Consult your OB-GYN first. We don’t have comprehensive safety data for pregnancy or breastfeeding, so the responsible answer is to defer to your obstetrician. If they approve, dosing stays standard.

Talk to your doctor before starting. Nattokinase has mild fibrinolytic (clot-breaking) properties. With warfarin specifically (narrow therapeutic window), your prescriber needs to weigh in. Low-dose aspirin is usually fine but the call belongs to your doctor.

Don’t stop your prescribed medication on your own.

Generally yes — PPIs and nattokinase work via different mechanisms. PPIs reduce acid production; nattokinase supports lining repair. Many of our long-term customers use both. But mention to your doctor at your next visit so they know.

Adults (18+). We don’t have pediatric safety data, and most gastric/GERD products are formulated for adult bodies. For teenagers experiencing recurring gastric, please consult a doctor — there’s often an underlying cause that warrants medical attention.

For elderly customers (65+) on multiple medications, please consult your doctor before adding any supplement.

Active ulcer: see a doctor first. Nattokinase doesn’t directly treat ulcers — that needs medical care (often antibiotics for H. pylori, plus PPIs). Once your doctor’s treatment is in progress, message us; many customers add Nattoflux after the acute treatment phase for ongoing maintenance.

Not yet. We’re Malaysia-only for now. International shipping involves customs, regulatory compliance for supplements, and we’d rather get the local experience right first before expanding. If you’re in Singapore and want it badly, message us — we may be able to arrange a one-off.

We send you a WhatsApp message with the tracking number once your order is dispatched. The tracking link goes to NinjaVan (or whichever courier is in use). You don’t need to log into anything or check the website.

WhatsApp us within 14 days of receiving your order. We refund. No forms. No “let me forward you to support.” No “send us a 30-day journal proving you used it correctly.”

We’d rather refund you than have you spread an unhappy review. The product works for most people, not all. We accept that.

1. Message us on WhatsApp (the number on the contact page)
2. Tell us your order number + that you’d like to refund
3. We refund within 2 working days, back to the original payment method

You don’t need to ship the product back (unless it’s still sealed/unopened — then we’ll arrange pickup). Used product, you can keep or throw out. The refund happens regardless.

No, not if you’ve already opened/used some of it. Just keep it (or dispose of it). We trust you on this. If you abuse the policy with repeated refund requests, we’ll politely decline future refunds — but for genuine cases, no return needed.
