Natto is a traditional Japanese dish produced by fermenting soya beans with a particular bacterium known as Bacillus subtilis. It offers a range of health benefits linked to its specific properties and its rich nutrient content. The fermentation process gives natto its characteristic texture and aroma, and changes its taste.
Nattokinase is one of the enzymes specific to natto, created during fermentation. It is a proteolytic enzyme, which means it can break down proteins. It is particularly known for its ability to break down fibrin, the substance that helps form blood clots. This can have important consequences for the heart and the circulatory system: nattokinase may help thin the blood, reducing the risk of heart disease and supporting heart health.
These components and their effects are the subject of a good deal of research and discussion, which underlines their potential as a natural supplement.
Some of the health benefits associated with natto
High in probiotics
Natto is rich in bacteria such as Bacillus subtilis, which help balance the microbial flora in the gut. This can support digestion and the immune system.
Natto is known for its wealth of probiotic cultures, which develop during the fermentation that is central to its production. These probiotics play an important role in maintaining the balance of microbial flora in the gastrointestinal tract. They support the absorption of nutrients, improve digestion and strengthen the immune system. That balance of good bacteria in the gut matters for immunity.
The ability of natto's probiotics to improve digestion can be useful for people with a sensitive stomach, or for anyone wanting to optimise their digestion. They may also help with digestive problems such as diarrhoea or constipation.
Rich in protein and vitamin K2
The proteins in natto are an important source of nutrients for building the body's tissues. Vitamin K2, also present in natto, matters for the health of bones and heart.
Natto is a source of high-quality plant protein providing the amino acids needed for growth and tissue health, which makes it a valuable source of nutrients especially for vegetarians and vegans.
Supports heart health
Vitamin K2 plays a role in regulating calcium metabolism in the body. One of its key actions is directing calcium from the bloodstream into the bones, where it is needed for density and strength. This protects the arteries from calcium deposits and can lower the risk of cardiovascular disease, including atherosclerosis and heart attack.
The exceptional concentration of vitamin K2 in natto makes it a valuable addition to the diet for heart health. It is important to note, though, that you should consult a health professional before changing your diet or adding new foods to it.

Antioxidant properties
Natto contains substances such as polyphenols and flavonoids, which have antioxidant properties and can help fight free radicals in the body.
Fighting free radicals. The antioxidants found in natto can reduce the harm caused by free radicals — unstable molecules that can damage cell structures and contribute to premature ageing and the development of various diseases.
Health benefits. Dietary antioxidants such as those in natto are associated with improved immune function, support skin health and may have anti-inflammatory effects.
Natto can be a valuable source of antioxidants, which play an important role in fighting free radicals and maintaining the health of cells and organs. Including it in a balanced and varied diet can contribute to general health and wellbeing.
Supports digestion and detoxification
Fermenting the soya beans improves digestibility and can support the body's detoxification.
Fermentation and digestion. The fermentation process breaks down complex nutrients, which can make the food easier for the body to absorb. This can help people with a sensitive stomach take in certain nutrients more easily.
Detoxification and cleansing. Fermentation can also help remove toxins from the body more effectively, by supporting the processes through which the body clears unnecessary or harmful compounds.
Hawthorn, pomegranate and grape
Additional ingredients in the New Era Natto supplement include hawthorn, pomegranate and grape. Hawthorn is known for its cardioprotective properties and its ability to support heart health. Pomegranate and grape are sources of antioxidants with a favourable effect on the circulatory system and immune function.
Although natto supplements may have these beneficial effects on digestion and detoxification, it is important to remember that every body reacts differently. Consulting a health professional is always advisable.
Natto may be unsuitable for people with certain allergies or health conditions.
