A: Please do not drink it because it is a natto starter specially made for natto making.

A: Maybe the fermentation process did not go well. Ferment it for about 12 more hours.

A: Let it sit in the refrigerator overnight after the warming process. Fermentation will stop, and the odor of ammonia can be alleviated.

**Q: Is it okay to eat natto everyday?**
