Short answer: ingredients affecting blood flow and clotting — including nattokinase and nitric-oxide precursors — are a specific caution before any planned surgery, and should be disclosed to your surgical team in advance.
Why blood-flow effects matter around a procedure
Ingredients affecting circulation and clotting can influence bleeding risk and blood pressure stability during and after surgery — relevant information for anesthesia and surgical planning that shouldn't be left undisclosed.
What to tell your surgical team
- The full ingredient list of any supplement you're taking
- How recently and consistently you've been taking it
- Any other medications, including over-the-counter ones
⚠️ Worth knowing: if you have planned surgery, ask a doctor about pausing this type of supplement in advance — this is a targeted, time-bound precaution, not a permanent restriction.
Why disclosure matters more than guessing
Surgical teams routinely review supplement lists and can advise on appropriate timing far more reliably than general guidance — always disclose, rather than assuming a "natural" supplement is automatically fine to continue.
