my order?
A tracking link is sent by email and SMS the moment your parcel leaves our facility. If it has been more than 48 hours since you ordered and nothing has arrived, check your spam folder first, then write to us with your order number.
Can I change my delivery address after ordering?
If the order has not yet been dispatched, yes. Contact us within two hours of placing it and we will amend the label. Once a parcel is with the courier the address is fixed, though most couriers allow you to redirect it yourself using the tracking link.
Will I pay customs or import duty?
Orders within Pakistan and the UAE are shipped duty-paid, so nothing further is owed on arrival. For other destinations, any duty or local tax is set by your own customs authority and payable by the recipient. We declare all shipments accurately as dietary supplements.
How are the products packed for hot climates?
Every formulation is stability-tested to 40°C, and gummies ship in a foil-sealed jar with a desiccant to hold their texture through a Gulf or Sindh summer. If a jar arrives softened, leave it in the refrigerator for an hour — the actives are unaffected. If anything arrives damaged, we replace it.
Products & formulation
What makes GUKIN different from other supplements?
Most ranges treat gut, skin and energy as three separate shelves. GUKIN treats them as one pathway, because they share the same upstream mechanisms — barrier integrity, inflammation and cellular energy. Each formulation names its actives at full dose on the label, with no proprietary blends concealing how little of something is present.
Are the products halal?
Yes. Every GUKIN formulation is halal-certified and free of porcine gelatin and alcohol. The Biotin Gummies use pectin rather than gelatin, which also makes them suitable for vegetarians and vegans.
Where are the products manufactured and tested?
Manufacturing takes place in GMP-certified facilities, and every batch is third-party tested for identity, potency and heavy metals. The certificate of analysis for your batch is available on request — quote the batch number printed beside the expiry date.
Which product should I start with?
Start where the symptom is. Bloating, irregularity or reactive skin points to BIOME CLEANSE. Flat afternoons and slower recovery point to ENERGI. Hair, nails and skin texture point to the Biotin Gummies. The Find Your Ritual quiz on this page takes four questions and narrows it for you.
Can I take more than one formulation together?
They are designed to be stacked — the doses are set so that combinations stay within safe upper limits. The common pairing is BIOME CLEANSE in the morning with ENERGI, and RECOVER at night. Avoid doubling two products that both carry zinc without checking the totals.
Are there artificial sweeteners, colours or fillers?
No artificial colours and no synthetic sweeteners. The gummies are sweetened with a small amount of cane sugar and coloured with fruit and vegetable concentrate, which is why the shade varies slightly between batches. Capsules contain only what is needed to fill and stabilise them.
What is PDRN, and why is it in a skin formula?
PDRN is a polynucleotide fraction that signals fibroblasts to repair rather than merely hydrate. In practice it supports the wound-healing pathway that also governs everyday barrier turnover, which is why it sits alongside ceramides and hyaluronic acid rather than replacing them.
Is there gluten, dairy or soy in any product?
All formulations are free from gluten, dairy and soy. They are produced in facilities that also handle tree nuts, so we declare that risk for anyone with a severe allergy. The full allergen statement is printed on every carton.
How much creatine is in Clarity., and what form?
Five grams of creatine monohydrate per serving — the form and dose used in the published trials. Not a buffered, liquid or "advanced" variant: none of those have beaten monohydrate head to head, and all of them cost more.
How much sugar is in the Biotin Gummies?
Under two grams per gummy, in a pectin base rather than gelatin. They are sweetened to be edible daily, not to taste like confectionery, and there is no porcine gelatin or alcohol in the formula.
Does BIOME CLEANSE contain fragrance or essential oils?
No synthetic fragrance and no essential oils. The wild berry note comes from the bioferment itself. It is formulated for daily use on skin that reacts to most cleansers.
What is the NMN dose in Revive., and why is it paired with quercetin?
NMN alongside quercetin, CoQ10, resveratrol and B vitamins. Quercetin is included because it inhibits CD38, the enzyme that consumes NAD+ — raising the precursor while slowing its breakdown is more efficient than either alone.
Ageing & longevity
What is the difference between lifespan and healthspan?
Lifespan is how long you live. Healthspan is how long you live without meaningful decline in energy, mobility, cognition or appearance. Across most populations the gap between the two runs to more than a decade, and closing it is what the phrase functional longevity refers to.
At what age should I start?
Earlier is more useful than later, because these pathways compound. NAD+ begins declining in the late twenties and collagen synthesis slows from around twenty-five, so the late twenties to mid-thirties is the point of highest return. Starting at fifty is still worthwhile — the mechanisms remain responsive.
What is NAD+ and why does it matter?
NAD+ is the coenzyme that mitochondria use to turn food into usable energy, and that sirtuins and DNA repair enzymes need to function. Levels can fall by roughly half by mid-life. NMN is a precursor the body converts into NAD+, which is why it appears in ENERGI alongside trans-resveratrol.
How does gut health affect how I age?
A compromised intestinal barrier allows bacterial fragments into circulation, and the low-grade inflammation that follows accelerates almost every ageing pathway — collagen breakdown, insulin resistance and cognitive fog among them. Repairing the barrier removes the upstream cause rather than managing the symptoms.
Can supplements really slow ageing, or is that marketing?
No supplement stops ageing, and we will not claim otherwise. What the evidence supports is narrower and still useful: correcting a deficiency, restoring a declining precursor, or reducing chronic inflammation measurably changes how a body functions. Sleep, protein, resistance training and sun protection remain the largest levers. These formulations are built to support them, not to substitute for them.
Does inflammation show on the skin?
Frequently, and often first. Because skin renews roughly every twenty-seven days, it registers internal change faster than most tissue. Persistent redness, slower healing and a dull surface texture are common early signals, which is why we treat skin as a readout rather than a separate category.
What is neuroplasticity, and can I influence it?
Neuroplasticity is the brain's capacity to reorganise its connections in response to what you repeat. It depends on inputs you control: deep sleep for consolidation, omega-3 phospholipids for membrane building, and low chronic inflammation, which otherwise suppresses BDNF, the growth factor driving the process.
Does creatine actually help cognition, or is that marketing?
It helps in specific conditions. A 2018 systematic review of randomised trials found improved short-term memory and reasoning, but the effect concentrated in sleep-deprived subjects and in vegetarians, who start with lower brain stores. A rested omnivore should expect a modest effect at best.
How long before brain creatine stores are saturated?
Longer than muscle. Muscle saturates in three to four weeks on 3–5 g daily; transport across the blood-brain barrier is slower, which is why cognitive trials running under four weeks tend to find nothing. Give it six to eight weeks before judging.
Is neuroplasticity really trainable in adults?
Yes, though more slowly than in children. The reliable loop is focused attention on a genuinely difficult task, followed by adequate deep sleep to consolidate it. Aerobic exercise raises BDNF; chronic high cortisol works against all of it.
Usage & rituals
When should I take each formulation?
BIOME CLEANSE and ENERGI are morning products, taken with food. The Biotin Gummies can be taken at any point in the day. RECOVER belongs about an hour before bed, since magnesium glycinate and L-theanine work with sleep onset rather than against it.
How long before I notice a difference?
Digestive comfort and sleep quality usually shift within two weeks. Energy and focus tend to settle around weeks three to five. Skin and hair follow their own renewal cycle, so allow eight to twelve weeks — anything faster is hydration, not structural change.
Should I take them with or without food?
With food, as a rule. Fat-soluble vitamins need dietary fat to absorb, and taking zinc on an empty stomach is the most common cause of nausea. RECOVER is the exception and works equally well either way.
Can I take these during Ramadan?
Yes. Take the morning products with suhoor and the evening product after iftar, both alongside food. Hydration and electrolytes matter more than usual during long fasts, so RECOVER after iftar is the pairing most people find useful.
Do I need to cycle off, or can I take them continuously?
Continuous use is appropriate for the daily formulations. BIOME CLEANSE is often run as a focused eight to twelve week course and then reduced to a maintenance dose. There is no requirement to cycle off, though a short break every few months is a reasonable way to reassess what is actually helping.
What if I miss a day?
Resume the next day at the normal dose. Do not double up. These pathways respond to consistency across weeks, not to any single serving, so one missed day changes nothing.
Can I take these with prescription medication?
Speak to your doctor or pharmacist first, particularly if you take blood thinners, thyroid medication or antibiotics, where timing and interaction genuinely matter. Bring the label — every active and its dose is printed there, which makes the conversation straightforward.
Are they suitable during pregnancy or breastfeeding?
Not without medical supervision. Several actives, including NMN and trans-resveratrol, have not been studied sufficiently in pregnancy for us to recommend them. Consult your obstetrician before starting or continuing.
Is there an age limit?
The range is formulated for adults, eighteen and over. There is no upper limit; if anything, the recovery and cellular-energy formulations become more relevant with age.
Can I take Clarity. and Energize. together?
Yes. Creatine and NAD+ precursors act on different parts of the same energy system — one buffers ATP, the other supplies the cofactor that makes it. There is no known interaction. Take Clarity. at any consistent hour and Energize. in the morning.
Do I need to load creatine?
No. Loading with twenty grams a day for a week shortens the time to muscle saturation but is not necessary and causes more GI discomfort. Three to five grams daily reaches the same place in three to four weeks.
Should I cycle off any of the formulations?
Creatine, magnesium and the B vitamins do not require cycling. For NMN and NAD+ products some people prefer five days on, two off — there is no strong evidence either way, and consistency matters more than the schedule.
Will the gummies or capsules survive a Karachi or Dubai summer?
Gummies are the vulnerable one — above roughly 30°C they soften and can fuse. We ship them with an insulated liner in summer months. Store all products below 25°C, away from direct light, and keep the gummies in a cupboard rather than a car.
Payment, returns & care
Which payment methods do you accept?
Visa, Mastercard and American Express, plus Apple Pay and Google Pay. In Pakistan we also accept bank transfer, Easypaisa, JazzCash and cash on delivery. In the UAE, Tabby is available for instalments. Prices are charged in PKR, AED or USD depending on your location.
What is your returns policy?
Unopened products can be returned within thirty days of delivery for a full refund. For reasons of safety we cannot resell opened supplements, but if a product does not suit you, write to us — we would rather resolve it than have you finish something that is not working.
My order arrived damaged or incomplete.
Send a photograph and your order number within seventy-two hours of delivery and we will dispatch a replacement immediately. There is no need to return the damaged item.
How should I store the products?
Somewhere cool, dry and out of direct sunlight, with the lid closed and the desiccant left in the jar. A bathroom shelf is the worst option in a humid climate; a bedroom drawer is better. Refrigeration is optional and helps gummies hold their texture in summer.
Can I subscribe and save?
A monthly subscription saves fifteen per cent, includes free delivery at any order value, and can be paused, rescheduled or cancelled at any time without contacting us. Given that most results depend on eight to twelve weeks of consistency, it is the more sensible way to buy.
Do you sell wholesale or to clinics?
We work with a small number of clinics, pharmacies and retailers across Pakistan, the UAE and Saudi Arabia. Write to us with your business details and territory and our team will send terms.
What happens if the gummies arrive melted or fused?
Send us a photograph within 48 hours of delivery and we replace the jar, no return required. Heat damage in transit is on us, not on you.
Can I return a product I have already opened?
Unopened items can be returned within thirty days for a full refund. For an opened product, if it disagreed with you or arrived faulty, write to us — we handle those case by case rather than by policy, and we have not yet refused a reasonable one.
