Effective for cough
I absolutely LOVE this product! I found it by chance from a woman on a plane who studies the brain. I have a chronic cough that doctors haven't been able to alleviate much, but this has made a significant difference! Additionally, I have had nerve issues since childhood, and those have improved as well. I've only been taking Natto Serra for two weeks, but I cannot express how much I appreciate it. There are no side effects, which is fantastic. I think the pharmaceutical companies don't want this getting out, but I'm spreading the word to anyone in need.

Cough relief
During COVID, I took it on an empty stomach each morning, and fortunately, I didn’t get ill. My entire family did the same, and my grandmother's cough, which had tormented her for three years, disappeared.

Frequently Asked Questions

Coughing is a reflex action that helps clear the airways of mucus, irritants, or foreign particles. It is a natural mechanism the body uses to protect itself and can be triggered by various factors, including infections, allergies, or environmental irritants. There are two main types of coughs: acute coughs, which typically last less than three weeks and often result from a cold or respiratory infection, and chronic coughs, which persist for more than eight weeks and may indicate a more serious underlying condition.

Coughs can also be classified as dry or productive. A dry cough does not produce mucus, while a productive cough does. Treatment options depend on the underlying cause; over-the-counter medications, home remedies, or medical intervention may be recommended based on the severity and duration of the cough. If a cough is persistent, accompanied by other symptoms like fever, shortness of breath, or chest pain, it’s advisable to seek medical advice for a proper diagnosis and treatment plan.

Nattokinase is an enzyme extracted from a traditional Japanese food called natto, which is made from fermented soybeans. This enzyme is thought to have potential health benefits, primarily for cardiovascular health. Nattokinase is believed to support the breakdown of fibrin in the blood, which can help improve circulation and reduce the risk of blood clot formation. As a dietary supplement, it is often marketed for its possible ability to promote healthy blood flow and cardiovascular function.

While some studies suggest that nattokinase may help reduce blood pressure and enhance overall heart health, research is still ongoing. As with any supplement, it is essential to consult with a healthcare professional before adding nattokinase to your regimen, especially if you are on blood-thinning medications or have underlying health conditions. Overall, while nattokinase might offer some intriguing health benefits, more comprehensive studies are needed to fully understand its efficacy and safety profile.

Based on user reviews, the time it typically takes to see results when taking this supplement for cough varies, with many users reporting positive effects within a short timeframe. For instance, one user noted that their husband's cough vanished within just one day of taking the supplement after recovering from COVID-19 (Read Review). Another user mentioned experiencing significant improvement after only two days of use, particularly in both sinuses and cough symptoms (Read Review).

Several other reviews echoed the sentiment that the supplement provides rapid relief. Users have reported that it effectively helps clear mucus and eases coughs within a brief period, attributing their recoveries to its use after viral infections like COVID-19 (Read Review) (Read Review). Overall, while individual experiences may vary, many users have experienced noticeable improvements in their cough symptoms relatively quickly after starting the supplement.

Users report a variety of improvements in their symptoms after using this supplement, particularly in relation to cough relief and mucus reduction. Many individuals have shared experiences of significant symptom alleviation, often within a short period. For instance, one user noted that after taking the supplement, their grandmother's long-standing cough of three years vanished, highlighting its potential effectiveness for chronic issues (Read Review). Another user experienced a rapid recovery, with their husband's cough disappearing within just a day of use (Read Review). Furthermore, users have indicated that the supplement helped them transition from dry to productive coughing, which is especially beneficial for those recovering from respiratory infections like COVID-19 (Read Review).

Additionally, several reviews mention enhanced breathing and the dissolution of mucus, with users stating that it clears phlegm effectively and aids in easing coughs associated with respiratory illnesses (Read Review). Others have reported noticeable improvements in their sinus symptoms and overall respiratory function after just a couple of days (Read Review). While these anecdotal experiences are promising, it's important to keep in mind that individual results can vary, and not every user may experience the same level of symptom relief.

Based on user reviews, many individuals found success in combining this supplement with other supplements for managing coughs and respiratory issues. For instance, one user mentioned pairing the supplement with Natto-Serra while treating pneumonia, which helped effectively thin the sputum and alleviate coughing (Read Review). Another user noted that the combination of enzymes in the supplement allowed both them and their spouse to quickly eliminate their COVID-related coughs without the need for additional medication (Read Review). These experiences suggest that the supplement may further enhance the effectiveness of other treatments when tackling respiratory challenges.

Additionally, some users have reported using the supplement as part of an ongoing regimen to control symptoms. For example, one user stated that taking it as a maintenance dose significantly relieved their smoker’s cough (Read Review). Overall, while users have reported positive outcomes from combining this supplement with others, as well as using it alone, it remains important to note that individual results can vary, and consulting with a healthcare provider is advisable before starting any new supplement regime.

Users often report positive outcomes when taking Nattokinase for treating cough, especially in post-viral scenarios such as after COVID-19. While specific dosage information is not consistently mentioned across reviews, many users seem to opt for a single capsule taken daily. For instance, one reviewer indicates taking it as a maintenance dose of one capsule per day, noting significant alleviation of their smoker's cough (Read Review). Another user highlights their husband's cough resolving within a day of taking it, emphasizing its effectiveness (Read Review).

While some users have not specified their doses explicitly, a common practice appears to be taking one capsule at a time, sometimes on an empty stomach to enhance efficacy. Reports of improvements in coughs accompanied by mucus and breathability also suggest that Nattokinase may help in thinning mucus, thereby providing relief (Read Review). Overall, while individual responses vary, a single daily dose seems to be a recommended approach for those looking to address coughing issues effectively.

Easier breathing
Breathing has become easier. Something is dissolving, that’s for sure. A few days later, it became easier for my nose to breathe, and I coughed up a small amount of mucus against the backdrop of being disease-free. I was surprised, as this never happened before. A small childhood scar has become less visible. I drank one capsule at night on an empty stomach.

Effective enzyme treatment
Excellent! I genuinely like this enzyme; it really works. It gradually alleviates inflammatory processes in the body and clears mucus from the upper respiratory tract. I began using it when I fell ill with COVID, and it swiftly transformed my dry cough into a productive one. A doctor also recommended it to a friend for endometriosis. I’m aware it’s effective for arthritis too. The capsules are quite small, making them easy to swallow. The dosage exceeds that of pharmacy alternatives, and I highly recommend it.

Cleared sputum effectively
Helps with coughs accompanied by phlegm. My dad took the Natto-Serra supplement from Dr Best while treating pneumonia to thin the sputum and for its antithrombotic properties. The sputum was cleared effectively. Good quality product. I recommend it! Please like if my review has been helpful.
