Can you drink natto starter as a supplement?

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

Can you use natto as a starter?

Store-brought natto has a weaker bacteria power than natto starter. Please use this natto starter with higher bacteria power and quality. A small package goes a long way.

Why is my natto doesn’t have the sticky string?

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

Why does my natto smell like ammonia?

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

Is it okay to eat natto everyday?

Natto is high in protein, fiber, minerals, Vitamin K, Vitamin C, etc. Please eat one serving of natto (150g/5.3oz) per day to get its nutrition and health benefits.
