Improved toilet frequency
It aids in alleviating constipation and activates my sluggish stomach. I find myself rushing to the loo daily, which reflects its effectiveness. Drinking plenty of water is essential. The quality is high, and the pills are an average size, convenient to swallow.

Although nattokinase is excellent for blood circulation, if you have a soybean allergy or irritable bowel syndrome, it may worsen abdominal bloating. Consequently, constipation persists, making it difficult to pass stool.

Maintained constipation relief

I previously took nattokinase as a supplement for constipation in Japan and found it effective but expensive. After discovering it on iHerb, I bought it straight away. I switched from 2 tablets at night to 1 tablet in the morning and evening. The effect is adequate, and I wish to continue as is, having placed another order immediately.
