Worsened tinnitus
32 people found this helpful
Unfortunately, this product worsened my tinnitus. Each time I attempted to use it, my symptoms intensified. After three trials, I can confidently say it exacerbated my condition. However, I continue to appreciate other products from Doctor's Best and the service from iHerb, which I've used for eight years.

Improved blood supply
After Covid, I experienced issues with my blood vessels and began taking Nattokinase daily on an empty stomach. Within 10 days, I noticed visual improvements in my veins. Three weeks in, the blood supply to my limbs improved, and their chilliness reduced. Furthermore, my tinnitus has significantly decreased.

Reduced tinnitus effects
I took this medication alongside Ginkgo Biloba, and I believe my tinnitus has lessened. I no longer experience dizziness, and my blood pressure has normalised to around 120 over 80, rarely rising above 140.
