FAQ
Questions about DUO KINASE
Answers for shoppers considering Natto.
How do I take DUO KINASE each day?
Take 2 enteric-coated capsules together first thing in the morning, on an empty stomach, at least 30 minutes before eating. Swallow whole with water. Don't chew or open them, the coating protects the enzymes.
Why does the coating matter for these enzymes?
Stomach acid destroys unprotected fibrinolytic enzymes. Every DUO KINASE capsule is enteric-coated so lumbrokinase and nattokinase survive the stomach intact and reach the intestine where they're actually active.
How is this different from a single-enzyme nattokinase bottle?
Most bottles give you one enzyme, often at a token dose. DUO KINASE pairs full-dose lumbrokinase (20mg) and nattokinase (2000 FU) plus vessel-support botanicals, all enteric-coated, in one daily capsule instead of two.
Does this replace aspirin or fish oil supplements?
No. This isn't a treatment for any disease. Aspirin targets platelets; fish oil is omega-3 focused. DUO KINASE is a daily fibrinolytic-enzyme habit for circulation, positioned differently, not as a medical substitute.
What's in DUO KINASE besides the two enzymes?
Serrapeptase and bromelain support proteolytic activity; rutin, diosmin-hesperidin, horse chestnut, grape seed extract, and butcher's broom support vessel walls and heavy legs; vitamin K2 (MK-7) rounds out the formula.
Can I pause or cancel my subscription anytime?
Yes. Subscriptions can be paused or cancelled anytime, no long-term commitment required. Renewals simply return to your selected tier's base pricing, and you stay in control of when bottles ship.
How long does one bottle of DUO KINASE last?
Each bottle holds 60 enteric-coated vegetarian capsules, a 30-day supply at 2 capsules daily. The 90-day subscription ships three bottles together, so you're covered for a full quarter without reordering.
Do the capsules smell or taste like natto?
No. These are odourless, clean vegetarian capsules with a smooth, glossy shell, none of fresh natto's pungent smell or stringy texture. Just swallow whole with water, no fermented taste at all.
What does limited tracking mean?
Limited tracking means the tracking page may show only major checkpoints instead of every carrier handoff. Updates can pause between scans, especially while a parcel is moving between facilities or being transferred for local delivery. You may sometimes see extra detail on external parcel-tracking websites by entering the same tracking number. Free shipping options with limited tracking can take up to 30 days.
