This **Serrapeptase** capsule delivers 40,000 SPU, landing right at the low end of the range used in clinical trials for reducing post-surgical swelling and easing sinus congestion. Most studies dose around 60,000 SPU daily, so one capsule covers the minimum — you'd take two to sit mid-range.
It comes enteric-coated, which matters: this enzyme is destroyed by stomach acid without that protection, so the coating plus the label's empty-stomach instruction are what let it actually reach your system.
The evidence is genuine but limited. A handful of mostly small, older RCTs point to reduced edema and thinner mucus, so treat the benefits as plausible rather than established — and skip it if you're on blood thinners, since the label flags that interaction.
