We recommend sticking to exactly 2 gummies daily. The formula is calibrated at this dose — exceeding it won't speed up results and is not recommended. Consistency over time matters far more than quantity.

No — morning or evening both work. What matters most is taking them at the same time every day. Picking a consistent time (with breakfast, after brushing teeth, before bed) dramatically improves compliance and results.

Yes — this is completely normal. Glutathione works cumulatively. Measurable melanin changes begin around week 2, but visible changes typically become noticeable between weeks 6-8. The 90% brightening figure from clinical trials is measured at 8 weeks. Keep going — quitting at week 3 is the most common reason people don't see full results.

Generally yes. ZINQ already contains Vitamin C, Vitamin E, B12, and Folic Acid — so avoid doubling up on high doses of these from other supplements without checking with your doctor. ZINQ pairs well with collagen drinks, iron supplements, and most skincare routines. If you're on prescription medication, consult your physician first.

Consult your physician before taking ZINQ if you are pregnant or breastfeeding. While the individual ingredients are found in food, the concentrated doses in ZINQ have not been clinically studied in pregnant or nursing populations. Your doctor can advise on what's appropriate for your situation.

ZINQ can be taken with or without food. Some customers prefer taking it after a meal to avoid any mild stomach sensitivity, though this is uncommon. Taking it with 250–300ml of water is recommended regardless.

Glutathione levels will gradually return to baseline when supplementation stops, and melanin production will resume at its natural rate. Results are maintained with continued use. Think of it like SPF — it works while you're using it. Many customers take ZINQ continuously for sustained effects.

Absolutely — ZINQ works from the inside and is designed to complement topical skincare, not replace it. It pairs especially well with SPF, niacinamide serums, and vitamin C topicals. Customers who combine ZINQ with a consistent skincare routine generally see faster and more pronounced results.
