How Much Natto Safe to Eat Daily?

how much natto should I eat daily

Natto is considered a main dish in Japan because of its high protein content.

It is also high in calories and purine: about 80 kcal and 46 mg per pack (40 grams). 

As the daily intake of purine should be less than 400 mg, eating the food a lot constantly can increase your weight and cause gout. 

Natto is also a rich source of vitamin K, which helps in the clotting of blood. If you are taking medicines like warfarin, be cautious.


Given the conditions above, the recommended daily consumption of natto is one or two packs.

      Hi, Thank you for commenting!
      For your information from my side, 日本ナットウキナーゼ協会 or Japan Nattokinase Association says the recommended intake of Nattokinase is 2000FU a day, which means you have to take 1 or 2 packs of Natto to meet that criterion because one pack (about 50 grams) of Natto contains 1500FU of Nattokinase on average. If you want to take more in a day, it would be better to have supplements.
