FAQ about Natto capsules

When should I take the capsules?

The natto powder inside the capsules is 100% pure natto. You can take them at any time, but it is better to set a fixed time to prevent forgetting to take them. Many users prefer taking them after dinner or before going to bed.

What is the best way to take the capsules?

You can take the capsules with cold or lukewarm water, before or after meals. We recommend setting a fixed time to prevent forgetting to take them
We recommend a daily intake of 3 capsules at a fixed time.

How long does it take to feel results?

Every person has differences in diet, lifestyle, physical condition, constitution, Etc., This fact makes it difficult to specify a time for noticeable results. The essential factor for obtaining results is taking the product every day.

The recommended dosage is three capsules per day. Is it better to take them separately in the morning, noon, and evening? Is it better to take all at once at a specific time?

As long as you are taking three capsules per day, any time is acceptable. Taking them separately or together does not affect the product effectiveness or potency. However, splitting the time makes it easy to forget, and the most important is continuity. Taking three capsules before dinner seems to be easy to remember for most users.

I am taking medicine. Can I use the product?

Please consult with your family physician before using our products if you are on medication, undergo illness treatment, or take anticoagulants (warfarin, Etc.). People who are forbidden to eat natto due to medical reasons must also consult.

Can I take dietary supplements during pregnancy or breastfeeding?

We suggest taking a break from health supplements during pregnancy and lactation. It is a delicate time for your body. Keep a healthy diet under the supervision of your family physician.

What is the difference between natto powder capsules and nattokinase supplements?

The freeze-dried powder in our capsules is whole natto. It contains all natto nutrients and an increased quantity of probiotics.
Nattokinase is a proteolytic enzyme produced by Bacillus natto during the natto fermentation process. Nattokinase supplements only contain this enzyme. Our product includes all nato nutrients, including nattokinase.

Does sonomono natto capsules contain nattokinase? How many milligrams per capsule?

Nattokinase is a product of soy fermentation into natto. Our capsules contain pure natto powder with all its nutrients, including nattokinase.
The nattokinase enzymatic activity of sonomono natto powder is 98FU / g. It is certified by The Japan Food Research Laboratories. However, be aware that this content may vary.

I heard that Vitamin K worsens blood circulation? Is it true?

This misunderstanding seems to have arisen from the common instruction of refraining to eat natto when taking the anticoagulant warfarin.

There are different types of medicines that make blood smooth. One of them, warfarin, has a similar molecular structure to vitamin K contained in natto, for this reason, taking both at the same time may weaken the efficiency of warfarin.

The truth is that vitamin K by itself does not worsen circulation.

Is it harmful to take too much natto bacteria?

Bacillus subtilis, the bacteria responsible for turning soy into natto, is a probiotic or beneficial bacteria. This resilient microorganism can survive in environments of -100 to 100 degrees for 10 minutes or more. The B. subtilis spore confers protection to gastric acid, allowing it to reach the intestines alive. B. subtilis support other good bacteria such as lactic acid bacteria and bifidobacteria and help to reduce harmful intestinal bacteria.
Even if you ingest significant quantities of Bacillus subtilis, it will leave the intestines with the stool after completing its life cycle. Therefore, there is no need to worry about over intake.
We recommend adjusting the natto powder capsules intake daily according to your physical condition.

I hear that there are genetically engineered natto bacteria. Are the bacteria of your products a GMO or natural?

Our company has zero tolerance for GMOs usage. We use natural natto bacteria in all our products, managed by a long-established natto shop that has been in business for more than 60 years.

I hear that taking too much soy isoflavones is not good, but is that okay?

According to national guidelines, *soy isoflavones’ safe upper limit intake is 30 mg per day.
*Soy isoflavone aglycone equivalent.
According to a Japan Food Research Laboratories survey, natto soy isoflavone content is 0.54 mg per 0.42 g of each grain.
Even taking three tablets per day, the amount of soy isoflavone is 1.62 mg, within the standard value.
* Note: The national guideline provides guidelines regarding soy isoflavones content of “food for specified health use.” However, sonomono natto is not a “food for specified health use.” Please, use this information just as a reference.

Natto is said to contain high quantities of purines. Is it true?

We have never analyzed the purines content of our natto powder.
According to several sources, the raw natto average purines content is 113.9 mg / 100 g.
The Hyperuricemia / Gout Treatment Guidelines provide guidelines for assessing food purines as high or low using a 100g sample as reference.
Purines content per 100g of food
300 mg or more – extremely high
200-300mg – high
50-100mg – low
50 mg or less- very low

Raw natto purines content is 113.9mg / 100g. According to the table, it is classified as a “low purines content food.”
According to this information, the estimated purine content of 3 capsules of natto powder (1.26g) is considered “very low.”

What is the material of the capsules?

We use plant-derived capsules made of hydroxypropyl methylcellulose (HPMC). It is a plant-derived food additive that is widely recognized worldwide as safe. HPMC is a tasteless and odorless substance made from cellulose, the main component of plant fiber.
(The capsules contain soy lecithin, regarded as an allergen for some people)

What is the capsule size?

We use No. 1 size capsules. Approximate dimensions 20 mm x 7 mm.

Where are the soybeans used as raw material produced?

We use chemicals-free cultivated soybeans from Kohoku Town, Saga Prefecture, Kyushu. We use “Fukuyutaka,” a rare domestic variety suited for natto production due to its plumpness and good quality.
* The soybean production area may change due to natural disasters.

FAQ about Natto powder

There are two types of natto powder: normal and mild. What is the difference?

There is no significant difference in the nutrients and amount of natto bacteria. The mild version has less smell and viscosity because we use a different bacteria strain.
We recommend “natto powder normal” (navy blue label) to people who enjoy natto aroma and flavor. Natto powder mild (light blue label) is better for people who want a less potent natto aroma product. Choose according to your preferences.

I want to use natto powder for baby food. What is the recommended dosage?

Sonomono natto powder is freeze-dried pure natto, free of additives and fillers. You can use it as normal natto. Typically, parents start to include natto in baby food when the baby is around 7 to 8 months old.

We recommend starting with 1/3 or 1/4 teaspoon of natto powder and check the situation.
Many people use natto powder directly on baby food. However, it may be better to mix it with soup or side dishes and cook it.

The content of natto bacteria in your product seems to be very high. Am I not overdosing by eating it daily?

One spoon of natto powder contains the equivalent of probiotics amount of ten packages of raw natto. The amount is large, but these bacteria are a nutritional component of natto. You can use natto powder with peace of mind. Other commercially available intestinal regulators contain the same amount of natto bacteria. 。

What is the best way to store the natto powder after opening the bag? How long does it last after opening?

Food deteriorates quickly at contact with oxygen and humidity. For this reason, we recommend consuming our products as possible after opening, keep the bag tightly sealed, and carefully check moisture absorption.
You can also put the powder in a refillable bottle or airtight container.
If the environment is not humid, you can store the powder at room temperature. However, it is more stable if you preserve it in the refrigerator.

What kind of manufacturing method is freeze-drying?

It is a method that uses ultralow temperature and vacuum for removing moisture from food.
The loss of moisture in food prevents the growth of microorganisms, helping its preservation.
Also, unlike high heat drying, freeze-drying preserves food nutrients and flavor. You can enjoy natto flavor, aroma, and nutrients in all our products.

What are the nutritional components of sonomono natto powder?

Sonomono natto powder is 100% pure natto. We do not mix it with soybean powder or other ingredients. Therefore, our powder contains all natto nutrients and increased probiotics amount.

You can check the detailed nutritional information on the following link.

Do the bacteria of sonomono natto powder die in contact with hot water? Can I add it to hot miso soup?

The bacteria of our natto powder is in spore form. A “spore” is like a “barrier” created by Bacillus natto to protect itself from a harsh environment. The spore allows the bacteria to survive 100 °C temperatures and the gastric acid.

Raw natto has a strong smell and stickiness. What about sonomono natto powder?

Sonomono natto powder has a unique scent but not as strong as raw natto. If you mind natto aroma, we recommend buying our mild type that has reduced smell and stickiness.
The powder itself is not sticky, but it becomes tacky when you combine it with other ingredients.
We recommend purchasing our natto capsules for people who want to avoid natto aroma and stickiness.

What are non-GMO soybeans?

GMO stands for a genetically modified organism. A genetically modified soybean is a soybean that has had DNA introduced into it using genetic engineering techniques.
Japan imports more than 90% of soybeans from the United States and China, primarily GMOs. Those GMOs soybeans are modified to stand high doses of herbicides and pesticides, increasing the risk of carrying toxins and carcinogens into our bodies.
We consider that natural soybeans, cultivated without chemicals, are the best option for supporting health. For this reason, we solely use non-GMOs soybeans in all our products. The variety of our soybeans is Fukuyutaka, cultivated in Saga Prefecture, a region famous for its pristine air, clean water, and delicious agricultural products.
* The soybean production area may change due to the effects of disasters.

I’m taking warfarin, and my doctor forbade me to consume natto. Can I eat sonomono natto powder?

Natto contains vitamin k that weakens anticoagulants action, such as warfarin. Please be sure to consult your doctor before using our products. For reference, a teaspoon (1.5g) of natto powder contains approximately 30 μg of vitamin K.

What is the protein content of natto powder?

Amino acids (proteins) account for 42% of the constituents of natto powder. Each teaspoon (1.5g) contains approximately 0.63g of protein.
Raw soybeans have an amino acid score of 100. It makes protein content similar to pork meat, chicken, and tuna.
The fermentation process of soy into natto improves the bioavailability of the nutrients. Compared to soy, the nutrients of natto are easier to absorb by our body. For this reason, natto powder can be considered a high-quality protein source.

I heard it’s not good to heat natto. What about natto powder? Can I sprinkle it on warm rice or heat it?

There is no problem with sprinkling natto powder on hot rice and eating it.
The reason for recommending not to heat natto or put on hot rice is because the heat destroys the nattokinase enzyme.
Enzymes are sensitive to heat, and nattokinase disappears when heated at 65 ° C for 1 hour.
However, Bacillus subtilis (natto probiotics) and vitamins are affected at all. In general, cooking destroys some nutritional components of any food.
In the case of regular natto and natto powder, it is better not to heat them if you do not want to destroy the nattokinase. However, natto powder preserves other nutrients even if heated. In general, you do not need to worry about the loss of nutrients due to cooking.

Why is brown sugar low calory?

Calories depend on the amount of protein, fat, and carbohydrates. In particular, the amount of fat affects the total calories. The formula for calculating calories is {(protein + carbohydrate) x 4} + {(lipid) x 9}. Therefore, there will be some differences depending on the product.

In the case of brown sugar snacks, the water content is a little bit higher than the others, it makes look nutritional component and calories content lower. However, in terms of sugar comparison, the brown sugar snack has the highest amount of carbohydrates. The sea salt snack contains sunflower oil, making it to be the highest in calories.

FAQ about Mulberry tea

Why is it difficult to dissolve the tea in hot or cold water? It also precipitates after some time.

For crafting our tea, we powder the whole tea leaves. This process creates a powder of big particles that trends to settle. It is possible to make a powder that dissolves quickly by removing the leaves’ dietary fiber, but it will also remove essential nutrients.
We prefer to keep all nutrients even if it somehow affects the solubility.
We recommend mixing vigorously with a spoon and drinking the tea immediately for the tea to dissolve evenly.

What is the DNJ content?

The DNJ content per a 50g bag of mulberry leaf tea is about 0.1g.
(Source: Japan Food Research Laboratories)

Is your tea organic JAS certified?

Although the product is not organic JAS certified, a soil specialist cultivates the mulberry plants without pesticides or chemical fertilizers.
